It’s only one week, but Microsoft (NSDQ: MSFT) can claim some new traction in the search market, courtesy of its Bing search engine relaunch, according to comScore (NSDQ: SCOR). Of course, it could just as likely be that it’s because it’s one week in that the Bing numbers look good, considering that many people are likely just trying out the search engine.

comScore says that both Microsoft’s “average daily penetration among U.S. searchers” and its “share of search result pages in the U.S.” showed substantial improvements. Says comScore senior vice president Mike Hurt: “So far it appears that the lifts in searcher penetration and engagement have held relatively steady throughout the five-day period. The ultimate performance of Bing depends on the extent to which it generates more trial through its extensive launch campaign and whether it retains those trial users. It appears it is off to a good start.”
