Google accuses Microsoft of copying search results-
Google accused Microsoft of copying its search results after conducting a “sting operation,” which found that Internet Explorer is tracking user behavior and Microsoft uses that data to tweak Bing’s results. Google fed the story to Danny Sullivan of Search Engine Land. In Sullivan’s post 
Google’s Amit Singhal explained, “I’ve spent my career in pursuit of a good search engine. I’ve got no problem with a competitor developing an innovative algorithm. But copying is not innovation, in my book.”
Initially, Bing did not explicitly deny Google’s claim. Stefan Weitz, director of Microsoft’s Bing, explained to Sullivan, “As you might imagine, we use multiple signals and approaches when we think about ranking, but like the rest of the players in this industry, we’re not going to go deep and detailed in how we do it. Clearly, the overarching goal is to do a better job determining the intent of the search, so we can guess at the best and most relevant answer to a given query. Opt-in programs like the [Bing] toolbar help us with clickstream data, one of many input signals we and other search engines use to help rank sites. This “Google experiment” seems like a hack to confuse and manipulate some of these signals.”
