A BRIEF OVERVIEW OF GOOGLE'S PAGERANK
|
|
Google
PageRank was developed by Google founders Larry Page and Sergey Brin
in the late 1990s in an effort to create a better, more relevant
search engine. PageRank is a "link analysis" algorithm that
analyzes incoming links to a given web site in order to determine a
site's relevancy in relation to the search word or words. The
determined relevancy is expressed in a value of 0 to 10, the higher
the number, the more relevant a given web page is in relation to the
search word or words. In brief, the algorithm that results in
the numerical ranking is a measure of both popularity (the number of
incoming links to a given site) and quality (higher quality incoming
links are given more weight than lesser quality incoming links).
That's a very, very cursory explanation of how PageRank works.
If you want to know more details (and the details are complicated),
you can read the
Wikipedia entry for PageRank.The
bottom line, however, is this: in general, all other things
being equal, the higher a web page's PageRank (assuming the PageRank
is legitimate; see blow for more information on this issue), the
more popular the page within its particular subject niche. A
PageRank of at least 5 is desirable for any given web page, and a
ranking above 6 is difficult to obtain.

PROBLEMS WITH PAGERANK |
| |
| PageRank is widely recognized as
being the best automated way of determining the intrinsic quality of
web pages (and thus sites). However, as with any automated
system, over the years some people have utilized questionable
methods of achieving inflated, or simply false, PageRank rankings
for their web pages and sites. Some details of PageRank
schemes are a bit complicated, but there are a number of ways to
game the system, including the usage of "link farms" (massive
quantities of otherwise useless web pages created for the express
purpose of pointing to a given web page or pages) and "Google
bombing" (creating massive numbers of sites that include the same
anchor text - that is, the visible text in a hyperlink - that biases
Google's algorithms towards a given web page or pages).
There are other ways of gaming Google's PageRank,
but the only thing you really need to know is that trying to
manipulate the manner in which Google analyzes your web site's pages
could get your entire site booted out of Google! Site owners
beware: many Search
Engine Optimization (SEO) services use such unethical practices
in attempt to quickly boost a site's pages, but Google software is
attuned to such methods and will (sooner or later) penalize the use
of shady search engine manipulation tactics.
Finally, in the department of PageRank issues,
more and more individuals are gaming PageRanks on expired pages and
domains and putting their "product" up for sale on eBay and online
forums that specialize in buying and selling sites and domains.
Increasingly, buyers should be very cautious about purchasing web
sites or domains that are advertised with PageRanks. |

ACHIEVING GOOD PAGERANK |
| |
| The basic formula for achieving
good PageRank is simple: create many original content pages for your
site, and work on getting other legitimate, original content sites
with good PageRank to link to your site.
That's it. Sweet and simple. If you
invest the time and effort to create a good, content-rich
web site, and avoid quick PageRank schemes, you will ultimately
be rewarded with a good PageRank for your site.
If you are starting from scratch, give
yourself a year to obtain a PageRank of 4 or 5. Add pages to
the site weekly if not daily, and make sure the pages are original
content that people want to read. And each week locate at
least five other sites to request reciprocal links from; if one of
the five agrees, consider your efforts for that week successful.
Continue this weekly program for one to two years, and you can
expect to achieve good PageRank.
