Beyond social
Restaurants need a clear home for actions Instagram cannot handle well.
Instagram is useful for showing atmosphere, food, specials, and updates. But it is not always the best place for someone who wants to quickly check your menu, confirm your hours, find your location, reserve a table, or place an order.
A restaurant website gives those actions a clear home. It also gives Google a stronger structure to understand your restaurant, your location, your cuisine, and the services you offer.
For restaurants and cafes, a website should not compete with Instagram or Google Business Profile. It should support them by becoming the place where customers can take the next step without guessing where to tap next.
