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:

Domain Authority Goes Down After Https change
We just moved our domain from http to https. We have been at a solid 89 for domain authority for the past year, but this month we are now at 88. Does changing to https cause the domain authority to go down and is this just a temporary fluctuation?

Used a free WP theme and now Webmaster Tools has shown hundreds of broken links
Hello everyone, We've recently launched two new music instrument listing websites. One in the US http://www.yourinstrument.com One in AU http://www.yourinstrument.com.au While we're waiting for our custom, branded WP to be built, I went and put up one of the free themes with closely matching colors. Clearly, this was a mistake because now my WMT account has spit out around 200 'not found' errors and my Moz account is calling them around 282 'dupe page titles' and 'content'??? 1. Aren't WP outbound links supposed to be 'nofollow' ? / Why is my theme creating strange links? 2. Can I clean all these up with assigning rel=canonical to the original blog post? Do I need to wait for the new theme to be installed and then 301 the random URLs found by Moz and WMT ? weird link examples: http://imgur.com/Cm6pO5H Please help 😕

Using Your 50 Monthly SERP Analysis Reports
Hi. I've been running analysis on a variety of keywords for a few of our clients and am noticing I'm going through our 50 monthly full SERP Analysis Reports pretty quickly. While SEO is only a fraction of what we do, I know there are large SEO shops out there that must run a tremendous amount of analysis each month. If you're running such analysis routinely, how do you manage with only 50 full SERP Analysis Reports each month? How do these reports fit into your workflow? Thanks a lot. David

NoFollow Links from Subdomain to root domain better than DoFollow Links?
Our service at fotograf.de is a shopsystem for professional photographers. The customers can build their own website with our tool including an onlineshop to sell their pictures. Here is my question: One part of the customers use subdomains of our site like photographers.fotograf.de. On each customer website we include a backlink to our homepage www.fotograf.de. From SEO view is it better to set these links as NoFollow Links? Or should we put one Follow Link on the starting page on each site and on the other pages only NoFollow Link? Are these links bad for our SEO regarding link diversity because they all come from one root domain? Thanks for the answers! Sebastian

What is more important, page authority or linking root domains?
I have 2 pages in my report that are identical: www.ferringway.com (more page authority......21 vs. 1) www.ferringway.com/index.php (more linking root domains...... 40 vs. 21) Which one should I delete or should I do something like a 301 redirect? Your help is greatly appreciated! Sheryl

I want to hire someone to write some PHP code using the SEOmoz API.
...but I'm not sure how to go about it. What I need is simple: all I want is to be able to paste a list of URLs (different domains), and have the program return the Page Authority for all those URLs. I understand I can use the free SEOmoz API, particularly the URL Metrics API. Then I want to export the data to an Excel file. That's it. Problem is, I have absolutely no clue how to do it. Obviously I'd pay someone to do it. Pay very well if you can do it professionally and quickly. How can I go about finding the right person for the job? Apologies if this is not the right place to ask this, but I don't know where else to go. Thanks.
