Duplicate Content - Mobile Site

[nsmith787]

We think that a mobile version of our site is causing a duplicate content issue; what's the best way to stop the mobile version being indexed. Basically the site forwards mobile users to "/mobile" which is just a mobile optimised version of the original site.

Is it best to block the /mobile folder from being crawled?

If you want to block the /mobile folder from being crawled you would need to set up a robots.txt file and input this text:

User-agent: *

Disallow: /mobile

Personally, I would use the rel=canonical tag and tell search engines that the preferred version of the page would be the non-mobile version. You can learn more about rel=canonical here...
