@BlakeyBChess I think the main benefit of using lichess as a tool to show your videos is two fold.
1. It creates a familiarity of the software for the group you want to attract. Which is beneficial because then they know you know how to utilize the teaching features.
2. It helps lichess determine who is more likely to help their "cause" and it might get them interested in listing you on their tutor page. (Or if you're on the tutor page already, it might help raise you in the list.)
Other than that I think it's a matter of taste. I teach myself. I offer online lessons but the bulk of my students are basically live and in person. I don't believe having a lot of students makes you a better teacher. I believe being able to focus less gives more of a personalized feel. I lightly advertise in groups or forums but don't expect anything serious online unless they in box me with serious intent.
Have you tried being listed as a tutor on lichess? I believe they go as low as 2000 on the main tutor page, or they might even dip into the classes if they offer good rates.
