yahoo_logoYahoo just can’t catch a break. ComScore’s new U.S. search market share numbers for June will show that the company’s piece of the market has shrunk to what one analyst calls an all-time low, according to a report by Search Engine Land.

The Sunnyvale, Calif.-based company had 9.8 percent of the search market last month, which puts it in third place, behind Bing and Google. Microsoft’s search engine grew to take up 19.2 percent of the market, and picked up its gains in large part by taking share away from Yahoo.

Unsurprisingly, Google still has the biggest piece of the pie in the realm of search share, with 67.6 percent of the total market.

The search alliance between Microsoft and Yahoo has held steady at 29 percent of the total market, though it seems like Microsoft is getting the better end of the deal right now. The alliance, which was forged when Yahoo and Microsoft were headed up by Carol Bartz and Steve Ballmer, involves Yahoo using Microsoft’s algorithm and advertising products for its own search tools.

Marissa Mayer is no great fan of the deal, and said last year that she wanted to see the companies’ share of the search market grow, rather than just trade with one another.

If there’s one silver lining for Yahoo in this particular cloud, it’s that the company still has a lead of almost 4 percentage points over Microsoft in the realm of mobile search, according to StatCounter. Much like other areas of the tech industry, consumers have been shifting more and more of their time over to mobile, and Yahoo may be able to keep its lead there.
