I have a question. A client is reluctance with appending Coremetrics tracking parameters (e.g., ?cm_mmc=LS-_-1-_-2-_-3) to the end of these links citing SEO/duplicate content as one issue. I suggested that we appended such parameters in a cookie. From an SEO standpoint, having those parameters will create a dupe content problem. Are there any other solutions or workarounds that I'm missing?
