Online marketing landscape and how social, paid and organic search are evolving and impacting each other. Is the 'free' SEO marketing being downgraded by Google?
"Google Social Search is a new tool that Google created to allow its users to display results in the SERPs based on what their social connections think or comment on.
So to put it simply, if you log in to your Google account, link it to your other social media accounts (Twitter, Facebook, Google +) and do a search on something that your friends have been talking about online, then the results you see on Google will be influenced by their opinions.
Social Search is the latest development from Google’s experiments with social media in its quest to compete with heavyweights like Facebook and Twitter. It ties in well with Google + and the +1 button, Google’s equivalent of a social network and “Like” buttons.
The impact of Social Search on natural listings and SEO is clear with users being able to almost control what results they get".
