i am a bit confused about How a site sub-pages PR are calculated .. Some sites has their sub-pages with same PR as the main page .. for me , most of my sites have sub-pages PR 0 , while the main page has 4 or 3 and my main pages are linked to the sub-pages . can this be explained plz ..
..."a few PR updates"... Really? I thought internal pages usually got PR on the first update if they are linked...
Really depends on when the pages are placed, linking structure, and number of internal links. Since google takes a snapshot of the site, it is most likely not on the day that the PR update is done. Index external links 1-3 weeks Index and cache internal page 1-3 weeks So I think we are both correct on this one. I dont have any firm examples, but I do see on a lot of my sites, that if the page hasn't been indexed for a while, they dont show PR on the update.
It depends on what kind of a subpage it is. Static pages with a link from the main page are more likely to receive PR, as they stay the same over time.
Content has nothing to do with PR IMO, I have blank pages with PR5. It has to do the age of the page, the links, and age of links to the page.
PR gets passed through links, it's simple. You don't have to have external links to your subpages, a link from a page on your site with PR will pass PR to that page. The more links on that page, the less PR that gets passed through them. A typical PR 4 site without an insane amount of links should get a PR3 pages for those links, but like I said that depends on the number of links. Age of links have nothing to do with PR, and more to do with serps. Remember toolbar only gets updated every few months, and if that page was created after the last update then your not going to show any PR until the next update.
Agreed, but /static-page.html is more likely to a a decent PR than /2005/12/google-trivia.html (like a post on a blog), as it's not just one of many posts with individual URL, but a page that stays the same over time. My point is that each and every dynamic page has its own PR and doesn't share PR, as in every post having the same PR because they're shown on the post.php page.
They do require age to get value, but that value is for search engine rankings. PR is simply based on pages linking to another, with no other variables.
I agree except for querystring URL's like: /test.pgp?ID=10&page=new I had a site that had a page say /order.php which was PR4, when I added 2 new pages with a querystring, they instantly showed with PR3. Not saying this is a good way, as we all know at some point the SE's will get bored of indexing querystring pages.
A url like that might not get indexed, especially if it's many links from the homepage and no other links going to it. But, with that said, if it get's indexed then it gets and passes PR.
I'm not saying it doesn't, but unless you get inbound links to every single post or dynamic page, it's unlikely you'll achieve decent PR just by having the paged linked to from the main page a few days on all of them, as it's pushed of the page by new posts (in the case of a blog or news site).
