What exactly is High/Medium/Low PR in Google Webmaster Tools?

[Marvin Hlavac]

Google Webmaster Tools, on the bottom of the Crawl Stats page, shows the distribution of "The PageRank of your pages in Google". There are four categories: High, Medium, Low, and not yet assigned. Does anyone know exactly what the PR difference is between the High, Medium, and Low?

The reason I'm asking is that I just this morning noticed for the first time a narrow line in the "High" area. What is the lowest PR that would fit to the "High" category?

We discussed this question [webmasterworld.com] about a year ago without much conclusion. Your question prompted me to check one "medium PR" site I work with and it is also showing a thin line for "high PR" that I don't remember seeing before. The highest PR for any url at this domain is PR5 and there is only one of those.

Some questions that come up for me: is that thin line just an artifact of the new Webmaster Tools interface? Or did this one PR5 url just gain enough PR to pass some threshold (like maybe 5.5)? Is this report more in present time than the toolbar? I just don't know.

Ted, thanks for pointing me to the earlier discussion on this topic. After reading that thread, and after reading your reply, I suspect, as you suggested, it may just be an artifact of the new Webmaster Tools interface. The line is only 1 pixel thin, and I see the same 1 pixel thin line in the "Not yet assigned" area, even though that area was always empty, too.

A few hours passed, and both of the thin lines, in the "High" and the "Not yet assigned" area, are gone. So it most likely was just a temporary glitch.

Still, the question remains: It would be nice to know the corresponding PR value for high, medium, low. My first guess would be that Low should be 0 - 3, Medium should be 4 - 6, and High should be 7 - 10.

What I have seen from the different websites (ranging from PR NA to PR 9) that I had managed,

PR 0-4 is Low
PR 5-7 is Medium
Pr 8-10 is High

>showing a thin line for "high PR"

I get that also, but only in IE, not happening with FF.

[AnkitMaheshwari]

It is actually a browser compatibility problem of the two browsers. You will always see a 1 pixel green line in IE which would never show in FF. I have seen it in a lot of sites.

HI,
High, Medium, Low page ranks graphs in GWT are based on the page ranks of individual pages in the website,

The distribution of graph may be given by comparing to highest page rank of the website.

for example if we have a web page with 4 a page rank and 100 pages in the website.

1 page will have page rank 4 (high page rank distribution)
15 pages will have medium page rank as 3 (Medium page rank distribution)
70 pages will have low page rank as 1 (Low page rank distribution)
14 pages will No page rank (Not yet assigned distribution)

Is what I am thinking about the High Low medium page rank distribution graphs in GWT is 'correct'

It's a nice theory - but I don't see it working that way in practice. For sites that have a PR4 home page (and that's the highest on the site) I don't see any "high PR" pages at all in WebmasterTools.
