Interest is not proof.

A polite reaction is different from a market signal people will act on.

Resonance appears in behavior.

Use sharper hypotheses, buyer language and objection patterns before adding more noise.

Build from evidence.

A stronger niche is not guessed. It is shaped from signals the market keeps giving back.
