The radio test for domain names
How to use the radio test to avoid confusing, hard-to-spell startup domain names.
The radio test is simple: if someone hears your domain name out loud, can they spell it correctly without extra explanation?
This matters because names travel through conversation. Founders mention them in calls, podcasts, demos, intros and quick messages. A name that needs constant spelling support creates friction.
What causes failure
Names usually fail the radio test because of unusual spelling, repeated letters, unclear word breaks or sounds that could be written multiple ways.
A name can still be distinctive without being confusing. The strongest brandable domains often sound familiar enough to spell and fresh enough to remember.
- Avoid replacing letters unless the result is obvious
- Be careful with double letters across word joins
- Watch for sounds like c, k, s, x and z
- Say the name quickly and slowly before deciding
A practical founder test
Send the name as a voice note to a friend and ask them to type the domain back. If they get it right, the name is doing useful work.
If they hesitate or ask how to spell it, the name may still work, but you should know that you are accepting a real marketing cost.
