SEO 101 - Search Engine Optimization
I've got a new recommended resource. (It's not actually new, but I haven't recommended it before now.) It's Michael Bluejay's article about search engine optimization. Obviously a lot of people in affiliate marketing want to make money by getting good search engine rankings, and Michael's article will help you do that. His approach can be summed up as "build good quality web-pages", but he goes into a little more detail about how to do that, and about some of the more technical aspects of SEO in his article too.
Along similar lines is an SEO article on Aaron Wall's search engine optimization blog about creating the ultimate resource on a subject as an SEO strategy. Fine reading, this.
