Does the rest of the movement know your group exists?
If you're a local group, it's really important your group is on the Local Group map and the "pathway" - the way new joiners can find you, get in touch, and get looped into your meetings and actions - is accurate. If you need support setting up a join form and mailing list, read this page.
If you're a community group, make sure you're listed in the Community Group section on this page, with accurate contact info.
