Facebook pushes search further ahead - has "Like" replaced the "Link"???
To all the SEO heads out there this now poses the question what is Facebook SEO and what is possible via the Open Graph. What is clear now though is this marks the start of the beginning of Facebook's internet strategy.
At the technical level interesting questions that pop to mind are given that all of the OGP metadata is basically RDFa - theycould index the same info if it supported the OGP schema/namespace. The good news is FB is open to changing the OGP spec to better support the standardised version of RDFa http://groups.google.com/group/open-graph-protocol/browse_thread/thread/cc03368ef0d12c1a
As one commentator I read in a forum highlighted " What we really need is for Google Snippets to better support RDFa and also a standardised version. As does Yahoo (Search Monkey) Twitter (Annotations/Search) and eventually Bing. That way every website can add in a standard set of RDFa metadata to create semantic search engines which also creates better SEO for every website. My big fear right now is that each company will split RDFa efforts (now part of HTML5) and create their own namespaces."
It's got very interesting all of a sudden. What a day! I wonder what else is to come... it's hard to keep up with it all!!! :)
