Ranking in Google.co.uk Question.

I have a question with regards to ranking on Google.co.uk these days.

If I do a search for example 'used cars' in google.co.uk, it shows me results for used cars in my local area. For example say I'm in London then Google.co.uk shows me results for 'used cars' in london, regards if I type London or not.

So if I manged to rank, again as an example 'used cars' keyword to Number 1 in a Google.co.uk search, this wouldn't actually show up as a number 1 result with google using it's automatic location search.

So how does ranking a site say in the top 5 results or Google.co.uk work nationwide these days? (throughout the whole of the UK regardless of location)

Bump

No one can answer?

Can't help you there m8

lol, okay.

Anyone have any advice on this for me?

That is called LOCAL SEO and you can't escape from it. Google tried to provide the most relevant results according to searcher's details (cookies, location, etc.)

Look at the results. Most probably they are the local (area you are searching from) organizations which have the Google listings as, say, an organization based in London.
Furthermore, a guy doing a search from London, will get the most relevant results and get the organizations based in London. That's called Local SEO
Avoiding this, will require you to go for ranking the, roughly saying - nationwide keywords, however, the guy from USA typing "used cars" will get the results about the biggest authority sites and most probably those will be from London as no localization keyword was included in the search term. Even in some cases of search from other regions than London, the results might be same as nowadays all of the real-based services are trying to rank locally (different areas) and to geographically-based keywords. That's the most relevant way to sell service to the right persons.

Bottom Line: If you want to rank nationwide, you gotta have the authority website with most relevant content on it and your main keyword-optimized. Moreover, sub-keywords should be definitely area-related as well should have are-related-keywords optimization.
