SEO is the science of customizing elements of your web site to achieve the best possible search engine ranking. That is really all there to search engine optimization. Both internal and external elements of the site affect the way it’s ranked in any given search engine, so all of these elements should be taken into consideration. Good SEO can be very difficult to achieve, and great SEO seems pretty well impossible at times.

Ideally you want your site to be displayed somewhere on the first three pages of results. Most people will not look beyond the third page, if they get even that far. The fact is, it’s the sites that fall on the first page of results that get the most traffic, and traffic is translated into revenue, which is the ultimate goal of search engine optimization.
