Drupal infinite URL depth? SEOMOZ treating as duplicate content

[dresults]

I'm monitoring a subdirectory of my site on SEOMOZ but with catastrophic results. It's finding infinite duplicate content e.g.www.example.co.uk/product/samples/product/product/productand so on...

The website is running on Drupal. Do you have any ideas on how I can solve this?

Try adding something like this to your robots.txt file:

User-agent: rogerbot
Disallow: /product/samples/product/
Disallow: /product/samples2/product1/
Disallow: /product/samples3/product4/

etc...

Thanks Scott, this is really helpful.

Out of interest, would disallowing '/product/samples/product' automatically stop the bots from indexing all the pages underneath this, too such as '/product/samples/product/product/product/'?

Yes, anything deeper would also be blocked.

I'm not a Drupal expert, but it sounds like you may have some kind of relative path that's getting perpetuated. Robots.txt could help as a patch, but I'd definitely want to solve the crawl problem, as this could spin out into other problems.

Have you tried a desktop crawler, like Xenu or Screaming Frog? Sorry, it's tough to diagnose without seeing the actual site, but it's almost got to be a relative path that's causing "/product" to keep being added to links.

Can you list the modules you're running?  What e-Commerce module are you running?

I'm having this same issue with a new drupal site. Does anyone know the underlying cause and how to fix it.

Would any relative path cause this?

Thanks.
