The most important rule of choosing an affiliate program is to know your target audience.Another point to consider is whether you really want to join every single affiliate program that comes your way. Some studies suggest that sites that make the most money from affiliate programs are affiliates of only a small handful of programs. Furthermore, concentrating your advertisements from one network may allow you to be paid faster. If you advertise for hundreds of different affiliate networks on your site, you may wind up earning only (say) a few dollars per month from each network. If your advertiser's minimum payment amount is higher than what you can earn each month, it may take you a long time before you accrue enough to be paid.On the other hand, that formula does not necessarily hold true for every site. For example, if your site has a particular theme, and an affiliate network only supports one or two suitable advertisers, you might want to sign up for a few affiliate networks so as to get a greater number of relevant advertisers.
