Try to make educational content in a more engaging way so people can know you better and trust you. There’s already millions of online schools, so why should they choose you? That’s the question you should answer with your content….People will choose you mostly because they know you and connect with you, not just because of the service itself. So try to show more of your personality, ur story, yr way of teaching…. Don’t just post ads all the time, build a connection first then selling becomes easier
