What is the logarithmic scale used for domain authority?
-
I want to quantify how much better a score of 80 is compared to 60.
Or 60 compared to 30 etc....
What is the logarithm base?
Thanks,
Rik

It turns out to be a bit complicated, since DA/PA are based on a machine-learning algorithm. Dr. Matt Peters, our resident data scientist, answered a similar question here:

Moz Domain Authority [Megathread]
Hey Moz Community, We've noticed that there are questions about Domain Authority, what it is, and how to positively impact it. We're here to answer your questions! For a full overview, please see our help hub article here: https://moz.com/learn/seo/domain-authority First, it's important to keep in mind that Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how likely a website is to rank in search engine result pages (SERPs). It is not a Google ranking factor. Domain Authority scores range from one to 100, with higher scores corresponding to a greater likelihood of ranking. Since DA is based on machine learning calculations, your site's score will often fluctuate as more, fewer, or different data points become available and are incorporated into those calculations. For instance, if facebook.com were to acquire a billion new links, every other site’s DA would drop relative to Facebook’s. Because more established and authoritative domains like Facebook will have increasingly larger link profiles, they take up more of the high-DA slots, leaving less room at the higher end of the scale for other domains with less robust link profiles. Therefore, it's significantly easier to grow your score from 20 to 30 than it is to grow it from 70 to 80. For this reason, it’s important to use Domain Authority as a comparative metric rather than an absolute one. The best way to influence your DA is to improve your overall site health with a focus on the quality and quantity of external links pointing to your site. Check out this video for more details on how to impact DA Happy analyzing!

Why my Domain Authority (DA) is Decreased from 21 to 19?
Hello, I would like to know how the changes in domain authority is counted by MOZ? Domain Authority for my this domain http://www.grandcrayon.ca/ was 21 and it is decreased to 19 in last week. I have checked the moz report and it shows DA as 19. We already have grandcrayon.ca and we recently redirected our .com domain (http://www.grandcrayon.com also to .ca so all the back links of .com are now showing in webmaster for .ca. So i would like to know the reason behind decrement in DA and is there any connection with redirection of .com domain? How can i increase DA for my website?

Canonical URLs all show trailing slash on main site pages - using Yoast SEO for Wordpress - how to correct
We are using Yoast for a number of our sites. We use naked domain as the canonical. I have noticed in the header tags that all our sites show the canonical URLs as having a trailing slash: Example: http;//foxspizzajc.com, when I look at the source code, it shows the canonical as http;//foxspizzajc.com/ Of course, it is much more likely that all sites that link to us will not use the trailing slash - so preferably we do not want that to be the canonical - among other reasons. Does this need to be fixed so the trailing slash is removed? I cannot see how to do this in Yoast SEO or in Permalinks structure for Wordpress. Sorry for my ignorance. Thanks for any help.

Is there a way to get the domain authority of a subdomain?
For example, www.storage-mart.com and us.storage-mart.com both show the same DA in OSE. I believe it's the DA of the root domain. How can I compare the DA of the 'www' and 'us' subdomains?

Domain / Page Authority - logarithmic
SEOmoz says their Domain / Page Authority is logarithmic, meaning that lower rankings are easier to get, higher rankings harder to get. Makes sense. But does anyone know what logarithmic equation they use? I'm using the domain and page authority as one metric in amongst other metrics in my keyword analysis. I can't have some metrics linear, others exponential and the SEOmoz one logarithmic.

Page Authority is the same on every page of my site
I'm analyzing a site and the page authority is the exact same for every page in the site. How can this be since the page authority is supposed to be unique to each page?

What do you use for site audit
What tools do you use for conducting a site audit? I need to do an audit on a site and the seomoz web crawler and on page optimization will takes days if not a full week to return any results. In past Ive used other tools that I could run on the fly and they would return broken links, missing htags, keyword density, server information and more. Curious as to what you all use and what you may recommend to use in conjunction with the moz tools.
