You can edit some properties of a live campaign without restarting it. From the campaign view, click Edit.
What you can change while running:
- Total budget (raise it freely; lower it as long as the new total is above already-spent).
- Daily cap.
- End date (move forward or back, must be in the future).
- Targeting — adjust region, tier, demographics, category, explicit exclusion.
What you can't change:
- Campaign type. Switching Access ↔ Premium ↔ Research means a new campaign.
- Creative for Access Nasqs. Edit the composition, then save — but a meaningful change goes through admin review before the new version takes over.
- Question set on Premium and Research campaigns once viewers have started responding. Editing the questions mid-campaign invalidates the data; new questions = new campaign.
After targeting edits, the completion forecast recalculates against the remaining budget. You see what the change does before saving.
Changes save the moment you confirm. Serving picks up the new parameters within a few minutes.
If you want significantly different targeting and creative, duplicating the campaign and running a fresh one usually gives you cleaner results data than editing in place.
