Why some domains and sub-domains have same DA, but some others don't?
-
Hi
I noticed for some blog providers in my country, which provide a sub-domian address for their blogs. the sub-domain authority is exactly as the main domain. Whereas, for some other blog providers every subdomain has its different and lower authority.
for example "ffff.blog.ir" and "blog.ir" both have domain authority of 60. It noteworthy to mention that the "ffff.blog.ir" does not even exist!
This is while mihanblog.com and hfilm.mihanblog.com has diffrent page authority.

Hey!
DA scores are specific to the root domain, we are not taking into account a subdomain. So even if you search a subdomain that doesn't exist (ffff.blog.ir), DA score is still only relevant to the root domain (blog.ir) which does exist.
Page Authority on the other hand is specific to the exact page you are searching, so it makes sense that mihanblog.com and hfilm.mihanblog.com would have different page authority scores are they are separate pages.
Hope that helps, let me know if you have further questions.

Am pretty sure that Moz just unifies DA stats in some circumstances when they have no 'actual' data for the subdomain in question. Sites which are very important, which have a number of sub-domains (but not hundreds or thousands) often render different results for DA metrics. For some blog platforms (blogger is a good example, also "blogname.wordpress.com" WordPress hosted blogs) - they have thousands or hundreds of thousands of sub-domains and Moz can't index all of them
In these situations, if Moz comes across a subdomain which is well-linked across the web it will separate it out and ascribe unique values. For the rest (of which Moz holds no data), it probably just unifies the DA metric with the root domain
It's a symptom of an incomplete index of the web. That being said, no one has a complete index of the web - you have to work with what you got

Crawler doesn't discover the links in the main nav
Hi Moz Community, We have a headless ecom (Magento) client that I'm trying to crawl the site. During the crawl, the tool (Screaming Frog) cannot discover the sub-category URLs in the main navigation when I start crawling via homepage. Similarly, when I start crawling with one of the sub-category page, it doesn't crawl any of the product URLs on the sub-category page itself. When I inspect product and sub-cat URLs through Search Console, they seem as indexed and if I view how Googlebot rendered the sub-category page, I can see the product URLs on the sub-cat page too. If you have any idea what's the issue with Screaming Frog and would like to help me out, I'd be so grateful! Thanks in advance

Linking from & to in domains and sub-domains
What's the best optimised linking between sub-domains and domains? And every time we'll give website link at top with logo...do we need to link sub-domain also with all it's pages? If example.com is domain and example.com/blog is sub-domain or sub-folder... Do we need to link to example.com from /blog? Do we need to give /blog link in all pages of /blog? Is there any difference in connecting domains with sub-domains and sub-folders?

Competitors ranking with multiple sub-domains with no backlinks
Hi Moz, We are currently doing SEO for a hand therapy company called the Hand Therapy Group. They rank well, however, one competitor, Sydney Hand Therapy, is ranking higher than them for the term "hand therapy Sydney" (which is one of our highly focused keywords) with three different URLs (their home page, contact page and about page) despite the latter two pages have no backlinks. I understand why Google might see their homepage as being more relevant because their name is Sydney Hand Therapy (even though the Hand Therapy Group have more backlinks) but why do the other two URLs rank so well? Any help/info/advice would be brilliant! Cheers!

Website with only a portion being 'mobile friendly' -- what to tell Google?
I have a website for desktop that does a lot of things, and have converted part of it do show pages in a mobile friendly format based on the users device. Not responsive design, but actual diff code with different formatting by mobile vs desktop--but each still share the same page url name. Google allows this approach. The mobile-friendly part of the site is not as extensive as desktop, so there are pages that apply to the desktop but not for mobile. So the functionality is limited some for mobile devices, and therefore some pages should only be indexed for desktop users. How should that page be handled for Google crawlers? If it is given a 404 not found for their mobile bot will Google properly still crawl it for the desktop, or will Google see that the url was flagged as 'not found' and not crawl it for the desktop? I asked a similar question yest, but it was not stated clearly. Thanks,Ted

301 Redirecting multiple domains to brand new domain
Hi guys, I have read quite a bit of stuff on 301 redirects after Penguin. Hoping someone could help me out. im looking at a way to do a legit 301 redirect without passing the penalty. I have acquired two businesses, business1 and business2, that both had websites that were hit by penguin. Ive anaylsed there backlinks and theres a lot of spammy forum links and comments and I was also informed they were both using buildmyrank. A side note, buiness2 only started using BMR after it noticed business1 have large amounts of high PR links. business1.com was ranking at position 1 till the penguin hit. Business2.com was ranking around page 2 I work in the same arena as these two businesses and didnt generate any business via the internet. When these 2 businesses failed (due to loss of rankings and traffic) i decided to take them over. What I am thinking of doing is 301'ing both business domains to my brand new, zero links, domain which will be the name of my new company. I will combine the content from both sites, around 1000 pages, in to the new one. So my question is, does 301'ing multiple domains, that target the same keywords, and operate in the same niche, look less "spammy" then 301'ing 1 domain? I'm trying to look at it in the eyes of google. It is a legit merging of businesses. Thanks for your help, really appreciate your time
