Why are Facebook Thumbnails Not Showing When Sharing Link

Facebook thumbnails play a good role in the development of your site, capturing the interest of potential visitors and bringing them to your site ‌boosting your site’s engagements.

There are many reasons ‌your Facebook isn’t properly displaying your post’s featured image when you share the post on the platform.

One reason you are experiencing the Facebook incorrect thumbnail issue is that you have multiple images in your tag og: image, and the other images set in the tag are larger than your feature image.

Facebook uses snippets of codes called Open Graph (og) meta tag. Og tags control how URLs shared on social media are displayed. Plugins like Yoast SEO and RankMath automatically add this tag to images uploaded on your site to prevent the missing thumbnail issue.

Other causes of the Facebook incorrect thumbnail include missing open graph meta tag, conflicting caching plugins, CDN issues, etc. It’s challenging to figure out the main reason behind the issue as no specific error message is displayed when using the debugging tool.

Let’s move now to how to fix Facebook’s incorrect thumbnail issue.
