I've got a site based on the dentist method posted a while ago but it targets the restaurant niche instead. Now my site doesn't exactly have a lot of information; it's got a slider that says"Best Restaurants in Town, Quality food rah rah rah" and a few pages going over what italian food is , turkish food is etc but nothing about those in the area. Now i only have the .com domain however the .co.uk is available (I'm targeting the UK). The .com is currently rank #8 in google.com but #31 in google.co.uk. I'm guessing instead of backlinking UK sites like mad it would be easier to invest $4.99 in the .co.uk domain. My question is how do i go about doing it? Do i simply redirect the .co.uk to the .com as this is already established? Or do i changed the site to have the .co.uk as the primary domain and what effects will this have on my rank already? Hope someone can give me some advice!
