 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. Therefore,
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 hundreds
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.
- Although I don't recommend it but some people recommend
it: Do link exchanges.
- 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:
- 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 weigh much.
- Backlink duration: How long was the backlink up? The
more the better.
