Many article directories won't accept your articles if you simply put affiliate links in it. So you really need to own your own site. One way to do this is to set up a review site in which you compare and review competing products - for most of which you also have an affiliate account. An example of this is SmokingReviews.org. You then promote the review site which, in turn, promotes your affiliate links.

Perhaps the simplest and cheapest way to do this is to go to Squidoo.com and create a "lens" (same as a web page) in which you recommend and write about various products. In there you can put your affiliate links.

Then use the Wizard to point people to your Squidoo lens. That way YOU own the links. If you just put an affiliate link into the resource box, you are giving away the link to the destination site. Suppose they go out of business or end their affiliate program? Then all your links are worthless.

If you own the links, then if that happens, you just adjust your Squidoo lens and promote a different product instead.

To start with you can even simply post your article on your Squidoo page, just to get it up and running. Then, as you go along, add more content to the lens to build it up into a more authoritative site.

Another way to do the same thing is to set up a blog.
