How is DA and PA calculated?
-
I'm interested to know how DA and PA is calculated.
Is it calculated exponentially? i.e. increases out of proportion compare to the power and quantity.
So assuming all things are equal... One link of DA40 would be much more powerful than two DA20's?
-
I am also curious about DA and PA. My website Carpet Cleaner Picks DA is 2 while PA has reached upto 25. PA is increasing constantly since the launching of the website while DA stands still. Why is that?
Secondly, I am also curious if DA or PA has any effect on the rankings.

Hi there!
Thanks so much for the question!
Roman is correct that we use a variety of different Moz metrics and data to calculate Domain Authority and Page Authority including overall link profile (based on the Mozscape Index), MozRank, MozTrust, and more. Both these scores are on 100-point, logarithmic scales so it's important to note that it can harder to grow your from 60 to 70 than from 10 to 20. I also want to make sure to mention that if sites with higher Authority are linking to your site, that Authority will ripple down to all the other links that are connected to it. Basically, DA is our best prediction of how content from your site will rank in SERPs (PA is a similar metric but is page specific) so the higher the score, the better!
I hope this helps!

Domain Authority is calculated by evaluating linking root domains, number of total links, MozRank, MozTrust, etc. — into a single DA score. This score can then be used when comparing websites or tracking the "ranking strength" of a website over time.
Page Authority is based on data from the Mozscape web index and includes link counts, MozRank, MozTrust, and dozens of other factors. Like Domain Authority, it uses a machine learning model to identify the algorithm that best correlates with rankings across the thousands of SERPs that we predict against, then produces Page Authority scores using that specific calculation.
Is it calculated exponentially? Just the developers of the algorithm can answer that question. But I'm pretty sure the algorithm is based on a Statistic Framework and Not on Arithmetic, Exponential Framework
Depends let's take an example
website.com/cartegory-1/ with a DA=40 is better than 2
website.com/cartegory-1/sub-category-2/sub-category-3/sub-category-4
website.com/cartegory-1/sub-category-2/sub-category-3/sub-category-4IF THIS ANSWER WERE USEFUL MARK IT AS A GOOD ANSWER

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.

Flauctuating number of Internal Equity-Passing Links affecting DA
My site has a high number of fluctuating internal equity passing links in open site explorer from month to month, theses range from 30 000 and sometimes as high as 1,million. The fluctuations occur even when I have made no changes onsite. I have noticed that when the internal equity passing links are very high the DA drops and when they are low the DA is high, has anyone ever experienced this with open site explorer ?

Site moved to https and not showing any Moz DA or PA
Hello Fellow Mozzers, So, I have a client site that we moved from non https to https at the end of 2015. We had decent moz numbers (Da/Pa etc) but now we are only showing a 1 for both of them. Does it usually take time for Moz to carry over the info to the https version or does that process entirely start over? Not sure where to start looking. Cheers D
