Most Popular Domain Extensions & TLDs on the Web

The global domain name base hit 386.9 million registrations at the end of 2025, up 6.2% year over year. Legacy extensions like .COM are massive but slow-growing, while newer gTLDs surged 29.9% in the same period.

Here's how the top gTLDs stack up (Q4 2025, DNIB):

The .COM and .NET base alone is 173.5 million, nearly half of all domains. But the fastest growth is happening elsewhere.

Why .COM Is Still the Default

If the .COM version of your name is available, register it. With ~161 million registrations, .COM accounts for more domains than any other extension by a wide margin. People type it instinctively, email recipients trust it, and when someone can't remember your URL, they'll guess .COM first.

For most small businesses and e-commerce stores, .COM remains the safest choice. With its universal recognition .COM always has strong renewal rates (~75% for .COM/.NET combined), and no audience that will question it.

The only downside: availability. Short, brandable .COM names are hard to find without paying aftermarket prices.

When a Non-.COM TLD Is the Better Move

A non-.COM extension makes sense when the TLD itself communicates something about your brand, not just when .COM is taken.

Choose a newer TLD when:

• Your TLD reinforces your product category. An AI startup on .AI or a retail brand on .STORE tells visitors what you do before they click.
• You want a shorter, more brandable name. "YourBrand.SHOP" sounds better than "YourBrandOnlineStore.COM."
• You're targeting a niche audience that recognizes the extension. Tech communities understand .IO and .DEV. Creatives recognize .DESIGN and .ART.

Stick with .COM when:

• You're building a broad consumer brand where trust matters most.
• Your audience skews older or less tech-savvy.
• You rely on direct type-in traffic or word-of-mouth referrals.

The key question isn't ".COM or not?" — it's whether your TLD adds a brand signal or looks like a consolation prize.

.NET: The Reliable .COM Alternative

.NET is the most recognized alternative when .COM isn't available. It carries a professional, tech-friendly feel and is widely accepted in emails, on business cards, and in browser bars without raising eyebrows.

Best for: Tech companies, online services, and SaaS platforms.

Who uses it: Speedtest.net, Sourceforge.net

.ORG: The Trust Signal for Mission-Driven Brands

.ORG is synonymous with nonprofits, open-source projects, and community organizations. It carries an inherent sense of credibility and public purpose. Anyone can register one, but it's most effective when your brand is built on trust and mission rather than commerce.

Best for: Nonprofits, charities, educational initiatives, and open-source communities.

Who uses it: Wikipedia.org, Craigslist.org

.XYZ: The Startup Wildcard

.XYZ doesn't signal a specific industry, and that's the point. It's versatile, affordable, and popular with tech startups and Web3 projects. It gained mainstream visibility when Google's parent company Alphabet chose it for their corporate site.

Best for: Tech startups, creative projects, and Web3/blockchain ventures.

Who uses it: ABC.xyz, Block.xyz

.TOP: High Volume, Lower Trust

.TOP ranks among the largest gTLDs by registration count, driven largely by bulk registrations and affordability.

Best for: Budget-conscious registrants seeking keyword-rich or short domain names.

Who uses it: Primarily used by smaller sites and regional businesses; few globally recognized brands have adopted .TOP as a primary domain.

.INFO: The Informational Niche

.INFO was built for informational websites: think directories, knowledge bases, and reference resources. It's well-known but carries a mixed reputation due to years of cheap registrations.

Best for: Informational resources, reference sites, and secondary brand domains.

Who uses it: WorldoMeters.info, Spain.info

.SHOP: Instant E-commerce Signal

.SHOP tells visitors exactly what to expect: a place to buy things. The word translates well across languages, giving it strong global appeal. Many companies register their .SHOP domain for merch.

Best for: Online retailers, direct-to-consumer brands, and e-commerce storefronts.

