Page authority questions?
-
I've been analyzing some IT communities ...in order to check how relevant is the page authority vs PageRank. I found one main site which is organized by "communities'..and every community is a sub-domain. The root domain has an authority of 90/100 which it should be great......so the sub-domains "inherit" part of this authority.... Until here everything seems to be perfect. However, I went deeper and I picked one of these communities. Analyzing the "Linking Root Domain" I discovered it only has only 5 root domains pointing to its home page. Those 5 Root Domains have generated more than 134k links. That doesn't seem to be "natural".
Checking those 5 Root Domains I discovered that they have been registered by the same Root Domain site.
Ex:
Main domain: Domain.com
Linking Root Domains: DomainXY.com
It seems to me that it is easy to cheat the authority domain score. Just creating others sites developing the same topic and generating back links to your main domain

So, keep in mind that "cheating" Page Authority isn't really very useful - we're just creating a predictive metric. We have no control over whether you actually rank. PA is a machine-learning model designed to predict the ranking ability of a page, but it's far from complete or perfect (no one number can be, although we're trying to improve it all the time).
Sub-domains are tricky animals. Sometimes, they inherit a lot of power from the root domain. Sometimes, they get fragmented and essentially act like entirely separate domains. Our PA model doesn't really account for all of that complexity. It's a best guess, ultimately. There are certainly cases, though, where a sub-domain ranks well without many unique links, solely based on the power of the root domain. That's far from guaranteed, though.

What is the site that you analyzed? Comparing PA versus PR isn't going to help you btw. Page rank can be manipulated as well very easily. For example I seen a pr4 for sale on godaddy auctions today for $5.00. The site had 0 backlinks. The site has been down for 1 year. So how does it still have a pr4? Pr4 to me isn't a good indication to link to anymore at all. People buy high pr sites daily and can make them look like they are 10 years old fast. I count on PA and DA to give me a good indication, because most people aren't cheating DA and PA if there is truly a way to do it. Also, to cheat it, you would just be cheating for your own confidence and it wouldn't do anything to help you rank better if you cheated yourself to a high one.
So to sum it up, I feel that PA or DA is much more accurate and up to date than PR. Sure PR still has some weight if your going to buy a site, i think it's burnt into our brains that we need a good one, but it's not everything.
Have a great night.

Domain Authority Dropped from 13 to 1
Hi there, I know Domain Authority is not a KPI, it's a relative metric but we saw a huge dropped down in our domain authority this week and I got worried. I am trying to understand why this happened? Any idea? Our website link is here https://www.wealthmanagementcanada.com Is it something related to Moz update or with our website? Regards,

Seomoz legacy pages?
Hello, I am finding that I miss several of the old seomoz sections. The legacy tools in particular like the visual website comparison. Where is that now? Also, where is the ongoing list of the top 100 sites? So much was lost in the shift to MOZ, I hope some of the good old stuff is still available. Thank you, Nolan

Benefits of reducing on page links
This is more of a discussion point. What would be the measurable results of reducing the number of on page links, specifically on a home page, but let's assume by way of a large navigation menu most of the pages have a lot of links" For instance, would any of the stats on the MozBar be affected (let's start with the home page). Would the Page Authority or MozRank change at all, perhaps because there is less "juice" flowing out of the home page? Thanks! 🙂

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?

Multiple Page Title Elements?
Greetings, I am baffled by the recommendation I repeatedly receive from seomoz's on-page optimization tool. The web page I am working on only shows one title between <title>and</title> in it's head. However, seomoz is also reading "Pass to multiple" from somewhere. It recommends that I "Avoid Multiple Page Title Elements" and I would like to but cannot find them. Any suggestions? By the way, I inherited this site and am just trying to deconstruct someone else's work. As a novice, I realize there might be some obvious explanation that I am just missing. Thanks!
