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:

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!

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?

TLD vs Sub Domain in Regards to Domain Authority
I have always been under the impression that top level (or root) domains can hold different domain authority than that of a sub domain. Meaning that sub domain's and TLD can hold different ranks and strength in search engine result pages. Is this a correct or just an assumption? If so when i add a root domain and subdomain into the campaign manager i get back the same link information and domain authority? www.datalogic.com

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

Spam Directories creating misleading Authority ratings
How does the website www.starsdirectory.com.ar get a Domain Authority of 54 and a Page Authority of 61 when Google quite correctly gives it a PR 0? It is clearly a spam directory, which Google has recognised. It is very misleading using OSE or Campaign Management when sites such as these (and there are hundreds more we have found) are skewing the results of competitiors through the use of spam links. Is there no way that SEOMoz tools can identify such spam sites when they create their ratings?
