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!

I bought a 5 year old domain and has a spam score of 23%.....
A few months ago i bought a 5 year old domain and when i went to check in Moz pro the spam score, it shows its at 23%. DA is 1 everything else is 0. The spam score shows 23% but there are no links at all for this website (see image) https://imgur.com/a/3lHjLEh I don't understand, there are no links at all going to this website. I checked google search console, analytics and tried looking for any links linking to this domain and there is none. Even Moz isn't showing any links in the picture i provided above. Is this a glitch? Can i reset my spam score on this domain? Does that mean i wasted my money on this domain and now i can't rank with it? Is there something im missing here. I also checked is there are any warnings or manual actions and it clearly says "No issues detected". A few months earlier i bought a brand new domain very close to the 5 year old domain (new domain has a z instead of an s) and the spam score on that is 0 and DA is 1. Given that the 5 year old domain has a 23% spam score, does that mean i should use the other new domain instead and redirect the 5 year old domain to the new website?

Items listed based on size - Use "inches" or " " "
I sell Decorative nutcrackers of various sizes. At this time, I use the term "inches". I was looking at my competitor the other day, and when I did a search on his site, using the term inches did not provide me with a result. I was forced to use ex. "10" nutcracker" instead of "10 inch nutcracker". Is there a preferable usage for seo purposes. Thanks! my site: http://www.nutcrackerballetgifts.com/category/5/10-Inch-Nutcrackers.html his ite: http://www.kurtadler.com/Search?search=10"+nutcracker

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?

Comparing Domain Authority Scores
Since your scale (like PageRank) is a logarithmic scale, it makes it hard to judge the distance between 2 scores. Can you give me a rule of thumb. For PageRank, each jump is an exponential jump - so that a PR6 is perhaps 10 times stronger than a PR5. What is the log base that SEOMoz uses. Should I assume that a 60 is 10 times stronger than a 50? This is important when it comes to measuring progress because growth is going to get more difficult as you move up the scale and I need to communicate the distance between our current Authority score and our goal. Thank You!

How is domain authority related to country top level domains?
I've noticed that for some country top level domains (tld) the domain authority returned by open site explorer is based on the domain that has been registered within the tld. For example, domainname.co.uk provides a domain authority specific to the domain. However, for some other country top level domains, this does not appear to be the case. Examples I have found include: domainname.co.nr domainname.co.pt domainname.co.ee For these top level domains the domain authority seems to be the same for every domainname, seemingly implying the domain authority is for the top level domain itself rather than for the domain. Is this a common situation for many country top level domains, so that what I see going in here is the tip of a large iceberg, or does this situation just apply to a very isolated set of country top level domains?

Spam Directories creating misleading Authority ratings
How does the website www.starsdirectory.com.ar get a Domain Authority of 54 and a Page Authority of 61 when Google quite correctly gives it a PR 0? It is clearly a spam directory, which Google has recognised. It is very misleading using OSE or Campaign Management when sites such as these (and there are hundreds more we have found) are skewing the results of competitiors through the use of spam links. Is there no way that SEOMoz tools can identify such spam sites when they create their ratings?
