Hello,
I apologize for the issue you are facing when trying to share your blog post on LinkedIn. To address the error message "Cannot display preview. You can post as is, or try another link," there are a few steps you can take:
-
Check Open Graph Tags: Ensure that the Open Graph tags are correctly set up for your blog post. These tags help platforms like LinkedIn display the correct preview information. You can set the default Open Graph image using Rank Math by following these steps: Set the Default Open Graph Image Using Rank Math.
-
Verify URL Format: Make sure that the URL you are sharing includes http:// or `https://rankmath.com/wp-content/uploads/2022/06/image-1.png the beginning. Some platforms, including LinkedIn, require this for generating link previews.
-
LinkedIn Cache: Sometimes, LinkedIn may cache old information about a URL. You can try clearing the LinkedIn cache for the specific URL using the LinkedIn Post Inspector.
If after checking these steps you still encounter the issue, please reply to this ticket, and a human agent from our support team will assist you further.
Thank you for reaching out to us with your concern. We are here to help you with any further assistance you may need.
Best regards.

Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
We checked the page you’ve shared with the LinkedIn Post Inspector and we can see the og image is showing there properly without any issues:

However, the image you’re currently using is 801 x 861 pixels in size.
Please note that the recommended image size is 1200 x 630 pixels. If the image’s dimension is too small or too large compared to the recommended image size, then the individual social networks may not read your image correctly.
Also, it looks like you’re currently using the Rank Math PRO plugin on your website, but the account you have used to open this ticket is the Rank Math free version.
Please search and forward a receipt from FastSpring.com so we can locate your account and verify it.
Looking forward to helping you.
Thank you.
