PageRank is a system for ranking web pages
"PageRank relies on the uniquely democratic nature of the web by using its vast link structure as an indicator of an individual page's value. In essence, Google interprets a link from page A to page B as a vote, by page A, for page B."
Links from any page (internal or external) to your site (primarily your homepage) are called backlinks.
Additionally, Google looks at more than the sheer volume of votes, or backlinks, a page receives; it also analyzes the page that casts the vote. Votes cast by pages that are themselves ‘important’ weigh more heavily and help to make other pages ‘important’.
Thus, "important, high-quality sites have a higher PageRank, which Google remembers each time it conducts a search. Of course, important pages mean nothing to you if they don't match your query. So, Google combines PageRank with sophisticated text-matching techniques to find pages that are both important, and relevant to your search."
"Google goes far beyond the number of times a search term appears on a page and examines numerous aspects of the page's content (and the content of the pages linking to it), to determine if it's a good match for your query. "
To find out what your site’s PageRank is, you have to download the Google toolbar. The toolbar gives you an easy way to check your backlinks. This can also be done manually on Google, by typing 'link:www.yoursite.com' (without the ' marks) in the search box.
