How to Fix Facebook Incorrect Thumbnail Issue in WordPress


Have you observed incorrect post thumbnails when sharing your articles on Facebook?

It’s a common issue that beginners often find frustrating. Figuring out how to get Facebook to display the correct thumbnail isn’t always straightforward.

In this article, we will guide you on how to resolve the Facebook incorrect thumbnail issue in WordPress.

Why Is Facebook Not Displaying the Correct Thumbnail Image?

There are various reasons why Facebook may not accurately show the featured image on your post. One common issue is having multiple images set in the og:Image tag, where the featured image is smaller than the other images.

Facebook utilizes Open Graph (og) tags, and many WordPress plugins, such as AIOSEO and Yoast SEO, automatically incorporate them into your WordPress website to prevent missing thumbnails.

Other potential causes include conflicts with caching plugins, Content Delivery Network (CDN) conflicts, or a missing open graph meta tag for the thumbnail image.

Identifying the precise cause can be challenging since there are no specific error messages displayed when using the debugging tool.

Selecting Your Facebook Thumbnail Using AIOSEO

An effective way to display the desired thumbnail is by using the free AIOSEO plugin. Recognized as the best WordPress SEO plugin available, AIOSEO facilitates easy content optimization for search engines and social media platforms.

Using Facebook Debug Tool to Clear the Cache

If you have added the correct thumbnail, but Facebook still does not display it accurately, the problem may be related to caching.

Firstly, ensure you clear the page cache in WordPress.

Following that, reset the cache on Facebook using their debug tool.

The Facebook debug tool is a convenient way to address Facebook thumbnail issues. Copy the URL of your WordPress post and paste it into the debugger tool.
