Keeping a restaurant listing accurate: hours, menu link, phone
Hours first. Hungry customers check hours more than anything else. Update them for holidays and seasonal changes.
Link the menu, not the home page. A menu that's one tap away keeps people from giving up.
A phone that's answered. If the restaurant phone rings out during service, say how best to reach you, such as an online ordering page.
Say how people can order. Dine-in, takeout, delivery, reservations: list what you offer.
