How to Fix Post Display on Facebook Using Facebook Debugger

Today, Facebook has become a popular social networking channel. It is estimated that billions of posts are posted every minute on this channel. Surely you've also shared a post on the website (share link) on Facebook. However, Facebook doesn't always display the right information about that post. Sometimes it displays the wrong information or shows missing avatar, title, description, ... It's annoying when your blog or website is a similar case. To fix post display on Facebook, Facebook has a tool called Debugger that helps you check the errors as well as force Facebook to update new information from the link you want.

However, before learning how to use this tool, let's see why you encounter errors like the above.

Why Do Errors Happen When You Share Posts on Facebook?

Whenever someone shares a post on Facebook, Facebook scans and saves the basic information about the image, URL, title, description, and even meta tags of that post.

Firstly, if the post's data does not follow Facebook's criteria, your post will display with some missing things. On the other hand, if the meta tags contain the wrong information, the post will display incorrectly as well.

Secondly, this information will be cached by Facebook for 30 days. So, if you change the post information, it will not show the new information until the cache expires. Your post is going to display properly when Facebook scrape the link once again.

Facebook Debugger helps you to fix both the two above causes by finding the errors, clear Facebook’s cache, and force Facebook to update the information.

Fix the Errors of Post Displays on Facebook

When posts have errors about displaying on Facebook, we often have to do one or all of the following:

  1. Check and update meta tags on your website;
  2. Clear the cache on your website;
  3. Force Facebook Debugger to update the post information.

If your post has been updated and the previous posts have no problems in displaying, you only need to do the 3rd step. In other cases, you should perform all three.

Clearing the cache will ensure that Facebook will not crawl the old version of your website’s information.

If you are using the WordPress plugin for saving the cache, you will have options to clear the cache as well.

Using popular plugins like W3 Total Cache or WP Super Cache, you just need to go to the dashboard of these plugins in the admin section of WordPress, choose to delete the entire website cache.

It only takes a few seconds for Facebook to scan and record the new information. After that, you can re-check if the displayed content and meta tags of the post have been updated or not. At this step, everything may be right. Otherwise, come back from the step of editing meta tags.


To make sure that your post will display correctly and beautifully, you should pay attention to some additional points as follows:

  • Use photos with the right size: Photos must have a ratio of 1.91:1 or 1:1. To make the image appear sharper and more beautiful, you should choose one having either width or height is more than 500 px.
  • The title displays fully when it is less than 25 characters. In some cases, if the title is longer, it may not show all the text.
  • The post description will also display most fully when there are less than 30 characters. Similar to the title, it may be partially hidden if you write longer.

Don't use Facebook Debugger only when you see an error. You should regularly use it to ensure that the post always displays perfectly on Facebook.
