Two sites with same content in different countries. How does it effect SEO?

[fredrikahlen]

Lets say for example that we have to sites, example.com and example.co.uk. The sites has the same content in the same language. Can the sites rank well in its own country?

Of course all content could be rewritten, but that is very time consuming. Any suggestions? Has anyone did this before or now a site which has?

You need to add hreflang tags:

Basically tell Google to index the .co.uk to Google.co.uk visitors and everyone else sees .com
