Google & Bing Watch Twitter & Facebook
According to WebProNews, Google and Bing are both closely watching activity on Twitter and Facebook. The more people buzz about you and your website, the better your online reputation and link popularity.
Links from prominent people (“authorities”) count more in your favor. So if you get prominent followers and visitors who are motivated to post or tweet about what you’re doing and what’s on your website, Google & Bing will notice.
