We're looking at moving our website from http://www.wikijob.co.uk to http://www.wikijob.com/uk as we spread our wings internationally.
Our .co.uk website has a PR6 and received around 1/2 million visitors a month, 40% international. The wikijob.com domain, while registered for a while, has not been used nor promoted.
I am concerned that moving domain could really haemorrhage our traffic and result in a loss of goodwill from Google, even if we use a 301, but equally, if we could transfer that pagerank to the .com domain, that would give us a massive head start around the world.
Should we do it, or should we start over with .com and leave .co.uk as is?
