How to Fix “Facebook Incorrect Thumbnail Issue” in WordPress

WordPress has made our lives much easier. However, it is not free from trouble. As you keep on working with WordPress, time and again you come across various issues such as 404 error, 403 error, memory limit error, and so on. 

One of such common yet solvable errors is the incorrect Facebook thumbnail issue. 

Many users often come across this issue and can’t find a solution. Well, look no further. Here, we have the four sure-shot ways to fix Facebook’s incorrect thumbnail issues in WordPress. We will also look into the possible causes for this issue and answer a few common questions regarding this topic. 

Let’s dive right in: 

What is the Facebook Incorrect Thumbnail Issue in WordPress?

Many WordPress themes allow social sharing, among which Facebook is the most common one. You can also use Facebook plugins for this purpose. But sometimes, as you share your article on Facebook, the thumbnail does not show up on the post or isn’t the one that you selected. You may also see a random thumbnail that does not match your post. 

This error is what we call the Facebook incorrect thumbnail issue in WordPress. There are various reasons for this issue that we will point out in the following segment. 

What Causes Facebook Incorrect Thumbnail Issue?

There may be various reasons for the Facebook incorrect thumbnail issue. The most common reason is multiple images in the same og: image tag. You see, Facebook guesses the image to put as a thumbnail for the post. It does so with the help of og (Open Graph) tags. 

So, if the image you set as the featured image is smaller than the ones that Facebook guesses, it automatically chooses the large one instead of yours. SEO plugins such as Yoast and AIO SEO automatically add the og tags on your post to prevent the thumbnail issue. We will discuss it in the solving section. 

Likewise, caching issues can also be another cause for the thumbnail issue. Other possible reasons are issues with the Content Delivery Network or missing og meta tags.

How to Fix it?

Now that you know what the Facebook thumbnail issue is and what can cause it let’s look at the possible solutions to it.

Method 1: Manually Uploading the Thumbnail Image

If you see that your Facebook post is not displaying the thumbnail correctly, you can correct it by manually uploading it. This is an easy way to fix the incorrect thumbnail image for your blog post or article.

However, this trick works only when you share your post on your Facebook page. That means, if someone tries to share that post on their timeline, the thumbnail might go back to a random or improper one again. 

Luckily, the next fix takes care of this issue as well. 

Method 2: Using Yoast Plugin 

Yoast plugin is an effective solution for solving the thumbnail issue apart from improving your website’s SEO. This plugin lets you set specific images as featured thumbnails for your Facebook posts. Here is how you do it:

  • Go to Plugins > Add New option.
