It gets updated constantly, probably daily. But, the toolbar (what's showed to us) is only updated every few months.
Pagerank is supposedly updated continuously. Visible page rank is updated every three or four months. Shannon
I seriously doubt PageRank is updated continously. There're over 10 billions of pages, trillions of links. PageRank algo needs about 20 iterations to get accurate PR value. We're talking about hundrdes of trillions and zillions of calculation every day or every hour. Google or any company won't spend that kind of resource everyone on something that's not critical. My best guess is PR is updated every month as part of BL update.
I agree with this to a certain extent. Once PR updated during the last update, my traffic tripled from Google. While it may be running in the background of updating, it doesn't appear to me that the search results reflect the Pagerank and what it may currently be set at.
100% agree, and I can thin of relay few other components that can be applicable and relevant, I suggest we start a separate thread to envole more people and their opinons on this matter so by studing each successful expirience we will find the missing puzzles that fit together for this damn Page Positions in the search results here my work http://www.canadaone.org
Really? Well, let me think about it: If I want information about Google, given a choice between someone who works for Google and various forum posters who don't but who like taking wild guesses about what's going on or jumping to conclusions based on superstitious thinking, who shall I listen to?
There are tools on web which can predict page rank, me thinks, it is factor of links a page has, visits a page gets, and its index on search engines RSC www.b2blounge.com
As far as I think, G won't let Matt to disclose each and everything about their methods, processes, formulae, compositions, systems, techniques, inventions, machines, computer programs and projects. That'd be an obvious breach of their NDA (if they do have one). Much would has been decided beforehand as to what he could talk about in the open. Since SEO is all about logic, hypothesis, supposition and conjecture, I would tend to do what works for me. It's a game of trail and error, after all. We think that TITLE tag is one of the most important on page optimization factors. Did G tell us about it? We think that BLs are the most important off page / site optimization factor. Did G tell us they are?
Saying that Matt Cutts doesn't disclose everything about their methods (that's a no brainer) vs. saying he is giving false information are two entirely different things. "I don't think each and everything Matt says is true."
Precisely, mjewel. I was just scrolling down to the Quick Reply box to post that when I found your post. Thanks!
I've also seen pagerank go down with age. One thing to consider: As google's index gets larger and larger, there is (mathematically) a natural tendency for pages to lose pagerank.
I don't think so. Otherwise, why would you have followed it up with this: As mjewel pointed out, these are two different things. My quote from Matt Cutts was in response to the post suggesting that Google can't and doesn't update PR continuously. Either your first post was meant as a response to that or it was meaningless bantering - the fact that you followed up with a second post suggest the first explanation but wasn't really relevant to the issue.
