Experienced students will browse profiles of all available tutors, before calling the one they like the most. Therefore you can attract more new students by creating an inviting tutor profile. Try posting a friendly-looking headshot, adding a variety of interests, listing all of your additional languages, and recording a short profile video that showcases your personality. You can also showcase your teaching style by uploading a short (2-5 minute) lesson video.
It can also be helpful if you send promising students an encouraging message after you speak with them. For example: "I really enjoyed speaking to you today! I hope we speak again soon, as I'd love to talk more about ____."
