Google Page Rank

Google Page RankGoogle Page Rank is a number between 1 to 10 given to a web page which shows the importance of that page. It is also calculated for the whole site. Thus your site is given a Page Rank and each page within your site is also given a Rank. It depends on the number and quality of other pages linking to your page.

Google Explained About Page Rank

Google interprets a link from page A to page B as a vote, by page A, for page B. Votes cast by pages that are themselves "important" weigh more heavily and help to make other pages "important."
In other words, Google conducts “elections” in which each web page casts votes for web pages with hyperlinks to those pages. But unlike a democracy a page can have more than one vote and links from pages with high PageRank are given more weight (according to their ranking) and thus help to improve the targets’ PageRank.

Internal linking

As well as the external links, Internal linking also plays a factor in the Page Rank of the pages within a site. It is most common to see the homepage, index.htm, to have the highest PR of the website.
When you look at most sites, you’ll find their main index page has the highest rank out of all indexed pages for that site. As you step down the directory structure to secondary links and below, the page rank will usually decrease. So, you could have a PR of 6 on your main page, 5 on your secondary pages, and so on.

External Linking

External linking is the largest factor in determining Page Rank, and is the place where you have the least control. There is no way to force another web master to link to your site, especially when they already have a high Page Rank. For this reason and many more, increasing your Page Rank is difficult, but important however.
The actual amount of effect that Google's Page Rank has on the ranking of a website. The higher a web page's Page Rank, the more frequently it will be crawled and refreshed. While in most cases, a higher PR will accompany a higher-ranking site; it is not always the case.
