I dedicated the last 2 hours to understanding how Google can benefit from a system that is able to track traffic worldwide. Under benefit, I mean to improve their ranking algorithm. There is a major flaw in Brin's original algorithm, roughly it tries to estimate the probability of a document 'd' given a query 'q', e.q. p(d|q). The higher is p(d|q) the higher you will rank. Whoever familiar with Bayes theory will know that:
The probability of document p(d) is what we know as page rank. Its calculated using pairwise probabilities p(document1|document2), e.q. the probability of landing on document1 given you're now on document2. Lately, Google seem to give less weight to that component because its estimated using backlinks, and backlinks is our core business here on BHW (the flaw I'm talking about)
Imagine, what would happen if Google was able to estimate that component using traffic flow. Thats a game change, and if I were Google thats where I would aim.
Google analytics, Chrome, any buttons you install can do that.
Code:
p(d|q) ~ p(q|d) * p(d)
The probability of document p(d) is what we know as page rank. Its calculated using pairwise probabilities p(document1|document2), e.q. the probability of landing on document1 given you're now on document2. Lately, Google seem to give less weight to that component because its estimated using backlinks, and backlinks is our core business here on BHW (the flaw I'm talking about)
