Bing/Yahoo combination is really showing some interest by the public. I mean in Singapore, most of online news readers reads on Yahoo news where ads are shown much more agressively than Google. Though this still doesnt mean that Bing has overcome Google. Lots of room of improvement but Bing/Yahoo is definitely picking up.
If you are an affiliate doing PPC ads forget about google. bing is a lot more affiliate marketer friendly.
I think google is better, especially in other country's then the US. It really give's better results then Bing..
The only thing I believe is different is it's owned by Microsoft and forced into our faces when you first open the browser on IE and they don't have a large database like Google.
I use mostly google its one of the most famous browser in the world. many peoples don't know about bing but everyone knows about google . when i will use any add then may be i will go for bing but for now my vote for google.
I have a website that gets a lot of traffic from Bing. That's with no backlinking at all. But as a searcher, I still think Google is better. Starting to luck duckduckgo though.
Maybe I'm mistaken, but Bing doesn't usually seem to provide results to pages as much as just the domains. Even though I think Google is pure evil, Bing doesn't wow me either.
Traffic from Bing (Combined with Yahoo or any search engine that use Bing result) is still in the low percentage compared to Google.
