What Is a Marketing Experiment?

A marketing experiment is a structured, data-driven process to test specific ideas and strategies in your marketing campaigns. 

Instead of guessing what works, you run controlled tests to understand how changes impact key performance metrics like conversions, click-through rates, or sales.

How to Design Marketing Experiments?

1. Start with a research-based hypothesis

Your hypothesis should be supported by research or existing data, not just a guess.

For example: ‘Based on user heatmaps, I believe that moving the registration form to the top of the page will increase conversions by 15%.’ Sources for your hypothesis include:

  • Previous campaign data (e.g., low conversion rates or high bounce rates)
  • Market research or industry trends
  • User behavior analysis tools (like heatmaps, user recordings)

2. Design the experiment

Define exactly what you’re testing. This could be anything from changing button colors to testing new ad copy. 

Only test one variable at a time so you can accurately measure its impact. For example, if you're testing a new CTA on your landing page, keep everything else the same.

Use tools like Google Optimize, Optimizely, or even built-in A/B testing features in your CRM to split your audience between the original (control) version and the new (variant) version.

3. Choose your metrics carefully

Decide what success looks like for this experiment. Common metrics include:

  • Conversion rate: Do more users complete your goal (e.g., sign up, purchase)?
  • Click-through rate (CTR): Does the new version drive more clicks on key links or buttons?
  • Engagement metrics: Are users spending more time on the page or scrolling further down?

4. Run the experiment

Set it up and run it long enough to get a statistically significant amount of data. For example, if you’re testing a new landing page design, you might need to wait until you’ve had a few thousand visitors to see reliable results. 

Ensure you’re not cutting off the test too early; otherwise, you risk making decisions based on incomplete data.

5. Analyze the results

Once you’ve gathered enough data, compare the performance of the control and variant. If the new version performs better, you can confidently implement that change across the campaign.

Be precise with your analysis. For example, if you notice that a change increased conversions by 10% but also increased bounce rates, you may need to fine-tune other page elements.

6. Implement and iterate

If the test was successful, roll out the winning changes across all relevant areas of your campaign.

If the results are inconclusive or negative, refine your hypothesis and experiment again. Marketing experiments are an ongoing process of optimization.

Website Experiment Ideas to Improve Performance

1. Test the Impact of Page Load Speed on Conversion Rate

Improving page load speed can directly impact conversions. In 2023, the average website load time will be 2.5 seconds on desktop and 8.6 seconds on mobile, according to a study analyzing over 4 billion web visits. 

Hypothesis: If we reduce page load time from the current 8.6 seconds to under 3 seconds on mobile, we expect to see a 20% increase in conversions.

Steps to Run the Experiment:

1. Measure Your Current Page Load Speed: Use tools like Google PageSpeed Insights or GTmetrix to benchmark your current load times. Compare these with the industry averages (2.5 seconds on desktop, 8.6 seconds on mobile). Identify areas slowing down the site, such as large images, unoptimized scripts, or slow server response times.

For example, as seen in the performance report from GTmetrix for Popupsmart (screenshot below), the page achieved a 92% performance score and an LCP of 434 ms—well below the industry average for desktop pages, which is 2.5 seconds.

2. Optimize Your Website: Implement key optimizations to improve load speed:

  • Compress large images.
  • Minify CSS, JavaScript, and HTML files.
  • Enable browser caching and consider a content delivery network (CDN) to speed up load times globally.
  • Improve server response times by upgrading your hosting plan if necessary.

3. A/B Test Optimized vs. Original Page: Use A/B testing tools like Google Optimize to split traffic between your unoptimized control page and your newly optimized page. Keep all other elements (e.g., design, content) the same so that load speed is the only tested variable.

4. Key Metrics to Track: Your primary metric should be conversion rate, but secondary metrics like bounce rate and time on the page should also be monitored to understand how load speed affects overall user behavior.

5. Run the Experiment: Run the test until you have enough data to make reliable conclusions. 

6. Analyze the Results: Compare the conversion rates between your control and variant pages. 

2. Experiment with Landing Page Copy Changes

Changing your landing page copy can significantly impact conversions. Sometimes, minor tweaks in a call-to-action (CTA) or headline wording can influence how users engage with your site. 

In fact, at Popupsmart, we've updated our main CTAs to reflect a more actionable and clear message. As you can see in the screenshot below, the CTAs now read “Get Popupsmart Free” and “Create a Free Account,” which better convey the value proposition compared to more generic CTAs like “Get Started.”

Popupsmart landing page ss
Hypothesis: Changing the CTA from "Get Started" to "Join Now" will increase conversions by 10%.

Steps to Run the Experiment:

1. Review Current Landing Page Copy: Analyze your CTA, headlines, and body copy. Identify areas where the language is unclear or lacks a strong emotional pull. Check your conversion rates as the baseline for comparison.

