If you have a site with adsesne try doing some testing. Try to write about a subject in a roundabout inderect way. Once the mediabot finds it, you will see some pretty on target ads. If they are that good at figuring out what a page is about when you are trying to be obtuse, imagine how good they are when you write about something in a straight-forward fashion.
