Without going into too many details it is an iterative service that compiles data from actual user traffic, where the best placement of ads are coupled with the new optimize google search algorithm data. This is something that starts out rough and gets better over time so now we don't have people just randomly changing things it is a cloud based server farm using data analytics and intelligence that systematically maps user interactions to optimize the site. Bottom line, please be patient while the site optimizes itself. Thanks!
