I'm using Webalizer. Having a little trouble figuring out the best way to track AdWords click-throughs because I hide my own domain from referrers. Additionally, the way they suggest tracking is to direct the traffic to domainname.com?referrer=Something. Webalizer strips everything following a question mark.

Should I create a subdomain to send the traffic to, like something.domainname.com, or is there another solution?

Thanks!

You could create specific landing pages that aren't accessible from anywhere else, and track stats on just those pages - you'd know that all traffic there came only from your ads. The URLs for these would read something like www.accuracast.com/online-marketing.shtml which then does away the problem with ? and passed parameters.
If you like maintaining your site in neat folders you could even lump all landing pages into one folder (call it something like "google") and that way you can easily track all the entry pages and you want have unlinked pages floating around your root directory.
Tip: Make sure your landing pages reflect the design of the rest of your site completely.

Excellent ideas - using the folder especially - that will help tremendously. Sometimes the simplest solutions evade me!

Since I want them to come in on the home page, primarily, and that page is pretty dynamic, I'll have to find a way to redirect other than using my Apache config, because I've found that those redirects don't show up in stats. I can't stand meta-refresh... I guess another option might be to use a symbolic link to the original file on the server.

I don't quite know your website / business, so I can't speak authoritatively, but I've personally found much highger retention rates when I've created specific landing pages for each ad words group, rather than having them all arrive on the home page.

Perfect. These suggestions will work well for me. As I mentioned before, sometimes the simplest solutions evade me! Why always looking at things the hard way... must be some kind of geeky trait.

Thank you very much.
