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.
Plan your link structure. Start with the main navigation and decide how to best connect pages both physically (URL structure) and virtually (internal links) to clearly establish your content themes. Try to include at least 3-5 quality subpages under each core silo landing page. Link internally between the subpages. Link each subpage back up to the main silo landing page.
At our agency, we work with sites of varying sizes, from very large to quite small, and recently, we have noticed a trend at the enterprise level. These sites aren’t relying as much on Google for traffic any more. Not only are they not relying on Google traffic, but also, the sites are getting less than 10 percent (or slightly more) of their organic traffic from the search giant.
