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:

How can authority of the page be higher then authority of the domain?

In the opensite explorer most of the links that I see have a higher domain authority and lower page authority which makes sense to me because I thought that domain authority is an aggregate of its pages authority. But apperently I was wrong because sometimes I see that the page authority is greater then its domain? How could that be?

Keyword Difficulty Tool - How to use it the best way?

Hi, I am freshman, both, here on SEOmoz and in SEO generally and have a question concerning the assessment of KW difficulty. I did browse through the Q&A-Section (great content!!) but could not find a relevant answer to my problem. So I am currently building my initial keyword list, our website is only 2 months old, so we are still in the very early stage. Fashion is a very competitive area, so the KW Diff. Tool indicates high difficulty for a lot of words and phrases. however, I identified some with percentages <50 or even lower than that. Then I compared the results of the SEOmoz tool to Google Adwards and the Google results for competitiveness differed significantly. For example: for the KW Personal Shopping I got KWD from Seomoz 33% (in Germany) and from Google 0,5 for broad and 0,64 for exact search. I am quite confused how to make the right choices for my KWs now. Which metrics should I consider most? What else apart from the competition factor is behind the metric KW diff.? Does it matter in any way that I search from Germany for Germany in German? Do you have any further recommendations for the process of identifying the best Kws? Thanks a lot in advance, best from Berlin Tani

Why is Followed Linking Root Domains higher than External Followed Links?

Surely there must be at least one external link for each linking root domain? Some results for smaller sites give a higher number of domains linking in than incoming links - e.g. www.forbesandsawyer.co.uk Under Subdomain metrics: External Followed Links - 1 Followed Linking Root Domains - 2 Surely 2 root domains would mean AT LEAST 2 external followed links? Thanks, Andrew

Use of the tilde in URLs

I just signed up for SEOMoz and sent my site through the first crawl. I use the tilde in my rewritten URLs. This threw my entire site into the Notice section 301 (permanent redirect) since each page redirects to the exact URL with the ~, not the %7e. I find conflicting information on the web - you can use the tilde in more recent coding guidelines where you couldn't in the old. It would be a huge thing to change every page in my site to use an underscore instead of a tilde int he URL. If Google is like SEOMoz and is 301 redirecting every page on the site, then I'll do it, but is it just an SEOMoz thing? I ran my site through Firebug and and all my pages show the 200 response header, not the 301 redirect. Thanks for any help you can provide.

How to crawl the whole domain?

Hi, I have a website an e-commerce website with more than 4.600 products. I expect that Seomoz scan check all url's. I don't know why this doesn't happens. The Campaign name is Artigos para festa and should scan the whole domain festaexpress.com. But it crels only 100 pages I even tried to create a new campaign named Festa Express - Root Domain to check if it scans but had the same problem it crawled only 199 pages. Hope to have a solution. Thanks,
Eduardo
