If your new campaign has been running for 4 days and it's showing stable performance (consistent conversions, good CTR, reasonable CPA), you can start increasing the budget now—you don’t need to wait a specific number of days as long as the data looks healthy.
Here's how to approach it:
- Day 3 to Day 5 are typically a good time to consider scaling, especially if the campaign has exited or stabilized within the learning phase.
- Start with a 20–30% budget increase to avoid shocking the algorithm.
- If you're using Campaign Budget Optimization (CBO) or Advantage+, the system can often handle even larger increases (up to 50%) without disrupting performance, but monitor results closely.
- After increasing, let it run for another 2–3 days before making more changes.
- Avoid editing anything else when you increase the budget (like creatives, placements, or targeting), or it may restart the learning phase.
