As a follow up to a post here on Friday about an apparent turn in December U.S. search market share (according to Nielsen Online, Google’s share was down and Microsoft’s was up) check out the work Kip Kniskern of LiveSide.net has done comparing a full year’s worth of data from three major market-share tracking companies.
He’s got some nice charts and graphs, depicting the differences in search market share numbers for Google, Yahoo, MSN/Live Search and Ask.com as reported by Nielsen, Hitwise and Compete. Nielsen, Kniskern found, reported a bump in Microsoft’s share starting in May 2007 that the other two missed. In general, Yahoo’s share has been trending down, but the decline is less pronounced in Hitwise’s figures.
“Really, if anything, the numbers for each of the [search engines] could be said to have remained fairly flat in their share of searches over the past year,” Kniskern wrote.
