I often use Webtrends campaign parameters to track ads on affiliate sites and other incoming links. The link looks like www.site.com/product.asp?id=12&WT.mc_id=LinkFromAffiliate

The parameter that shows up in my Webtrends report is the WT.mc_id parameter. I've noticed that these parameters show up on the URL in the Google SERPs sometimes, and I'm worried about duplicate content issues as well as messing up my ad reporting metrics. I am trying to figure out a creative way to get Google to index the page but without the tracking parameter on the URL. It makes no difference to the content of the page, it's purely so I know that somebody clicked my ad.

Here is my thought: write a script that checks to see if the user agent is Googlebot, and if the URL contains a WT.mc_id parameter, give a 301 redirect to the current URL minus the WT.mc_id parameter. Would this work? Any other ideas?
