Important link building question for me!

[activitysuper]

Hi,

When building backlinks how important is the location of where the website resides?

For example, if I was targeting a search term in Google UK, will link building from websites hosted on UK servers have a higher positive impact on rankings then building links from websites hosted on US servers?

Lets say in the above UK hosted is better, what if you have 2 websites hosted in the UK but one with .com and one with .co.uk, I take it from a domain point of view the .co.uk will have a better impact on SERP's then the .com.

Now looking at the above from a more wider scale lets say I have the following:

A .co.uk website aimed at a search term in Google UK.

Example:

1. 100 backlinks from websites hosted in the US with .com extension.

2. 100 backlinks from websites hosted in the UK with .co.uk extension.

Is it a FACT that number 2 will 100% be more beneficial in UK rankings?

Cheers

I will just quote the guys from SEOmoz:

Global Popularity

The more popular and important a site is, the more links from that site matter to the search engines. Getting lots of local, topic-specific links is great, too, but to earn trust and authority with the engines, you'll need the help of some powerful link partners.

Local/Topic-Specific Popularity

The concept of "local" popularity (first pioneered by the Teoma search engine) suggests that links from sites within a topic-specific community matters more than links from general or off-topic sites.
