I'm very slow out of the blocks on this one but want to start redirecting my non www. domain to my www. domain (i.e. mywidgets.co.uk to www.mywidgets.co.uk).... ....but what one do you link to the other? Is it based on what Google shows in your SERP as being the main - or which one sends most visitors to your site from analytics tools - or is there another way of working this out ??
