Once we have discussed that social media has value in SEO but there was no clarity on the role of Facebook, twitter, Pinterest etc. for ranking purpose.
This time again I am asking what is the importance of Social Shares and hope you experts have some solid proofs now. Today first time I saw Facebook in Google Webmaster report links to your site, (screenshot below) Pinterest was there already for some time. It means now Google is accepting the value of competitor as SEO factor. Is there any such announcement from Google? Please enlighten!?
