Phrase selling (or rather key words selling, also known as AddWords) has
no effect on page rank in the search results. It just determines which
adds get served for which types of searches.
People who place the add, select the search key words for which they
want to have their add displayed. Google has an interesting policy
regarding the adds - if not enough people click on an add, they will
stop serving it deciding that it is not relevant to the topics
associated with it.
Open Directory is used in Google Directory as explained at
http://www.google.com/dirhelp.html
"Important" vote basically mean that if you have a site about fly
fishing, a link from another fishing site counts a bit more than a link
from a site on XML.
Here is another interesting place to get some information on what Google
is up to http://google.blogspace.com/ including a link to Google Labs
http://labs.google.com/
Hope this helps,
Irene

Subject: RE: [xml-dev] When Searching With Google
Many thanks for the link, Chris, and welcome to the list.
"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.""
It is difficult to consider a system democratic
if it only counts "important" votes. Republican,
yes, but democratic, no.
Then there is this:
"Google's complex, automated methods make human tampering with our
results extremely difficult. And though we do run relevant ads above and
next to our results, Google does not sell placement within the results
themselves (i.e., no one can buy a higher PageRank)."
That conflicts with two other items I've seen:
1. Phrase selling. How does that work and what does
it do to the returns? Does it only affect ad placement?
2. Use of Open Directory Project. Humans create these.
Since I don't know what use they make of ODP, this one
is a mystery.
"A Google search is an easy, honest and objective way to find
high-quality websites with information relevant to your search."
True, but with ease comes filtering.

I apologize if I am bringing up anything new here. I just joined the
list today, and I have only caught the last few messages in this thread.
In any case, I thought this link might be useful, as it gives a good
abstract as to how Google prioritizes search results.
