Getting affiliate links is the easy part. Having a place to host them—now that's a little more involved. Having a place to host them where people will convert to buyers—that's even more work. You need to create a place where people can find you, where they'll want to come for information or assistance, and where they'll leave only to go complete the sale (even though they may not realize they are 'leaving'). Nevertheless, it can be done.
But before you do anything, you need to structure a game plan. You need to write the plan that gives you all the potential for selling that you need.
