Old school SEO pros cover your ears, or be prepared to adapt your craft: Search engines are changing, and social media is a huge part of that change.
Bing, Google, and an increasing swath of nimble little search engines like Blekko and DuckDuckGo are incorporating social data into their results. This is potentially great news for new businesses trying to achieve visibility in search. It’s less great news for sites that rely heavily on link buying (illegal, but hard to catch), producing huge volumes of borderline-useless content (long-tail, content farm approach), or just really old domains (previously an SEO trump card).
Both Bing and Google admitted in interviews that their search results are positively affected by social signals, such as tweets, Facebook Likes, and +1s.
