Why does SEOmoz assign such a high Domain Authority to subdomains on blogspot, typepad, wordpress.com, etc.?
-
I thought it was generally accepted that the search engines treat joesmith.wordpress.com and www.wordpress.com as completely different domains. In which case, a cute but obscure blog like http://monkeysalwayslook.typepad.com/ has no business having a DA of 95.
-
Did you know we have a feature request forum at https://seomoz.zendesk.com/forums/293194-seomoz-pro-feature-requests where you could submit that idea?
Do keep in mind that we don't have access to Google's algorithm either, so it would be our idea of how it is influenced, not what Google thinks about it.
-
Getting a quick look at my competitors' high-DA inbound links is helpful to me as I assess the strengths and weaknesses of their link profile. Right now, I have to filter out a bunch of fake-high-DA wordpress, typepad, and blogspot blogs -- and meanwhile, I don't have a clue how Google actually feels about those subdomains. This annoys me. So a change like the one I am proposing would make me less annoyed.
Obviously I understand that finite resources go into developing these tools, which is why I'm not demanding that this be changed!11!1eleventy

That may be true, but my question was...how EXACTLY would you use that data to make a business decision?
The point I was trying to make is....
Google devalues a tremendous amount of links based on spaminess and other factors. PA and DA were not fully aligned with PR previously. They did offer insight into a site's backlinks but we accepted it could differ from Google based on various factors such as:
-
Linkscape does not crawl as deeply or as fast as Google
-
OSE also cannot differentiate between a "good" link and a bad one.
-
OSE also cannot differentiate between a sidebar link, a footer link and an in-content link
Please don't get me wrong. I like OSE and use it daily. I often see SEOs and site owners trying to use PA or DA in a manner that, in my opinion, it is not effective. I use PA and DA as an indicator, not the determining factor.
For example, I may see a new site which is well designed, has fantastic content and a passionate owner. I know this site will grow over time and would gladly pursue a link from it. On the other hand, I may see a site with great PA and DA, but it is not ranking well due to Panda issues. Clearly these issues affect the value of any links received.
There are many other examples I can share but the point is, you can use the PA and DA as-is and gain value from them. Penguin is undergoing a major update which will likely further change the link landscape. There is so much volatility related to links right now it is hard for a software company to invest money devising a link measurement system which will likely need to undergo a major change before it is published. My two cents.

It would make the SEOmoz data more in line with actual rankings. I would guess that treating these UGC subdomains as their own domains with their own DA would make DA correlate a bit better with rankings.
-
The couple of times I've found my content duplicated on a Wordpress.com domain, they've removed the content or banned the blog (which was entirely copies of other peoples' content) right away.
-
One example that may be relevant is the franchise owners who asked a question last week.
What if you are in London competing with:
We know (strongly believe) that Google treats subdomains as a separate site and subfolders as the same domain. London.somefranchise.com may have a "real" DA of 14 and you use that info the way you use any DA info. That's not the site you want to partner with if someotherlondonfranchise.com has a DA 40.
Meanwhile, the main somefranchise.com may have a DA 89 so you pursue a relationship with London.somefranchise.com because their DA is 89...but it's not. Having the subdomain's actual DA would help.
-
You can offer that suggestion to SEOmoz here: https://seomoz.zendesk.com/forums/293194-seomoz-PRO-feature-requests
Can you help me understand how this information would be helpful? What if SEOmoz made the exact change you were requesting. How can you use that data to make a difference for your site or the sites of your clients?
-
While that all may be true, they do have the ability to enforce their terms as they see fit, and do so at times.
-
I guess my question should actually be "Why doesn't SEOmoz treat this kind of subdomain differently from other subdomains, since we're pretty sure Google does treat it differently?"
-
"There are specific standards which must be maintained."
I don't believe that's true. UGC companies always mention lots of things you're not supposed to do in their TOU, but that (to use another acronym) is pure CYA. They do not proactively patrol the UGC they host. They have extremely limited legal liability for that content (in the U.S., at least). Content on a wordpress.com subdomain is not particularly likely to be good or trustworthy.
-
Domain Authority, as assigned by SEOmoz, applies to the root domain. It is part of the fundamental definition of the term. All the details can be found here: http://www.seomoz.org/learn-seo/domain-authority
An important factor to consider is any subdomain on wordpress.com is owned by WordPress. There are specific standards which must be maintained. WordPress has the right to recall any subdomain for a variety of reasons, or perhaps no reason at all depending on their contract.

Why is my domain not being crawled anymore?
I just noticed that right around 12/1/2012, SEOMoz stopped crawling all but two pages out of the 400 or so on my website at www.TrustworthyCare.com . I speculate that this is probably due to some dumb mistake I made at that time, but I can't for the life of me figure out what that mistake was. Before that, the weekly crawls included all 400 or so pages. I wonder whether it's something that changed in our .htaccess file. Here's how that file looks now; can anyone see what is wrong there, or perhaps offer other suggestions if it doesn't look like anything is wrong in it? Thanks!

PPS - I found and read this page, but I've pretty much tried the things described there (I think):

Page Authority Bulk Check?

SEOmoz bot and "noindex"
As a recent newbie to SEOmoz, I've been implementing some suggestions and doing a general tidy up. I removed URL's from our robots txt, and rolled out instead the noindex meta tag to pages we don't want indexed. But surprised to see issues that are now flagged from the last crawl by the moz bot from pages that have this meta tag? Does the SEOmoz bot not ignore this tag? Just want to make sure I've implemented it correctly, so the google bot does ignore it. Meta tag syntax is and is placed below the title tag. cheers Steve
