Which is the best? CJ, Clickbooth, Azoogle, Amazon or any other? Which has the highest rates and pays via paypal?
There IS no "best" - it's all about what you put into it and how you're going to market. Are you doing organic and SEO? Are you doing PPC? Email? Forum? List-based leads? You can promote anything via numerous ways. I use amazon to monetize my (well established) blogs and I make money every month. I use Commission Junction for both banners and single products. Some things have $100 per sale, others only 2%. I get money from CJ every month. I also make eBay money every month. You can't just say what's best - what exactly are you doing to make money?
