I ran into a site that consists of an Adsense block, a long article, and at the bottom are a bunch of links for an assortment of unrelated topics (Stocks, Vitamins, Loans, Flowers, etc.)
The links simply pass the topic in this manner: index.php?q=stocks
When you click a link, the AdSense ads switch to that topic, yet nothing else on the page changes (including the unrelated article which remains exactly the same.) The topic is nowhere to be found in the html.
Is it likely that the site is using cloaking techniques to detect Mediabot and then feeding it content to influence the ad content or is there something else going on?