2. Create an Alternative Copy: Write variations of your CTA and key headlines. For example:

  • Current CTA: "Get Started"
  • New CTA: "Join Now"
    This small change creates urgency and implies membership, which can make users feel like they're part of something exclusive.

3. A/B Test Your Copy: Use a tool like Google Optimize or Optimizely to run an A/B test. Split your traffic evenly between two versions of the landing page:

  • Version A (control): Original copy with "Get Started"
  • Version B (variant): New copy with "Join Now"

Ensure all other elements (images, design) remain the same to isolate the impact of the copy change.

4. Select Metrics for Success: Your primary metric is conversion rate—the percentage of visitors who take your desired action (e.g., sign up, make a purchase). You can also monitor other key engagement metrics, such as click-through rates (CTR) for the CTA.

5. Run the Experiment: A good rule of thumb is to wait until you have a few hundred or thousand visitors on each version, depending on your traffic levels.

6. Analyze the Results: Compare the conversion rates for each version. 

3. Test Popup Timing for Lead Capture

Popup Timing is crucial in determining the effectiveness of your popups in capturing leads. Displaying a popup too soon can annoy visitors, while showing it too late might mean missing an opportunity. 

Hypothesis: Delaying the popup display by 60 seconds will increase lead conversions by 15%.

Steps to Run the Experiment:

1. Assess Current Popup Timing: Review when your popup currently appears (e.g., immediately, after 5 seconds, after scrolling). Gather baseline data on how well your popup converts leads.

Determine if the current timing could be disrupting user experience or failing to catch visitors’ attention.

2. Create Time Variations for the Popup: Adjust your popup display timing and create different variations. For example:

  • Version A (control): Popup appears after 5 seconds.
  • Version B (variant): Popup appears after 60 seconds.

3. A/B Test the Popup Timings: Use popup builder tools with A/B testing features, like Popupsmart, to split your audience between different popup timings. As seen in the screenshot below, Popupsmart allows you to set the timing precisely and run A/B tests with ease. This flexibility lets you test variations like:

  • Version A will show the popup after 5 seconds.
  • Version B will delay the popup by 60 seconds.
  • Ensure all other popup elements (design, copy, CTA) remain the same to isolate timing as the sole variable.

4. Define Key Metrics: The key metric to track is lead conversion rate—the percentage of visitors who fill out the form or take the action prompted by the popup. Additionally, monitor the bounce rate and time spent on the page to ensure the delayed popup doesn’t cause visitors to leave early.

5. Run the Experiment: This might depend on your traffic, but aim for at least a few hundred interactions with both versions' popups.

6. Analyze the Results: After gathering enough data, compare the conversion rates between the two versions. 

4. Test Removing Hero Image for Above-the-Fold Text

Hero images can look great but might not always drive conversions. Replacing them with value-focused text could increase engagement and boost conversions.

Hypothesis: Replacing the hero image with value proposition text will increase conversions by 15%.

For example, Semrush has included value-focused text on its website instead of using a hero image.

Semrush has included value-focused text on its website instead of using a hero image

Steps to Run the Experiment:

1. Analyze Current Setup
Review your landing page metrics like scroll depth, bounce rate, and conversion rate to set a baseline.

2. Create a Text-Only Version
Replace the hero image with a short, clear value proposition that highlights the key benefits of your product or service.

3. A/B Test Versions

  • Version A (control): Original page with hero image.
  • Version B (variant): Page with hero image replaced by text.

Keep all other elements the same.

4. Track Key Metrics
Focus on scroll depth and conversion rate as primary metrics. Also, monitor bounce rate and time spent on page.

5. Run the Experiment
Let the test run long enough to get reliable results, depending on your traffic.

6. Analyze Results
Compare performance between the versions. If the text-only version improves conversions as predicted, roll out the change across other pages.

5. Implement Personalized Homepages Based on User Behavior

By showing relevant content, offers, or products based on a user's past actions, you can create a more engaging experience.

Hypothesis: Personalized homepages based on user behavior will increase conversions by 20%.

Steps to Run the Experiment:

1. Segment Your Audience: Start by identifying key user behaviors you want to target, such as:

  • Visitors who have viewed specific product categories.
  • Users who have abandoned carts.
  • Returning customers vs. first-time visitors.

2. Set Up Personalization Triggers: Use a tool like Optimizely or Dynamic Yield to set up personalized content triggers. For example:

personalized product recommendation banner from nyx
  • Offer a discount or free shipping for cart abandoners upon their return.

3. Create Personalized Homepage Versions: Develop different homepage versions based on user behavior. Examples:

  • Version A (control): Standard homepage for all users.
  • Version B (variant): Personalized homepage with dynamic product recommendations or offers based on previous user actions (e.g., browsing history or cart status).

A/B Test the Personalization: Split your traffic into two groups:

  • One group sees the standard homepage.
  • The other group sees a personalized homepage based on their past behavior.

