I have watched a few videos from Webmasters and Matt Cutts about PageRank and he always says its page specific and that a page can accumilate PR. Thing is I have looked everywhere and on my site, and it seems to be the case that the domain in fact collects the PR. For example, blog.domain.com and domain.com have the same PR. Does anyone else find this? It is good if this is the case, as writing high quality blog content will raise the PR of all website pages, even if the other pages don't have high content on such as landing pages. Does this sound about right?
I would never look at PR as a terms of concrete measurement, I would look more at page authority from something like seomoz. It does accumulate throughout the whole domain, but I would still focus on page specific authority on landing pages, as it is very important for ranking a specific page. Would you ever see something like domain.com/sub-folder/sub-page.php with a PR7 and domain.com with a PR6? I highly doubt it, but using a concrete single digit number means it can range widely from 6 to 7. Hope this helps.
PR can differentiate depending on which page of the site you are on. Analyzing the quality of the content is one thing, but analyzing the PR is all about how the links are dispersed within the site (and the links going into the site from outbound sources, of course). If you have a PR4 home page and link to a few of your top posts from your home page, those pages will probably be PR3. Now assuming you drive a bunch of links to one of these PR3 pages, it is conceivable you can prop it up to PR4 and have it be the same as the home page. But again, this mostly comes down to what PR the outbound links are that are coming in, and then which pages on your site those links are going to. If they all went to the homepage on your site, they would all be dispersed according to your homepage link structure. But if you drive them to other pages on your site, obviously they'll get the PR juice over the home page.
And this is what I thought. But this is what I mean, when I actually look at PR it doesn't seem to work like that. I have a PR add on to for chrome and when I go around websites PR seems to be fixed on every page. I have a forum and even when I go into new child boards it still shows as PR 2 even though there are no posts and no links to those pages. I am just thinking that google may have changes the PR algorithms to work on a domain rather than pages. It does make sence in a way.
Your site having all pages with the same PR is probably an anomaly. Yes, PR is page-specific, not site-specific. Good internal linking will spread PR around a lot within your site. But it would be quite unusual for all pages to have the same PR.
I completely agree with Jim here. Normally I have seen Homepage having higher PR and other pages having lower PR but it is also possible that few pages may have higher PR than home page.
