Facebook Social images not showing when using CDN

Hello,

We apologize for the issue you are facing with Facebook not displaying your social images after switching to a CDN. Here are some steps you can take to resolve this issue:

1. Check Open Graph Tags: Ensure that the Open Graph tags are correctly set up on your pages. You can verify this by using the Facebook Sharing Debugger. This tool will show you what Facebook sees when it tries to scrape your page.

2. Image Accessibility: Make sure that the images hosted on your CDN are publicly accessible. If the images are restricted or require authentication, Facebook will not be able to access them.

3. Image Format and Dimensions: Confirm that the images meet Facebook’s requirements. The recommended image size is 1200px X 630px, and supported formats include JPEG, PNG, GIF, WebP, and AVIF. If your images do not meet these criteria, they may not display correctly.

4. Cache and Minification: If you are using caching or minification plugins, ensure that they are not interfering with the loading of your Open Graph tags. Sometimes, these plugins can push the Open Graph tags down in the source code, making them inaccessible to Facebook’s crawler. You may need to adjust your settings or clear your cache.

5. Gzip Compression: If you have gzip compression enabled in your caching plugin, try disabling it. This setting can sometimes conflict with Facebook’s ability to read Open Graph tags.

6. Scrape Again: After making any changes, go back to the Facebook Sharing Debugger and click on the Scrape Again button to refresh Facebook’s cache of your page.

If you’ve gone through these steps and the issue persists, please reply to this ticket, and a human agent from the Rank Math Support team will assist you further.

Thank you for raising this concern!
