Getting Blacklisted on Google is a death sentence. This article covers good practises and what to avoid. Pagerank is explained in laymans terms and links to full page rank definitions are included.
Blacklisted on Google

ust to clarify, being blacklisted means your pages
will be demoted (or removed) from Google's search index. However this is not
going to happen to your site unless you violate one of their principles.
Google are pretty transparent about what they expect from a webmaster
and the
webmaster guidelines should be taken seriously.
Top of their list of no-nos is cloaking (i.e. making a page look one way to spiders but another to humans),
or any other artificial means of boosting a search ranking. A simpler way of looking at it is - write for
people to read.
Google can also demote your page ranking
if you link to a linkfarm from your site, or
otherwise put hidden links in your pages.
They are not happy about people using Search engine rank check
programs. However these programs can be found on search engine results. I just
did a search on "rank checking program" and a number of such programs appeared.
It looks like overuse will get you in trouble. Checking more than once a week is
a bit pointless in my opinion as a glance at your log files will reveal which search
engine keywords are bringing in the traffic.
Blatant missuse of googles policys will get you barred. Like BMW in germany
who repeated keywords and cloaked pages see
Google blacklists BMW.de.
Google has an advertising program
called Adwords, and one of their policies
is that they do
not allow sites that use popup windows to
participate in this program.

Linking and PageRank
Using redirection to track links
that visitors click is common.
As with affiliate programs, these links don't
count to benefit your site in link analysis
systems. Google however, does take redirection
into account.
The major search engines
link analysis systems make almost exclusive use of
inbound links. They do not look at your outbound
links to determine whether your page should rank
well. However internal links can boost a pages importance
within your site.
A really good diagram to show how page rank works is found in this
wikipedia
pagerank definition. However the white paper from Ian Rogers
contains the most complete
pagerank definition with lots
of examples. Expect to read and re-read it many times though, its complex!
"The major search engines link analysis systems make almost exclusive use of inbound links."
A quick definition of internal linking follows:-
With Google, pages with many outbound links will not be given the same importance to a page with fewer links. To clarify, take an example where Google rates two pages as equal. The first page has two outbound links, the second page has ten. Each of the second page's links would only be worth 2/10ths of the first page.
