Google PageRank Explained
by Webmaster Corner
Google PageRank or PR
for short is numeric value assigned by Google to pages
that represents how important a page is. The more important
and known your pages are, the better PR they will get.
PR is a scale from 0 to 10 where 0 is an unknown page
for Google and 10 is the highest PR that can be assigned.
PageRank provides the
basis for all of web search tools. It is always updated
by Google in order to improve it and optimize it.
How is PageRank Calculated?
No one knows for sure how PageRank is currently calculated
by Google (except Google itself). Some speculations about
the algorithm are made by webmasters all of them are based
on the original PageRank published by Google.
In essence, Google interprets a link for page A to page
B as a vote by page A for page B. This means that page
A is considered important (at least by page B).
The more votes (more links) page A gets the higher its
PR will be.
Going into more details
As stated above, the main factor in PR is links (or backlinks
as they are called). But no all links weight the same
when it comes to PR. So an 'important' page linking to
you gives you more PR than a 'less important' one.
There for you should always try to get backlinks from
pages that have a high PR. These will benefit your page
the most.
Another factor in PR propagation is the number of out-links
the 'voting' page have. So a PR4 page with only one out-link
on it might give you more weight than a PR5 page with
100 out-links on it.
An typical example here would be the famous milliondollarhomepage.
This page is PR7 page with hunderds of out-links therefore
its weight is would contribute very little to your page
PR.
How to increase my
PageRank?
Well as you would have probably guessed, PR can be increased
by getting more backlinks for your page. The more backlinks
and the higher quality they are the more your PR will
be.
Here are some tips:
- Submit your site to directories.
- Write important content to your site that would make
people link to you.
- Write articles and distribute them.
- Participate in forums (while adding your signature which
includes a link to your site).
- Buy some links on high PR pages.
When does Google calculate
PRs?
Google calculates pages PRs once every few months, this
is called PR update. After a PR update is done, all pages
are assigned a new PR by Google and you will have this
PR until a new PR update is done.
New sites that were just launched will have a PR of 0
until an update is done by Google so that they are assigned
an appropriate PR.
Other 'possible' factors
considered
The following are some other factors might be considered
by Google for calculating the PR lately:
<ul><li> Site age: The older the better, Google
seems to like old sites.
- Backlink relevancy: Googles seems to be taking into
account how relevant is the page linking to you, if it
is not that relevant, the link won't weight much.
- Backlink duration: How long was the backlink up? The
more the better.
