I’ve used the Facebook Like button (iframe version) correctly in the past but for some reason it’s not working for me this time. I’m sharing a webpage like http://sub.domain.com/default.aspx?foo=bar. When I view the source HTML the URL shared in the iframe correctly displays http://sub.domain.com/default.aspx?foo=bar. When I check the OG meta URL property it’s http://sub.domain.com/default.aspx?foo=bar (so far so good). When I click Like, it shares http://sub.domain.com.
Has anyone else had this issue. Like I said I’ve used this before. I can’t figure out why the others work out of the box and this one isn’t.
Do you have a <link rel=”canonical” /> tag that specifies them as the same page?
Just an educated guess – never seen the canonical links affect Open Graph Protocol sharing before.
