Using the Facebook Debugger

Sharing Debugger lets you preview how your content will look when it's shared to Facebook and debug any issues you may find.

To use the Facebook debugger: https://developers.facebook.com/tools/debug/

1. Click here.

2. Enter your site's URL in the URL field.

3. Click Debug.

4. Click either:

   • Fetch new information for URLs that have never been shared on Facebook before.

   • Scrape Again for URLs that have been shared on Facebook before.

After debugging, Facebook displays the information that was "fetched" and what is displayed when the link is shared. Scroll down to Link Preview to see what will be shared.

Important:

• If you've debugged your site and it's still displaying the outdated info, try clicking the Scrape Again button. You may need to click this a few times before you'll see the information updated.

• If debugging does not resolve the issue, please make sure that you have added your personal Facebook Account username (not your Business page username) under the Social Settings.

• Make sure that the thumbnail follows Facebook's recommendations in terms of size and resolution. For more information, click here.

• In some cases, there may be an issue on Facebook's end and the debugger does not correct the information.
