How to share a link in Odnoklassniki and Facebook from the site?

Question

Facebook

There is a site with tests
After which the user passes the test, the image should be displayed on Facebook, Odnokalssniki, VK, Twitter if he wants to share the result.
The fact is that I optimized the page with the necessary meta tags, VK understands perfectly, but Odnoklassniki and Facebook don’t understand something.
Please help me deal with them.

Answer 1

Maybe the problem is that the domain is .photos ?
Because when I insert a link directly into Odnoklassniki, Odnoklassniki doesn't even consider it a link.
