Another month, another report that Bing is chiming slightly louder. Analytics firm comScore has just released its latest figures on search market share, and once again Microsoft's search engine has managed to grow while its competitors have seen modest losses.
Bing launched to the public on May 31, when Microsoft held 8.0% search marketshare. Over the course of June and July, the site has gained nearly a full percentage point — it's up to 8.9%, and growth was actually higher for July than for June, when the site was getting all of its launch attention. Of course, Bing's marketshare still pales in comparison to Google's dominant 64.7%, but at least Microsoft is heading in the right direction.
Once again, it looks like Bing's gain comes at Yahoo's expense, at least to some extent. Since May, Yahoo has dropped from 20.1% to 19.3%. Google has dropped a more modest .3%, from 65% to 64.7%. We saw a similar pattern last month, when we pointed out that Yahoo was losing marketshare both from below (Bing) and above (Google).
Since then though, the landscape has changed dramatically: Yahoo search will soon be powered by Bing. When the Yahoo/Microsoft search deal was announced Yahoo EVP Hillary Schneider discounted the impact of this market share erosion, stating, "seeing Bing as a live experience was a nice assurance but did not change our rationale or timing." But it's hard to believe that Bing's strong start didn't have an impact on the deal.
Once that deal comes to fruition Bing will have to face the real test: can it continue to take market share away from Google, or will it simply continue to eat away at itself as users move from Yahoo's portal to the Bing homepage?
