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.

Changing domain from .net to .se
Hi Guys, We have someone in the process of changing our domain from an 11 year old domain to a newer country domain of .se, He is not a web expert although he knows a lot of things. I am just wondering is there a checklist anywhere of things that are very important here that we should be aware of or he should be implementing so we can just double check that he is/ we are moving in the correct direction. Thank you for your Help. Rootin and Tootin xx

Campaign Domain "change" (www. vs no www.)
Hello, I'm tracking a domain (with www.thespin.be) since months. Last week we changed things related to domain & server and now SEOmoz has 0 pages crawled. I think that's because now my main domain is without www. (thespin.be). How can I modify my campaign to reflect this "change" (that's not really a new domain..) to avoid losing all my campaign history ? Also, on Google Webmaster Tools it's like I have 2 different sites (one with www. and another without), although I've defined my favorite domain (without www.) months ago.. Google won't update its index. And I have this problem on several other sites.. Thank you very much for giving me a feedback. Regards Jean-Louis

Why is the linking root domains count not increasing
For the last month I have been tracking my backlinks thru open site explorer. Over the same period I have gone on a minor link building exercise via social media, some directories as well as writing fresh new content for the site. However, my backlink count has increased in the Rank Tracker tool but my root linking domains have remain at the same level. Is there a lag or is this because some of these site are not in the open site index? To be specific - I have personally setup follow links from sites like tumblr, posterous, stumbleUpon, delicious and other like these. Would really like to understand the limitations so I can take the appropriate action. Thanks

In competitive domain analysis my website shows pages that I no longer have.
When I go to my campaign, link analysis, under competitive comparison/followed backlinks, the 5 pages under Anchor Text/Target URL, supposedly on my website, are not on my website anymore. I recently moved my domain name to another server (before signing up for seomoz) and deleted the forum associated with my website. Those 5 pages are all from that now extinct forum. What's going on?

Domain authority decrease after open site explorer update. Reasons?
Hi! I just noticed a decrease on our domain authority and also the page authority of several of our pages on the SeoMoz toolbar. For instance, DA went from 34 to 29. I was scared and confused, so I went to check it on the opensite explorer and saw that it had been updated. I want to ask you guys if the same happened with your metrics or is it just us. Because the strange thing about it is that we have been doing some good optimization work lately and also some linkbuilding, and actually our SERP’s have been improving in general, and some specific ones have been performing great. Our website is http://www.inmonova.com as a reference. Can anyone cast some light into this?

Why does new Keywrod tool show incorrect domain linking to root domain count?
Why does new Keywrod tool show incorrect domain linking to root domain count? Why does the "Root Domain Linking Root Domains" column show "4,764" for Homefinder.com/IL/Chicago yet when I run OpenSiteExplorer for homefinder.com it shows "2,963" Linking root domains. Why are these two numbers different?
