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:

Items listed based on size - Use "inches" or " " "
I sell Decorative nutcrackers of various sizes. At this time, I use the term "inches". I was looking at my competitor the other day, and when I did a search on his site, using the term inches did not provide me with a result. I was forced to use ex. "10" nutcracker" instead of "10 inch nutcracker". Is there a preferable usage for seo purposes. Thanks! my site: http://www.nutcrackerballetgifts.com/category/5/10-Inch-Nutcrackers.html his ite: http://www.kurtadler.com/Search?search=10"+nutcracker

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.

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

Comparing Domain Authority Scores
Since your scale (like PageRank) is a logarithmic scale, it makes it hard to judge the distance between 2 scores. Can you give me a rule of thumb. For PageRank, each jump is an exponential jump - so that a PR6 is perhaps 10 times stronger than a PR5. What is the log base that SEOMoz uses. Should I assume that a 60 is 10 times stronger than a 50? This is important when it comes to measuring progress because growth is going to get more difficult as you move up the scale and I need to communicate the distance between our current Authority score and our goal. Thank You!

How is domain authority related to country top level domains?
I've noticed that for some country top level domains (tld) the domain authority returned by open site explorer is based on the domain that has been registered within the tld. For example, domainname.co.uk provides a domain authority specific to the domain. However, for some other country top level domains, this does not appear to be the case. Examples I have found include: domainname.co.nr domainname.co.pt domainname.co.ee For these top level domains the domain authority seems to be the same for every domainname, seemingly implying the domain authority is for the top level domain itself rather than for the domain. Is this a common situation for many country top level domains, so that what I see going in here is the tip of a large iceberg, or does this situation just apply to a very isolated set of country top level domains?

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
