Xapian discuss - Nov 2010 - Influence of Google PageRank of a page on other pages of same site

Hi,

I know this is the wrong forum for this kind of question and is only
ephemerally related to xapian, but maybe someone here knows and will save me
some digging.

Given a google PR of, say, .15 for page A of site x.com, does google
"radiate"
any of that PR goodness onto any other pages of site x.com?  Irrespective of
whether page A links to any other pages in site x.com.

In other words, if page A has a PR of 0.15, do pages B,C,D...N benefit in any
way? (even if only by a tiny fractional value based on page A's value?
eg, PR(B) += PR(A)/(100*N) where N=number of pages in site x.com).

I'm not talking about the traditional inbound link contributions, etc, only
how -- if at all -- a page influences the importance of other pages in the
same site with it's own PR.

I doubt it, but I can't shake the feeling that if a particular page on a
site
has a non-zero PR, then that somehow must slightly elevate the importance of
the site as a whole -- albeit only by the smallest of measure such that the
site's other pages *might* be considered more relevant.

Regards
Henry

Are you aware there's a published paper describing pagerank in detail?

http://infolab.stanford.edu/~backrub/google.html

However, I doubt Google's ranking is based on pagerank at all by now.
I'm sure they still perform link analysis in some form, but it's bound
to have evolved significantly since pagerank - SEOs have long since
learned how to thoroughly game pagerank itself.
