Only ranking well when "UK" is added to search term

[Solid_Web]

Hi, what does it mean when a lot of our keyword phrases rank only when "UK" is typed in the search term?

For example:
"boxes" (not in top 50)
"boxes UK" (38)

"big storage boxes" (45)
"big storage boxes UK" (33)

We haven't attempted to SEO the pages for search terms with "UK" appended to them. Our domain is a co.uk domain. So, what reasons could there be that are we ranking in such a way?

Hi,

From above example I can tell you very clearly that keyword with UK is less competitive that is why keywords with UK appearing on better position in comparison to other keywords even without doing any seo.

Second as you said that you are not doing any seo but I presume you could have use UK anywhere on webpage or define target country as UK  in webmaster tools . If that is not the case your site is ranking for UK keywords because your domain is co.uk

Thanks
