Scott Cowley provides guidance on how to teach SEO effectively to students. He recommends starting with local SEO since it is relatively straightforward, then moving to YouTube SEO which is more complex, and finally teaching full website SEO. For each topic, he outlines the key ranking factors and provides exercises for students to analyze search results and optimize pages. The overall approach is to ease students into SEO concepts from easy to more difficult, while giving them hands-on practice at each stage.
