What can you do that the merchant doesn't? That's the key to value.
Today a guy named Michael who is a notable authority on affiliate internet marketing made a remarkably profound (as usual) statement that sheds light on two factors that are important to keep in mind while diciding what your website(s) link strategy should/will be in the next year.
Michael points out that -
1. A site can be succesful pomoting one merchant. Yet, it is more rare.
2. The most important thing to focus on when reviewing opportunity and planning what you will do is "what can you make that the merchant has not yet made". Or in other words what new value can you present to users on the web that is not available yet online.
Here it is on abestweb in Michael's words.
