Back in December 5, 2010, the first rumors surfaced on the social aspect of Google that is to be incorporated in searches: Google +1. This new Google initiative is said to take over what was rumored to be called "Google Me".
Yet, unlike the rumors, Google +1 is not set to kill Facebook, it's only competing with social networks' "share" buttons, the digital version of word-of-mouth and an epic weapon for viral marketing. Google +1 will certainly shake the digital world, at least from a marketing perspective, social sharing has reached a new peak by being incorporated in searches.
I was happy to hear that Google +1 will not be directly affecting SEO (awesome), the only effect it might have would be an increased traffic to certain recommended sites which will indirectly affect the rankings (very fair).
Check this video, it was posted on Google's official Youtube channel... and if you would like to test this Google service first-hand, join the experiment, I did.
