According to Professor Robert Cialdini, people are more likely to act if they see others have already.

The concept is old, but as the accessibility of the internet has enhanced, social proofing has become today's shape.

Why Social Proof Works?

Ever since the primordial ooze, people always tend to ask for advice and confirmation before doing something for themselves. This is the reason why people still like asking their friends for recommendations or following the world's trends.

No matter how much value you include on your landing page, the prospects have absolutely no idea about what they will get. The essential point of social proof is to prove that other people have used your products, which actually solves a problem.

Social Proof Statistics

  • A study by Monash University shows that the most significant factor in increasing demand in 442 hotels was not necessarily the quality of service or design but the number of positive reviews on social media. It works for all of us, right? Don't you look at the hotel reviews before you pay $300 for a night to a hotel you have never been to?

  • Rent the Runway, a fashion business, has discovered that conversion rate increases by 200% paid search when an influential blogger or magazine refers to the brand.

User Generated Reviews

While case studies and testimonials are surpassing, people will trust more in the opinions of people who are like them. This is why user-generated reviews are the most powerful social proof type.

Not all reviews have the same weight as Trustpilot CEO Peter Mühlmann said: "Using a closed platform is like asking your own mother if you’re handsome."

Social reviews from third-party platforms are more recognized and trusted. Therefore, you need to become visible in the platforms like Trustpilot and G2. Create an account, give your company details, and encourage your customers to write reviews on these platforms.

Purchasing is mostly an emotional decision rather than being a logical one. Soon, you will be enjoying the increase in your brand's engagement and conversion rates!

Number of Social Media Followers

A straightforward way to demonstrate social proof is to present the number of social media followers your company has. It is an excellent strategy to build trust because a brand cannot manipulate these numbers.

The number of social media followers reinforces to your audience how connectable your brand is, how many prospects actually follow, and trust your brand.

Think that what if a website visitor sees that one of her friends is also following your brand? She would become more likely to trust your brand and purchase something from your store.

Wisdom of the Crowd

Wisdom of the crowd is a great way to say, "What do you wait for? Everyone else has joined us." By letting your users know how many people are using your service, you will impress them and boost your subscribers efficiently.

Expand Your Influence with Social Media Takeovers

Social media takeovers are significant to reach your potential customers who are not necessarily familiar with your company. An influencer or an expert take over your social media accounts for a certain amount of time and shares related posts with your brand.

It does not only leverage the relationship with that person's audience, but he accesses to your audience differently, too.

Share Media Mentions

Has your company been featured in a media outlet? Then, definitely excerpt media mentions and show them on your website to establish authority.

It does not matter whether your brand was mentioned in a magazine, TV program, or podcast interviews. It does not attract the attention of your potential customers, but they will be more likely to visit your website to learn more about you.

Include Well-Known Client Logos

Including your famous client logos in your pages is an extremely persuasive social proof strategy. Think about it! You are showing that very successful and giant companies prefer you. What happens? Positive adoption: smaller ones would adapt to your brand faster.

You can also show these logos on your popup campaigns and in your email marketing campaigns as well. Believe me; it will make a difference!

Have Best Seller Banner

Having your "best seller" products with a relevant banner increases conversions on those specific products.

Products that are labeled as best seller ease the purchase decision among people who are never engaged with your brand. This is why one of the giant brands, Amazon, uses "#1 Best Seller" banner on its client stores.

Cross-Sell Your Products

When a visitor is viewing one of your products, you can show similar products that your customers usually buy along with the product.

This tactic is not just great for cross-selling but also a form of social proof because you are claiming that other people also purchase the product.

You can also show your popular posts in your blog to prove that these contents are very demanded because they include beneficial information.
