Domain Names Made Easy

A domain is your website's online home. All websites have unique addresses (these are domain names), and your website should be one of the easiest places for potential users or customers to find your brand. “Google.com”, “Amazon.com”, and “bit.ly” are all examples of domain names.

You can get a domain in two ways:

Registering a new domain - If the name isn't taken, you can register it for a fixed fee. While this is usually an affordable option, it can be exceptionally difficult to find a quality domain with a strong extension that hasn't already been registered.

Buying a premium, brandable domain - If the name has already been registered you may be able to purchase it on a domain name marketplace like Atom.com. Our curated marketplaces offer some of the best domains available to buy, with instant purchase options, payment plans on most domains, and transfer assistance! Start searching now and find your perfect domain.

A domain marketplace is an online platform where users buy, sell, or auction domain names. These platforms connect domain owners with potential buyers and often include tools for negotiation, transactions, and domain appraisal. Atom is one of the most popular domain marketplaces, known for its streamlined user experience, curated listings, and branding-focused approach.

Atom offers great, brandable domains, curated so that you can find the perfect fit quickly and easily. We list a variety of domains across our marketplaces, including premium domains, ultra-premium domains, strong domains with alternative extensions, and domains with trusted local TLDs.

An ultra-premium domain is a top-tier, highly valuable domain. Usually, they're single words matched with a .com extension. Comparing domains to real estate, an ultra-premium domain would be a beach-front Malibu property! These domains are extremely easy to remember, very brandable, easy to optimize for SEO and AI discovery, and more. They're a rare business asset and they also tend to hold a high resale value over time.

Use a domain marketplace instead of a registrar to access premium, pre-owned domains not available through standard registrars. This benefits buyers seeking high-value or brandable domain names.

The best domain name marketplace depends on your budget, target market, and the quality of domains you're buying or selling. One of the best domain marketplaces is Atom due to its large, curated inventory, trusted reputation within the domain investment industry, and AI-powered tools that help connect buyers with brandable domains more efficiently. In 2025, Atom further reinforced its leadership in the domain marketplace industry by receiving the prestigious 2025 Trailblazer Award from the Internet Commerce Association, recognizing its innovation, transparency, and positive impact on the domain name ecosystem.

Buy a domain name on Atom's marketplace by searching for a name, selecting a domain, and completing checkout with secure payment. Atom provides fast transfers, optional logo designs, and support throughout the process. Most domains have fixed prices, while some allow payment plans.

A domain extension is the final part of a domain name. Common examples include .com, .net, and .ai. Extensions are also called top-level domains or TLDs. While .com is the gold standard, there's no single “right” domain extension, the best choice for you and your business will depend on your needs, location, industry, budget, and more. Explore your options across the Premium Marketplace, the Sapphire Marketplace for alternative extensions, our ccTLD Marketplaces, or, for world-class single-English-word and category-defining domains, visit the Ultra Premium Marketplace.

Sell a domain name on Atom's marketplace by submitting it for review and setting a price. Once approved, Atom lists the domain, handles buyer communication, and manages secure payment and transfer. Sellers receive payment after successful transfer.

A domain's value is determined by factors like keyword quality, length, brandability, extension, search volume, and past sales data. Short, memorable, and keyword-rich domains in popular extensions (such as .com and .ai) tend to be worth more, and are generally listed at higher prices on domain marketplaces. Market demand, industry relevance, and comparable sales also influence valuation.
