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.

Is there any significant benefit to creating online directory listings that only provide nofollow links to our domain?
Is there any significant benefit to creating online directory listings that only provide nofollow links to our domain? For context, whilst doing link gap analysis I've found our competitors are listed on local government directories such as getsurrey.co.uk and miltonkeynes.co.uk. Whilst these aren't seen as spam directories, it's still highly unlikely we'll receive much traffic through them. The links they provide to our domain have the nofollow tag. So I wonder whether there's any other benefit to investing the time in creating these listings? Would be interested to hear your thoughts Many thanks in advance

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!

Buying a domain banned by google
Hi , I came across a super domain for my business but found out that it was a great domain with 100s of link backs but is now banned by Google search engine meaning Google does not index content from that domain. Since the domains linkbacks are from my domin does it make sense to but that domain and redirect those link backs to another (301) and hope that the new domain gets some juice ... I know it is sounding crazy and may not be the best thing to do ethically but still wanted to check if its possible to get some juice.. Rgds Avinash

Primary Domain or Redirect?
We are starting a new travel guide for a resort town. I have bought an expired domain with decent related links and PR (which seems to have survived the transfer (4 months ago). Beofre we launch the new site I am trying to decide if we should use this expired domain as the primary URL for the new site or just do a permanent redirect and buy a new domain that better matches the theme of the site. I am obviously concerned with starting from scatch with a new domain. I am confident we can build some good rellevant links in a short time but this space is very competetive. Any input would be greatly appreciated.

Hosting images on multiple domains
I'm taking the following from http://developer.yahoo.com/performance/rules.html "Splitting components allows you to maximize parallel downloads. Make sure you're using not more than 2-4 domains because of the DNS lookup penalty. For example, you can host your HTML and dynamic content on www.example.org and split static components between static1.example.org and static2.example.org" What I want to do is load page images (it's an eCommerce site) from multiple sub domains to reduce load times. I'm assuming that this is perfectly OK to do - I cannot think of any reason that this wouldn't be a good tactic to go with. Does anyone know of (or can think of) a reason why taking this approach could be in any way detrimental. Cheers mozzers.

Move blog from subdomain to main domain on ecom site?
I am wondering what my fellow mozers think. Pretty set about my direction but want to get any other input to aid in my decision. Have an ecom site with a www.blog.maindomain.com. The blog is fairly new and no major rankings. There are only about 30 posts. This isn't a super competitive market and the blogging won't be a huge part of our content strategy but I would like to use it for passing juice etc. Would you go through the trouble to move the blog to www.site.com/blog and redirecting all the old content to new?
