Bing is giving much more preference for its SERP ,If you take a close look this days for Bing optimization you have to make links from social networks like Facebook, Twitter and Blogs rather than website links.If you can make some links from Facebook like button page that will be countable in a good manner. Bing search engine specially like the links from your friends and your social networks group those who speaks about you and your website.Apart from that After a collaboration between Facebook and Bing , those online giants trying to dominate Google’s SERP algorithm by introducing this special pattern.Also with this marge Bing is integrated the Facebook database for SERP algorithm.So its time to change the SEM strategy for SEO.
I highly doubt this because if it were true, nearly all websites would be in greater competition with each other considering the fact that nearly all of them have a specific page on Facebook
The fact of the matter is - it works only if you're logged in to your Facebook account. Also, it'll show the "like" results only from your friends on Facebook. Its a similar thing on Google. When you're logged in to Google, it saves your search preferences and prioritizes the sites of your interest and your visit history. Bing is just leveraging advantage of millions of registered users on Facebook connected together.
