Google toolbar shows you the pagerank (PR) of a web page (pages not websites), but this is not a true pagerank value that Google holds. This cannot be calculated. Just build a lot of quality links (from high PR pages) and your PR will increase.

Page rank is calculated by the quality of the links to your website. If websites with higher page rank link to you this will increase your page rank. Google toolbar shows your current page rank but this is updated like 3 times a year so you might not notice a change to your page rank for some time.

Page rank should help your position in search results for certain keywords. If 2 sites have the same keywords the 1 with the highest page rank will appear higher in the search results.

Pagerank is a measure of other pages with pagerank linking to you

Google calculates your pagerank using a "top secret formula"

Only google knows a page's actual pagerank. They periodically export a rough representation to their toolbar application

I reported him when I made the post. Alpha has obviously looked at him (before my report) as his links have been removed.

PageRank is defined as follows: We assume page A has pages T1...Tn which point to it (i.e., are citations). The parameter d is a damping factor which can be set between 0 and 1. We usually set d to 0.85. There are more details about d in the next section. Also C(A) is defined as the number of links going out of page A. The PageRank of a page A is given as follows:

PR(A) = (1-d) + d (PR(T1)/C(T1) + ... + PR(Tn)/C(Tn))

Note that the PageRanks form a probability distribution over web pages, so the sum of all web pages' PageRanks will be one.
PageRank or PR(A) can be calculated using a simple iterative algorithm, and corresponds to the principal eigenvector of the normalized link matrix of the web. Also, a PageRank for 26 million web pages can be computed in a few hours on a medium size workstation. There are many other details which are beyond the scope of this paper.

the above was taken from the white paper submitted by the founders of google. found here:
http://infolab.stanford.edu/~backrub/google.html

pagerank is still based around the same formula or a similar one.

In an interview in 2007 (http://www.nytimes.com/2007/06/03/business/yourmoney/03google.html?_r=1), Mr Singhal from Google talked about the 200 signals that google use to rank page, of which pageRank is only one.

It is a very important one, but there are many other factors involved in SEO than pageRank (See the interview for a few pointers towards many more)

Check out the wikipedia page: http://en.wikipedia.org/wiki/Pagerank

probability distributions...eigenvalues...Markov chains...lots of yummy maths to play with.

Even better :)
When I got into SEO I never imaged that my physics degree would come in handy in understanding it

I'm still trying to work out Google's PigeonRank™ system! :|

In my opinion, page rank is a clever marketing tool, invented by google in order to achieve three aims.

1. To generate frequent, heated discussion about google - its a publicity magnet. It also makes people want it, so they concentrate on google more than other s/e's.
2. As a clever weapon to hold over many sites in there attempts to stop the use of alternative advertising methods and drive lots of the competition out of business. For example, do what we say or we will take your page rank away. Dont sell links to people as has been done since the web started, instead write your sites with no-follow, for the search engine (in direct contradiction to googles original ethos of write sites for users not search engines) or use our advertising instead.
3. To provide some input into the ranking of sites.

Thanks For giving ur greatful information about page rank...

It is very helpful information...

in my experience, pagerank isn't anything like as important as it once was. There was a year between the latest toolbar page rank updates which cannot be accurate in this fast moving high tech internet world. If it means anything for placement it is tiny 0.1% or something like that. Do not give it any more thought because i know site with lots of links and a page rank of zero that are on page one of google under hundreds of terms! I wouldn't worry about it!
