Your budget establishes a monthly charging limit for an individual campaign. The charging limit is the average daily budget that you set, multiplied by the average number of days in a month. While your spend may vary each day, you won’t pay more than your monthly charging limit. Learn more About spending limits.
For Performance Max you should:
- Set an average daily budget of at least 3 times your CPA or cost/conv. for the conversion actions selected for your campaign. You have the flexibility to change your budget at any time.
- Check your account daily to know how your campaigns have performed so far.
- Remember that on days when your ads are likely to get you more traffic, you may spend up to 2 times your average daily budget. Those days are balanced by the days when your spend is below your average daily budget.
