Social signals

One of the things that SEOs have been predicting over the past couple of years is the influence of social media on search engine rankings. 

In the 2011 chart above, page level social metrics is shown to be significant, and the questions SEOs have been asking is what social signals the search engines are looking for, and how influential they are. 

The report does find a correlation between sites with strong social metrics and those with higher rankings. The most significant factors here were Facebook shares, comments, likes, followed by tweets. 

The future of search

The 134 SEOs were also asked about the future of search, and how ranking factors would change over the next few years. 

Most predicted that the analysis of a page or website' perceived value to users would become more important, followed by social signals at both page and domain level.

Hmmm, interesting. Its funny to see that anchor text for external links is deemed not to be a priority factor, even though theres still so much noise in the industry that this is major focus.... The rest is good. It shows that I'm focusing on the right things!

Sheldon Cooper sums this up perfectly -- it's common sense (though I've never typed the work 'bazinga').
