Google Now Use Twitter, Facebook and site speed to rank your website

Google originally made its name by using a Page rank system based on links throughout the web to return relevant search results to users.Although there were many search engines available before Google the page rank system simply returned better results to users.Page Rank (Googles Internal Page Rank Not So Much Toolbar Page Rank, a long story) is still the major factor in how search results are delivered and things like Back links and anchor text are still the major players and always will be.However over the years Google have added lots of other factors in how they return their search results, they claim there is over 200 components used to deliver the results we see.A couple of noticeable more recent additions to this are Social Media and Site Speed.
