I'm sorry but I still don't understand everything I can't give URL coz we are buying that company So... imagine a site with a PR6. I was thinking a range of 5000 BL with google and some 3000 pages indexed. I went to my favorite quick checker and I found that Google shows 19 BL same kind on number for other engines. Using my API, did the same verification... 19 BL. Ok, next thinking was these BL are from PR9 sites... nop the highest is a PR4 and looks like a link farm. So may be there are tons of pages... according to my favorite tools there are 29 pages indexed by google... went to G-metrics... same number 29... Talked to their web guy..., the site is PR6 since very long, never added or removed pages, nor played with BL - the company did not spend much time or money on SEO. All they have is a monthly paid submission with Microsoft bCentral. So, I'm lost... Can you help me to understand why google is giving a PR6 to all 29 pages but one sub page which is PR7? Thank you Pierre
Google knows about other backlinks besides the 19 you see, which give them reason to assign a higher PR.
I think it's not quite easy to figure out how pagerank changes. for example; links given from rival sites are more valuable.
The page with the PR7 probably has more links to it then the other pages. PR is dealt with on a per page basis, not a per site basis
Because that's making the job harder then it needs to be. Check out http://www.marketleap.com/publinkpop/default.htm
I used marketleap too and this PR7 report no link at all. I looked at the log files and there no referrer for that page... I don't where google messed up. I'll see during the next PR update how google ranks it and let you know. As soon as the purchase is finalized, I'll publish the URL so gurus will be able to put the light on this mistery
