Lauren Litwinka gives us the anatomy of a landing page and tells us how to optimize them. She starts with three types, including one that causes the site visitor to take action, or links to more information. For each of the three types she tells us about nine or 10 sections on the page and the best way to use each. Rating each section also becomes important -- per relevance, quality, location, proximity and prominence. The actionable tactics come from a session delivered by Bryan Eisenberg at Search Engine Strategies this week in New York.
