Why there is rank difference of site in Google.com & Google with other extensions

[seomixi]

I am not able to understand that why there is a difference in position of my website with same keywords in google.com and google.ca or google.ca. On google.com my site is at 7th position with a keyword and with that same keyword it is at 5th page in google.ca. Can anyone here tell me the reason please? Your answers and experiences are most welcome, so please share.

I think its because .ca and .com each have their own rating.. They are not running as one system..

yes there is a lot of difference for the keywords in the google extensions. It is all based on the hosting and targeted location.

It's called geographic targeting and it is something you should think about carefully because it is extremely important for rankings!

your domain extension has something to do with it. if you have .ca name, then Google will naturally think that your site is a Canadian site targeting Canadian audience. same goes for co.uk domains which will typically rank better on Google UK than US.

There are lot of other reasons like where you host your site, where you get backlinks from, and which geography you selected under Google webmaster tool.

Since there are lot of variables to play with, a single site will usually rank the same across all Google location.
