Mobile Domain \ URL Structure SEO questions

[CookingCom]

Hi

We are making a mobile site for our site for one of our partner sites and I would like to know which one of the following URL structure you recommand as far as SEO concerned?

mobile.mywebsite.com

or

mywebsite.mobi

Also, should I worry about duplicated content on my mobile site?

[Webmaster_SEO]

Any of the above variations can be used for mobile site.

Though if you see that most of the big sites use m.sitename.com including Google so might want to use that one instead.

As long as you can accurately detect the mobile device and 301 redirect to the mobile version of the site you do not have to worry about the duplicate content. Here is the link to Google blogs which talks about basic problems and solutions for the same while making a mobile website: http://googlewebmastercentral.blogspot.com/2011/02/making-websites-mobile-friendly.html
