Google PageRank

PageRank, created and used by Google, is a measure used to calculate the importance of a website. It is calculated using a number of factors, but is predominantly dependant on quality, incoming links. It should be noted that Google PageRank is applied per page, and not per web domain, and so a popular page on a website can have a higher PageRank then the website's front page.

PageRank is a measure out of ten - with ten being very important, and zero being practically unlinked. A page's PageRank can also be unranked, showing as a grey bar in the Google toolbar. This would generally signify either an unindexed, new webpage, or a banned webpage.

Google PageRank is not the single factor used to return a set of results, and so a zero PageRank webpage can rank higher than a five PageRank webpage. It is simply one of the many factors that Google take into account. PageRank is entirely different to Google TrustRank.
