I’ve written in the past about the interpretation of the PageRank probability distribution as an economic utility function. Recall that one interpretation is PageRank(url) = probability that a random surfer arrives at the url. This can be used to estimating monetary value for advertising on the page, because it is correlated to the number of impressions.

Now it turns out that PageRank has another monetary value – the estimation of monetary value for buying stolen login usernames and passwords. This is further evidence of the concept of PageRank as representing a measure of monetary value.
