Page Rank on Moz compared to Ahrefs

So there seems to be a huge philosophical difference behind how Moz and Ahrefs calculates page rank (PA).

On Moz, PA is very dependent on a site's DA. For instance, any new page or page with no backlinks for a 90DA site on Moz will have around 40PA. However, if a site has around 40 DA, any new page or page with no backlinks will have around 15PA PA. Now if one were to decide to get tons of backlinks to this 40 DA/15PA page, that will raise the PA of the page slightly, but it will likely never go beyond 40PA....which hints that one would rather acquire a backlink from a page on a high DA site even if that page has 0 links back to it as opposed to a backlink from a page on a low DA site with many, many backlinks to it.

This is very different from how Ahrefs calculates PA. For Ahrefs, the PA of any new page or page with no backlinks to it will have a PA of around 8-10ish....no matter what the DA of the site is. When a page from a 40DA site begins acquiring a few links to it, it will quickly acquire a higher PA than a page from a 90DA site with no links to it.

The big difference here is that for Ahrefs, PA for a given page is far more dependent on how many inbound links that page has. On the other hand, for Moz, PA for a given page is far more dependent on the DA of the site that page is on. If we were to trust Moz's PA calculations, SEOrs should emphasize getting links from high DA sites....whereas if we were to trust Ahref's PA calculations, SEOrs should focus less on that and more on building links to whatever page they want to rank up (even if that page is on a low DA site).

So what do you guys think? Do you agree more with Moz or Ahref's valuation of PA. Is PA of a page more dependent on the DA or more dependent on it's total inbound links?

Rankings fluctuating by around 10 pages between night and day

Hi all, I'm experiencing something very odd with my website ranking at the moment. My homepage is fluctuating in rank for my main keyword by 10 pages every day and night. So, during the day i am on page 14, 15 or 16 for my main keyword yet by night i am on page 5 or 6. This trend has continued for the past 7 days now and i can't quite understand why this is. I'm using pagewash dot net to carry out manual searches and a ranking tool - both of which produce exactly the same result. Does anyone have any experience of this or why this is happening? My domain is around 8 years old and has around 50,000 pages. Any pointers would be greatly appreciated.

Does google index non-public pages ie. members logged in page

hi, I was trying to locate resources on the topics regarding how much the google bot indexes in order to qualify a 'good' site on their engine. For example, our site has many pages that are associated with logged in users and not available to the public until they acquire a login username and password. Although those pages show up in google analytics, they should not be made public in the google index which is what happens. In light of Google trying to qualify a site according to how 'engaged' a user is on the site, I would feel that the activities on those member pages are very important. Can anyone offer suggestions on how Google treats those pages since we are planning to do further SEO optimization of those pages. Thanks

Rankings drop, but only one term

Has anyone experienced a significant drop on just one term? I have about 10 terms that I am constantly monitoring and 9 out of 10 are unchanged or even improved, but 1 term was #1 and is now #11. Curious if anyone has experienced anything similar. I originally thought it was "Panda", but why wouldn't all my terms be affected??
