Google had 65.4 percent of searches last month, down from 65.6 percent in January, Reston, Virginia-based ComScore said. Microsoft’s Bing search engine had 13.6 percent, up about a half percentage point. Yahoo! Inc.’s share was unchanged at 16.1 percent.
Google, which gets most of its sales from search-engine advertising, is trying to refine the relevance of its results after receiving complaints that some websites game its system to get more prominent placement. Google is rolling out a tool that allows users to hide all listings from sites that they dislike, find offensive or see as low quality, it said in a blog post yesterday.
Last month, Google said it changed the way it carries out Web searches to feature more “high-quality” sites, affecting 12 percent of queries.
Google, based in Mountain View, California, fell $3.59 to $576.71 on the Nasdaq Stock Market at 4 p.m. New York time. Microsoft added 27 cents to $25.68.
