Have you ever shared a link to your latest blog post on Facebook then you notice that the image isn’t the one you intended? Instead of Facebook pulling up the featured image, it shows another picture that was also in the blog post.
Then you deleted the Facebook post and tried to reshare the link again only to end up with the same problem.
We feel your frustration. The problem could have been that the picture you used as the featured image of the blog post didn’t meet the minimum size requirements set by Facebook so the algorithm opted for another pic.
If you used the Facebook debugger, you could have identified this issue before sharing the link to the blog post and fixed it immediately.
In this article, you are going to learn how to use the Facebook debugger to avoid any mistakes and share fantastic Facebook posts.
What is a Facebook debugger?
The Facebook debugger tool allows you to see the information Facebook pulls out of a URL such as a link from your site. These pieces of information include the post title, the featured image, and the post description. It is possible that Facebook may pull the wrong information from an article. So the debugger helps you identify the errors and make necessary changes so that the post appears as fantastic as you wanted.
You don’t want the wrong image appearing on a Facebook post when you share a link to an article because Facebook failed to scrape the featured image. Your post will have low engagement rates and few users will visit your website because it doesn’t resonate with their needs.
But with the Facebook debugger, you will avoid such mistakes because the tool enables you to check if everything is right before sharing your blog post on your Facebook Page or Profile. So you will fix any errors found before the Facebook post goes live.
What are Facebook Open Graphs?
Open Graph is an internet protocol that enables the use of metadata to represent the contents of a web page. It was introduced by Facebook in 2010 to enable its users to share links from their websites.
So the metadata includes the page title, the featured image, and the page description. Look at this Facebook post where we shared the link to our latest blog post:

Uniclix Facebook Page
All the features present on this Facebook post make up the meta tags or open graph tags that the Open Graph algorithm scraped from the original article — the page title, the page description, and the featured image.
It is these meta tags that sometimes may not come out as you wanted. For example, the image may not be the right one and the text may not be what you intended. The Facebook debugger enables you to identify these errors before you share the post then you correct what is necessary to make the post as engaging as you wanted.
If Facebook fails to display the right text or image, it means that the Open Graph algorithm failed to scrape the correct metadata from the page. And you end up with a funny-looking Facebook post.
How to use the Facebook debugger
Facebook debugger is easy to use. Even better, it is free! All you need to do is visit the debugger website and paste the URL of the page you want to share and press the “debug” button.
Let me show you the step by step process on how to use the Facebook debugger.
Step 1: Visit the debugger website by clicking this link.

Step 3: Press the “Debug” button on the right to analyze the contents of the link you want to share on Facebook.
If certain meta tags are missing, the Debugger will show them as warnings. The Debugger will also provide information showing the previous time Facebook scraped your page or website.

Apart from the warnings about the issues that need to be fixed, the Debugger will also show you how the Facebook post will appear when you share the link.

The blog posts debugger also shows you how the Open Graph algorithm reads your URL. There are many meta tags that the debugger provides in the preview process. It is your duty to go through all of the meta tags to ensure that the right information comes out when you share the link.

If there are any mistakes in the link preview, you will notice them before your audience. Correct those errors to improve engagement rates and connect with your audience at a deeper level. When your followers notice any errors on your Facebook post, they are less likely to interact with it and gradually lose interest in your entire brand.
Step 4: Clear the caches
If the Facebook preview doesn’t show up the way you wanted, then you should begin by clearing the caches. The preview may be defaulting to an older version because your Facebook or WordPress has an outdated version.
If your page is built on WordPress, then should clear all the caches. To do this, visit your WordPress admin dashboard and got to Settings. Locate the WP Super Cache. Press “the delete cache” button located under the Delete Cached pages section.
To clear the Facebook cache, click on the button, “Scrape Again” found at the top of the debugging report.
If after doing these two things the preview is still isn’t right, then move to the step.
Step 5: Change the Open Graph Settings
If after clearing the WordPress and Facebook cache your preview still isn’t as you want, then you may need to scroll down the report to learn more about your issues.
This lower end of the debugger report contains all the issues that the Open Graph algorithm encountered when pulling information from your page. Your team can study the report to identify the source of the problem and correct it before sharing the page with your audience.

You certainly have issues with your open graph tags when the preview still has errors even after clearing the WordPress and Facebook caches.
Once you have fixed the issues your team identified when studying the debugger report, run the debugging tool once again and check the preview.
I hope that this time it would come out as you want with the right text and images.

FAQ Section on Facebook Debugger
Why doesn’t Facebook share my posts correctly?
These are the reasons why your blog posts may not appear as meticulously as you wanted when you share them on Facebook:
1. Incorrect image sizing
Facebook has sizing requirements for every content you intend to share on the platform. If the image you used as a featured image of your blog post doesn’t meet these requirements, then the Open Graph algorithm will find another image within the post that meets the guidelines and use it as the right image.
2. WordPress caches
WordPress caches may confuse the Facebook algorithm pulling information from your site on which page to use. You can install a WordPress caching plug in to keep your pages loading fast and still not confuse the Facebook algorithm on which metadata to pick.
3. Facebook Caches
Have you ever deleted an image in a blog post and replaced it with another one but when your repost the link on Facebook, the old image still appears? Now that is due to Facebook caching.
4. Missing featured image
If your blog post has no featured image, then the algorithm is likely to pull up another image to act as the featured image. To solve this problem, ensure that every blog post you are sharing on Facebook has a featured image uploaded on WordPress.
