Anyone care to bid on the correct logarithmic base value to use now 5.5, 6.0 etc... are we still assuming 0.85 value passed? I'm working with 6.0 and 0.85 anyone got a better guess?
Nice PR article Compar. Dominic: I doubt if anyone knows the value associated with either the way the toolbar PR numbers are assigned or if the damping factor .85 is still in use, but the numbers in Bobs Spread sheet seem quite good. After Googles last PR update that highest number of links I could find to a PR10 page was between 30 and 60 million. Assuming that the damping factor is .85 and that the average PR of links to pages like Google.com is probably higher than the average of one which the entire PR universe has, the numbers from Bobs chart seem probably as close as were are going to get with the information we have.
The reason why I ask (yes no one knows for sure) is after the last update there were lot of big pr sites that decreased in pr. It would make sense to me that Google is either stopping pr from passing from a ton of sites or the variable 5.5 (if thats what it was - looks good) has perhaps increased, maybe to 5.6 I don't know. If anyone has done a ton of maths to look into this I'm keen to find out.
My site went from a PR 5 to a PR 4. I added 200 pages to the site and 50 back links, yet I still dropped in PR. Does anyone have any ideas as to why? Are the many outbound links off my page the cause? Was it harmfull to change my internal links to add the http://www at the front of them?
The PR of pages in your site, as well as your ranking in search engine results, is dependent not only on factors related to your page but also on factors related to other web pages. Your PR may have dropped due to factors having nothing directly to do with your page or your backlinks... no no
Whatever pr your site has should be focused only on pages you want to rank for key phrases. I made the mistake of trying to spread it out too widely over all the pages. Since I have changed the link stucture on our homeless site to focus the pr only on the pages we are competing with, our serps have really really jumped.
