Solid analysis on this tough topic Rand. It will definitely be interested to see what in-serp features Google continues to add to keep you on their site as opposed to clicking through to a website. I think SEOs need to take more consideration into branding and content marketing tactics in order to supplement potential lost organic traffic as time goes on.
Lynn, you have one of the best sites for affiliate marketing that I've ever seen. Just read your interview with Rosalind Gardner and found some interesting nuggets. Marketers should note the intuitive and spontaneous way you approached a niche and keywords. This is usually where "paralysis analysis" begins … some spend weeks with keyword and research tools until there is no "creative energy" left to build the site.
