Domain vs URL, no, it’s not the title of Marvel’s next blockbuster. It’s a question on everyone’s lips, or at least it is when they’re starting a business and realize that a strong web presence is essential for building a successful brand.

More than a quarter of all business is conducted online as of 2024. Whether you’re selling a digital marketing toolkit to a tech-savvy audience or yoga mats and bone broth to digital detoxers, a website is more important than ever.

But for many business founders (particularly those selling bone broth, maybe), the internet is a complicated place. That leads to some questions.

Namely, what is the difference between domain vs URL? So let’s find out.

What is a Domain Name?

A domain name, or just “domain,” is a unique address that leads internet users to a website. Our domain name is Atom.com. Domain names are made up of two parts: a memorable “name” like Atom, Google, or Harvard and an extension like .com, .org, or .edu (in the case of Harvard.edu).

Memorability is key. We use domain names because they make it easy for humans to remember and access websites. When you need to search the web, you type Google.com, and when you need a business name, you type Atom.com.

Every domain name is matched with an equally unique IP address (and sometimes more than one for really popular websites like Google). IP addresses are what your computer browser uses to find a website, and they are made up of long sequences of numbers like 198.112.534.7. Domain names are the human side of web addresses, while IP addresses are the computer side.

So, a domain name and an IP address both refer to the website in different ways. Think of a domain name like a street address (123 Main Street) and an IP address like a set of GPS coordinates. They may refer to the exact same address, but you’ll remember the street address for postcards, not the GPS coordinates.

Domain vs URL: What’s the Difference?

URL stands for Uniform Resource Locator. While a domain name refers to a website as a whole, a URL refers to the specific page of a website.

Imagine if 123 Main Street wasn’t a whole home but a block of flats, and you wanted to send a postcard to your friend in apartment 13F. The full address would then be 13F, 123 Main Street. This new address would now point to a particular place inside the whole apartment block, like a particular page on a website.

Domains and URLs look similar and can sometimes be confusing because the main landing page of a website will be https://www.Atom.com. This is the full URL of the domain name Atom.com. Our browsers will add the transfer protocol (https://) and subdomain www automatically, translating a domain name into a URL.

Officially, a URL will include the protocol (like http:// or https://). It also includes any further path (such as /en/blog) and potentially a subdomain like mail or blog.

• Atom.com is a domain
• https://www.Atom.com is a URL
• https://www.atom.com/blog/what-is-a-domain-name is a URL.
• hubspot.com is a domain.
• https://blog.hubspot.com/ is a URL

Domain vs URL Anatomy

As we’ve said, a domain name comprises two parts: the brandable, memorable name and an extension (or top-level domain) like com. Every URL contains a domain, but since most URLs point to a particular web page on a website, they include a few more elements. Let’s zoom in on the makeup of a URL.

• Transfer protocol: The transfer protocol or scheme is the first part of a URL. Nowadays, most URLs use a transfer protocol, “https://” which replaced the less secure HTTP.  HTTPS stands for  “Hypertext Transfer Protocol Secure” and provides web browsers with information about how the website is loaded.

• Top-level domains: The top-level domain (TLD), also known as the extension, the .org, or .com part of a domain name. These indicate that the domain is managed by a particular regulatory body called a registry. There are over 1600 TLDs, including country-specific ccTLDs like .fr, .ru, and .mx, and those reserved for particular types of organizations like government departments (.gov) and education institutions (.edu).

• Second-level domains: The second-level domain (SLD or 2LD) can be ambiguous because it is whatever immediately precedes the TLD. This is often the name of the website itself (as in Google.com and Atom.com), but certain extensions have a second-level hierarchy to them. For example, in the URL https://www.guardian.co.uk, the extension is .co.uk, making .co is the SLD (note that .co can also be an independent TLD and is the ccTLD for Colombia).

• Subdomains: Subdomains are used to indicate significant subsections of a website and come before the name portions of the domain, like the blog in “blog.hubspot.com”. www is itself a subdomain, but it’s so ubiquitous that domain registrars include it in domain sales, and web browsers can navigate without it.

• Subdirectory and Path: The latter parts of a URL that come after the TLD lead the browser to particular web pages. In the URL https://www.atom.com/blog/domain-redirection, /blog is a subdirectory that leads to a folder, and /domain-redirection is the path to a page.

https:// www. Atom .com /blog /domain-redirection

Wrapping Up

Okay, domain vs URL isn’t the battle of the century. However, the difference between a domain and a URL is important to understand.

Choosing your domain name is a big decision and will impact the future branding of your business. Meanwhile, choices about your URL (subdomain, subdirectory, and path) are important in SEO.

Before you can make those choices, you need a powerful domain name that inspires trust and confidence in consumers. Atom’s Premium Domains Marketplace is curated by naming experts, matching strong, brandable names with credible extensions.
