Workshops & Webinars for absolute beginners in a small community

Hi! I'm interested to get others perspective on facilitating workshops and webinars on astrology for absolute beginners. I've had moderate success with in person workshops in my local community that is quite small (about 250K population) and just started doing webinars this year, which I think I overdid for my beginning audience that I have attracted so far. I'd like to hear from others (1) how did you launch your workshops or webinars and (2) how/where did you advertize and (3) what was successful and what wasn't in your experience? I'd love to hear any input from other astrologers that are teaching. Thank you!
