Moz Q&A is closed.
After more than 13 years, and tens of thousands of questions, Moz Q&A closed on 12th December 2024. Whilst we’re not completely removing the content - many posts will still be possible to view - we have locked both new posts and new replies. More details here.
When creating a sub-domain, does that sub-domain automatically start with the DA of the main domain?
-
We have a website with a high DA and we are considering sub-folder or sub-domain. One of the great benefits of a sub-folder is that we know we get to keep the high DA, is this also the case for sub-domains?
Also if you could provide any sources of information that specify this, I can't see to find anything!

I would go with a sub-folder if passing DA is your goal. As far as I understand it, DA is not considered by Moz for sub-domains. Here is a similar post on the same topic. I hope it helps.

**Also, although I would also be curious to know if a subdomain inherits DA from the main domain, it probably doesn't need to be a part of the decision making process for choosing between subdomain and subfolder. **
I know that the sub & parent share the same DA. I was under the impression that one doesn't necessarily inherit the other DA, just an accumulation of the "strength" calculated by Moz of the domain shared between the parent & subs.

I agree with EGOL, if you have the choice, use subfolders instead of subdomains.
I know sometimes, there are development reasons why a company decides to move forward with subdomains. And those can rank just fine too. It's just best to let decision makers know that the SEO department is voting for subfolders.
Also, although I would also be curious to know if a subdomain inherits DA from the main domain, it probably doesn't need to be a part of the decision making process for choosing between subdomain and subfolder. As EGOL said, "ranking ability and DA are different things", so the DA passed through or not passed through to a subdomain will not be the reason for ranking well or not in Google.

In the question between a subfolder and a subdomain... it is clear and it is murky...
Search engines say things and often do the things that they say. They also do things without sayin' that they did them and you are left to figure out what happened or how things work on your own.
If you have been running websites for a long time (24 years here), you might know that Google and other search engines have treated subdomains and folders differently, identically and murkily. It depends upon what year and month you are talking about.
**The constant is that subfolders have always inherited ranking ability from their parent domain, and will likely do that into the future. **
So, if you want assurance into the future, using a subfolder is your best bet.
Looking at DA... it is irrelevant in the subdomain and subfolder discussion. DA is a moz number that kinda correlates with search engine rankings, but just part of the time. Ranking ability and DA are different things.

Move domain to new domain, for how much time should I keep forwarding?
I'm not sure but my website looks like is not getting it's juice as supposed to be. As we already know, google preferred https sites and this is what happened to mine, it was been crawling as https but when the time came to move my domain to new domain, I used 301 or domain forwarding service, unfortunately they didn't have a way to forward from https to new https, they only had regular http to https, when users clicked to my old domain from google search my site was returned to "site does not exist", I used hreflang at least that google would detect my new domain been forwarding and yes it worked but now I'm wondering, for how much time should I keep the forwarding the old domain to the new one, my site looks like is not going up, I have changed all the external links, any help would be appreciated. Thanks!

Does having a different sub domain for your Landing Page and Blog affect your overall SEO benefits and Ranking?
We have a domain www.spintadigital.com that is hosted with dreamhost and we also have a seperate subdomain blog.spintadigital.com which is hosted in the Ghost platform and we are also using Unbounce landing pages with the sub domain get.spintadigital.com. I wanted to know whether having subdomain like this would affect the traffic metric and ineffect affect the SEO and Rankings of our site. I think it does not affect the increase in domain authority, but in places like similar web i get different traffic metrics for the different domains. As far as i can see in many of the metrics these are considered as seperate websites. We are currently concentrating more on our blogs and wanted to make sure that it does help in the overall domain. We do not have the bandwidth to promote three different websites, and hence need the community's help to understand what is the best option to take this forward.

Should I redirect my Google Update Effected Domain to brand new Domain?
Hey Moz experts, I had a domain which was really doing better but after the Humming Bird update my traffic was decreased up to 90%. There are plenty of posts on my existing blog, Now what should I do? I mean should I redirect it to a brand new domain or Copy all the posts to a brand new domain and delete my existing domain? Note that the Old domain has PR1, DA 19 and PA 30.

Is it safe to redirect our .nl (netherlands) domain that we have just purchased to our .com domain?
Hi all! We've recently developed a German version of our website with German translation and now we have just purchased a .nl domain, but with this one, we want all of the copy to remain in English. Is it ok to redirect our .nl domain to our current .com website or will this give us bad SEO points? Thank you!

Is it safe to 301 redirect old domain to new domain after a manual unnatural links penalty?
I have recently taken on a client that has been manually penalised for spammy link building by two previous SEOs. Having just read this excellent discussion, http://www.seomoz.org/blog/lifting-a-manual-penalty-given-by-google-personal-experience I am weighing up the odds of whether it's better to cut losses and recommend moving domains. I had thought under these circumstances it was important not to 301 the old domain to the new domain but the author (Lewis Sellers) comments on 3/4/13 that he is aware of forwards having been implemented without transferring the penalty to the new domain. http://www.seomoz.org/blog/lifting-a-manual-penalty-given-by-google-personal-experience#jtc216689 Is it safe to 301? What's the latest thinking?

Noindex, Nofollow to previous domain
Hi, My programmer recently did a horrible mistkae by adding noindex, nofollow to our website without me noticing for two days. At the same time he did it we bought a new domain and redirected the old domain to the new domain: The Old domain is: http://www.websitebuildersworld.com and the new one is: http://www.websiteplanet.com Now unfortunatly I didn't notice the noindex,nofollow when it was on the old domain and I redirected it to websiteplanet.com before I fixed the noindex, nofollow. I fixed the problem around 10 hours ago on the new domain (www.websiteplanet.com) but the old domain didn't get indexed back (yet), so for example if you search for WebsiteBuildersWorld in google you will not reach the homepage as google deleted it because of the noindex,nofollow. My question is:
Intermediate & Advanced SEO | | Ouzan
Do you think that it will be fixed and google will retrieve websitebuildersworld homepage to his search results and then redirect it to websiteplanet? Or because I redirected websitebuildersworld.com to websiteplanet.com before letting google crawling websitebuildersworld.com without the noindex,no follow it wouldn't get indexed again? I hope I explained the problem good enough. Looking forward for your valuable replies. Thanks.0 -
Domain expiration and seo
My domain name is free with my service with yahoo but it expires every year and gets extended automatically as I continue service, how does this impact my seo efforts? I've heard that the search engines prefer sites to expire in 3 years or more? Is this a fact?
