Microsoft Bing busted Yahoo's bubble in August, pulling ahead of its search-providing partner 13.9 percent to 13.1 percent. Combined, the companies sport 27 percent market share, Nielsen said. Google holds 65 percent.
The combination of Microsoft's MSN,
Windows Live and Bing search properties helped Microsoft overtake Yahoo in
search for the first time ever in August, according to researcher Nielsen.
Microsoft's properties tallied 13.9 percent of search volume last month,
compared with 13.1 percent for Yahoo, which fell from 14.3 percent share in July. Nielsen provided this line graph
of the search figures.
Why the decline? Yahoo is letting Bing power its search results under a 10-year search deal
August 24 in the U.S.
That means Yahoo lost a whole week of searches to Bing.
Combined, Microsoft and Yahoo hold a 27 percent share of the search market
versus Google, which retained its dominant share of the U.S. search market with
65 percent, Nielsen said.
HitWise said last week that Bing and Yahoo combined
for nearly 25 percent of U.S.
search queries through their first full week of integration.
When Nielsen reflected on the past year in search volume, Google has seen
little change in search share, while Yahoo has dipped from 16.0 percent in
August 2009 to 13.1 percent today. Conversely, MSN/Windows
Live/Bing's share has grown from 10.7 percent in August 2009 to its current13.9
It could be that a portion of Yahoo users lost confidence in the company
after the search deal was announced July 29, 2009, and switched to Bing, which
saw its uptick begin in August 2009.
Things aren't going to get easier for Bing or Yahoo. Google kicked up
the pressure on both search engines last week, with
the launch of Google Instant, its predictive search technology for letting
users find information without typing in complete queries.
The market now awaits comScore numbers for the search-engine market.
The company recently reworked
its metrics for counting search queries, taking
into account explicit core search-excluding contextual clicks on slideshows-and
total core search, which counts total numbers.
