How do you test ad pieces without wasting the budget?
You run two photos of the same dish, with the same text, for a few days and with the spend split. You keep the one that brings more booking messages and switch the other off. Choose two real photos of the same dish, not of two different dishes. Five pieces are tested at once and none of them gets to say anything. The piece that stays and the one that is switched off, with the messages from each.
