Who should I go with? Azoogle/ClickBank/Clickbooth/Amazon I need a company that pays on time. Has ads that convert and pay well. Great User interface. Thanks to all the future replies.
It depends on what type of site you have. If you have electronics amazon would be good. If you have ebooks clickbank and the ads for forums or sites that do not have products in amazon. If you pick right affiliate program you will make more money than paid ads.
think of it this way. With paid ads, the person paying you is definately making more from your ad than they are paying you (if they keep renewing that is), so you are leaving money on the table.
Sign up with couple off them. Try them and see which will work best for you and your site. There isn't a program that would work for everyone.
That's a very hard question if we don't even know what you want to use them for. Out of them I would go for Azoogle then Clickbooth then Amazon and then Clickbank last.
