I had the impression that you can do this? is it by tracking referers to your site? if so, can someone tell me the exact string from google I should be looking out for?
...unless, and I'm thinking out loud now, on the destination URL on your adwords ad, you enter some variable , say [example.com...] and then u have some server side script detect this and grab the referer...?