4. Track Key Metrics: Monitor the conversion rate as the main metric. Additionally, track:

  • Average session duration: Do users spend more time on the personalized page?
  • Engagement rate: Are users interacting more with personalized content?
  • Bounce rate: Does personalization reduce the likelihood of users leaving immediately?

5. Run the Test for Enough Time: Allow the experiment to run until you have enough data for a statistically significant result. Depending on your traffic, this could take a week or longer.

6. Analyze the Results: Did the personalized homepage lead to a 20% increase in conversions as expected? If so, consider expanding personalization to other areas of the site.

Content and Messaging Experiment Ideas

6. Testing Emotional Messaging in Email Campaigns

Subject lines with urgency and exclusivity can significantly boost email engagement. According to Invesp, subject lines that create a sense of urgency or exclusivity can result in a 22% higher open rate. 

Hypothesis: Subject lines with emotional urgency or exclusivity will increase open rates by 22%.

For example, below is an email titled “October Deals End At Midnight.” The urgency in both the subject line and the email content can increase open rates.

email example from bakley to show subject line with emotional trigger

Steps to Run the Experiment:

1. Create Consistent Subject Line Versions Develop two versions of the subject line that keep the topic the same while testing the emotional trigger:

  • Version A (control): Neutral messaging (e.g., “Your Weekly Update”).
  • Version B (variant): Emotional messaging with urgency (e.g., “Don’t Miss Out! Your Weekly Update Inside”).

Both versions refer to the same content, but Version B adds a sense of urgency to trigger action.

2. Set Up the A/B Test: Use an email marketing platform like Mailchimp or Klaviyo to split your audience evenly and run the A/B test:

  • Version A is sent to half of your audience with neutral messaging.
  • Version B is sent to the other half with urgency-based messaging.

Keep all other factors (design, timing, segmentation) consistent to isolate the impact of the subject line.

3. Track Key Metrics: The primary metric is the open rate, which shows how well the subject line performs. Secondary metrics include:

  • Click-through rate (CTR): Are more users clicking through the email in Version B?
  • Unsubscribe rate: Ensure the emotional messaging doesn’t increase unsubscribe rates.

4. Run the Experiment
Let the test run long enough to gather meaningful results, usually over several days, depending on your audience size.

5. Analyze the Results: Compare the open rates between the two versions. Emotional messaging with urgency improved open rates by the predicted 22%, as supported by Invesp data. Also, check whether the CTR improved and if any changes in unsubscribe rates occurred.

6. Implement and Refine
If the emotional subject line outperforms the neutral one, apply urgency or exclusivity to future campaigns.

7. Long-Form Content vs. Short-Form Content in Blogs

Deciding whether long-form or short-form content drives better engagement is a key question in content marketing. Testing both formats can help you determine which resonates more with your audience, boosts session duration, and reduces bounce rates.

Hypothesis: Long-form content (2,000+ words) will increase average session duration and reduce bounce rates by 20% compared to short-form content (under 1,000 words), as it provides more in-depth value and encourages longer engagement.

Steps to Run the Experiment:

1. Choose a Blog Topic: Select a topic that is relevant to your audience and can be effectively covered in both long-form and short-form formats. The subject should be the same for both versions to ensure accurate comparisons.

Example: "The Ultimate Guide to Social Media Strategy."

Create Long-Form and Short-Form Versions: Write two versions of the blog post:

  • Version A (control): Short-form content (500-1,000 words), providing concise coverage of key points.
  • Version B (variant): Long-form content (2,000+ words), offering in-depth explanations, examples, and comprehensive insights.

Both versions should be of high quality and address the same topic thoroughly.

2. A/B Test the Content: Publish both versions of the blog and direct an equal amount of traffic to each version:

  • Version A: The short-form blog.
  • Version B: The long-form blog.

Use A/B testing tools like Google Optimize or HubSpot to split traffic and track the performance of each version.

3. Monitor Key Metrics: Focus on the following metrics to assess performance:

  • Average session duration: How long are users spending on the page?
  • Bounce rate: Are users leaving the site after viewing the content, or are they staying to explore more?
  • Page views: Does one version lead to more clicks or engagement with related content?

4. Run the Experiment for a Meaningful Duration: Allow the test to run for several weeks to gather statistically significant data. 

5. Analyze the Results: Compare the performance of the two versions. 

6. Apply the Findings: If long-form content leads to better engagement, focus on producing more in-depth posts. If short-form content performs better, prioritize brevity while ensuring it delivers value to your readers.

8. A/B Test Storytelling in Marketing Emails

By testing the use of storytelling in your email campaigns, you can determine if it leads to better open and click-through rates compared to traditional, straightforward messaging.

Hypothesis: Emails that use storytelling will have a 15% higher click-through rate (CTR) than emails with standard promotional content.

Steps to Run the Experiment:

1. Create Two Email Versions

  • Version A (control): A standard promotional email focusing on the key offer or announcement (e.g., “Shop Our Fall Collection Now!”).
  • Version B (variant): A storytelling-focused email that shares a narrative related to the product or brand (e.g., “How Our Fall Collection Was Inspired by Nature”).

