PageRank is a numerical value that Google gives each web page known to the search engine. The
name derives from the fact that PageRank is a system of "rank" in part designed by Larry Page,
one of the founders of Google.


The PageRank of a page is one of th
e many factors that helps determine the location of the page
in search results: higher PageRank = higher page position in Google searches.


It is natural that many webmasters have among its objectives to increase the PageRank of your
site. On the Google si
te there is a brief explanation of how PageRank works.


There are two essential topics: the importance of PageRank for the Google ranking and criteria
used by Google to compute the PageRank of a page.


Pagerank: how much it is really important?


Usually, l
ess than what we think.


The concept of PageRank is designed to get a rough idea of
the degree of "importance" of a web
page. Google is able to assess approximately how a page can be considered authoritative or
popular on the web.


The pages are most imp
ortant in the search results will get an "extra push" that will allow him to
achieve better positions.


PageRank, however, is only one of many, many, parameters taken into account by Google to
decide the position of a page. For this reason, a high PageRank

value does not necessarily
guarantee a better position than a page with low PageRank.


Often, in fact, that pages with low PageRank pages exceed position with a higher PageRank, but
with content (text, HTML tags, links, etc..) more optimized.


For this re
ason, it is recommended interested in the PageRank of pages on your site as if it were
the primary means to achieve good results. On the contrary, it is an element that acquires
importance only if it is accompanied by the presence of other essential featur
es, starting with the
content and the degree of optimization of the pages.


For several years, webmasters have mistakenly believed that meta tags were the main method, if
not the only one to index a site from search engines. The same disinformation that le
d to the
meta tags to become famous so undeservedly, is doing now to get PageRank importance than
that which would be incorrect to attribute.


With the charm of "magic pill" that less
-
informed users are creating around the PageRank, there
is a risk of turn
ing this parameter (albeit important) Google's "new meta tag", a puppet on which
less experienced webmasters will point their strengths , the risk of neglecting all those other
factors taken into account by Google, which can add, are by far the most influe
ntial of PageRank.


In short: it is an important factor, but not the most important or the principal.


How Google calculates the PageRank


Clarified the important (but not sufficient) role in the allocation of the position held PageRank
web pages, now offe
r a simple explanation of how this value is calculated.


The PageRank calculation is performed by applying a mathematical formula which, however
simple, can create extremely complex situations when it is applied to each of the billions of pages
known to Go
ogle.


However, the explanation of this formula beyond the scope of this short article, and referring
readers interested in more mathematical and technical aspects of PageRank to a more in
-
depth
article next production, we try to provide some basic informa
tion about the nature of PageRank
and how to raise and take advantage of the same.


PageRank can be considered a more refined and complex version of the "Link Popularity" (LP).


The LP is one of the many factors that major search engines to give the positi
on to analyze a
web page and coincides with the total number of links pointing to that page. The greater the
number of links pointing to a page, the better the position of that page in search results.


Search engines therefore treat the links as "advice" t
hat a website offers its visitors. A link to
another site, can be considered as an invitation for you to visit the site that benefits from the
link.


It follows that engines are based (in part) on the LP, will give a preference to sites that receive a
numb
er of links than the other. This criterion, however, has several flaws, such as severely
penalizes small sites just born, who need a long time before getting a good amount of links from
other sites.


Google PageRank is also based on the links a page receiv
es and the value of pagerank also rises
with increasing the number of links pointing to the page, but introduces a new element that
minimizes the problems that arose with the links so far Popularity: Instead of taking into account
only the amount of links
received, PageRank also considers the value of PageRank of the pages
that provide links!


In a nutshell this means that (other factors being equal) received a link from a page that has a
high pagerank "worth" more than a link from one page received from th
e value of pagerank low
and contributes most to increasing the value of PageRank of the page that receives the link.


The difference between this method and the "beast" of the LP is considerable: the LP with the
"extra push" derived from links received is
based solely on the number of links, so you see real
benefits from just getting a substantial amount of links coming from other websites. With
PageRank, however, you can get similar benefits (or even better), even getting a few links from
pages if consider
ed "important" to Google, or pages that have a high PageRank value.


The PageRank of a page, therefore, not simply indicates the degree of "popularity" on the web
but goes so far as to indicate a degree of "authority". A web page that receives a few links,

but
from very popular and authoritative sites, it acquires the same authority.
