Editor’s word: Updated June 2020.
Your web site is a bit like an iceberg. People actually solely ever see essentially the most seen parts – your homepage, blogs, product pages, and so on.
However, there may be a a lot bigger underbelly; a internet of metadata, XML sitemaps, schema markup, and website structure that present the framework producing a sturdy search presence. If you don’t need your search efficiency to go down just like the Titanic, you want to account for these items.
The guts of any web site are a complicated internet of pages and a number of subdomains, and the construction of these parts is essential to SEO success. Google’s algorithms are infamously finicky, so that you don’t need to go shifting round your website map with out first understanding how these adjustments will influence your website’s rating, particularly in relation to your root area versus your subdomains.
One of essentially the most frequent questions our tech staff hears is, “Exactly what’s a subdomain?” An necessary query, to make certain. The extra urgent followup, although, ought to be, “When is the most effective time to make use of them?”
What is a subdomain?
First issues first, there’s a lot of confusion on the market concerning what distinguishes important domains and subdomains. In some instances folks will conflate the 2, however relaxation assured they’re fully completely different.
Your important area – also referred to as a main area or a root area – is basically the identify of your web site. Now, earlier than kicking off an argument round semantics, understand that definition comes immediately from Google itself. How are you able to argue with that?
In Brafton’s case, our important area identify is brafton.com. Notice I didn’t say www.brafton.com or https://www.brafton.com, that are technically our website URLs.
A subdomain is a division of your web site that you simply need to distinguish with its personal distinctive identification and content material. For occasion, if Brafton wished to create a subdomain for our weblog web page (we don’t), our subdomain identify can be weblog.brafton.com.
Why separate sure areas of your web site into subdomains? Let’s take a take a look at an instance of a website hierarchy:
That diagram is fairly clear-cut and straightforward to comply with, proper? But let’s say as an alternative of a easy FAQ web page, you need to construct out an in depth analysis library full of white papers, datasheets, coaching supplies, consumer guides and product operation directions. All of a sudden, that good, neat sitemap would get very sophisticated, very quick.
A subdomain helps you to separate parts of your website which might be intensive sufficient to warrant their very own devoted hierarchy with out going by the entire hassle of establishing a new website with a new area or complicated guests with a fully completely different root area.
Many firms use subdomains on this trend, even Google itself. If you want help with any of the tech big’s apps, you’ll be directed to this web page:
Notice that it’s not https://google.com/support, however https://support.google.com. That ordering is essential to distinguishing a subdomain from a subfolder. Unlike a subdomain, a subfolder branches off from the top-level area within the website hierarchy.
Site hierarchy finest practices stress the significance of simplicity, recommending that organizations decrease the variety of classes and subcategories included in any navigation sitemap. Kissmetrics, for example, suggests preserving the number of site categories restricted to wherever from two to seven.
Second-level domains are mainly the identical as a subdomain, proper?
Lord, no. Despite the nomenclature, the second-level area is arguably a very powerful a part of your important website identify. That’s as a result of top-level and second-level domains truly discuss with the hierarchy of internet addresses, not how they relate to your important web site.
Again, take brafton.com. In this case, “.com” is the top-level area (TLD), indicating that the positioning is a industrial web site. Web tackle suffixes like .org, .edu and .gov are all top-level domains. Your area TLD may additionally reference the positioning’s nation: .ca, .it, .in, .uk, and so on. We’re actually speaking in regards to the constructing blocks of internet sites right here.
With that in thoughts, “brafton” is the second-level area. And actually, that’s what folks bear in mind and affiliate together with your important website. No one calls Google “google.com” or LinkedIn “linkedin.com.” That can be loopy.
How do you arrange a subdomain?
There are mainly two methods to create a subdomain: utilizing a CNAME document or an A document. CNAME is a document that resolves to another URL, whereas an A document resolves to an IP tackle.
Regardless of which method you are taking, the document must be created in line with your subdomain’s internet hosting specs. If you don’t comply with these internet hosting specs, you run the chance of establishing a DNS document that gained’t correctly resolve when the internet hosting account receives requests from it. With that in thoughts, it could possibly be a good concept to seek the advice of your area supplier (aka, your internet hosting supplier, or extra merely, “area host”) to get all of the internet hosting info you’ll want and take away any guesswork from the equation.
How does all of this look in motion? Let’s say you’re internet hosting by WP Engine and need to arrange a devoted web site subdomain to your weblog. You’ll must undergo an internet portal that appears one thing like this:
When you go to create a subdomain, WP Engine will concern you a short-term URL to make use of. From there, you may select to create both a CNAME document to resolve again to that URL or an A document to resolve your new weblog to a particular IP tackle.
Finally, you’ll must register your new subdomain with WP Engine so it is aware of methods to correctly resolve it.
When does it make sense to make use of subdomains?
Given how intensive Google’s help web page is, it’s a good candidate for subdomain standing: There are a dozen apps to cowl, every with distinctive troubleshooting articles and consumer guides.
Subdomains are additionally fairly important if your organization operates in numerous worldwide markets and you need to arrange distinct web sites geared towards sure nations and areas. If your German clients are compelled to navigate the identical web site as your clients in North America (in English, thoughts you), that’s not going to result in a nice model expertise. A subdomain saves you the difficulty of getting to purchase a new area for every nation.
In a comparable trend, subdomains are helpful whenever you truly need to create a completely different model expertise for customers. For occasion, when firms have completely different merchandise and providers for each client and enterprise audiences. If you need to create distinct e-commerce websites for each B2C and B2B audiences (Amazon, for instance, has a separate Amazon Business website for B2B customers. Although it’s not a subdomain.), a subdomain could possibly be a good possibility.
Comcast Business is a nice instance of how subdomains help a higher model expertise. Those providers are particularly geared towards a B2B viewers and are pretty intensive, so it wouldn’t make sense to bury that info someplace in Comcast’s main, consumer-focused website. The https://business.comcast.com/ subdomain permits Comcast to create two separate model experiences for 2 very completely different goal audiences whereas utilizing the identical area identify.
Companies may additionally use subdomains to set up mobile-focused variations of their important web sites. Obviously, navigating a internet web page could be very completely different on a smartphone or pill than a desktop PC. Adaptive improvement processes dictate that builders account for various display sizes and type elements when designing cell web sites. Creating a separate subdomain permits companies to offer an intuitive consumer interface for each desktop and cell website guests.
What are the SEO implications of subdomains?
“So, it’s a good organizational software,” you could be asking your self, “however what does a subdomain need to do with SEO and natural rankings?” Excellent query.
First of all, there’s actually no such factor as group for group’s sake in relation to website construction and hierarchy. A web site that’s complicated to navigate on account of poor construction goes to inevitably get dinged by engines like google. A foul website format will result in guests spending much less time in your web page or extra time on the web page if it takes them a very long time to search out what they’re searching for, leading to a lower than passable expertise and doubtlessly hurting your search efficiency.

