Your domain name is your startup's first impression, permanent address, and part of your brand forever. Most founders spend more time picking a logo color than their domain. Don't be that founder.
This guide gives you a systematic framework for making the decision well — and quickly.
Why Domain Names Matter More Than You Think
Before the framework, let's calibrate on stakes. Your domain name affects:
- Direct traffic: People who remember your name and type it directly
- Word-of-mouth: Whether people can spell and repeat your name accurately
- Email deliverability: A good domain improves sender reputation
- SEO signals: Domain age, authority, and structure all matter
- Investor perception: A premium domain signals seriousness
- Acquisition value: Strong brand domains fetch higher exit multiples
Changing your domain later is painful — you lose SEO equity, confuse existing users, and have to update everything. Get it right the first time.
The 6 Criteria That Actually Matter
Step 1: Define Your Naming Strategy
Before generating names, decide which type of domain you're going for. This shapes everything.
The Three Naming Archetypes
Each has different trade-offs for brand building, SEO, and availability.
Archetype A: Pure Brandable
An invented or unexpected word with no pre-existing meaning. Examples: Stripe, Notion, Figma, Vercel.
Best for: Tech startups with marketing budget. Gives you a blank slate to define the brand.
Archetype B: Suggestive
A real or invented word that hints at the category without describing it literally. Examples: Mailchimp, Dropbox, Zoom, Calendly.
Best for: Most startups. The sweet spot — memorable and self-explanatory.
Archetype C: Descriptive / Keyword
Directly says what you do. Examples: Booking.com, Hotels.com, Insurance.com.
Best for: Local businesses, affiliate sites, or single-focus businesses with SEO as primary acquisition.
Step 2: Generate Candidates
With your archetype chosen, generate 20–30 raw candidates. Don't filter yet — just produce volume.
Generative techniques that work:
- Portmanteau: Blend two relevant words (Pinterest = pin + interest, Spotify = spot + identify)
- Metaphor: What does your product feel like? (Slack = relaxed communication, Arc = a journey)
- Foreign words: Simple words from other languages that sound great in English (Figma is a play on "figma" — a figure/schema)
- Truncation: Shorten a descriptive phrase (Instagram = instant camera + telegram)
- Rhyme and rhythm: Names with internal rhythm are stickier (TikTok, Chime, Zoom)
- Common words, unexpected use: Take an ordinary word and own it (Apple, Stripe, Discord)
Quick exercise: List 5 adjectives that describe how using your product feels. Then 5 nouns from a related but not identical field. Combine them. This often produces great suggestive names.
Step 3: Filter for the 6 Criteria
Run your 20–30 candidates through the six criteria above. Score each 1–3. Keep the top 5–8.
The Radio Test
Imagine someone says your domain name on a radio ad. Could a listener go home and type it correctly? If you'd need to spell it out ("that's K-L-I-M-B, no E"), it fails the test.
The Stranger Test
Say the name to three people who know nothing about your startup. Ask them to spell it back. If more than one person gets it wrong, reconsider the name.
Step 4: Check Availability
For each of your top candidates, check:
- .com availability: The gold standard. Check first.
- Alternative TLDs: .io, .app, .co if .com is taken
- Social handles: Twitter/X, Instagram, LinkedIn — consistency matters
- Trademark database: USPTO TESS for US, EUIPO for Europe
- Existing businesses: Google the name to find any existing companies
The .com Question
Aim for .com if you can. It's the default extension users type. If .com is taken and parked by a squatter, weigh the cost of buying it vs. choosing a different name entirely. Names are usually cheaper to change than domains are to buy from squatters.
Step 5: Test Before You Commit
Before registering and building, run a quick validation:
- Say the name in conversation naturally — does it feel awkward?
- Write an imaginary press headline with the name — does it read well?
- Imagine telling an investor: "We're building [Name]." Does it sound credible?
- Check the domain history at Wayback Machine — was it ever used for spam?
- Reverse-search the name for any unfortunate connotations in other languages
The Domain Name Checklist
- Under 15 characters (excluding TLD)
- No hyphens or numbers
- Passes the radio test — hearable and spellable
- Passes the stranger test with 3 people
- No obvious trademark conflicts
- Social handles available or acceptable alternatives exist
- .com available, or you're intentionally going with another TLD
- Not confusingly similar to a direct competitor
- No unfortunate meanings in major languages
- Domain has clean history (no spam flags)
What If Nothing Good Is Available?
This is the most common frustration. Here's the priority order for solving it:
- Try a different name. Hundreds of great names are still unregistered. Don't anchor on one option.
- Try a different TLD. Many strong startups use .io, .app, or .co. Vercel.com, Linear.app, Loom.com all work fine.
- Add a small modifier. A prefix like "get", "use", or "try" buys time (GetDropbox was Dropbox's early URL). Plan to upgrade later.
- Buy the .com. If the domain is parked and the owner is reachable, make an offer. Premium .coms go for $2k–$50k for most startup names — expensive but sometimes worth it.
Let AI Do the Heavy Lifting
Domain-ate asks smart questions about your business, then generates names that actually fit — checking availability in real time.
Try Domain-ate FreeThe Bottom Line
A great domain name is short, pronounceable, and memorable. It passes the radio test and doesn't create legal risk. It gives you room to grow.
The best founders spend a focused afternoon on this — not weeks — using a systematic process instead of hoping inspiration strikes. Use the framework above, generate volume, filter ruthlessly, and move on.
Your domain name matters, but your product matters more. Don't let perfect be the enemy of shipped.
