Just how much does PR count to the weight? Say with all things being equal if my site at the moment was a PR1 and has 500 pages indexed from google and currently has a weight of 3000, then at next PR update if the number of pages remain unchanged (ie.500) and the PR jumps to 5 what impact would that have on weight? 5x3000= 15000?
As I understand it your weight is calculated: pages indexed by google * Home Page PR * no of ads. Except that there is a cap on pages indexed at 4500 and the number of ads isn't straight line such that running 1 ad gives a multiplier of 1 but running 5 ads gives a multiplier of 3.
My homepage is PR5 but several sub-pages are PR6. Does it take into account the whole sites PR or just the HP?
