Promoting irrelevant programs
Promoting as many affiliate programs as possible in an effort to maximise your revenue streams may sound appealing to new affiliate marketers just starting out. However there will come a point where your site will lose its focus, particularly if you are trying to adhere to all of these programs.
As a result, content quality will suffer, alienating your hard-earned traffic which will eventually drive them away.
Instead, focus on a small group of relevant programs your site will complement, as this will be far more manageable for you and far more rewarding for those who visit your site. Maintaining the purpose of your website and the confidence of your users you have established is key to running a successful affiliate site.
