Mobile Subdomains, SEO and Content duplication

     
7:11 pm on May 29, 2013 (gmt 0)



We are about to launch our dedicated mobile site on a subdomain, m.example.com

My question is, how do we avoid content duplication? Do we use robots.txt to completely block the m.example.com site?

Any suggestions would be greatly appreciated.

thanks,

use canonical to point to the original content.

Google's gotten pretty smart about this stuff now.

Here's some info that's probably mostly still relevant.

The approach is simple to tackle the issue:

1. Using Canonical tags on all pages of Mobile site to point to corresponding pages of Desktop site
2. Use Alternate tags on all pages of desktop site to point to corresponding pages of Mobile site
3. Make sure Googlebot Destop can crawl both versions of site
4. Googlebot-mobile should only be able to crawl the Mobile site. This can be achieved by adding a 301 redirect from desktop to mobile site (respective pages) when detecting mobile browser/googlebot-mobile

Just follow above steps and you would be perfectly fine with your rankings. We are using this approach and it works beautifully.
