I know that at the end of the day I have to learn about all of them and I have already tried CJ and Clickbank so far but based on your experience which one is the best affiliate program and why?
The best program? Neither is better than the other. Its the products in them that might be of interest to your visitors. That's the hard part.
For example between CJ and Clickbank I choose CJ because of better advertisers and better interface and reporting. I want to know what the preference of people that used different affiliate programs is.
The best one is whichever makes you the most money. That will depend on your site and/or marketing methods, as well as working with a reputable company that pays you. (What sucks worse than not making money is making money but then not getting paid!)
I like CJ as well. Others will prefer places like NeverBlueAds and PepperJam etc. based on better customer support.
LOL its funny how people post this question like every month, it is like asking what is the best store in the world. Different networks offer different affiliates. The question is which retailer has the best program. Based on your response I am assuming you are asking which Affiliate Network is the best and not which affiliate program is the best. I use all 3 major networks including: Google Affiliate Network (GAN), CJ, and Linkshare. Why would you limit yourself to just 1? when you can use em all. As far as the best affiliate program, you would have to check their EPC and their network rankings and figure it out yourself. If your site is about clothing and the best affiliate program is selling electronics, then the best affiliate program FOR YOU isn't the best affiliate program, get it? It's all about your niche and your marketing skills that will show which program is best for you.
There's no best affiliate program. Just join a well-known program with good reputation and support time. For example: Join Amazon Associates to promote physical products, CJ and Clickbank for digital products and Hostgator for web hosting clients.
I favor Clickbank, if thats what you're talking about. Why? Better conversion. But thats just purely me.
From my experience, CPA offers convert very well compared to traditional CPS offers. Sign up for some reliable cpa networks and try to promote their hot offers. Best of luck to you.
