Newly Purchased Domain with no Content has PR 4

[dailypress]

I was lucky enough to buy a short one word domain (.com).
I have linked to this domain from my other website and noticed even though the website has been empty (blank page) the Google PR is 4/10.
how does that work? Im starting to wonder if Google checks how many times a word is on the web. For example, lets say I owned the domain Word.com (admin, please feel free to edit) and Word was mentioned a million times on the web, would that cause the PR to be high?
thanks.

My understanding is that PR is an algorithm based solely on which other pages are linking to the URL in question (and their PR)
The number of times the word is on the web is irrelevant, otherwise sites like "and.com" or "the.com" would have unbeatable page rank. :-)

But only ONE of my websites is linked to the new domain.
I checked and there is no other website linked to my new website.

PR is based on the links to the page. It's a mix of quantity and quality.

Domains that are blocked by robots.txt and have never been crawled have pagerank, it's independant of the content.

what is the page rank of the page you linked to the new domain

is the new domain a fresh registration or did you buy in auction or freshly dropped?

Was the domain purchased out of the expired lists?

Rather than use the various indexes to search for backlinks, I prefer to first search for the domain name text. This will reveal sites that reference the domain and use javascripts or nofollow tags to link to the website in question.

On MSN Search/Live.com, Ask.com and Yahoo.com, just search for the plain text domain name i.e. example.com

On Google precede the domain name with a plus + sign +example.com

This should give you a little more info.
