While Google still had 67% of the market in May, this dropped to 62.7% in June 2007. Microsoft's MSN on the other hand saw an increase from 8.4% to 13.2%.
Yahoo's marketshare remained pretty stable, with only a very small 0.1% drop from 19.7% in May to 19.6% in June.
Google finally has a competitor join it in the (until now) exclusive, positive-year-over-year-growth club. MSN/Live increased their query volume by 67% from May, and 48% from a year ago. Search volume was up all across the board in June and took most everyone else in the same direction.More info at Compete.
A good portion of the additional Live searches are coming from the Live Search Club, where you can apparently play games for points which you can redeem for fine Microsoft products. All of the games involve using Live’s search engine - to get the points, you have to search with Live. It looks like Chicktionary is leading the charge (by the way, “chicktionary”… not as cool as it sounds).
We didn’t see any traffic to club.live.com at all in April. About a third of a million unique visitors went to the club in May, and in June, this shot up to over 3 million unique visitors.
