What is this

[92EvilTalon]

Well I googleed your request and I got this site: How Does the Adsense spider work?

Then I went to Wikipedia and found this: Adsense

Then on Wiki I also typed this: Search Engine

Basicly from what I gather. Adsense helps the web crawling bot gather info. So when you type in a google search. It has that info from adsense. Thats what I gather. Do a google. And as for Yahoo! Slurp could not find any info on that. Then again Yahoo! was using Google back in the day until 2004.
