A new study conducted by the AT Internet Institute claims that Bing is now the second most popular search engine in the UK, passing Yahoo.

The study accounted for more than 12,696 websites across Europe. In the UK, Yahoo fell 0.5 percent from February 2010 to March 2010, while Bing remained consistent month-over-month, indicating that Yahoo lost ground to less popular search engines. Google is still the dominant search engine in the country, taking up 89.7 percent of the country’s searches. Bing and Yahoo account for 3.8 and 3.6 percent of the searches, respectively.

Bing was also consistent in Germany and Spain, while it lost market share in France. As is the case with the UK, Google is the dominant search engine in those countries, taking more than 89 percent of the searches in all three countries.

Microsoft launched the Bing search engine last year. Though it has been trending up since its launch, Bing still has a lot of ground to cover before it makes any significant impact on the search engine optimization (SEO) landscape.

Bing did help Microsoft drive ad growth in 2009, though. The company reported that the search engine was responsible for a 19 percent increase in ad revenue.
