According to this update... https://developers.facebook.com/blog/post/2013/06/19/platform-updates--new-open-graph-tags-for-media-publishers-and-more/
...I thought article:publisher (with page ID or URL) would put a like button for the representative page when shared links are posted to walls? The debugger seems to think differently... what am I missing?
Debugger info:
Object at URL 'http:// domain.com/post/' of type 'article' is invalid because the given value 'http:// www.facebook.com/mypage' for property 'article:publisher' could not be parsed as type 'profile'
article:publisher is for Facebook pages, article:author is for individuals.
The "Follow" and "Like" buttons will only appear for people who haven't already followed the author or liked the publisher page.
