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.

Shopify Site with Multiple Domains?
Hey there! My client has a website on Shopify. I don't even know how to open this can of worms, but let me try. The site URL is: https://mobilityequipmentforless.com/ However, there is another (older?) URL that gets updated as the main site gets updated and shows the exact same content. It's a straight duplicate, but is it's own URL and doesn't redirect to the main site. https://www.powerchairrecyclers.com/ And this isn't the SITE.Shopify back-end site name that was used for set up initially. I just have no idea what's going on here. Not sure if it's a serious error that needs to be fixed, or if it's something weird with how Shopify work. Any insight would be immensely helpful. Thanks! Mike

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.

Is domain authority lost if you create a 301 redirect but mark it as noindex, nofollow?
Hi everyone, Our company sells products in various divisions. While we've been selling Product A and Product B under our original brand, we've recently created a new division with a new domain to focus on a Product B. The new domain has virtually no domain authority (3) while the original domain has some (37). We want customers to arrive on the new domain when they search for key search terms related to Product B instead of the pages that previously existed on our main website. If we create 301 redirects for the pages and content on the main site and add noindex, nofollow tags, will we lose the domain authority that we have from our original domain because the pages now have the noindex, nofollow tags? I read a few blog posts from Moz that said there isn't any domain authority lost with 301 redirects but I'm not sure if that is true if the pages are noindex, nonofollow. Do you follow? 🙂 Apologies for the lengthy post. Love this community and the great Moz team. Thanks, Joe

Legacy domains
Hi all, A couple of years ago we amalgamated five separate domains into one, and set up 301 redirects from all the pages on the old domains to their equivalent pages on the new site. We were a bit tardy in using the "change of address" tool in Search Console, but that was done nearly 8 months ago now as well. Two years after implementing all the redirects, the old domains still have significant authority (DAs of between 20-35) and some strong inbound links. I expected to see the DA of the legacy domains taper off during this period and (hopefully!) the DA of the new domain increase. The latter has happened, although not as much as I'd hoped, but the DA of the legacy domains is more or less as good as it ever was? Google is still indexing a handful of links from the legacy sites, strangely even when it is picking up the redirects correctly. So, for example, if you do a site:legacydomain1.com query, it will give a list of results which includes pages where it shows the title and snippet of the page on newdomain.com, but the link is to the page on legacydomain1.com. What has prompted me to finally try and resolve this is that the server which hosted the original 5 domains is now due to be decommissioned which obviously means the 301 redirects for the original pages will no longer be served. I can set up web forwarding for each of the legacy domains at the hosting level, but to maintain the page-by-page redirects I'd have to actually host the websites somewhere. I'd like to know the best way forward both in terms of the redirect issue, and also in terms of the indexing of the legacy domains? Many thanks, Dan

Consolidating Multiple Domains into A Single Domain
I have a client who's website is an amalgamation of multiple domains. jacksonhole.net is the main domain but the site passes traffic back and forth from the following domains/sites. My questions is, would it it be better for SEO to consolidate all of these domains under the single high authority domain and 301 redirect the rest or is that a really bad idea? Thanks for your help. jacksonhole.net (Domain Authority 31) jackson-hole-rental-condos.com (Domain Authority 22) jackson-hole-rental-homes.com (Domain Authority 21) j acksonholehotelguide.com (Domain Authority 19)

Is it worth creating an Image Sitemap?
We've just installed the server side script 'XML Sitemaps' on our eCommerce site. The script gives us the option of (easily) creating an image sitemap but I'm debating whether there is any reason for us to do so. We sell printer cartridges and so all the images will be pretty dry (brand name printer cartridge in front of a box being a favourite). I can't see any potential customers to search for an image as a route in to the site and Google appears to be picking up our images on it's own accord so wonder if we'll just be crawling the site and submitting this information for no real reason. From a quality perspective would Google give us any kind of kudos for providing an Image Sitemap? Would it potentially increase their crawl frequency or, indeed, reduce the load on our servers as they wouldn't have to crawl for all the images themselves?

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!
