Here’s why it matters more than people expect: we bring people to your profile, and what they find there decides whether they follow. An account with fresh, relevant content converts far better than one that’s been quiet for two weeks.
Stories help too, daily if you can manage it. They keep you visible to the followers you already have.
If your account goes quiet for 7 days you’ll get a nudge from us. That’s not nagging, it’s the single biggest lever you control.
