Is Bing more biased than Google when it comes to the results pages? In research that has been gaining traction as of late, the answer seems to be yes. It wasn’t a directed study on a few select terms either, it was a large random sampling of the SERPs conducted by a professor at George Mason University.
What he found in the tests that he conducted was that for the most part, Bing will favor Microsoft content more often and more prominently, than Google favors its own content. According to the findings, Google references its own content in its first results position in just 6.7% of queries, while Bing provides search result links to Microsoft content more than twice as often (14.3%). The percentages may seem small, but when you consider there are billions of searches performed daily, suddenly 14% isn’t such a small number.
The findings also cast a different light on the recent FTC antitrust complaints which Google has been handling surrounding anti-competitive behaviour. It’s also a stark contrast to a similar study done earlier in the year, which concluded that “Google intentionally places its results first.” So now as a user with two completely different data points, which is the set to believe?
Well the second study which has been conducted had two goals in mind : To replicate the findings of the first study and to also expand on the methods used to determine if it was perhaps an issue in how the results came about. From the very beginning, it was found that while Google does favor its own content at some points, the selection of terms is exceedingly small. What was also learned and wasn’t mentioned in the first study, Bing does precisely the same in preferring Microsoft results, but for a much wider range of terms than Google does and is much more likely to do so. “For example, in our replication of Edelman & Lockwood, Google refers to its own content in its first page of results when its rivals do not for only 7.9% of the queries, whereas Bing does so nearly twice as often (13.2%)”
As for the second part of the study, the study used a much larger, more random sampling of search queries as opposed to the only 32 samples that the first study used to portray Google as the big bad guy of search. And the findings of the second study were related in the beginning of the post; Google references own content in its first results position when no other engine does in just 6.7% of queries, while Bing does so over twice as often (14.3%).
So, what does this mean as an end user?: Google (and Bing, though less so) really are trying to deliver the best results possible, regardless of whether they come from their own services (local search, product search, etc) or not. It all comes down to preference.
