Facebook is showing the wrong image, title or description

How Facebook Reads & Stores Information

Facebook has cache for information that will appear inside the share dialog when someone share a page from your site. Once the information is set in the cache the changes you put on site will appear after a few days (not immediately).

To provides a tool Facebook Debugger that can be used to refresh the cache. You can read more about usage of that tool here.

Still don’t see your updates?

If you still don’t see the appropriate information, there are a few steps you can take:

• Go to Facebook and view the post where you shared your article. Click the small arrow in the upper right corner and select Refresh share attachment. This will tell Facebook to discard the current information and update it to match your Open Graph tags.
• Clear out any site caching plugins (example: WP Super Cache, W3 Total Cache, WP Rocket, Comment Cache, SG Cacher), optimization plugins (example: Autoptimize), CDNs, Cloudflare, etc. to make sure the bots aren’t getting a cached version of your URL.
• Make sure you saved the content after you edited.
• Check your warnings and errors in the Facebook debugger – may be the image may not meet Facebook minimal requirements. Click here to start Facebook Open Graph Debugger or visit this article to understand how to use it.
• Is your site publicly accessible? If you’re using a “coming soon” plugin or maintenance mode is active, Facebook won’t be able to see your page. If you are using a member limited private content than Facebook may also not see that too.
• Are you using a different plugin that already generate such social share optimization tags? Most of SEO plugins also does that and changes you do may not appear if Facebook is referring to a different instance of tags from site. If you are using Yoast SEO plugin you can find a tutorial how to deactivate generation of the extra tags here.
