2011 - A year for Search Marketers to remember
Every year Google makes a bunch of algorithm changes which determine the ranking order of websites. The exact number is not known, although we believe these run into the hundreds, if not thousands. Usually these changes are felt very little through the search world, with most of the changes being very subtle.
2011 was different, with around 14 changes which not only had an impact but prompted all SEOs to review their marketing strategies.
Below are the most significant changes made by Google in 2011.
