Bing Still Has Zing, Google More Bling–But Yahoo No-Thing

According to the latest data from comScore, which are the most widely regarded by Wall Street, Bing has not lost search market share in the U.S., as some recent reports had suggested.

The September qSearch report, which was released to clients today, shows the Microsoft (MSFT) search service with a 9.4 percent share, compared to 9.3 percent a month earlier.

Dominant search giant Google (GOOG) also saw a slight uptick to almost 65 percent. Yahoo (YHOO), which just began a $100 million marketing campaign, saw share drop a half-point to just under 19 percent.

Both the market shares of Ask and AOL remained constant at almost four percent and three percent, respectively.

The comScore (SCOR) data on Bing counter two earlier reports that showed declines.

Here is J.P. Morgan analyst Imran Khan on the new data, as well as a table from comScore (click on it to make it larger):
