Hitwise reports that Google’s market share for May is 65.13%. While fielding nearly two thirds of all US searches is definitely not a bad thing, Google’s market share didn’t grow over April 2007. In fact, it actually declined 0.13 percentage points. While the amount is minuscule (representing 0.2% of their market share), for the first time in recent months, some of the other major search engines actually gained market share.
Yahoo was up 0.16 percentage points, or 0.8% of their April market share. MSN/Live, like Google, was down, but only 0.06 percentage points (albeit far less than their previous month‘s loss of 0.69 percentage points).
