In this knowledgebase article, we’ll discuss the error about a missing Facebook App ID “The following required properties are missing: fb:app_id” that you might have come across.
‘fb: app_ id‘ tag is used to add Facebook App ID to your website in order to use Facebook Insights. You can track visits to your page from Facebook with Facebook Insights.
It’s important to note that this issue doesn’t interfere with the ability to share posts on Facebook in any way. You can ignore this warning but it does limit your ability to use Facebook Insights data.
If you want the additional Insights data then you need to add your Facebook App ID to your website. Here are instructions below on how you can add it in WordPress using the Rank Math SEO plugin:
1 Create Facebook App
When you create a Facebook App, a unique App ID will be generated.
2 Copy Facebook App ID
In your Facebook App Dashboard, you can copy your Facebook App ID.
3 Open Social Meta Settings
Then, head over to your WordPress Dashboard > Rank Math > Titles & Meta > Social Meta as shown below:
4 Enter Facebook App ID
In the Social Meta settings, you can fill out all the fields related to Facebook, particularly, enter your Facebook App ID in the Facebook App field, so that you can get rid of the error.
5 Save Changes
Now click on Save Changes at the bottom of the page. The Facebook App ID will now be added to your website’s code and hence the error should no longer be present.
