I have a website which uses xxx.net which is currently 2nd on google with a PR4 for its main keyword. I want to re-design this website but i really cant risk it droping So... I want to setup a site very similar website using the xxx.co.uk extension. Can you please tell me if google will penalize against this method ??
google wont penalize as long as u don't spam. However then ur xxx.net will be in a competition with xxx.co.uk
see if u want to redesign your site than no need to go for new domain name.if wont affect your ranking as i have already done it with some of my sites and all are performing very very well.
