Hi
A lot of the advice for affiliates is to "pre-sell" the deal so that you're sending customers who are more inclined to buy to the main site. This is good advice.
This implies that you need a web site. But it doesn't have to be an all-signing, all-dancing site. A blog works fine for many affiliates.
Ideally, keep the blog under your control. Which means hosting it on your site rather than using a free blog hosted at Blogger or wherever. If your host uses cPanel, go to the Fantastico link and select Wordpress for a one click install.
Then use your blog to pre-sell and place your affiliate links in this part.
Hope this helps
