What is og:Image? How to Automatically Generate OG Image?

Open Graph (OG) image is the thumbnail displayed on social networks (such as Facebook & LinkedIn) to preview your webpage whenever someone shares your link.

A relevant and eye-catching OG image and meta description can grab users’ attention, resulting in clicks and greater interest.

Having a solid social media marketing strategy can increase brand awareness and customer engagement, especially for medium- and large-sized businesses.

However, you must keep an eye on other aspects of your online presence too, particularly generating quality og:image - which is arguably the most important one.

Here we’ll talk more about og:images and their importance and show you how to auto-generate Open Graph images.

What is an Open Graph Image?

An Open Graph image or OG image is the image that is displayed on social media accounts when you or someone else post a link to an article or a video from your website.

By default, Open Graph meta tags determine how URLs are displayed when shared on social media sites.

You can find them in the < /head > section of a page. Tags with og: before a property name are Open Graph tags.

The following is an example of an og:image tag of a blog post:

<meta property="og:image" content="https://popupsmart.com/blog/user/pages/354.how-do-shopify-gift-cards-work/Shopify-gift-cards-cover.jpg">

And here is how the social snippet looks when linked to the article on LinkedIn:

og:Image meta tag is part of a broader set that impacts the performance of social media posts on Facebook, LinkedIn, Pinterest, and Twitter.

Posts with OG images usually receive the most attention, regardless of their impact or the quality of the linked content.

The Open Graph protocol enables any web page to become a rich object in a social graph.

Additionally, a well-designed Open Graph image makes your brand appear more professional and appealing.

When you post content that does not have an OG image, you will see a gray box or a random banner with the title and some description, like the example below:

a Twitter post with no open graph image

This reduces your chance of getting organic traffic and generating quality leads.

There is more to content than just text. Just because your article has an intriguing title or concise meta description will not make people click on it.

In fact, you might be surprised to know that around 65% of people are visual learners, and 90% of information transmitted to the brain is visual.

It is therefore vital that you use images in your content and meta tags to capture their attention.

4 Reasons Why Images Improve Your Conversion Rates

It is no secret that content is king for social media, but how do you get your users to enter your kingdom (AKA website)?

The answer is via Open Graph tags!

Open Graph Images: Why they're Important?

We all know that first impressions count. And if you're trying to get your content seen by a lot of people, then it's important to use og:image for your content.

The Open Graph meta tags, particularly og:image, give users their first impression of your blog or website.

You can think of them as digital billboards!

It's what they see when they go to your page on Facebook or any other social media adapting to Open Graph protocols, and it helps them decide whether or not they want to click through to your website or blog.

Using a relevant Open Graph image for your content can help fuel your social media engagement and boost your organic traffic.

That's why it's so important for you to use an accurate preview of the link you promote on social media—you want people to see something that will convince them that clicking through is worth their time.

How to Add Open Graph Tags Manually?

When designing and coding your website in HTML, you can use the Open Graph tags before the final < /head > tag. The meta property for an Open Graph image is og:image.

Look at the example below:

<meta property="og:image" content="https://popupsmart.com/blog/user/pages/365.free-keyword-research-tools/Free-keyword-research-tools-cover.png">

<meta property=”og:title” content=”Your Title”/>

<meta property=”og:description” content=”A full description of the page.”/>

<meta property=”og:image:width” content=”1200″/>

<meta property=”og:image:height” content=”630″/>

It would be a good idea to consider using a markup generator tool such as Ubersuggest or Search Engine Reports to reduce the possibility of syntax errors.

Just make sure to add the width and the height of your og:image so Facebook or LinkedIn can display the image more quickly.

If you use WordPress, Yoast SEO or similar plugins provide an easy way to add Open Graph tags.
