Marty Note
Don't usually think of SEO "landing pages". Usually use "landing pages" to describe where paid traffic lands, but the distinction is lost when traffic and its origins are becoming as murky as it is now. Semantics aside this ariticle is full of some of my best tricks including personas, pictures and CTAs (call-to-actions).
