4 What Google & Bing Say… “We treat links shared on Facebook Fan Pages the same as we treat tweeted links.” – Google, via Search Engine Land interview “Google use Twitter, Google Reader, and other sites but currently do not use Facebook. So Facebook has no real direct impact on rankings as of yet” – Barry Schwarz, SE Roundtable
5 I ran two experiments Likes used to get URLs indexed. Now they don’t.
Likes = Traffic = Links & Other Social Signals = Rankings. 6 But: Likes Do Still Impact Rankings Indirectly
What Google Say… 8 “Click +1 to publicly give something your stamp of approval. Your +1's can help friends, contacts, and others on the web find the best stuff when they search.”
“Google will study the clicks on +1 buttons as a signal that infleunces the rankings and appearance of websites in search results” - Google
Existing Google +1 Experiments 9 “+1 markings seem to have a positive effect on the number of impressions in search results because they rank higher when the same person re-visits the same search or rank higher results in the social circle of those who marked the link.
