      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:

            Unsolved Using Weglot on wordpress (errors)

            wordpress weglot

            Good day to you all, Does anyone have experience of the errors being pulled up by Moz about the utility of the weglot plugin on Wordpress? Moz is pulling up URLs such as: https://www.ibizacc.com/es/chapparal-2/?wg-choose-original=false These are classified under "redirect issues" and 99% of the pages are with the ?wg-choose parameter in the URL. Is this having an actual negative impact on my search or is it something more Moz related being highlighted. Any advice be appreciated and a resolution .. Im thinking I could exclude this parameter.

            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.

            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 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.

            Page Authority is the same on every page of my site

            I'm analyzing a site and the page authority is the exact same for every page in the site. How can this be since the page authority is supposed to be unique to each page?

            Batch lookup domain authority on list of URL's?

            I found this site the describes how to use excel to batch lookup url's using seomoz api. The only problem is the seomoz api times out and returns 1 if I try dragging the formula down the cells which leaves me copying, waiting 5 seconds and copying again. This is basically as slow as manually looking up each url. Does anyone know a workaround?

            How to check Page Authority in bulk?

            Hey guys, I'm on the free trial for SEOmoz PRO and I'm in love. One question, though. I've been looking all over the internet for a way to check Page Authority in bulk. Is there a way to do this? Would I need the SEOmoz API? And what is the charge? All I really need is a way to check Page Authority in bulk--no extra bells and whistles. Thanks, Brandon
