Hello All, Pls check these calculations: Google Page Rank Calculations The value of how many points that migrate to the recipient page is based on the originating page's points divided by the number of outgoing links on that page. PR goes something like this:- PR0 = 1 page point, PR1 = 8 page points, PR2 = 64 page points, PR3 = 512 page points, PR4 = 4096 page points, PR5 = 32768 page points PR6 = 262144 page points, PR7 = 2,097,152 page points, PR8 = 16,777,216 page points, PR9 = 134,217,728 page points. The above is just a estimate or rough idea for calculation of PR points If you take a link from PR4 and the page has 100 links you will get 4096/100=40.96 points. Let me know your views on this. Thanks
Googlers are beta's , so your 8^x might be true! the original PR algo is published using 6 as base, but they have probably adjusted it along the way.
Don't forget about the dampening factor. Per the original formula it was only 85% of the pages PR that could be passed. We will just leave the 8 multiple to keep things simple. So your example would look more like this: (4096*.85)/100 or 3482/100=34.82 points. Also you have assumed the lowest PR4 possible, it could be as high as a 32767 points on a PR4 page or passing 278.52 points (just under 8x more value). If you get a high PR4 link and a low PR5 link they will pass almost the exact same amount of PR.
Google will just keep us in the dark...if they did tell us the algorithm, they would be out of business! Yahoo! would probably steal it cause they really need it!
