Google ranking tips - Page 2
By David Callan
One final tip on page relevancy is the point on having
your keywords and phrases in links which point to your
site. It's a good idea to have the linking text contain
your keywords as Google even says itself in its
description of its Pagerank technology that it analyzes
pages that links come from.
How much keyword laden links matter is anyone's guess. I
have however noticed a lot of sites which give the HTML
code to visitors who want to exchange links do include
keywords in the actual linking area. You should do this
too on your links page, say something like "if you want
to link to this site, please use the following code".
The code would of course have your most important words
in the actual link text and your less important words in
the accompanying description of your site.
Google Pagerank
In the above section of the article you've learned what
areas Google uses and looks at when looking for a
relevant site, but what method does Google use to
determine which site is better, the answer is the
Pagerank system.
Pagerank is as the name suggests a ranking system of
pages. It works on the basis that if a website ABC.COM
has been linked from a website XYZ.COM, abc.com must
have some good content and therefore Google will count
the link from XYZ.COM as a vote for ABC.COM. You can
check your Pagerank on Google by downloading the Google
toolbar from http://toolbar.google.com
The Pagerank™ scale goes from 1 to 10 on the Google
toolbar and from 1 to 7 beside listings in the Google
directory. A less important site is of course a site
with a PR of 1 and a very very important site is a site
with a PR of 7 or 10, in the directory or toolbar
respectively.
The more links or votes a site has the more important it
must be and therefore the higher it will rank for search
words which it is relevant to, right?, WRONG!.
Google does not simply count the number of incoming
links a page has, if that was the case every webmaster
from Iceland to Vietnam would try and exchange links to
every Tom, Dick and Harry website that would let them.
In Googles own words:
"Google looks at more than the sheer volume of votes, or
links a page receives; it also analyzes the page that
casts the vote. Votes cast by pages that are themselves
"important" weigh more heavily and help to make other
pages "important."
Hopefully your beginning to get the idea. The idea is to
have your page linked to by as many high quality and
high pageranked sites as possible. Right? RIGHT and
WRONG.
WRONG BECAUSE, you see the Google Pagerank system also
takes into account the number of links the page that has
linked to you has. The reasoning for this is that a page
X has a certain amount of voting PR, if your site Y is
the only link from that page X, then Google feels
confident that page X thinks your page Y is the best
link it has and will give you more PR. If however page X
has 50 links, page X could think your only the 50th best
link. Hence the more links a page has the less of a PR
boost your site will get.
RIGHT BECAUSE, linking to a site with a 6+ PR will
provide a significant boost to your PR in most cases,
but in cases where the site also links with 100 other
sites the boost will be almost zero. Likewise if a site
has a PR of just 2 but you and only one other site are
linked from it, then the PR boost would be more than the
site with 100 links and a PR of 6.
Google Pagerank formula
It's beginning to come complex isn't it, just wait till
you see this formula. It looks scary for non math's
people.
First let me explain what the damping factor is. The
damping factor is the amount of your PR which you can
actually pass on when you vote / link to another site.
The damping factor is widely known to be .85, this is a
little less then the linking pages own PR.
PR(A) = (1-d) + d(PR(t1)/C(t1) + ... + PR(tn)/C(tn))
In layman's terms PR(A) is the Pagerank boost your page
A will get after being linked from someone else's site
(t1). PR(t1) is the pagerank of the page which links to
you and C(t1) is the amount of total links that (t1)
has. It is important to know that a pages voting power
is only .85 of that pages actual PR and this voting
power gets spread out evenly between all sites it links
to.
Imagine http://www.akamarketing.com was linked by
XYZ.COM's link page which had a PR of 4 and 9 other
links, here's how the formula should look like:
PR(AKA) = (1-.85) + .85*(4/10)
PR(AKA) = .15 + .85*(.4)
PR(AKA) = .15 + .34
PR(AKA) = .49
To sum up my site would get an injection of .49 PR after
being linked from a page with a PR of four and 9 other
links.
Let's say I was linked from a site with a PR of 8,
double the previous example's amount, which had 15 other
links, a total of 16 outbound links, my boost would be:
PR(AKA) = (1-.85) +.85*(8/16)
PR(AKA) = .15 + .85(.5)
PR(AKA) = .15 + .425
PR(AKA) = .575
The above two worked examples show that not only is the
PR of the linking page important but what is also
important is how many other sites are also linked to
from that page.