2. A/B Test the Emails: Use email marketing platforms like Mailchimp or Klaviyo to split your audience evenly between the two versions.

  • Version A provides direct promotional content.
  • Version B includes a story that builds emotional engagement before introducing the offer.

3. Track Key Metrics: The primary metric is the click-through rate (CTR), showing how many users clicked on links within the email. Additional metrics include:

Open rate: Did the storytelling subject line encourage more opens?

Engagement rate: Are users spending more time reading the storytelling email?

4. Run the Test for a Valid Sample Size: Allow the experiment to run long enough to collect statistically significant data. This might take a few days depending on your email list size.

5. Analyze the Results: Compare the CTR and other metrics between the two versions. Did the storytelling approach lead to the predicted 15% increase in CTR? Also, assess if it had an impact on open rates and overall engagement.

6. Implement Findings: If storytelling proves effective, incorporate it more frequently in future campaigns. Continue refining your narrative strategies to connect emotionally with your audience while balancing the promotional aspects.

9. Dynamic Text Replacement in Popup Campaigns

Dynamic text replacement (DTR) can personalize popup messages based on the user’s behavior, preferences, or data. This experiment aims to see whether personalized popups increase click-through rates (CTR) or conversions compared to static ones.

Hypothesis: Popups using dynamic text replacement will boost engagement rates by 20% compared to static popups.

Steps to Run the Experiment:

1. Set Up Dynamic Text Replacement in Popups

  • Version A (control): Use a standard popup with static content (e.g., "First time here?”)
  • Version B (variant): Use dynamic text replacement to personalize the popup. For example, use Popupsmart’s smart tags: Dynamic Text: "Welcome, {{customerInfo.firstName|fall=visitor}}! First time here?
dynamic text replacement feature from Popupsmart

2. Run the A/B Test: Create two versions of the popup:

  • Version A shows the static message to half of the visitors.
  • Version B uses dynamic text, addressing users by name if available.

Use a tool like Popupsmart to set up this A/B test and split traffic between the two versions.

3. Track Key Metrics: The primary metric is the click-through rate (CTR) of the popup’s call-to-action.

Additional metrics:

  • Conversion rate: Are users more likely to complete the desired action (e.g., signing up or purchasing) with personalized content?
  • Engagement rate: Do users engage more with the dynamic version of the popup?

5. Run the Experiment for a Valid Sample: Let the test run long enough to gather sufficient data, which may take a week or more, depending on traffic.

6. Analyze the Results: Compare the performance of static vs. dynamic popups in terms of engagement and conversion rates.

Evaluate which dynamic elements (e.g., name-based greetings) had the most significant impact.

10. Test the Impact of Adding Social Proof to Landing Pages

Social proof helps build trust with visitors, making them more likely to take action, especially when they see others have had a positive experience with your product or service.

Hypothesis: Adding customer testimonials to landing pages will increase conversion rates by 15%.

For example, Blume added both a dermatologist’s review of the products and honest reviews from people who have purchased them on its landing page.

Blume added both a dermatologist’s review of the products and honest reviews from people who have purchased them on its landing page.

Steps to Run the Experiment:

1. Identify Key Landing Pages: Choose high-traffic landing pages that serve as gateways to conversions, such as product or service pages, checkout pages, or lead generation pages.

2. Select Relevant Social Proof: Gather customer testimonials, star ratings, case studies, or endorsements that are directly related to the product or service featured on the landing page.

  • Version A (control): The original landing page without social proof.
  • Version B (variant): The same landing page with social proof added above the fold or near the CTA.

3. A/B Test the Landing Pages: Use A/B testing tools like Google Optimize or VWO to split your audience between:

  • Version A: No social proof.
  • Version B: Social proof prominently displayed.

4. Track Key Metrics: The primary metric is conversion rate—the percentage of visitors who complete the desired action (e.g., making a purchase or filling out a form). Secondary metrics include:

  • Engagement rate: Are users interacting with the social proof (e.g., clicking on testimonials or reviews)?
  • Bounce rate: Does social proof reduce the number of visitors who leave immediately?

5. Run the Test for Statistical Significance: Allow the test to run long enough to gather significant data—this might vary depending on your traffic levels but aim for at least several hundred conversions to make confident decisions.

6. Analyze the Results: Compare the conversion rates between the two versions. Did the social proof lead to the predicted 15% increase? If it performs well, consider integrating social proof across other high-conversion pages.

Conversion Rate Optimization (CRO) Test Ideas

11. Multi-Step Forms vs. Single-Step Forms

Multi-step forms break the user journey into smaller, digestible parts, which can reduce cognitive overload and form abandonment, while single-step forms present all required fields at once. Testing both approaches will help you understand which form structure leads to higher completion rates.

Hypothesis: Creating multi-step forms will reduce form abandonment by 20% compared to single-step forms.

