A new study by online ad network Chitika shows that an individual Bing user is worth one and a half individual Google users in value to website owners. The company compared ad click behavior on Google and Bing and found that Bing generated about 50% more clicks: "Across the sample of nearly 15 million impressions used for this study, Google users clicked on ads at a rate of 1.09%, while Bing users clicked on ads 1.67% of the time."

"Bing's Cashback service did its job, and ensured that people who were using search with a clear intent to buy came to Bing," says Alden DoRosario, Chitika's co-founder and CTO.
