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:

Report is showing 2 different domains?

Hello SEOMOZ Fam, I am trying to get a understanding on what is the best method for me to do moving forward. I am just noticing that my reports are showing data for both http://domain & http://www.domain which is what has been confusing me for this whole past month. I have just went into my control panel and redirected domains to be just http://domain....will me doing this redirect clean up my next crawl report next week or are there other steps I need to do with my domain or even my campaign? I think I chose root level for my campaign setting. Thanks so much n advance

Does the page authority data also considers the on page factors like the presence of keyword in the title,meta text, and keyword frequency ??

The moz difficulty score considers four factors for the top websites. are the on page factors included in the page authority data ?

Can I get a list of all links on a given domain?

Sorry, this is actually kind of a tripartite question: I was looking at the Competitive Link Analysis on one my clients' campaigns. Sometime between June and September their total links went up by about 120,000. We have no idea where those links came from (although the numbers would indicate that they're mostly internal). Question 1: In none of the other tools can I figure out how to list these links on a domain level. Is there a way to get a list of all links for our given domain? I've been playing around with the page-by-page and even that doesn't show me everything. For example, I'm looking at OSE for their homepage and it lists 45 links for a page that it claims has 151 total. Question 2: How did it pick those 45 to display out of the 151 possible? If these are only external links, why do half of them come from one of our subdomains? Also... Question 3: If our client hasn't made any major changes recently, why has the number of internal links gone up so dramatically? Thanks.

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.

What SeoMoz tools should I use to track the sucess of my SEO efforts and find possible linking partners?

HI All, I am a new user to SEO moz pro and I have a few questions I hope you can help me with. We are adding a new product category to an existing site and I am wondering what tools to use to track our SEO efforts to build ranking for these new products. I have already started a campaign that tracks the ranking of our primary keywords but I am wondering if there are other tools I should be using as well. Currently our SEO strategy is centered around link building. I have been approaching sites that have content related to our products and offering to write articles, guest blogs, and create educational resources that benefit the sites users and have specific anchor text linking back to our site. Since we are trying to build rank for a new category of products should I be linking to the general product category page or should I try to link to sub categories or individual products? Also I have used the juicy link finder to help me identify related sites that I can approach but I haven't received very many good leads. Is there a more specific way to use the tool or another tool that I should try? If you have any suggestions about other SEO strategies/activities that we should be pursuing please share your ideas! Thanks!