Steps to Run the Experiment:

1. Choose a Key Conversion Point: Select a form that plays a pivotal role in conversions, such as sign-up, lead generation, or checkout forms. Ensure it's a high-traffic page where small improvements can have a significant impact.

2. Design the Form Variations

  • Version A (control): The single-step form where all fields (e.g., name, email, address, payment info) are presented at once.
  • Version B (variant): A multi-step form that breaks down the same fields into steps (e.g., Step 1: Basic info, Step 2: Payment, Step 3: Confirmation). Use progress bars to show users how far along they are.

3. A/B Test the Form Structures: Use tools like Popupsmart or HubSpot to create the A/B test:

  • Version A: Single-step form.
  • Version B: Multi-step form with a logical flow.

4. Track Key Metrics: The primary metric is the form completion rate, which shows how many users successfully submit the form. Also, monitor:

  • Abandonment rate: At what stage are users dropping off, especially in the multi-step form?
  • Conversion rate: Does the multi-step form lead to higher conversions as users complete the process?

5. Run the Test for Enough Data: Run the experiment long enough to collect statistically significant results, especially if your traffic is lower. 

6. Analyze the Results: Did the multi-step form reduce abandonment and lead to a 20% improvement in form completion? If successful, this approach could be applied to other complex forms across your site.

12. Test Trust Signals on Checkout Pages

Trust signals like security badges, recognizable payment icons, and third-party endorsements play a crucial role in checkout page optimization. 

According to a 2024 study from Baymard Institute featured in Statista, 25% of consumers abandon their checkout process because they don’t trust the site with their credit card information. 

Statista's statistics about why consumers abandon their orders

By optimizing the placement and type of trust signals, you can help reduce this abandonment and improve conversion rates.

Hypothesis: Optimizing the placement and types of trust signals on checkout pages will reduce cart abandonment and improve conversion rates by 10%.

Steps to Run the Experiment:

1. Review Current Trust Signals: Identify what trust signals (e.g., SSL certificates, recognizable payment icons) are currently on your checkout page. Ensure they are up-to-date and clear.

2. Set Up Trust Signal Variations:

  • Version A (control): The original checkout page with trust signals in their current format.
  • Version B (variant): Optimize the placement and types of trust signals by:

➡️ Placing SSL certificates and security badges near the payment form.

➡️ Adding customer reviews or testimonials near the CTA to boost confidence.

➡️ Displaying payment icons (Visa, MasterCard, PayPal) near the "Place Order" button to reinforce credibility.

3. A/B Test the Variations: Use A/B testing tools like Google Optimize to run the test:

  • Version A: The control version with the current trust signal setup.
  • Version B: The optimized version with better placement and additional trust indicators.

4. Track Key Metrics: The primary metric is the conversion rate. Also track:

  • Cart abandonment rate: Did the optimized trust signals reduce hesitation at checkout?
  • Time on page: Are users completing purchases faster?

5. Run the Test Long Enough for Reliable Data: Run the test for a sufficient time to gather reliable data based on traffic levels.

6. Analyze the Results: Compare the cart abandonment rates and conversion rates between the two versions. 

13. Scarcity Messaging on Product Pages

Scarcity messaging (e.g., "Only 3 left in stock!") is a powerful psychological tactic to drive urgency and encourage users to purchase quickly. By adding scarcity elements to your product pages, you can increase the sense of urgency and drive faster decision-making.

Hypothesis: Adding scarcity messaging to product pages will increase sales by 15%.

Steps to Run the Experiment:

1. Identify High-Impact Product Pages: Select product pages that have steady traffic but could benefit from a higher conversion rate. Scarcity messaging works particularly well for high-demand items or limited-stock products.

2. Implement Scarcity Messaging

  • Version A (control): The original product page with no urgency messaging.
  • Version B (variant): Add scarcity messaging near the product title or purchase button, such as:
Magic spoon's product label

➡️ "Only 3 left in stock!"

➡️ "Low stock—order now!"

➡️ "Limited-time offer—ends in 24 hours!"

3. A/B Test the Product Pages: Use A/B testing tools like Optimizely or Google Optimize:

  • Version A: Product page without scarcity messaging.
  • Version B: Product page with scarcity messaging added above or next to the CTA button.

4. Track Key Metrics: Focus on sales conversion rate as the main metric. Additionally, track:

  • Average order value (AOV): Does scarcity encourage users to buy more?
  • Time on page: Does scarcity messaging lead to quicker decision-making?

5. Run the Test Long Enough for Reliable Data: Run the test for a sufficient period based on your traffic levels. Ensure the scarcity message feels genuine and isn’t overused, as this could harm credibility.

6. Analyze the Results: Did the scarcity messaging increase sales by the predicted 15%? Evaluate whether the sense of urgency positively impacted conversion rates without negatively affecting user experience.

