When Comscore released their May 2009 search engines rankings, Google continues to dominate search with a 65% share, followed by Yahoo at 20% and Microsoft with 8%.  Google increased its share minimally while the others lost share from April to May of 2009.  Google’s increase seems to have been carried by Youtube which experienced a 4% growth in queries. This was only overshadowed by Facebook who experienced a 5% growth.  These trends reinforce the marketing craze surrounding social media and on-line videos.

It will be interesting to see how Microsoft’s June 1 launch of Bing will affect the June rankings.