There has been a lot of discuss on the market in regards to the potential adverse influence that subdomains can have on SEO efficiency, particularly that engines like google penalize them or have issue parsing between important domains and subdomains.
The reasoning goes that Google’s algorithms will acknowledge your subdomains as websites separate out of your important area, and rank them individually. They’ll primarily be stranded on little SEO islands, and your web site gained’t profit from any constructive influence your subdomain would in any other case present if it had been a subdirectory as an alternative.
Although the controversy on subdomains’ SEO deserves – or lack thereof – rages on, there’s motive to imagine that earlier warnings of “natural search cannibalization” might have been a tad overstated.
In an August 2016 Hangout session, Google Webmaster Trends Analyst John Mueller addressed the question head-on, stating that subdomains typically don’t harm website rankings:
“[W]e acknowledge that some websites use subdomains as completely different components of the positioning,” he mentioned. “And, in the identical approach that different websites would possibly use subdirectories.”
According to Mueller, Google’s algorithms are fairly adept at crawling subdomains and subdirectories equally properly and making sense of all of it.
That being mentioned, he did warning towards using wildcard subdomains designed to redirect anybody attempting to entry non-existent subdomains to a particular folder. Google’s algorithms have traditionally had issue crawling these particular sorts of subdomains.

Like nearly every thing else associated to SEO and Google rating elements, it’s a must to take issues on a case-by-case foundation. There’s no set rule dictating using subdomains as a result of, for some firms, their advantages will outweigh any potential SEO fallout (both actual or perceived).

John Doherty, founding father of the skilled SEO and digital advertising supplier community Credo, explains that to get the most SEO value out of your subdomain, you want to deal with them as in the event that they’re their very own full-fledged web sites.
“Subdomains can completely be made to work properly for SEO, nevertheless it requires a lot of additional effort over placing the content material (equivalent to a weblog) in a subfolder,” Doherty says. “We have seen many occasions that when content material (equivalent to a weblog) is moved from a subdomain to a subfolder that always a dramatic improve in natural visitors and rankings happens. This is tougher to do, and perhaps even unimaginable, relying on the aim of the subdomain, however is one thing to be thought-about when launching a subdomain within the first place.”
