Page is a not externally linkable

1. A change in the log scale 2. Some downgrading of the value of home pages (with the PR coming to home pages/entry pages distributed to internal pages instead) 3. By association PR is not purely a page issue anymore, G is taking "sites" into account in some way when allocating/distributing PR. 4. A devaluation of DMOZ/Google Directory listings in the calculation of PR (perhaps something to do with the million of DMOZ clones that have sprung up) 5. Some value or penalty for freshness - or lack of it in some categories 6. Devaluing links from some sources - like blogs 7. Devaluing of links from blatant PR sellers (either via a manual block ... or some new way they've found of detecting the blatant PR sellers via algo) And one "pure" conspiracy for good measure.... 8. Throwing in a random obfuscation factor in Toolbar PR that randomly affects some pages and not others (to confuse SEOs) </speculation> [edited by: Macro at 10:10 am (utc) on Oct. 8, 2004]
