I get next to none traffic from Bing... The only one i know who uses bing would be my mother, and even that does not happen too often.
it is not easy to say .... l used to get more traffic out of bing , but now , l hardly use it ,maybe it is better than before!
Actually I am starting to see about 2% of my traffic from bing and that is only because bing is somehow picking up popular news topic keywords from certain articles on my sites.
