Page Rank - Huh?
Calculation:
PR(A) = (1-d) + d(PR(t1)/C(t1) + ... + PR(tn)/C(tn))
What the..!
In simpler terms, Page Rank is a numeric value (0 -10) assigned to a web page. The higher the Page Rank value the higher the calculated importance of the page. Google assigns every indexed page a rank which passes “votes”, “authority” or “trust” to the pages it links to. A page can pass a total of 85% of it rank shared by the pages it links to.
This is a simplification of what is a very complex calculation used by Google. The bottom line is that it made two extremely bright and savvy Stamford University students ultra-rich men. For our purposes we need to understand Page Rank as it relates to your own website and how it ranks in comparison to your competition. It is also equally important to understand the profile of pages linking to you.
When we have an understanding of Page Rank we also can better understand why links matter both qualitative and quantitatively. How many links and of what quality factor into how your site will rank for websites competing for the same keywords. We could also examine the link profile of our websites secondary pages. Second level pages are pages are those linked to from the homepage. In most typical websites the homepage carries the most page rank. We can additionally evaluate how our Page Rank is distributed to our second level pages.
How can I improve my page rank?
- Write a great blog. The more valuable content you write the more page rank each page will add to the collective page rank of your site.
- Get linked to from other ranked sites including QUALITY directories like DMOZ and Yahoo Directory.
- Social Networking helps! Leverage your favorite social media. Sites like MyBlogLog, Twitter, Technorati, Stumbleupon, Del.icio.is, etc.
Other things to keep in mind!
“nofollow” attribute – A HTML link with a nofollow attribute does not pass any Page Rank. Nofollow was created by Google (Matt Cutts) to reduce search engine spam.
Example:
<a href="www.awebsite.com" rel="nofollow">I don’t Trust This Link</a>

Firefox Tip
To see the code of the web page you are browsing in Firefox pulldown from the top menu under View and select Page Source or as a shortcut use <ctrl+U>.
Take another look at your own website and dig deeper into your link profile.
