Popular TLD Comparison
When you pick a domain for a new project, the TLD matters more than many people expect. It shapes the trust visitors feel at first glance, drives registration and renewal costs, and even influences click-through rates in search results. This guide lays the popular extensions out side by side across price, use cases, and trust so you can avoid common mistakes.
| TLD | Best For | Reg. Price | Renewal | Trust |
|---|---|---|---|---|
| .com | Universal — all websites | $10-15 | $10-15 | ⭐⭐⭐⭐⭐ |
| .cn | China — mainland China users | $8-12 | $8-12 | ⭐⭐⭐⭐ |
| .net | Network/tech | $10-15 | $10-15 | ⭐⭐⭐⭐ |
| .org | Non-profits, open source | $10-15 | $10-15 | ⭐⭐⭐⭐ |
| .io | Tech companies, SaaS | $30-50 | $30-50 | ⭐⭐⭐⭐ |
| .ai | AI products & startups | $40-80 | $40-80 | ⭐⭐⭐⭐ |
| .co | Startups, business | $15-25 | $15-25 | ⭐⭐⭐ |
| .app | Web/mobile apps | $15-20 | $15-20 | ⭐⭐⭐ |
| .dev | Developer tools | $10-15 | $10-15 | ⭐⭐⭐ |
| .me | Personal portfolio | $15-20 | $15-20 | ⭐⭐⭐ |
| .design | Design studios, creatives | $25-40 | $25-40 | ⭐⭐⭐ |
| .store | E-commerce stores | $25-50 | $25-50 | ⭐⭐⭐ |
| .tech | Tech-related | $10-20 | $10-20 | ⭐⭐⭐ |
| .xyz | New gTLD, many names available | $1-3 | $8-12 | ⭐⭐ |
| .shop | E-commerce (similar to .store) | $20-40 | $20-40 | ⭐⭐⭐ |
The price ranges reflect typical promotional rates across registrars; always confirm at checkout. .io and .ai cost more because of a clear premium on tech and AI audiences — yet in recent years they've become the default choice for SaaS and AI projects.
.xyz often runs ~$1 first-year promos before settling at $8-12 on renewal; you'd pick it mainly for a memorable name and plenty of available options, making it a fit for early-stage projects on a tight budget. .shop is priced close to .store and both target e-commerce. New gTLDs play more promotional games — first-year and renewal prices often differ severalfold — so always check the renewal rate before deciding whether to keep one.
Recommendations by Site Type
| Type | Primary | Alternative |
|---|---|---|
| Business | .com | .net, .co |
| Personal Blog | .com | .me |
| SaaS/Tech | .com | .io, .co |
| AI Product | .ai | .com, .io |
| E-commerce | .com | .store |
| Portfolio | .design | .me, .com |
Recommendations by Target Market
| Market | Primary | Alternative |
|---|---|---|
| Global | .com | .io, .co |
| China | .com + .cn | .cn |
| Europe | .com | .eu |
| US | .com | .io, .co |
For a mainland China audience, .cn or .com.cn adds local trust and makes ICP filing easier; but note that some ccTLDs have eligibility requirements — .de needs a German address and .jp needs local Japanese contact details, so you can't just register them on a whim.
A Selection Example
Say you're building a developer tool site for a global audience. The natural primary is .com (if devtools.com is taken, fall back to .dev or .io). If you're building an AI product, .ai carries brand flair but $40-80 per year in renewals is a long-term cost — when budget is tight, .com or .io is the smarter choice. A domain is costly to change later, so think it through once, carefully.
Pricing and Choosing a Registrar
Domain prices vary a lot — the same extension can differ by more than double between registrars. When choosing a registrar, look at three things:
- Introductory price vs. renewal price: many registrars charge $2 the first year and $15 on renewal, so always check the renewal rate;
- Whether privacy protection is included: confirm it's free and stays free, to avoid hidden charges;
- Whether transfers are smooth: as long as you have the ICANN transfer code (EPP Code) you can move freely — don't get locked in.
A common approach is comparing prices online or checking a few major registrars' official pages directly. For .com, the registry operator Verisign publishes wholesale price adjustment notices each year.
Frequently Asked Questions
Q: My target name is taken under .com — what now?
A: Don't jump to a different extension right away. Check whether it's in a tradeable state (parked, at auction), or differentiate by extension — for example, the main site on .com and the product brand on .io. Many well-known products use exactly this "main site .com + product site new TLD" combination.
Q: Are new extensions like .xyz or .shop worth using?
A: They're cheap and offer plenty of available names, but trust varies. Be cautious with consumer-facing businesses; they're more accepted by developers and younger audiences.
Q: Does the extension affect email deliverability?
A: A few TLDs with a spam history are blocked by default by mailbox providers, so recipients never get your mail. For business use, prefer reputable extensions and send through a professional email service.
Q: Won't registering several TLDs for brand protection get expensive?
A: Each extension is only a dozen or so dollars a year — far cheaper than fighting over a squatted brand. If budget is really tight, at least secure the .com and add others as needed.
Important Notes
SEO Impact
Google treats all TLDs equally, and .com has no direct SEO advantage. But user behavior (preferring .com clicks) can indirectly affect click-through rate, and CTR is one of the ranking signals. New gTLDs (like .xyz or .top) have no natural SEO disadvantage, yet some users trust them less, which can hurt conversion.
Brand Protection
If budget allows, register multiple TLDs:
- Core: .com (must register)
- Protection: .net, .org, .io
- Prevent typosquatting: common misspellings
TLDs to Avoid
- Free subdomains (.tk, .ml) — bad for SEO and brand;
- Some obscure ccTLDs — renewal prices can spike; a $2 registration turning into a $60 renewal is not rare;
- TLDs with spam history (.work, .date, .loan) — many mailbox providers block them by default, so your mail never reaches the inbox.
