It seems, and I’ve been hearing this from Google themselves as well as from blogs and other companies, that buying up the long tail of google search terms is an efficient way to get customers. This means mining your site for the search terms people use to get there, and even using a tool to do so for you. However everyone seems discount the internal cost of administering the campaigns, and I’ve yet to see a tool that automates the selection, placement and management inside google of the adwords. Perhaps one exists.