14. Experiment with Personalized Retargeting Ads

Personalized retargeting ads can increase engagement and conversions by delivering tailored content to users based on their past behavior on your site. The key is to refine the approach, ensuring the retargeting ads are personalized enough to be impactful without wasting ad spend on generic campaigns.

Hypothesis: Personalized retargeting ads that include product recommendations or cart reminders will increase return visits and conversions by 15% compared to generic ads.

Steps to Run the Experiment:

1. Segment Your Audience Based on Behavior: Segment your audience into specific groups based on their actions, such as:

  • Viewed product pages but did not purchase.
  • Abandoned carts.
  • Spent significant time on particular content or product categories.

2. Create Tailored Retargeting Ads

  • Version A (control): Generic retargeting ads (e.g., “Come Back and Shop!”).
  • Version B (variant): Personalized retargeting ads (e.g., “You left [Product] in your cart. Come back now for a 10% discount!” or “Check out similar items to [Product Name]!”).

3. A/B Test the Retargeting Ads: Use ad platforms like Google Ads or Facebook Ads to set up an A/B test:

  • Version A: Generic messaging with no specific reference to user behavior.
  • Version B: Personalized ads tailored to user actions (viewed products, abandoned carts).

4. Track Key Metrics: Focus on return visits, click-through rate (CTR), and conversion rate to see if personalized ads bring users back and drive more purchases.

5. Run the Experiment for Meaningful Data: Run the test over several weeks to gather significant data. Target different behavior-based segments to assess the effectiveness of personalization across multiple groups.

6. Analyze the Results: Compare the performance between personalized and generic ads. 

15. Countdown Timers for Promotions

Countdown timers are effective in creating urgency during promotions, but testing their design, placement, and length can optimize their impact further. Rather than simply testing whether to use countdown timers, focus on how to implement them most effectively.

Hypothesis: Optimizing the design and placement of countdown timers will increase conversion rates by 10% compared to generic timers.

Steps to Run the Experiment:

1. Choose a Time-Sensitive Promotion: Select an ongoing promotion or limited-time offer to run this experiment. The promotion should have a clear end date to create urgency.

2. Set Up Variations of Countdown Timers

  • Version A (control): Standard countdown timer placed near the product or pricing (e.g., default font, color).
  • Version B (variant): Test different designs (e.g., bold fonts, bright colors) and placements (e.g., at the top of the page or near the CTA button). You can also experiment with shorter or longer countdown periods to see how timing impacts urgency.

3. A/B Test the Variations
Use tools like Optimizely or Google Optimize:

  • Version A: Standard countdown timer without special design or placement.
  • Version B: Countdown timer with optimized design and strategic placement.

4. Track Key Metrics
Monitor conversion rate and time spent on page to assess how design, placement, and countdown length influence urgency. Also, track cart abandonment rates to see if the timer helps reduce hesitation.

5. Run the Test Over the Entire Promotional Period
Ensure the experiment runs throughout the promotion to gather complete data on how users respond to different variations.

6. Analyze the Results
Compare the performance of the different designs and placements. 

Lead Generation Experiment Ideas

16. Test Video Testimonials vs. Text Testimonials

Testimonials are a powerful form of social proof, but video testimonials can add a deeper layer of authenticity compared to text-based ones. 

Hypothesis: Video testimonials will increase conversion rates by 20% compared to text testimonials.

Steps to Run the Experiment:

1. Choose High-Impact Pages: Select product pages, service pages, or landing pages where testimonials can directly influence the user’s decision-making process.

2. Implement Video and Text Versions

  • Version A (control): Use text-based testimonials (e.g., “This product changed my life!” with customer name and photo).
  • Version B (variant): Replace or supplement text testimonials with video testimonials (e.g., a customer sharing their experience with your product or service in a 30-second video).

3. A/B Test the Testimonials: Use tools like Google Optimize or Optimizely to set up the test:

  • Version A: Text-only testimonials on your page.
  • Version B: Video testimonials placed in the same location as the text versions.

4. Track Key Metrics: Focus on conversion rate as the primary metric to see if the video testimonials drive more purchases or sign-ups. Also, monitor:

  • Engagement rate: Are users spending more time on the page when video testimonials are present?
  • Bounce rate: Does the presence of video reduce bounce rates?

5. Run the Experiment for Reliable Data: Run the test long enough to gather statistically significant results, ensuring the variations have sufficient exposure to your audience.

6. Analyze the Results: Compare the performance of video testimonials to text testimonials. Did video testimonials drive the predicted 20% increase in conversions? How did they impact engagement rates and time on page?

17. Gated vs. Ungated Content for Lead Capture

Gating content—requiring users to provide contact information in exchange for access—can be an effective way to generate leads, but it may also reduce the number of users willing to engage with the content.

Hypothesis: Gated content will capture higher-quality leads, while ungated content will generate more overall leads.

Steps to Run the Experiment:

1. Choose High-Value Content
Select premium content (e.g., whitepapers, e-books, industry reports) that is likely to attract your target audience. Ensure the content offers real value to users.

