Google Continues to Dominate Search

Microsoft's search share lost ground once again as competitors Google and Yahoo gained, statistics from research firm Nielsen/NetRatings indicate. Released Monday, the study showed that once again Microsoft was having trouble holding on to any gains it had made previously. In April, the company's share of the market stood at 9 percent, down 1.1 percent from the month previous.

Yahoo gained a statistically insignificant .1 percent to grow to 21.9 percent, but Google showed the most gains, with its share up 1.5 percent to 55.2 percent of all Web searches. The results are sure to cause consternation in Redmond; Microsoft has expressed disappointment with its search performance. Rounding out the top five search engines were AOL with 5.4 percent and Ask.com with 1.8 percent of the market.
