Reducing traffic from a particular country

[whis]

We are having a quality/ relevance issue with some of our traffic. One of the problems is that we are ranking well in certain foreign countries, which is driving irrelevant traffic to our site (as we only really cater for UK residents).

Is there any way to suppress our overseas Google rankings whilst retaining good performance in the UK?

Thanks.

Are you using the hreflang tag which helps Google crawlers understand that certain pages, section, subdomain or country code level domains (cctlds) is targeted for a specified country.

If you go to site settings in webmaster tools you can set your geographic target to United Kingdom which may help.
