Yes, you can definitely reactivate a paused campaign, especially if it was turned off recently (within 3–7 days). If the campaign had solid performance before being paused, Meta’s algorithm typically picks up close to where it left off—though it may briefly re-enter the Learning Phase.
- If the campaign was paused for a short time (under 7 days), it’s likely to resume with similar performance, though some volatility is possible.
- If it was paused for more than 7–14 days, Meta may treat it like a new campaign and reset learning. Auction dynamics and audience behavior may also have shifted.
- If the campaign didn’t perform well before, reactivating it as-is might not solve the problem—it’s often better to rebuild with improved creative, refined targeting, or new structure.
If you're unsure, turn the old one back on and run it alongside the new one. Let data - not assumptions, decide what to scale or sunset.
