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

Does redirecting from a "bad" domain "infect" the new domain?
Hi all, So a complicated question that requires a little background. I bought unseenjapan.com to serve as a legitimate news site about a year ago. Social media and content growth has been good. Unfortunately, one thing I didn't realize when I bought this domain was that it used to be a porn site. I've managed to muck out some of the damage already - primarily, I got major vendors like Macafee and OpenDNS to remove the "porn" categorization, which has unblocked the site at most schools & locations w/ public wifi. The sticky bit, however, is Google. Google has the domain filtered under SafeSearch, which means we're losing - and will continue to lose - a ton of organic traffic. I'm trying to figure out how to deal with this, and appeal the decision. Unfortunately, Google's Reconsideration Request form currently doesn't work unless your site has an existing manual action against it (mine does not). I've also heard such requests, even if I did figure out how to make them, often just get ignored for months on end. Now, I have a back up plan. I've registered unseen-japan.com, and I could just move my domain over to the new domain if I can't get this issue resolved. It would allow me to be on a domain with a clean history while not having to change my brand. But if I do that, and I set up 301 redirects from the former domain, will it simply cause the new domain to be perceived as an "adult" domain by Google? I.e., will the former URL's bad reputation carry over to the new one? I haven't made a decision one way or the other yet, so any insights are appreciated.

After hack and remediation, thousands of URL's still appearing as 'Valid' in google search console. How to remedy?
I'm working on a site that was hacked in March 2019 and in the process, nearly 900,000 spam links were generated and indexed. After remediation of the hack in April 2019, the spammy URLs began dropping out of the index until last week, when Search Console showed around 8,000 as "Indexed, not submitted in sitemap" but listed as "Valid" in the coverage report and many of them are still hack-related URLs that are listed as being indexed in March 2019, despite the fact that clicking on them leads to a 404. As of this Saturday, the number jumped up to 18,000, but I have no way of finding out using the search console reports why the jump happened or what are the new URLs that were added, the only sort mechanism is last crawled and they don't show up there. How long can I expect it to take for these remaining urls to also be removed from the index? Is there any way to expedite the process? I've submitted a 'new' sitemap several times, which (so far) has not helped. Is there any way to see inside the new GSC view why/how the number of valid URLs in the indexed doubled over one weekend?

Should I redirect a domain we control but which has been labeled 'toxic' or just shut it down?
Hi Mozzers: We recently launched a site for a client which involved bringing in and redirecting content which formerly had been hosted on different domains. One of these domains still existed and we have yet to bring over the content from it. It has also been flagged as a suspicious/toxic backlink source to our new domain. Would I be wise to redirect this old domain or should I just shut it down? None of the pages seem to have particular equity as link sources. Part of me is asking myself 'Why would we redirect a domain deemed toxic, why not just shut it down.' Thanks in advance, dave

Can't generate a sitemap with all my pages
I am trying to generate a site map for my site nationalcurrencyvalues.com but all the tools I have tried don't get all my 70000 html pages... I have found that the one at check-domains.com crawls all my pages but when it writes the xml file most of them are gone... seemingly randomly. I have used this same site before and it worked without a problem. Can anyone help me understand why this is or point me to a utility that will map all of the pages? Kindly, Greg

Can't crawl website with Screaming frog... what is wrong?
Hello all - I've just been trying to crawl a site with Screaming Frog and can't get beyond the homepage - have done the usual stuff (turn off JS and so on) and no problems there with nav and so on- the site's other pages have indexed in Google btw. Now I'm wondering whether there's a problem with this robots.txt file, which I think may be auto-generated by Joomla (I'm not familiar with Joomla...) - are there any issues here? [just checked... and there isn't!] If the Joomla site is installed within a folder such as at e.g. www.example.com/joomla/ the robots.txt file MUST be moved to the site root at e.g. www.example.com/robots.txt AND the joomla folder name MUST be prefixed to the disallowed path, e.g. the Disallow rule for the /administrator/ folder MUST be changed to read Disallow: /joomla/administrator/ For more information about the robots.txt standard, see: http://www.robotstxt.org/orig.html For syntax checking, see: http://tool.motoricerca.info/robots-checker.phtml User-agent: *

Other domains hosted on same server showing up in SERP for 1st site's keywords
For the website in question, the first domain alphabetically on the shared hosting space, strange search results are appearing on the SERP for keywords associated with the site. Here is an example: A search for "unique company name" shows the results: www.uniquecompanyname.com as the top result. But on pages 2 and 3, we are getting results for the same content but for domains hosted on the same server. Here are some examples with the domain name replaced: UNIQUE DOMAIN NAME PAGE TITLE

The page title and meta description on that page is not displayed the same as on the SERP.As far as we can tell, this is the only domain this is occurring for.So far, no crawl errors detected in Webmaster Tools and moz crawl not completed yet.0 -
