According to comScore, Bing captured 10.7% of all search queries in December, up from 8% last May. Meanwhile, Yahoo lost about as much as Bing gained over the same time period to end up at 17%. Google remained relatively flat at 65%.
If this trend continues at the same rate, Bing will pass Yahoo to become the #2 search engine, in terms of query traffic, by August.
Our own TrafficEstimate.com (TE) traffic reflects the positive trend for Bing. But the overall breakdown of traffic by search engine is much more heavily skewed towards Google, where it has a commanding 95% of TE’s search traffic. I am always mystified, on how reporting agencies, like comScore, do not reflect what most website owners see for search traffic market share. I rarely see sites where Google makes up less than 80% of their search engine traffic.
That being said, you still have to appreciate the gains that Bing is making on both Yahoo & Google.
