I am attempting to integrate Facebook open graph into my site but I ran it through the URL Linter and I get the error: "Required Property Missing, og:titleand og:url is required". This is a description page for my product.

Am I missing something?

I believe the problem arises because your og:url points to an app page (yours, I assume).

The Facebook code for the Like button will, as far as I know, go to that URL and attempt to retrieve the metadata from there - not from the original page that you posted here.

So the error message is telling you that your app page within Facebook doesn't have these metadata elements.

I have explained in more detail the use of og:url.
