I just tried to share a sutta on a Facebook page and saw that the social sharing image is just a png screenshot of the website. (https://suttacentral.net/img/social_image.png) I’m guessing it was done long ago in haste and then forgotten. If you want to see the meta info that Facebook scrapes from a page, you can see it here, as an example:
Sharing Debugger - Facebook for Developers
I would suggest something like this:
It’s true that other social sharing sites use a square image, but I think this works in most situations.
It would also be great if the og:description and og:title tags could be specific to the actual page, not just generic as they are now. In fact, this error is an even bigger obstacle to sharing links on social platforms.
Sorry if this has been covered in another thread.
