| Understanding
and Building Google PageRank
Google, the search engine that has evolved into the focus
of all search engine optimization professionals has in the
past half of a year introduced the Page Rank feature. This
is nothing new to the search engine optimization industry,
and probably nothing new to most of our readers as we have
mentioned it in previous search engine articles.
For those who are not familiar with Google's Page Rank,
which is commonly known as PR, is Google's calculation or
score of a web page based on external and internal linking
of a site, as well as on-page criteria of the web page being
linked to as well as the web page being linked from. The
Page Rank calculation is much more detailed and complex,
and we go into the calculation in more detail later in the
tutorial, as well point out other places that you can read
up on how Google calculates a web page's PR.
Before you can begin to develop or increase the PageRank
of your web site and individual web pages, you will need
to evaluate what the PageRank of your site's pages is currently.
To view the PR of your site you will need to download the
Google Toolbar.
PageRank is in some ways related to link popularity, but
the calculation is dependent on the quality and strength
of the links, not just the number of links. So, how does
one go about building and increasing their Page Rank. It
is not as difficult as some may think.
Google
searches more sites more quickly, delivering the
most relevant results.
Introduction
Google runs on a unique combination of advanced hardware
and software. The speed you experience can be attributed
in part to the efficiency of our search algorithm and partly
to the thousands of low cost PC's we've networked together
to create a super fast search engine.
The heart of our software is PageRank™, a system for
ranking web pages developed by our founders Larry Page and
Sergey Brin at Stanford University. And while we have dozens
of engineers working to improve every aspect of Google on
a daily basis, PageRank continues to provide the basis for
all of our web search tools.
PageRank Explained
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. 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 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 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.
Integrity
Google's complex, automated methods make human tampering
with our results extremely difficult. And though we do run
relevant ads above and next to our results, Google does
not sell placement within the results themselves (i.e.,
no one can buy a higher PageRank). A Google search is an
easy, honest and objective way to find high-quality websites
with information relevant to your search.
