I have a site that covers merchants in the U.K. and USA.
The details of the content for each merchant is of course different.
But the layout and the content headings is the same for ALL merchants.
Currently you can choose to go to the US merchants or to the UK merchants.
I would like to split the merchants into one website for the US with its own url and one for the UK with its own url.
I would then have effectively two identical sites with the other editorial content being mirrored on each site.
The only difference would be the details in each merchant record.
Will Google and Bing (Yahoo) see these as duplicated sites and blackhat them.
Very important question for me.
