Advertising on Bing

its good if you are targeting US market (but not as effective as adwords though). Not sure about other markets.

There really are few types of products that Google doesn't like. It's more likely the landing page that is violating one or more of their rules. As Bing also has rules, and similar ones I might add, you may not be any better there. Best to work with the affiliate, make them understand that they need to change their page. If they can't/don't want to, don't use PPC to promote them.

Fix the breach then.

I find it so strange that people are willing to give up Google traffic when very often the fix is so easy. You have to know of course the rules and how to avoid breaching them and few seem willing to do that. They are more willing to tell Google where to put their rules and they'll use Bing instead. Well, guess what, Bing has pretty much the same rules.

QS has nothing to do with it. If you breach policy, doesn't matter how good you were or how much money you were making them. Let's take an example. A man -let's call him Pete Rose - is considered one of the best in his profession, a QS of 10/10. Unfortunately, Pete breaches one of his company's rules, let's say it was gambling. Pete, although well on his way to receive the highest accolade in his profession, is disciplined which includes not being able to ever receive this accolade.

The same can happen to anybody, no matter their QS. So my suggestion is to read Bing's rules and fix any problems there might exist. This can in turn get you back into Google's good books. Otherwise, you might find that Bing will suspend you too one day.

It's still pretty difficult to promote affiliate products via Adwords. Even with a quality landing page. It's much easier with Bing, and the traffic is still solid.
