    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:

          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,

          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.

          How long for authority to transfer form an old page to a new page via a 301 redirect? (& Moz PA score update?)

          Hi How long aproximately does G take to pass authority via a 301 from an old page to its new replacement page ? Does Moz Page Authority reflect this in its score once G has passed it ? All Best

          What user agent is used by SEOMOZ crawler?

          We have a pretty tight robots.txt file in place to only allow the major search engines.  I do not want to block SEOMOZ.ORG from being able to crawl the site so I want to make sure the user agent is open.

          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

          TLD vs Sub Domain in Regards to Domain Authority

          I have always been under the impression that top level (or root) domains can hold different domain authority than that of a sub domain. Meaning that sub domain's and TLD can hold different ranks and strength in search engine result pages. Is this a correct or just an assumption? If so when i add a root domain and subdomain into the campaign manager i get back the same link information and domain authority? www.datalogic.com
          www.automation.datalogic.com Have I made an incorrect assumption or is this an issue with the SEOMoz campaign manager?
