Has anyone been able to track an adwords bot?

Does it first visit the destination page, then check the amount of relevant keywords and compare it to the ADs?

The reason I ask is because, if an AD has dynamic generated URLs, then the adwords bot would have to crawl each dynamic url that has the listed keywords in order to determine how relevant the AD is to that dynamically generated page.

For example:
ad(keyword) goes to:
lp1(keyword1)
lp2(keyword2)
etc...


Does it work like this, or does it crawl the page only after there has been some visitor clicks to it?
