How does Google decide a Web Page Rank?
Google Page rank is based on back links. Back links are links pointing
to your website from another website. The more back links you have
the higher your PR will be.
In short a Link is a “vote”, by all the other pages on the Web, about
how important a page is. A link to a page counts as a vote of support.
If there’s no link there’s no support.
Links from and to high quality and related sites have an impact on
Page Rank. If pages linking to you have a high Page Rank then your
page gains some part of their reputation.
While assigning PageRank, Google considers site age, back link
relevancy and back link duration.
Page Rank does not rank web sites as a whole, but is determined for
each page individually.
Multiple votes to one link from the same page cost as much as a single
Bad incoming links have negative impact on Page Rank.
Each inbound link is important to the overall total. Except from
banned sites, which harm.
