When you create a page you pick a type, and that choice sets what the page can do. You can’t convert a page from one type to the other later, so it’s worth getting right up front.
General Page
An always-on destination — a program hub, a brand page, a role roundup. Its main button is Follow, and people who follow it get your announcements.
Event Page
A page for something happening at a specific time. It adds a date, a check-in window, a venue or join link, and optional capacity — and its main button becomes RSVP instead of Follow.
Which to choose
If there’s a date and you care who showed up, use an Event Page. If you want an audience you can message over time, use a General Page. Many teams run both and link them together.
