Sponsors that convert with PPC Ads
 

Best sponsors that does with bing.
Also niche niche..

see cigz

Does bing even allow it?

bulk candy..

Pick ones that are ultra niche and they should do fine.

I used to push this a lot back in the day with Google and Yahoo and was making mid-high $X,XXX/mo.

Problem is someone will copy what your doing and drive up your costs, so always be prepared to have a bunch more campaigns ready to go live.

1. pick a sponsor
2. write multiple ads
3. ???
4. profit?
