"Page Rank," sometimes abbreviated PR, was developed by Google's founders Larry Page and Sergey Brin. Here is how Google describes the "Page Rank" system: Page Rank 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. But, Google looks at more than the sheer volume of votes, or links 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." Important, high-quality sites receive a higher Page Rank, 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 Page Rank 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 term appears on a page and examines all 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. Page Rank is rated on a scale of PR-0 to PR-10. A site with a ranking of PR-10 is much higher than one rated PR-0. When a site has a high page ranking, there will be more opportunities for search engine users to locate and view the site. Thus, more traffic will be routed to that site because it is viewed by the web community as a valuable resource.
What Does This Mean For You?
Well, it all goes back to link pop... If you have a ton of quality, relevant, incoming one-way links to your website, your Google PR is going to shoot through the roof!
A high Google PR means more exposure for you. Heightened exposure leads to more visitors, and more visitors basically means bigger sales. Simple enough.
Ask any successful web developer how to inexpensively gain quality non-reciprocal links and they'll tell you: Find and exchange links with as many websites that relate to your own and also submit to as many directories as you can.
Finding websites to exchange links with can be a very time consuming process if done manually but there are now many software titles on the internet that will make the job a lot simpler and save you loads of time as well and one of the best is called Backlink Submitter and it can be found at http://www.backlinksubmitter.com
Don't forget about directories, they are viewed by web users as a quick and easy way to find valuable resources tailored specifically to their search. As a result of directories' popularity, a submission to a lot of them will generate a great deal of targeted traffic.
There's only one problem: The directory submission process is long and tedious. Some directories, such as Yahoo! Directory, cost up to $300 for one submission. If you're operating on a tight budget, you are better off spreading your money over many smaller directory submissions. Unfortunately, that can take a lot of time.
