In the Adsense admin area, select the check box next to each individual keyword you are using and give each one its own URL. So if you URL is www.example.com/widgets.html make it www.example.com/widgets.html?AW-individual-keyword.
This will show up in your server logs as a separate URL from widgets.html, indentifies AW as the source ad program and the specific keyword.
Also, if you suspect you are getting invalid/fraudulent clicks from Adsense or other Google partner content then you can use this same tactic to identify the exact keywords that are being abused. I have used this tactic twice to get full AW refunds/credits in click fraud cases.
You can also grab anything after the? and stuff it into a cookie using some simple javascript. You can see the javascript on my main page at <link removed>.
Note that the "?" does not have to be after an actual file name as seen in the above example.
Note 2: That javascript will be coming down in about a month or so with a site redesign in which the javascript will be called from a file to improve search term density. If it's not there when you go to look for it just sticky email me here and I'll email it to you.