Who uses it: Netflix.shop

.ONLINE: The Digital-First Domain

.ONLINE works across nearly any industry because its meaning is simple: you're on the internet. It doesn't reinforce a specific brand identity the way .AI or .STORE does, but it reads cleanly and feels modern. A neutral, versatile option when .COM isn't available.

Best for: Digital services, online learning platforms, SaaS tools, and businesses emphasizing their web presence.

Who uses it: Casino.online

.STORE: The Brand Storefront

Like .SHOP, .STORE is purpose-built for e-commerce. It tends to feel slightly more formal, think "flagship store" rather than "corner shop." It's a strong choice for brands that want their URL to double as a product destination.

Best for: E-commerce brands, merchandise shops, and product-focused businesses.

Who uses it: DudePerfect.store

.SITE: The Clean, Simple Option

.SITE is a general-purpose extension that essentially means "website." It's neutral, modern, and works for anything: personal portfolios, small businesses, landing pages, or side projects. It doesn't carry strong associations with any industry, which makes it flexible.

Best for: Personal brands, freelancer portfolios, landing pages, and small business sites.

Who uses it: Google previously used business.site for its Google My Business program.

The SEO Question, Answered Plainly

Google treats each TLD equally. The TLD itself is not a ranking factor, with the exception that country-code TLDs (like .UK or .DE) can signal geographic relevance.

So picking .IO over .COM won't hurt your rankings. But there's an indirect effect: user behavior. Domains on familiar extensions get higher click-through rates in search results. Some cheap TLDs like .XYZ have historically attracted spam, making legitimate businesses on those extensions work harder to earn trust.

The bottom line: your TLD won't determine your SEO. Your content, backlinks, and site experience will. But your TLD does shape whether people click.

What TLDs Actually Cost (Registration vs. Renewal)

This is where most guides skip an important detail. First-year registration prices for newer TLDs can be dramatically lower than renewal costs, so plan your costs in advance, for many years ahead.

Here's a snapshot of current pricing on Dynadot:

Prices as of February 2026 via Dynadot's TLD pricing page. Always check for current rates before registering.

Many new gTLDs use aggressive first-year pricing, then charge substantially more at renewal. Budget for year two, not just year one. The DNIB Q4 2025 data underscores this: the average renewal rate for new gTLDs is just 31.3%, compared to ~75% for .COM/.NET. This gap is largely driven by registrants who didn't anticipate the renewal cost.

Frequently Asked Questions

What is the most popular domain extension?

.COM is the most popular domain extension by a wide margin, with approximately 161 million registrations as of Q4 2025. It accounts for roughly 42% of all domain names globally. The next largest gTLDs (.NET and .ORG) are significantly smaller at ~12.5 million and ~10.8 million respectively.

Does my domain extension affect SEO?

No, not directly. Google has confirmed that all generic TLDs are treated equally for ranking purposes. However, your extension can indirectly affect performance through user trust and click-through rates as people are more likely to click on a .COM in search results than an unfamiliar extension. Country-code TLDs (like .UK or .DE) are the one exception, as they can signal geographic relevance to search engines.

Why are some new domain extensions so cheap to register but expensive to renew?

Many new gTLD registries use low first-year pricing as a promotional strategy to drive adoption. The renewal price reflects the actual ongoing cost. For example, .SHOP may cost $1.00 to register but $32.32 to renew.

Should I choose a .COM or a newer extension like .IO or .AI?

Start with .COM if it's available for your brand name as it's universally recognized and trusted. Choose a newer extension only when it actively strengthens your brand message: .AI for an AI company, .STORE for an e-commerce shop, or .DESIGN for a creative studio. Picking a new TLD simply because the .COM was taken often looks like a compromise rather than a deliberate branding choice.

What are the fastest-growing domain extensions right now?

As of Q4 2025, new gTLDs as a category grew 29.9% year over year, far outpacing legacy extensions. Within the top 10 gTLDs, .SHOP, .STORE, .ONLINE, and .SITE all showed strong growth. The .AI extension has also seen significant momentum, driven by the global surge in artificial intelligence startups and products.
