[Xapian-discuss] 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.

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. Cheers, Olly
