i started optimizing this particular site... after just 20 days of SEO work, it's now ranked number 1 for its keywords, copywriting experts, at google.co.uk the site is http://www.copywritingexperts.co.uk but u'd have to go to http://www.google.co.uk to try the search... this proves that google provides customized search results for the client's country.
Good job, but you should also know that you have nearly no regional competition for this search term.
it's no big deal. Your site is ranking on "copywriting experts" in Google UK bcoz the domain name "www.copywritingexperts.co.uk" contains this search term, and since your domain is country specific (.co.uk) it's ranking well on Google UK.
Although competition might seem tight in the global arena or the major USA, it is often seen that a popular niche or keyword is not flourished with a lot of competing websites in the domestic arena as expected. These days, it might be a scope for the new webmasters to bypass the over saturated market, and target a somewhat domestic approach.
