uTest solicited 1,100 software developers and set them loose on the four major search engines: Google, Yahoo!, Bing, and Google's new Caffeine update. Google had the fewest number of bugs and the least severe bugs among the competition, while Bing amassed the most bugs yet still scored well in the accuracy of its results. uTest solicits bug testers with cash rewards for the quality of the bugs they discover, and pitches the service to companies as an outsourced QA department. It turned participants loose on the search engines for a week in August and only accepted bugs that were judged as new and unknown to those outside the company that developed the search engine, Cnet.
