The Layman's Guide To The Google PageRank Algorithm

Let me ask you: If you have a certain idea or topic in
mind, and you wish to find out more about this topic, what
do you do? Ten years ago you would probably have gone to
the library, but today... You GOOGLE IT!

If you take anybody currently living in the modern world,
chances are that is what they will tell you. Google is
King! Over the course of just a few years, Google has gone
from a couple of smart guys at Stanford University with the
revolutionary idea of making the entire internet available
from their desktop, to being the undisputed gatekeeper to
nearly every single portion of humanity's collective
knowledge.

The Google search engine has in fact become so popular and
proliferous that the word 'google' itself has now become a
verb! (As in, if you want to find out more about a certain
person, you just google them.)

Every time you do a search, you will see the term or phrase
that you searched at the top, followed by about ten
webpages that Google thinks are most relevant to your term.
Since there are literally tens of millions of Google
searches every single day, it is not a great leap to think
that the websites that manage to get their ranking very
high in Google will get ALOT of free visitors and traffic.

But what is it exactly that determines which websites get
listed in the top ten listings? Well, the system that is
behind every single search result that you see is called
the PageRank system, named after its creator and co-founder
of Google, Larry Page.

Before the PageRank system, there did exist some other
methodologies for determining web search relevance and
delivering accurate results, but none of them were as
robust, accurate, democratic, or resistant to human error
as PageRank.

-What Puts PageRank in A League of Its Own-

There are basically two major ideas behind the PageRank
system that have made it so revolutionary:

First, the PageRank system is rather democratic in nature
because every time one website (we will call it site A)
links to some different website (we will call it site B),
that link is considered to be a 'vote' by site A that site
B has good information, or for some reason is worthy of
being viewed and read. This concept of the democratic
nature of the links found all over the internet is a vital
main idea behind the PR system.

Second (and this is the part that really put PageRank on
the level), NOT ALL LINKS ARE CREATED EQUAL!

That is to say that if you have two links coming to your
website, one from Forbes.com and another from some
backwater, fly-by-night dot com, these two links will not
be treated equally.

So what does this mean for the question of how did the
highest ranked sites get where they are? They have been
around for long enough to have numerous popular sites link
to them, they have valuable, relevant, dynamic content, and
chances are that they probably link to other related
websites.

Another vital (but not so revolutionary) mechanism behind
determining which webpages are displayed for certain
keywords is an advanced text-matching system. Google's
text-matching system is able to deliver highly relevant
webpages because of the vast computing power behind the
Google search engine itself.

-Technical Explanation of a Website's PageRank-

This following part is a technical explanation for those
who want to further understand the nature of the PageRank
algorithm. If you are only interested in learning how to
improve your own site's PR, then feel free to skip to the
next section.

The PageRank system gives every webpage a numerical value
that falls between the range of 1-10. It will help if you
can remember from your math class what a logarithm is,
because the assignment of a certain PR number is
logarithmic in nature, similar to the Richter scale of
measuring earthquakes.

This is important to understand, especially if you want to
increase your own PageRank. This means that a PR7 site has
ten times the value of a PR6 site, and 100 times the value
of a PR5 site. So this would mean (not exactly but
approximately) that an incoming link from a PR6 site would
give you as much value as about a few dozen PR4 sites.
Notice that a PR6 incoming link will NOT give the value of
100 PR4 links, because PageRank is concerned with the
quantity of incoming links as well as how important they
are.

-Tips For Improving The PR of Your Site or Blog-

Try to create content that is valuable, funny, or for some
reason really makes people want to link to it. This will
naturally increase your number of incoming links, thereby
increasing your PageRank.

A 'link farm' is a website that has hundreds or thousands
of incoming and outgoing links. Sites like this can
actively inflate PageRank to make a site seem more relevant
than it actually is, so Google will 'punish' websites
associated with link farms by bringing them down in the
search rankings.

Do not worry or feel like your site or blog is not good
enough if after just a few months or so you do not have a
high PageRank and are not listed very high in the search
results. It takes time to build PR, so the better your
content and the longer you have been online, the better
chance you have at naturally gaining a higher PR.

Find a few quality websites or blogs out there that are
related to your own, and see if you can contact the owner
to have him/her link to your site in exchange for you
linking to theirs. This is called 'link exchanging,' and if
you do it to much then Google may 'punish' you becase this
is another way of inflating PR, but exchanging links with a
few quality sites will help you.

One last thing, and this has been stressed throughout the
article, there really is a single golden rule that you can
apply to boost your PageRank: create MASSIVELY VALUABLE
information and content that people will naturally want to
link to on their own, and you are set.
