Are there any best practices for offering like buttons within canvas applications? We've got an app which has lots of content, when I specify the OG:URL of some piece of content as a page within apps.facebook.com/myapp, the "like" share shows up as pointing at apps.facebook.com. Is this the best way to do this, or how are other people handling this? Thanks!
The OG tags for my content look roughly something like this:
<meta property="og:title" content="some cool title" />
<meta property="og:image" content="some cool image"/>
<meta property="og:site_name" content="my site name" />
<meta property="fb:admins" content="my id" />
<meta property="og:description" content="Hey neat wow this is content."/>
<meta property="og:url" content="http://apps.facebook.com/myapp/somecontent.aspx">
<meta property="fb:app_id" content="my_appid" />
