Jim Gaudet, normally we do a new push of toolbar PageRanks every 3-4 months.
So
normally they do a new push of toolbar PageRank
every 3-4 months and not exacty every third month.
Good to know.
So hopefully it will reflect
stable semantic IBL's links (Google's measure of the importance of (votes for) a page).
My own comment:
"In my opinion, toolbar pagerank is a measuere of stable semantic IBL's, in other words, Google's relatively stable measure of the importance of a page, a reflection or mirror of what I call Google's adaptive inverted link matrix model of the web, real meaningful citations or votes if you prefer a non mathematical language. I personally do not know of a better software (BOT) model in 2008.
It is the outcome of a complex system like temperature is the outcome of a partly known high dimensional system. In a sense, a projection from that system to the thermometer or the temperature metric represented by a single number.
Toolbar pagerank should not be confused with SERP position that so many webmasters do. Neither should it be confused with directory or internal PageRank that may fluctuate from day to day".
