Linda,
Correct - it is inflating the traffic we are getting from these print sources. The redirect is generating a 301 status code so it seems like it is set-up correctly. We have about 5 other vanity URLs for that site that Google has decided to rank as well, as far as I can tell there are no sites linking to these URLs either. The website is database driven so the resulting URLs to have additional parameters which do make the URLs longer and not as clean as the vanity URLs. I was thinking about trying canonical link tags. I would just put that in the landing page and the http header for the redirected URL correct?
Thanks for your feedback
