Draft a concise article that guides small venues in marketing local events across Meetup, AllEvents, and local calendars. Start with a clear thesis on why platform-specific messaging matters, then outline 3 actionable tactics (clarity in event purpose, platform-mitted copy, and RSVP flow optimization) and illustrate each with a brief example drawn from the provided event descriptions. Include one mini-template for a Meetup listing, one for AllEvents, and one calendar-export tip. Conclude with a quick metrics snapshot readers can implement next week to assess impact.
