What is PageRank?
PageRank is named after Larry Page one of the two co-founders of Google.
PageRank is the number and importance of links pointing to you.
The value of each link depends on its PageRank and the number of outgoing links. (Pr/L)
In practice, if it just worked like this, PageRank would just keep cycling around forever and mathematically speaking the world would blow up.
So there is an additional thing which is that PageRank kind of evaporates.
A little bit of it decays every time it goes across a link. (@8minutes and 15 seconds). (Author comment – this is like a Google tax – Google is removing a little of the value of each link.
For those involved in reciprocal linking it means that if each link used to reciprocate have equal value, both websites lose a little link value from their websites.

Matt makes the important point that if your website is to grow and increase its reputation and ranking, it must do so slowly and build up – just like in the Japanese game of Katamari
PageRank and the Google Algorithm
“You want the answer, not trillions of webpages. Algorithms are computer programs that look for clues to give you back exactly what you want.
For a typical query, there are thousands, if not millions, of webpages with helpful information.
Algorithms are the computer processes and formulas that take your questions and turn them into answers.
Today Google’s algorithms rely on more than 200 unique signals or “clues” that make it possible to guess what you might really be looking for.
These signals include things like the terms on websites, the freshness of content, your region and PageRank.”
