— Why do not our ads work?
— Such state just can't occur: advertising does work anyway.
But another topic to discuss is that an almost any nonpro is mistaken to call “advertisement” a simple inscription “SALTED STALKS!” followed by a phone number both typed as catchy as possible on some space rented by “the advertiser”.
It may even be a “very good”, “crowded” space! This is not an advertisement — it's just your sign over someone else's door. Such solutions surely “bring” no more than messages like “sorry, our store just moved away” or “no more positions like this“ sticked to your real offer do.
