I have a College related site, so once in a while I get a few affiliate referrals for textbooks. There isn't a real single program I'm promoting, but I'm using a CJ program that pays 8% and then of course the Amazon which pays what like 4%? Should I just stick with one program? And, which program would you guys go with...The well known, lower paying Amazon? Or, the 8% on CJ?
Personally I use both Amazon and also AbeBooks via Commission Junction. Up until now Amazon has been doing best, but recently I've been getting more sales from AbeBooks so the balance is shifting. I'm going to run both in parallel for a while again to see who does better. The books I'm promoting are fairly esoteric acedamic ones, so it may depend on your market.
