How do you avoid audiences that are too broad?

The audience stays with people who are nearby and can come to the shift you are advertising. It is not widened with generic food interests if that pulls in people who will not cross the city. Remove interests until the map is back to the one your bookings come from. The audience says food and the ad is seen at the other end of Madrid. One saved audience with the radius and the age the floor recognises, and the rest switched off.
