What are the best way to target any country using SEO?

[niraj]

How can we target any specific country for seo purpose. One of our client based in UK having .com domain name and his datacenter located in USA.

Now he want to optimise his website for UK customers .

My main concerns are is Domain name and location of datacenter affects ranking in google.co.uk

Similarly domain name for india .in but datacenter in USA can affect ranking in google.co.in

Any Idea...

To do well in UK searches and "uk pages only" searches, your client must have either local (UK) hosting OR a .co.uk domain.

If he already uses the .com, then of course he'll need to be mindful of duplicate content issues.
