With Adwords, I'm sure you're aware you can use the following tracking URLs for your logs:
www.yoursite.com?referrer={ifsearch:GoogleAdWordsSearch}{ifcontent:GoogleAdWordsContent}
Can someone tell me if the?referrer={ifsearch:GoogleAdWordsSearch}{ifcontent:GoogleAdWordsContent} part is visible to the visitor when they click through to your site from a Google ad?
Or is this bit invisible to the user?

If you really don't want the user to see it, you could redirect him to a different page.
