Google absolutely dominates over Bing, Yahoo, AOL, Ask, or any other third tier search engine. Google accounts for approximately 94% of all search engine traffic to our network of sites. Yahoo came in second with 4% of traffic, with Bing bringing up the rear at 1.5% What was interesting was that image-heavy sites like PandamicPhoto.com or AntiMatterStudio.com benefit strongly from Bing's image search engine. Bing sent more image search results to our sites than any other search engine. It is our belief that Bing has a superior image search interface and algorithm. While Bing's presence in our web stats is currently diminutive, we feel Bing has a lot of potential. For this reason, we've recently revised our SEO efforts to better target natural marketing on Bing.
