Hello,
Thank you for contacting Rank Math and sorry for any inconvenience caused.
Make sure your image file size is under 300kb.
If you are using minification on your website and your cache plugin is inputting too much inline CSS into your page source that your OpenGraph tags are pushed way too down your page’s source.
If this is the case, you must move your inline CSS to a file because Facebook and other social networks will only look for OpenGraph tags in the first 60kbs of your page’s source. If they don’t find it, they will assume you haven’t added them. They don’t want to waste their resources crawling huge pages looking for OpenGraph tags.
Once you are done, you might want to test again here:

I hope this helps. Looking forward to helping you.
Hi Anas, thanks for your response! How do you “move your inline CSS to a file”?
Thanks
Hello,
You would need to take inline CSS and add it to your theme. For example, by adding a new CSS file to your theme with that content, you can get in touch with your theme provider for this.
If the inline CSS is likely coming from your optimization plugin.
Please temporarily deactivate any optimization plugins that you may have recently installed and then check if there will be any change in this.
Let us know how this goes. Thank you.
