I was wondering what the best practice would be when you optimize your site for mobile devices?
* to create an entire new design optimized for mobile devices and redirect the traffic to that sub-domain?
* to create a separate CSS sheet for so that the website layout changes when visited from a mobile device?
or anything else??
Ideally I'd like to create a totally different design for the mobile site and put it under a subdomain but I am not sure if that is good for SEO, if it created duplicate content etc so I'd appreciate any feedback on this.
Also what is the best way to detect a mobile device so you can redirect that user to the mobile site?
thanks a lot
