Best way to geo redirect

[Grumpy_Carl]

Hi

I have a couple of ecommerce websites which have both a UK and USA store. At the moment I have both the UK and the USA domains sending me traffic from UK and USA search engines which means that a number of users are clicking a Google page for the store not in their location, ie UK people are clicking on a .com listing and ending up on the USA website.

What is the best way to automatically redirect people to the correct store for their region? If I use an IP based auto redirect system would Google see some of the pages are doorway pages?

Thanks

You can as far as Google  is concerned, but your uk site may not get crawled, as you will be redireting googlebot as well. you must not detect google bot and make a exception just for them or then you will be cloaking, google bot must go with the rest of the US ips.

A better idea my to try this
