In this video interview, SEO expert Stoney deGeyter explains his approach to keyword research, not only for a few keywords, but for the hundreds of keyphrases needed to optimize, say, a large e-commerce site. The approach involves three main stages: finding and organizing core keywords, and then arranging a campaign with the qualifiers to those core keywords.

First, find the core terms that are applicable to your site, that is, generic keyphrases with no qualifiers, such as “motorcycle battery.” Next, assign core keywords to the particular pages and sections to which they apply.
