Reviews and testimonials are a big factor so if you already have some clients who enjoy working with you, ask them for feedback and encourage them to post on Google. When I was private practice I met lots of clients just being out socially, so be comfortable talking about what you can do to help folks and have the ability to offer a booking on the spot if they seem interested. Now that I've got a staff of 16 therapists working under me, we do a fair amount of advertising, but I never had to as a solo practitioner. I'm doing a workshop on this very thing on the 27th and could handle a video call in if you'd like to attend: wellness coaching workshop @ Bodyworks DW
