Citat:
By not making public the real PageRank value, Google can ensure that SEOs won’t reverse engineer their algorithm completely. That would be catastrophic for their search engine as the results would be easily manipulated once people would figure out what works and what doesn’t just by trying things out, observing the reaction of the PageRank value in their browser.
Toolbar PageRank is being updated infrequently. Again, that is deliberate so user’s wouldn’t be easily aware of the current PageRank on a given page. Again, that is for Google’s own security against reverse engineering.
A typical toolbar PageRank value corresponds to a wide range of real values. That means that not all toolbar PageRank of 3 sites have the same PageRank value and these values can vary greatly.
