did you lose rankings in the transition process? Did the move pay off?
Both moves paid off.
I now have an almost duplicate of example.com running on example.co.uk and that's gaining in traffic every day from G.co.uk. Example.com in G.com has kept steady and only affected by an Italian scraper which copied my original site (the one now running on example.co.uk) and which I have been totally unable to do anything about...its running on an Italian server under a .eu
The UK site on a .com which now has everything under the .co.uk has regained all its former positions and has better traffic than ever...this I put down to it being a .co.uk with G's geotargeting working in its favour.
Interestingly it's made absolutely no difference in Bing, the UK.com was doing well in that and has been a straight replacement.
