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.

What are best page titles for sub-domain pages?
Hi Moz communtity, Let's say a website has multiple sub-domains with hundreds and thousands of pages. Generally we will be mentioning "primary keyword & "brand name" on every page of website. Can we do same on all pages of sub-domains to increase the authority of website for this primary keyword in Google? Or it gonna end up as negative impact if Google consider as duplicate content being mentioned same keyword and brand name on every page even on website and all pages of sub domains? Thanks

Why is my domain authority still 1?
I changed the domain of my website from www.vanillacrush.co.uk to www.carissamay.co.uk at the end of December and yet my DA for carissamay is still 1. As advised, I set up a 301 redirect from VC to CM which seems to be working fine. However when I check on redirect detective it tells me I also have a 302 set up. Could this be confusing things? http://www.vanillacrush.co.uk

How Can I Redirect an Old Domain to Our New Domain in .htaccess?
There is an old version of http://chesapeakeregional.com still floating around the web here: http://www.dev3.com.php53-24.dfw1-2.websitetestlink.com/component/content/category/20-our-services. Various iterations of this domain pop up when I do certain site:searches and for some queries as well (such as "Diagnostic Center of Chesapeake"). About 3 months ago the websitetestlink site had files and a fully functional navigation but now it mostly returns 404 or 500 errors. I'd like to redirect the site to our newer site, but don't believe I can do that in chesapeakeregional.com's .htaccess file. Is that so and would I need access to the websitetestlink .htaccess to forward the domain? Note* I (nor anyone else in our organization) has the login for the old site. The new site went live about 9 months before I arrived at the organization and I've been slowly putting the pieces together since arriving.

Too many backlinks from one domain?
I've been in the process of creating a tourism-based website for the state of Kansas. I'm a photographer for the state, and have inked a nice little side income to my day job as a web designer by selling prints from Kansas (along with my travels elsewhere). I'm still in the process of developing it, but it's at least at a point that I need to really start thinking about SEO factor of the amount of backlinks I have from it going back to my main photography website. The Kansas site is at http://www.kansasisbeautiful.com and my photography website is http://www.mickeyshannon.com. This tourism website will serve a number of purposes: To promote the state and show people it's not just a flat, boring place. To help promote my photography. The entire site is powered by my photography. To sell a book I'm planning to publish later this year/early next year of Kansas images. To help increase sales of photography prints of my work. What I'm worried about is the amount of backlinks I have going from the Kansas site to my photography site. Not to mention every image is hosted on my photography domain (no need to upload to two domains when one can serve the same purpose). I'm currently linking back to my site on most pages via a little "Like the Photos? Buy a print" link in the top right corner. In addition, when users get to the website map, all photo listings click back to a page on my photography site that they can purchase prints. And the main navigation also has a link for "Photos" that takes them to my Kansas photo galleries on my photography website as well. The question I have: Is it really bad SEO-wise to have anywhere from 1 to 10+ backlinks on every page from one domain (kansasisbeautiful.com) linking back to mickeyshannon.com? Would I be better served moving all of the content from kansasisbeautiful into a subdirectory on my photography site (mickeyshannon.com/kansas/) and redirecting the entire domain there? I haven't actually launched this website yet, so I'm trying to make the right call before pushing it to the public. Any advice would be appreciated!

New Site: Use Aged Domain Name or Buy New Domain Name?
Hi,
Intermediate & Advanced SEO | | peterwhitewebdesign
I have the opportunity to build a new website and use a domain name that is older than 5 years or buy a new domain name. The aged domain name is a .net and includes a keyword.
The new domain would include the same keyword as well as the U.S. state abbreviation. Which one would you use and why? Thanks for your help!0
