      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.

            Add to cart redirect using 302

            I am getting a list of crawl errors in Moz because I am using a 302 redirect when people click on an item using the quickview add to cart eg:http://copyfaxes.com/cart/quickadd?partno=4061 will redirect them to the viewshoppingcart page. Is this wrong should this be a 301 redirect? There is no link juice to pass. Thanks

            How to increase page authority

            I wonder how to increase the page authority or the domain authority to begin with. It seems you are putting a lot of weight on this in your analysis.

            Is there a way to see what keywords users of my site are using to find it online?

            Since Google Analytics no longer shows the keywords used by people to find a site online, does the SEOMoz toolset provide somethng to show this data?

            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.

            How fast can page authority be grown

            I understand that it is easier to rank for a particular keyword given a higher DA score. How fast can  page authority be established and grown for a given keyword if DA is equal to 10/20/30/50? What are the relative measures that dictate the establishment and growth of this authority? Can it be enumerated to a percentage of domain links? or a percentage of domain links given an assumed C-Block ratio? For example you have a website with DA of 40, and you want to target a new keyword, the average PA of the top ranked pages is 30, the average domain links are 1,000, and the average number of linking domains is 250 - if you aim to build 1,000 links per month from 500 linking domains, how fast can you approximate the establishment of page authority for the keyword?
