Microsoft Corp.’s Bing has beaten Google Inc. to the punch.

Google has been rumored to be casting an eye toward creating a tool for searching social networking sites, like Twitter. But today, Bing came out and did it.

When someone does a search on Bing for Al Gore in association with Twitter, for instance, the user should see Gore’s latest tweets come up among the search results.

If online chatter succeeds, Bing won’t be alone for long in offering this Twitter-search feature.

A possible Google microblogging search service that would focus on finding Twitter posts has been the subject of online chatter in recent weeks.

The truth, though, is that the change is not nearly as dramatic as it appears at a glance. While Bing has, according to certain data, minimally increased Microsoft’s search market share, Google’s position has not significantly shifted.

Bing vs. Google: The Buzz

All the buzz comes from a new search market analysis by Web stats company StatCounter. Bing, the researchers say, secured 8.23 percent of all U.S.-based searches for the month of June. (Bing officially launched on June 3.) The previous month, StatCounter shows Microsoft sitting at 7.81 percent of U.S. searches. That amounts to a month-to-month increase of just under half a percentage point following Bing’s debut.

Google, during that same time span, dropped from 78.72 percent to 78.48 of U.S. searches — a decrease of 0.24 percent, according to StatCounter’s data. Looking back to April, the difference becomes slightly less apt to be obliterated by a sneeze: Google’s two-month drop amounts to 0.59 percent, while Microsoft’s April-to-June gain comes out to 1.02 percent.
