The December 2007 figures from Nielsen//NetRatings show the US search market share for Google declined from the previous month.

You could knock us over with a feather. Though the various measurement services that report on search market share - NetRatings, Hitwise, Compete, and comScore - all show slightly different percentages for each search engine, Google doesn't go backwards often.

It did in December 2007, according to NetRatings. In November 2007, Google held 57.7 percent of the search market, as they handled nearly 4.3 billion queries.

In December, Google's nearly 4.1 billion queries occupied only 56.3 percent of search. Yahoo saw a smaller search drop, from 17.9 percent (1.3 billion queries) in November to 17.7 percent (1.27 billion queries).

Microsoft's MSN and Live Search brought in 996 million queries in December, good enough for 13.8 percent in December. These represented a gain from 881 million November queries (12 percent.)
