According to the results of www.seitenreport.de I have a lot of issues because of duplicate content...this in turn affects my SE positions. I use a URL Alias module with Drupal which makes my URLs more SEO and User friendly. The redirects should take place through 301 redirect. I also installed a module which should keep duplicate content at bay...but it doesnt seem to work. Does anybody know a tool to measure the impact of my duplicate content issue on my SE rankings or to measure if there is duplicate content as designated by the SEs? How may I solve this issue? I use Drupal 5.x at the moment. The Site I am talking about is www.magicofword.com Thanks for your feedback!!
