What is the best tool for cloaking the google adwords bot/ips?

the fantomaster spiderspy IP list is the most complete for Google bots of all kind.

IPLists.com does have the adwords bots in it.

Most folks cloaking with adwords are using cookie cloaking or referrer cloaking it seems. Overall, a bit safer.

all of the methods cited will work with Adwords.

1. ip delivery depends on a list of the Google bot IPs -- search and PPC. Spiderdspy has the most complete list, iplists.com has the adwords bots in it as well.

The IP list *is not* the big deal. It's the manual review -- especially on the content network.

2. referrer cloaking works well with any form of Google PPC (search, content, placement) because there is a finite list of referrers.

3. cookie cloaking is very popular with the Acai and teeth whitening flogs. I am not aware of any commercial cloaking script offering cookie cloaking. wpCloaker intends to with the next release. The basic method is a combination of dropping a cookie in the tracking link and then having the redirected page check for the cookie and serving the content or the offer based on that.

I don't see how any method would get past a manual review. In fact... it's impossible. Google can use proxies.
