Geographical Location is of High Preference in Google SERP's

Just noticed that one of the leading website that used to rank within the top 5 position of Google.com for the term "SEO Company" has suddenly disappeared from the top 100's.

However the same website is ranking within the top 5 of its Google Local search engine.

It seems that Google has started to differentiate results based on their geographical location. The best ways to have your website listed in regional search engines is through

a) TLD of the domain name
b) Geographical Region Setting in Google webmaster tools
c) Attain Links from websites with the region you are targeting as in TLD or hosted in the targeted country.

I am sure that above mentioned points combined with some basic on page and off page initiatives on the website would surely boost up the rankings for your website in regional search engines.
