(23,139 posts)For instance, when clicking on the DU Share button to Facebook, if the DU post has images in it, they can be served into the Meta OG:IMAGE tag which Facebook will read into the shared DU link. The result being, instead of just text or a text URL hyperlink in a box as it is now, the link is given a clickable image to go along with the URL. The meta OG:IMAGE tag can be dynamically served from the server or simply be a static DU image. Obviously, dynamic has more relevance and intrigue.
The Meta tags are fairly standard across other platforms as well, keying off the OG:IMAGE tag to automatically turn a boring meaningless URL into a rich content image link that other sites can read. It doesn't change the URL, it just make such content on the other site that much richer and dynamic.
You can test how each page will be interpreted using Facebook's URL debugging tool:

There may be an extension for this. Admins would need to source that out.
