Have you noticed incorrect post thumbnails when you share your articles on Facebook?
It’s a common error that beginners often complain about. It’s not always clear how to get Facebook to display the right thumbnail.
In this article, we’ll show you how to fix the Facebook incorrect thumbnail issue in WordPress.
Why Facebook Is not Picking Up the Thumbnail Image
There are many reasons why Facebook might not correctly display the feature image on your post. One of the most common reasons is having multiple images set in the
og:Image tag where your featured image is smaller than the other images.
Facebook uses Open Graph (og) tags, and many WordPress plugins like AIOSEO and Yoast SEO automatically add them to your WordPress website to prevent missing thumbnails.
Among other causes are caching plugins, CDN conflicts, or a missing open graph meta tag for the thumbnail image.
It’s really hard to guess what’s causing the issue because there are no specific error messages displayed when using the debugging tool.
