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.

Sub Domain Usage
I see that the gap uses gap.com, oldnavy.gap.com and bananarepublic.gap.com. Wouldn't a better approach for SEO to have oldnavy.com, bananarepublic.com and gap.com all separate? Is there any benefit to using the approach of store1.parentcompany.com, store2.parentcompany.com etc? What are the pros and cons to each?

Microsites: Subdomain vs own domains
I am working on a travel site about a specific region, which includes information about lots of different topics, such as weddings, surfing etc. I was wondering whether its a good idea to register domains for each topic since it would enable me to build backlinks. I would basically keep the design more or less the same and implement a nofollow navigation bar to each microsite. e.g.
Intermediate & Advanced SEO | | kinimod
weddingsbarcelona.com
surfingbarcelona.com or should I rather go with one domain and subfolders: barcelona.com/weddings
barcelona.com/surfing I guess the second option is how I would usually do it but I just wanted to see what are the pros/cons of both options. Many thanks!0 -
Community inside the domain or in a separate domain
Hi there, I work for an ecommerce company as an online marketing consultant. They make kitchenware, microware and so on. The are reviewing their overall strategy and as such they want to build up a community. Ideally, they would want to have the community in a separate domain. This domain wouldn't have the logo of the brand. This community wouldn't promote the brand itself. The brand would post content occassionally and link the store domain. The reasoning of this approach is to not interfere in the way of the community users and also the fact that the branded traffic acquired doesn't end up buying at the store I like this approach but I am concerned because the brand is not that big to have two domains separated and lose all the authority associated with one strong domain. I would definitely have everything under the same domain, store and community, otherwise we would have to acquire traffic for two domains. 1. What do you think of both scenarios, one domain versus two? Which one is better? 2. Do you know any examples of ecommerce companies with successful communities within the store domain? Thanks and regards

Domain Forwarding - SEO Impacts?
I have a site that has been active for years - thinkbiglearnsmart.com. Awhile ago I had purchased about 50 domain names that were relevant to my company. I still have those urls and would like to use them to point to different pages on my site - just because they have good key words in the URLs. For example - one is dreamweavertrainingclassesonlinelive.com. Currently they are all redirecting to my homepage. A. is that hurting me? B. I would like to redirect to the more relevant page. ie the page dedicated to Dreamweaver training (http://thinkbiglearnsmart.com/dreamweaver-creative-cloud-training-course/ ) Will this hurt my Dreamweaver keyword for example because there is already a 301 redirect on that page from a very old Dreamweaver link which was something like thinkbiglearnsmart.com/dreamweaver C. On my hosting account where I can select where the URL forwards to - it has an option for "Location forwarding" and "Frame forwarding" - currently they are set to Frame forwarding - which one is best? Any help is much appreciated!!! Thank you!

Using pictures from another domain
We are building several sites for several clients which will be using images from the manufacturer. Our dev team wants to insert the manufacturer's url for the images, instead of actually downloading the image and hosting on our server. There are thousands of images, so downloading images to our server will be time consuming, so we are looking for a shortcut.... however I'm concerned this will cause other issues. Is using manufactueresdomain.com/12345.jpg going to cause SEO issues? will this generate Google penalties? Since we are not able to control the image file name, we cannot optimize it. We will add Alt text and Title tag for each image, but the file name is random characters. How important is the file name for SEO?

Keep multiple domains or combine them?
I need some help figuring out if I should combine multiple domains or if I should let them be separate? I have domain1.com, domain2.com, and domain3.com. Well, domain1.com owns domain2.com and domain3.com. And currently domain1.com points to domain2.com and domain3.com from the homepage. They are going through some changes at their business, and now the option is on the table to combine the domains or still let them be separate as long as they link to each other. What is the best way to handle this and are there more things I should go through before making a decision? None of them have a ton of links to them, and they aren't super robust, but would just to have some advice. Thanks a lot

Recovery during domain migration
On average, how long does it takes to recover 80% of the rankings if two high authority domains are combined without chaging any content? I totally understand that each domain is different and search engines can treat them differently but if all the steps are followed to the T what are the chances?
