If I was them (Bing), I would turn this blind test into the biggest ad campaign ever - spend a billion dollars if that's what it takes.
And there is the big IF. If Bing is winning by far
! Otherwise why would anyone switch to Bing?
Difference between Bing and Google is that Goodle is a search engine company, while Bing is just a project of MS. To me it's like comparing a car made by top auto company(say MB) with a car that is made by a company that has nothing to do with cars(say Phantom Corsair by Heinz). The letter may look fancy with fancy gadgets, but when it comes to buying you want something stable and something that is made by people who have experience and vision. What is Bing, where was it, where is it now, where is it going? Go outside and talk to people, at least in US I haven't seen a person who would search something on bing, Yahoo yes, Bing no. Even MS guys agree that Bing is a fail.
I just did an image search on Bing, on the keyterms that I rank pretty well on G, and guess what I see same results. I have an impression that they can't say which one is better so they go and steal results from G. From one of key terms I receive 1k+ visitors a month from G. From Bing? 0 for this year. It wasn't on the firs page from the beginning, it climbed because of high CTR. But why did it climb on Bing?
