Google first suspected unclean play in May 2010. By October 2010, with Bing results started to look alike Google’s, it knew something had to be made about it – and so, in true, nerdtastic style, Google set up a sting to show that Microsoft was actually behind the general impressions of Google generated search results.
Google injected “synthetic” results into its search engine – some fake queries and results that no real user or engine would ever generate. Then, on D-Day, December 17, about 20 Google engineers were asked to run the test queries with Internet Explorer 8, Bing Bar and Suggested Sites. By December 31, some of these fake results began appearing on Bing just like Google has. See the examples after the break – it’s damning.
