A radio spot is audio only, which forces discipline. No visuals to carry the message, no text to clarify the offer. The entire ad lives in the listener's imagination, built from voice, music, and sound effects.

Lengths run from ten seconds to a full minute. Most fall between thirty and sixty. The spot must grab attention in the first few seconds, because listeners switch stations easily and ads are often the trigger.

Common radio spot elements

• A hook in the opening seconds
• Clear brand mention early and at the end
• A single, repeatable call to action
• Music or sound design that sets tone

Repetition drives recall. A spot heard ten times on a commuter's morning route can stick far better than a single television exposure. Frequency is the medium's advantage.
