The essence of the phenomenon is that your website most likely has a “short head” (say ten or fifteen keywords that drive massive number of Visits) and usually a “long tail” (hundreds of thousands of key words and key phrases that drive five, ten, fifteen - few - Visits).
The really cool thing about the tail is that the thousands of queries in the tail are generic (”category“) queries which tend to bring “impression virgins ” to your site. People who are new to your franchise, people who have not made up their mind.
Find them first and you get first dibs on convincing them.
