Most surf schools spend too much time posting "available slots" and not enough time actually talking to their community. If your feed is just a series of flyers and sunset photos with no comments, you're missing out on the primary signal that tells social algorithms to show your content to more locals and tourists.
The goal isn't just to get a "Like." It's to stop the scroll and get a prospective student to type a response. This builds 'digital rapport' so that when they finally decide to book a lesson, your school is the only one that feels familiar. You want to move away from generic "Who wants to surf?" questions and toward specific prompts that tap into a surfer's ego, their fears, or their favorite gear.
What actually works: Use "This or That" questions. They require zero brainpower for the user to answer, which is exactly what people want when they are scrolling on their lunch break. the lower the barrier to entry, the higher the comment count.
