The purpose of this tutorial is to show you how to fix the Facebook Incorrect Thumbnail issue in WordPress.

In this article, we’re going to explain you why Facebook might not be showing your correct thumbnail image and how to fix this common WordPress issue.

Let’s dive in!

Why Facebook Isn’t Displaying Your WordPress Thumbnail Correctly

You’ve probably heard of Facebook’s Open Graph tags. Introduced in 2010, Open Graph tags are like digital name tags that help Facebook interact with your web pages. They allow posts from your website to become rich, interactive objects on Facebook’s platform, equipping them with the same features and functionalities as native Facebook posts.

The og:image tag plays a crucial role here. Facebook uses these tags to decide which image should be displayed when you share a post. So, if there’s an issue with your WordPress thumbnails on Facebook, it’s likely stemming from your Open Graph tags.

For example, you might have multiple images set up in the og:image tag and your feature image is smaller than the others.

Or you might not have any og:images and Facebook might not be able to retrieve your thumbnail image.
