Welcome to the Q&A Forum

Hi Rob, Couple of things: 1. You can check if you have a proper 301 in place using tools like URI Valet. For example, here's a report for the SEOmoz blog. If you include a backslash, it automatically redirects to remove it: http://urivalet.com/?http://www.seomoz.org/blog/#Report 2. An actual better way to address this is with canoncial tags. A proper canonical on the homepage (pointing to the version without the slash) will address all duplicate content errors, and possibly also address other versions of your URL you didn't anticipate, like: www.example.com example.com www.example.com/index.html 3. Although SEOmoz will flag these as errors (because technically they are) in reality a trailing slash on your homepage isn't a big deal. Google has gotten pretty good at figuring these URLs out. That said, it's still important to address other areas of duplicate content on your site. Hope this helps. Best of luck!
