Search Engine Optimization is how favorably your site is seen by the search engines. Good SEO has two components, onsite and offsite. Onsite SEO is having your keywords in your titles, description, and main content, but not so much that you are stuffing. Off site SEO is how many anchored backlinks are pointing to your site. Many webmasters disagree about where to put emphasis. I know from experience that the more anchored backlinks you get, the higher in the SERPS your site will place, regardless of the onpage SEO.

Some of the *methods* which actually work well are called "Blackhat SEO" (cheating) These may work short-term, until the nasty little spam site gets banned.
