      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:

            Domain still not being found in search

            Hi guys, I've been handed a client who needs some seo work. I've tweaked one of their pages to focus on a chosen keywords about 4 months back but still the site is not even visible using the new Domain Analysis tool from moz and it still won't rank at all for the keywords. Am I missing something here? Is there something blocking the SERP from listing the website? I've ran a site: search on Google and it returns 283 results on the website. It's puzzling me as there clearly is something stopping it from being ranked. The domain name in question is: https://cloud9inecommunications.co.uk Thanks in advance.

            Solved How to reduce the spam score for my domain?

            spam score

            My domain  longfeifei.com is for a regular company website and someone sent a lot of external links on different low-quality websites on the internet. Now the score is very high about 75%. If I disavow the unusual links from google search console. Is it possible to reduce the spam score? Is MOZ associated with GOOGLE Data? Thanks,

            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?

            Meta keywords no longer in use

            Can someone point me to the official article explaining why meta keywords are no longer taken into account by search engines please? I know Moz has indicated that search engines ignore them, but I would like to read a bit more about it - what was the reason behind it and since when.

            Why do some sites have a higher Page Authority than Domain Authority in OSE??

            Hi, I have noticed when using OSE and enter a domain you very often see a higher Page Authority than Domain Authority. If someone could explain why this would happen then I would be very grateful - its my current understanding that page authority would ALWAYS be LESS THAN Domain Authority but that is not always the case (I have seen cases where PA is more than 10 higher then DA) Here's an example where PA > DA http://www.opensiteexplorer.org/links.html?site=www.primelocation.com Thanks
