We have some issue with duplicate content on Google SERP. The problem is that we are using Click Tracking on Webtrends that adds a parameter after the URL. This is what a URL can look like when Webtrends loads on the webpage:
As I am aware Google Crawl the links and adds also the parameters so this content is duplicated because if you remove everything after
?WT.ac the same content is shown.
How can I prevent either Webtrends to stoop adding this or make Google not crawl these parameters? I have seen some ideas but not found a real answer I can use:
- Add self-referral
- noindex on parameter "WT.xx=.*"
- Add the parameter to a meta-tag
I am not so familiar with which method I can use and is the best?
