I was under the impression that the nofollow still allowed a link to be indexed but that page rank was not assigned -- is this correct?


Purely hypothetical: say that your site has a total PR of 100.

If you have 5 pages and the PR is distributed evenly, each page would be worth 20.
If you increase your site by an additional 5 pages, and the total PR of 100 is distributed evenly amongst the 10 pages, each page would be worth 10 now. By adding additional pages you continue to diluted the total overall PR of all the pages.

Is this hypothetical assumption correct? If yes, could you not use the nofollow coding to restrict PR from being passed onto certain pages (pages that are informational, but don't necessarily need the PR). By restricting the PR from being passed (to say, 5 pages via nofollow) you are again distributing the total PR of 100 to a lower number of pages; thereby helping to keep a higher PR/value to the pages that matter most.



If indeed it example is correct, is it something that is worthwhile to do?
