If you have a website and wanted to add Google Adsense but for some reason was rejected, you can still make money with click ads on your site. You can use Revenue Pilot for click ads income. Revenue Pilot isn't as big as Google Adsense (who is) and my not be able to serve up relevent ads for some sites, but can handle most. Revenue Pilot's rules aren't as strict as Google so most sites are accepted. If worked right I think you can make as much money with Revenue Pilot as with Google Adsense. I use Revenue Pilot on one of my sites and I'm making a little money, but I can see that if I do a little more work getting visitors to that site I could make more money with them.
