Do links from PR 0 pages help? I mean pages that are indexed in Google, or in yahoo site explorer inbound links.
This question in regards to increasing PR.
Given also that the links from the PR 0 are one way links.
Also, regarding being listed in PR 0 pages on directories... The main page of the directories themselves could be PR 5 to PR 1, but the pages inside, on which the site is posted, is PR 0, or Google toolbar says there's no PageRank information.
What are you opinions about this?
