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 Audit
Hi What is the best tool out there to doing a full brand audit for company. They've created at least 15 websites and have possibly many domain names which have been ordered by different people over many years. I need to find the quickest and best tool to do this with. Any suggestions would be great.

Can increasing website pages decrease domain authority?
Hello Mozzers! Say there is a website with 100 pages and a domain authority of 25. If the number of pages on this website increases to 10,000 can that decrease its domain authority or affect it in any way?

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 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.

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?

Meta keywords no longer in use
Can someone point me to the official article explaining why meta keywords are no longer taken into account by search engines please? I know Moz has indicated that search engines ignore them, but I would like to read a bit more about it - what was the reason behind it and since when.

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?
