Is There a Difference Between N/A Page Rank and 0?

From my experience; (and let me preface this by saying I haven't verified this); a 0 PR tends to mean you've been indexed and there's a possibility of getting some PR. A N/A tends to mean you've not been indexed, yet.

Again, not verified; just been my experience. Your experiences may vary.

PR N/A: Your site is new
PR 0: Your site sucks

Just joking lol

I agree.

PR: N/A could mean a that your site is new, not indexed, rank can't be calculated or needs to be recalculated or it has been penalized or banned.

PR: 0 means it has been indexed but google thinks the site doesn't have enough quality backlinks or it has low quality contents/pages.

Google calculates page ranks quarterly (or more) so you could still improve your PR.

While an unindexed page will report a PR N/A value, PR N/A is not an indication that the page is unindexed or penalized.

PR N/A : at the time that you are checking the page rank there was no page rank reported. (i.e., PR = Null)

Either, the page (not site) you are checking has been created since the last public PR update and it actually holds PR value but public PR records have not been updated to reflect the change. All pages, regardless of their actual PR value will hold a PR N/A value until the next public PR update. your page could actually be a PR 3 but still show PR N/A because public records have not been updated

Or, there is are no other pages with enough PR linking to this page to pass sufficient PR to the page so that it can gain its own PR value. In this case the public rank has been recalculated since and still no page rank has been assigned.

PR 0 : The page existed prior to the last public PR update. It does not mean that the page completely lacks page rank, it means that the page rank was not enough to reach PR 1 (e.g., PR = 0.5). between 0 - 1 still have value unlike n/a which has no value at all

This is my take on it. I might not be 100% but i bet i am very close

not necessarily.

obviously if the page has no juice to pass, then it will pass no juice. however, it will still count as a backlink and can be seen as a "vote" toward your page. Although, it will not help to increase your page's PR

on the other hand, if the page is only PR N/A because it is new and was not around durring the last PR update, then it may have plenty of juice to pass.

You have to understand what Toolbar PR represents to understand the difference. When you look at the Toolbar PR you are looking at history. It only gets updated once every few months.

Toolbar n/a typically means that the LAST time a snapshot was taken of the Google index so that they could map each URL's actual PageRank to the 0-10 Toolbar PR and publish it as a toolbar update, that the URL in question was NOT in their index. But it may very well be indexed now. It might even have an actual PR value of PR2 or PR3 by now but is still showing n/a in the toolbar.

PR0 typically means that your URL was indexed the last time a Toolbar PR update was made and published. Your URL had PageRank when the last toolbar update was created and published, but it just did not have enough actual PR to be considered a PR1. Again, just because the Toolbar PR shows PR0 now does not mean that the actual PR (the one that counts, the one that is constantly updated, the one that you never know the true value of) is still PR0.

If your URL was showing a higher PR (like PR4) and suddenly drops to PR0 or n/a, both of these can be a sign of a penalty, but they do not necessarily mean you are penalized.

I have seen PR6 pages drop to PR1, but the organic traffic (hundreds of thousands of visits per month) remain the same. Then suddenly a few weeks later it pops back up to PR6. So when your PR suddenly drops to PR0 or n/a, it doesn't always indicate a penalty.

It's strange though how the N/A ranges in terms of the articles it's showing up on. I've got articles from 2 years ago showing N/A so it's not an issue with it being too new, granted I haven't built any backlinks to most of those articles.

A really good example is articles I wrote maybe in December of last year and even created a handful of backlinks to so Google has no reason to not know they're there, yet they're listed N/A. Then I've got other articles written around the exact same time, same niche, same everything with the same backlinks and they're showing PR 1 or 2.

There just doesn't seem to be any rhyme nor reason for why some of these are showing N/A. I can't see being penalized when I don't mess with the equation at all between so many articles.
