How to Calculate % improvement in Mozrank and Domain Authority
-
I understand the concept that mozrank and Domain Authority are measured on a logarithmic scale . http://www.seomoz.org/learn-seo/mozrank
I'm trying to determine the percentage improvement in the Logrithmic value. For example
Original Domain Authority 60
Original Mozrank 5
End Domain Authority 63
End Mozrank 6.
So 5% change in DA and 20% change in MozRank. How do we convert these numbers to the real logrithmic change?

He's giving you a nonsense number, because SEOMoz won't reveal the true scale, so use whatever logarithmic scale you want.
ie. an indeterminate amount

Super interesting question!
First, let me put out a disclaimer that metrics like Domain Authority are comparative metrics that change from index to index. This means that it's best to use these numbers to compare yourself to the competition, but not to your own previous metrics as the base calculations can change. DA measures relative strength - so it's completely possible to improve 10% by raw numbers, but if your competition improved 10% as well, your relative DA really didn't change. For this reason we caution against folks measuring DA over time, and instead using it as indicator of ranking potential in real time against other competitors.
With that out of the way, last time I checked, MozRank was calculated on an algorithmic base scale of around 8.5. (Sorry, I can't be more specific - but that's part of the secret sauce. Heck, I don't even know the exact numbers.
With this knowledge, you can use a typical base calculator to figure relative strength. For example, a Mozrank of 5 on an 8.5 log scale calculates to 44370.531 um... raw MozRank points. Using the same calculations we find a MozRank 6 equals 377149.516 raw points, or 8.5x the original.
You can do similar calculations to determine the logarithmic change of DA, but keep in mind the disclaimer above and remember that since we can't reveal the exact scale, your calculations will be estimations, at best.
Hope this helps!

Sorry can you elaborate?

Multiply the original MozRank by a buck two eighty.

Best SEO for New Lead Gen Site: Use Corporate Domain or Product Name?
Hello, wanted to poll the Moz community about a URL discussion my company is having. We plan to launch a new publicly-facing resource and want to leverage organic search as much as possible. For the domain, we’re considering these options: the corporate domain since it’s well established or the URL for the product, which is more descriptive of the content that will reside on the page, but doesn’t have much authority because almost all of the relevant content is behind a paywall. The product domain is appealing because we want to build brand recognition. Should we also look at a more specific domain for the topic that doesn’t leverage either branded domain? Any Moz tools you’d recommend to help research this decision? Thank you in advance for your thoughts!

SEOmoz PRO: How to manage a Site with 2 languages on the same domain - without mixing up data?
I want to track a "rootdomain" that has two languages on it, the english version is in a subfolder /en/ 1. http://website.de
Moz Pro | | inlinear
2. http://website.de/en/ I want to manage and track each language-version isolated. So I will setup:
1. http://website.de as campaign DE - german
= as Root Domain
But as there are links to the /en/ Subfolder these data will also be included in all reports. And there is still no option in SEOmoz PRO to exclude folders or even urls.?! This will be bad when wanting a clear report of just one Language Version. 2. http://website.de/en as campaing EN - english
To track as "Subfolder" will not work beacause this option will only consider exactly this subfolder... So is there a way to see data just only for one language Version?0 -
Why did Domain Authority go up so much? Did you change your measurement?
Our Domain Authority has been at 42 or 43 for a couple months and it just increased to 54. Why did this happen? I would like to think that it is because of out SEO and linkbuilding work. However, I suspect something else may be involved because the 3 competitors we track also all increased between 10 to 25 points at the same time. What happened? Did you make changes in the way you score DA or is this the result of changes in what pages you crawl? Or what?

Why would PA be 1 (0 links from 0 root domains) if it's linked to internally?
Question just about said it all: I've seen a number of pages on sites that have a PA of 1 (with the metrics being 0 links from 0 root domains) when I can see on the site that it is linked to internally - from the main nav (which is CSS, not Javascript) and also from the footer, if not other places. Why would this be? Update: upon looking further at the site, it appears that there's some kind of redirect going on, where the page linked to from the nav actually redirects to the real page. Would that eliminate PA, even if it's a 301? And additionally, is whatever is causing this lack of PA a reflection of how Google would relate to the page? Thanks, Aviva