2. Set Up Gated and Ungated Versions

  • Version A (control): Ungated content that is freely accessible without requiring contact information.
  • Version B (variant): Gated content that requires users to fill out a form (e.g., name, email) to access the content.

3. A/B Test the Gated and Ungated Versions
Use tools like HubSpot or Unbounce to set up the test:

  • Version A: Freely accessible content.
  • Version B: Gated content that requires users to submit contact information before downloading or accessing the material.

4. Track Key Metrics: The primary metrics are:

  • Lead quality: Evaluate the quality of leads captured (based on criteria such as email engagement, follow-up success, or lead scoring).
  • Lead volume: Track how many users fill out the form (gated content) vs. how many users engage with the content (ungated).
  • Engagement rate: Does ungated content lead to higher engagement (e.g., more time spent on page, more content downloaded)?

5. Run the Experiment for a Sufficient Time: Allow enough time to gather both lead quality and volume data for each version. Consider running the test over several weeks to capture a representative sample of leads.

6. Analyze the Results: Compare the number of leads generated by the gated content to the engagement and reach of the ungated content. 

18. Interactive Quizzes vs. Static Lead Forms

By making the lead capture forms interactive and fun, you can encourage more users to provide their contact information.

Hypothesis: Interactive quizzes will generate 20% more leads than static lead forms by increasing user engagement.

Steps to Run the Experiment:

1. Choose the Lead Magnet: Select a lead magnet that could benefit from an interactive quiz (e.g., personalized product recommendations, industry reports). The quiz should align with your audience’s interests.

2. Create the Interactive Quiz and Static Form Versions

  • Version A (control): Standard static lead form asking for basic information (e.g., name, email, job title) in exchange for content.
  • Version B (variant): An interactive quiz that asks a series of personalized questions (e.g., “What’s your marketing style?”) before collecting contact information.

3. A/B Test the Quiz and Form
Use platforms like Typeform or Popupsmart for the interactive quiz and your regular lead capture tools for the static form

  • Version A: Static form asking for contact details upfront.
  • Version B: Quiz that asks engaging questions, leading to lead capture after completion.

4. Track Key Metrics: Focus on:

  • Lead volume: How many users complete the quiz or form and provide their information?
  • Engagement rate: Do users spend more time interacting with the quiz?
  • Completion rate: Are more users finishing the quiz compared to filling out the static form?

5. Run the Experiment for Enough Data: Allow the test to run for several weeks, especially if your site traffic is lower, to gather meaningful results from both versions.

6. Analyze the Results: Compare the number of leads generated by the interactive quiz versus the static form. 

Lead Nurturing and Customer Retention Experiment Ideas

19. Testing Re-Engagement Campaigns for Inactive Users

Whether through personalized emails, special offers, or reminders, re-engagement campaigns can reignite interest and restore lost customers.

Hypothesis: Re-engagement campaigns with personalized offers will reactivate 10% of inactive users.

Steps to Run the Experiment:

  1. Segment Your Inactive Users: Define what "inactive" means for your business (e.g., no engagement for 60 days). Segment users who have not opened emails, visited your site, or made purchases in that time.
  2. Create Two Re-Engagement Campaign Versions
    • Version A (control): Standard re-engagement email (e.g., “We Miss You! Come Back and Shop Now”).
    • Version B (variant): Personalized re-engagement email with a special offer or personalized content (e.g., “Here’s 10% Off to Welcome You Back” or “Check Out New Items Based on Your Past Purchases”).
  3. A/B Test the Campaigns: Use your email marketing platform (e.g., Mailchimp, Klaviyo) to send the two variations to your inactive users:
    • Version A: Generic re-engagement campaign.
    • Version B: Personalized campaign with an offer tailored to the user’s previous behavior.
  4. Track Key Metrics: Focus on:
    • Re-engagement rate: How many inactive users returned and interacted with your site or emails after the campaign?
    • Conversion rate: Did users make a purchase or take action after re-engaging?
    • Unsubscribe rate: Did personalized campaigns result in fewer unsubscribes?
  5. Run the Experiment Over a Set Time Period: Monitor user behavior for a set period (e.g., 2–4 weeks) after sending the re-engagement emails to see the long-term effects of the campaign.
  6. Analyze the Results: Compare the re-engagement rate between personalized and generic campaigns.

20. Automated Loyalty Program Emails

By sending targeted loyalty emails at key milestones, you can keep customers engaged and incentivize them to continue purchasing.

Hypothesis: Automated loyalty program emails will increase repeat purchases by 15%.

Steps to Run the Experiment:

1. Identify Key Loyalty Triggers: Set up automated emails based on key milestones, such as:

  • Reaching a certain number of purchases.
  • Time-based milestones (e.g., six months of customer loyalty).
  • Accumulating loyalty points.

2. Set Up Automated Emails

  • Version A (control): No loyalty emails sent to customers.
  • Version B (variant): Automated loyalty program emails triggered by milestones (e.g., “You’ve earned 500 points! Here’s a 10% discount for your next purchase”).

