Does MozAuthority calculates the MozAuthority of each incoming link?
-
Hey Mozzers!
So as I'm checking MozAuthority as a primary parameter to determine if a co-operation with a website is worthwhile, I did notice that it's mainly based on QUANTITY of inbound links.
My question is this: Does my site's MozAuthority calculates The same parameter from each incoming link?
Example:
My site, www.google.com, has 5 incoming links from low MozAuthority domains.
Your site, www.facebook.com, has 5 incoming links from medium MozAuthority domains.
His site, www.yahoo.com has 5 incoming links from high MozAuthority domains.
Will the 3rd case necessarily have a higher MozAuthority than #1 and #2?
-
Joram and Adam are essentially correct. MozRank is built to emulate PageRank, and so it does take into account the MR of the incoming links, not just the total count. It is in essence, though, a measure of quantity - just a complex one. Links from sites with more links count more, so that's a quality signal, in an abstract way, but we don't take into account the relevance of the links or spam factors.
Domain Authority is much more complex and is a machine-learning model based on observed Google rankings. Essentially, it's an attempt to predict the ranking power of a site.
-
Yes it does in the end.

Thanks, Adam.
I was looking for a quote at the "Learn SEO" section that you linked to, and there isn't any ;\
-
Thanks, Joram.
So in the bottom line - does Domain Authority also calculates the DA of each inbound link?
-
I think you mean either DomainAuthority or mozRank when you mention MozAuthority. mozRank is similar to Google's PageRank and Domain Authortiy is a metric based on a combination of all domain ranking factors.
As far as I know mozRank is mainly based on the number of inbound links and the populairity of the websites that link to you. So here your assumption will be true.
With Domain Authority a lot of other metric are taken into consideration as well to calculate the final score, such as domain trust metrics, social signals, etc.

Moz Authority metrics are based not on the total number of links, but the authority each link passes. A page with links from 5 high authority pages will generally have much higher authority metrics than a page with links from 5 low authority pages.
Will the 3rd case necessarily have a higher MozAuthority than #1 and #2?
Probably, but not necessarily:
- It's possible to get links from low authority pages on high authority domains, which would only pass a small amount of authority.
- A page with a lot of links will pass less authority to each link.
My answer uses some generalizations, here are more details on the specific metrics:

Plan for Analyzing and Optimizing Internal Link Structure
I've noticed that our site has what appears to be a poor ratio of external-to-internal links. I know there are no hard and fast rules in SEO but generally I've come to understand that this ratio should be relatively balanced, and in some cases I've seen some correlation of high-performing/ranking sites closer to 70-30 (external-internal). I'm not going to get into specifics, but our ratio is well-below 50-50 (heavy on internal links compared to the volume of inbound external links). My hypothesis is that this is diluting the link equity/authority for the domain. Moz's tools don't really provide any data beyond the initial data point of the volume of internal links compared to external. Being that I've never really gone down this rabbit hole before, I'm wondering if anyone else has ever experienced anything similar and could point me in the right direction. Thanks in advance for any assistance or guidance!

Link from Gizmodo disappeared from Open Site Explorer
Hi, I have been using OSE to check competitor links, DA, PA etc. And recently noticed that an author at Gizmodo was kind enough to link us to a blog post of his. This is great news as Gizmodo has a DA of 94 and a PA of 50 (Which is pretty big compared to our DA of 30 and PA of 42). The link to the post is here: http://gizmodo.com/5956401/everything-you-need-for-the-best-trick+or+treating-house-in-the-neighborhood And the link to our website is: http://www.electromarket.co.uk/lighting-effects/lighting-effects/strobe/ffa0144 It was showing on OSE for the past few days but now it has vanished and it is showing channel5 (TV Channel in the UK) as the highest DA linking to us, which is still pretty good. But I just want to know why the link has stopped displaying on OSE 😞 Any help or insight is appreciated! Tom

SEOMoz Link Analysis Not Updating?
Hi there, I am wondering why the Link Analysis in SEOMoz takes so long to recognise new back-links. I have had the same figures showing for months when I know that I have added a lot more backlinks that are showing in my Google WebMaster account and I have also proven exist by searching directly in Google's search engine. How often does the Link Analysis section update itself? Are these figures worth following at all or are they useless? Thanks!

Links not appearing on Open Site Explorer
My site gained several new inbound links during December and only two of them are not all showing up on the latest Linkscape update. It seems to be the links that were created at the end of the month which are showing up, whereas a handful at the beginning of the month are nowhere to be seen. All the linking pages have been indexed by Google the links are do-follow, and one of the sites in particular is not obsure and has a DA in the 90's. I appreciate the Linkscape doesn't index everything, but I would have thought that more tof the results of my efforts would have shown up in OSE. I'd be really grateful if anyone could explain this to me please. Thanks Ben

Why doesn't the BBB / Trustlink.org links show up in the Link Analysis?
I am curious why one of my client's main competitors (www.allbayhardwood.com) shows links from the Better Business Bureau and Trustlink.org (associated with BBB) but links from those sources do not show up for his domain (www.sanjosehardwoodfloors.com). He has been a BBB Acredited Business since 12/2010 and on file with them for probably as long as they have had the online version, which seems like plenty of time for the link to have been picked up. BBB has a very nice domain authority and it would be great to see these links show up. (they don't show up in webmaster tools either) Is there something I am missing? Thanks in advance guys and gals! (I know the site has other SEO issues - just getting started on pounding everything out.)
