With pay per click programs such as Google Adsense, there is another way to earn money from advertisers by building a scam where the money flows like this:

* The advertisers pay Google for clicks in the hope to sell something.
* Google has a bunch of publishers that own a website and run banners for them. Google pays (a high percentage) of the revenue to the publisher.
* Some of these publishers aren't honest, but Google (tries to) detects fraudulous clicks and suspends them, so they need to hide the additional clicks better.
* Somebody with a botnet generates the clicks from a few hundred machines and makes sure they look as innocent as possible. Keeps it a low profile while at it. Of course the botnet owner will want a share from the publisher.

Bottom line is that the advertiser pays in exchange for a bot visiting him. SANS - Internet Storm Center - Cooperative Cyber Threat Monitor And Alert System