3. A/B Test the Emails: Use email platforms like Klaviyo or Mailchimp to automate and A/B test:

  • Version A: No automated loyalty emails.
  • Version B: Automated loyalty emails at key customer milestones.

4. Track Key Metrics Focus on:

  • Repeat purchase rate: Are users making more purchases after receiving loyalty emails?
  • Customer lifetime value (CLV): Do customers engaged with the loyalty program spend more over time?
  • Email open and click-through rates (CTR): Are customers engaging with the emails?

5. Run the Experiment Over a Sufficient Time Period
Run the test over several months to capture sufficient data on the long-term impact of loyalty emails on customer behavior.

6. Analyze the Results
Compare the repeat purchase rate and CLV between the two groups. 

21. Satisfaction Surveys to Reduce Churn

Customer satisfaction surveys provide invaluable insights into how happy your customers are with your product or service. By gathering this feedback and acting on it, you can reduce churn by addressing pain points before customers leave.

Hypothesis: Sending post-purchase satisfaction surveys will reduce customer churn by 10%.

Steps to Run the Experiment:

1. Identify Key Survey Triggers: Set up automated surveys to be sent after important customer interactions, such as:

  • Immediately after a purchase.
  • After a customer service interaction.
  • After a set period of time as a customer.

2. Create Two Versions of Post-Purchase Experience

  • Version A (control): No follow-up survey sent to customers after a purchase or interaction.
  • Version B (variant): Automated satisfaction survey sent (e.g., “How was your recent experience with [Product]?” with a scale from 1 to 10).

3. A/B Test the Surveys: Use tools like SurveyMonkey or Typeform:

  • Version A: Customers receive no follow-up survey.
  • Version B: Customers receive a satisfaction survey after their purchase or customer service interaction.

4. Track Key Metrics Focus on:

  • Churn rate: Measure how many customers stopped interacting with your brand after receiving a survey.
  • Customer feedback: Gather responses from the surveys to identify trends or recurring issues.
  • Response rate: Track how many customers are completing the survey to ensure you have enough data.

5. Run the Experiment for a Set Period: Run the experiment for at least 4–6 weeks to gather sufficient data on churn rates and customer responses.

6. Analyze the Results: Compare churn rates between the customers who received the surveys and those who didn’t. 

Wrap Up

Marketing experiments are a powerful way to optimize strategies and drive better results by making informed, data-driven decisions. 

By testing different elements of your campaigns—whether it’s adjusting copy, refining website designs, personalizing user experiences, or improving lead generation methods—you gain valuable insights into what truly resonates with your audience. 

The examples presented here demonstrate the wide variety of experiments you can run to improve key performance metrics like conversion rates, engagement, and customer retention.

Frequently Asked Questions

1. What are the benefits of marketing experiments?

➕ Targeted Performance Improvements: Marketing experiments allow you to test specific aspects of your campaigns, such as the color of a CTA button or the placement of a lead form, and measure their impact on user behavior. For example, testing two different checkout page designs can reveal which version reduces cart abandonment.

➕ Quantifiable Results: They provide measurable insights. For instance, testing the impact of personalized email subject lines on open rates can show whether a personalized approach (e.g., "John, check out these deals!") drives 22% more opens compared to a general subject line.

➕ Cost Efficiency: Experiments help optimize marketing spend by identifying the most cost-effective strategies. For example, testing different ad creatives (videos vs. images) can show which format generates higher returns on ad spend, helping you focus your budget on the most effective options.

➕ Lower Customer Acquisition Costs (CAC): By optimizing individual parts of the funnel through experiments (such as improving ad targeting or email copy), you can reduce overall CAC. For instance, if a landing page tweak increases conversions, it reduces the cost per customer.

2. What is an example of a field experiment in marketing?

An example of a field experiment in marketing is price sensitivity testing for a product. A company may launch an A/B test where one group of customers sees a product priced at $19.99, and another group sees the same product priced at $24.99. The goal is to determine which price point results in higher sales volume or revenue.

For example, an online retailer might run this experiment on their product page, analyzing both the conversion rates (number of purchases) and the total revenue generated from each group. The result will provide concrete insights into customer price sensitivity in real-world conditions.

3. What is experimentation in digital marketing?

Experimentation in digital marketing refers to systematically testing different variables in online campaigns to see which version drives better results. It can involve A/B testing or multivariate testing across various digital channels like websites, emails, or ads.

For instance:

  • A company might experiment with ad targeting on Facebook by testing two different audience segments—one based on interests (e.g., fitness enthusiasts) and one based on demographics (e.g., 18-25-year-olds). The goal would be to determine which group produces more conversions.
  • Another example in SEO could involve testing the impact of adding internal linking to long-form blog posts to see if it improves organic rankings.

These experiments provide valuable feedback on which strategies are most effective in driving traffic, engagement, and sales.
