Crawler reporting incorrect URLs, resulting in false errors...

[Clements]

The SEOmoz crawler is showing 236 Duplicate Page Titles. When I go in to see what page titles are duplicated I see that the URLs in question are incorrect and read "/about/about/..." instead of just "/about/" The shown page duplicates are the result of the crawler is ending up on the "Page not found" page.

Could it be the result of using relative links on the site?  Anything I can do to remedy?

Thanks for your help!

Hey Frank! This definitely sounds like an issue with relative links on the page; if the crawler sees it, he'll follow it, and continue to do so indefinitely, causing a super-long URL with the same sub-page listed over and over in the URL. I actually see this bug a fair amount. I'd recommend you look at your page code, try to find relative link tags, and then fix them on that side of things.

If you think it's a bug and nothing in your code, you can always send an email to us at help@seomoz.org - we'll be able to take a look and make sure it's not a bug on our side (make sure to send your PRO email address, the campaign with the issue, the URL with the issue, and any relevant screenshots/examples to help us diagnose). In my experience, though, this is always because of a relative link I find in the source. If you need help with how to fix that, you may want to start another thread here in the Q&A and post your page's source or URL. Hope this helps!
