Sorry if this question sounds noobish to you Let's say my site www.mysite.com has a page rank of 3 Will each page of the site have the same page rank ? For example will www.mysite.com/page1.html have the same pagerank with www.mysite.com/page2.html ? And also if someone links to a certain page of my site like www.mysite.com/page3.html ,will that increase the pagerank of the other pages as well?? thanks in advance !
Each page is assigned a separate PR. Your site PR is the PR of your home page: http://www.yoursite.com/
Google sitemaps feature lets you know the highest ranking page... but not the actual rank. PR is 'only' an estimate afterall. From what I've read, though, generally as you decrease in root structure from the homepage... subfolders tend to loose a little pagerank.
so would a hign ranking index page help all the other pages increase their PR since they would be linked from a high ranking page?
Yes it would provided wach page were linked together. Page Rank is no longer the force it once was in Google's ranking algorihm however.
No if your other pages have got a link from the main page only then they would have a 1 PR less then that of the main page.
