How is Moz Page Authority Calculated?
-
Can anyone refer me to a document that explains the measures that go into the calculation of Moz Page Authority? I'm chiefly interested in what counts and what doesn't -- follow links, no-follow links, internal and external, what (if any) on-site factors, etc.
-
So it sounds like it's intended as a proxy for Google Pagerank.

Page Authority higher on my old (redirected) domain than new domain?
Hi everyone. I moved the domain my blog was on about 18 months ago, and it's ranking in Google never recovered. I've noticed in the 'Inbound Links' tool that my old domain (jamescrowley.co.uk) shows a page authority of 26, while my new domain (jamescrowley.net) shows a page authority of 15. Any idea why that would be? 301 redirects have been in place for the whole 18 months, so I'd have thought the authority would have been 'passed on' by now? Many thanks James

Subdomain and nofollow backlinks are used to calculate the domain authority?
Greetings, I have a couple of questions about domain authority. 1 - The backlinks that come from different subdomains count several times or only once coming from the same domain? 2 - The nofollow backlinks are used to calculate the domain authority? Thank you.

My company has about 70 live pages. Moz crawled 6k. Why?
My company has about 70 live, published pages on our website, which is managed through HubSpot. When Moz crawled the URL, it found 6K+. I noticed several were URLs with a campaign tag. Is this normal? It seems excessive to me. If there's a problem, how do I fix it?

Can improving page authority on all pages help overall domain auth?
Our website is made up of approx 4000 pages - some of which are old pages with a pa of 1. I am removing these pages (ensuring they don't have links etc). Can removing so many low scoring and useless pages impact on domain authority. Our DA jumped 4 points and i wondered if this was helping Example 4000 pages in total 2500 have PA 1 - these get removed will it look better for DA that overall there are now no pages where PA =1 and the site now contains higher PA pages only?

"Https://" version of my home page has PA of 39, while the "https://www" version has a PA of 43?
Why would the "https://" version of my home page have a PA of 39, while the "https://www" version has a PA of 43? Is Google seeing this page as two different pages? I'm seeing different linking domains to each. What can I do to unify the two? There is already a 301 redirect in place.

Why is Moz not crawling my backlinks
Hi my website www.dealwithautism.com is 3 months old and has been on DA 1 and PA1 ever since, even though the site is actively developed with quality content (a couple of posts already have 1k+ fb likes acquired editorially, while that doesnt necessarily improve SERP, it sure tells you that the post is engaging). In contrast another site of mine, www.deckmymac.com which is hardly ever managed, not have more than 15 posts and just 1 backlink, has DA 14. Running an on page analysis on www.dealwithautism.com I observed that Moz has not identified any backlinks nor social signals (except G+). However, according to Webmasters, I have 57 links, 51 of them to the root. Even Majestic is able to report 32+ backlinks. So what am I missing? Certainly, at this stage my website doesn't deserve DA 1, or does it?

How Is a Page Crawled by Moz When Moz Says 'No Links'?
As above, really. I've crawled a new client's site to find the Moz crawler has identified a handful of 404 errors. The Moz crawler says these pages have '0 linking domains', and OSE has no data for these pages. So how are these pages being crawled by Moz and what should I advise my client?
