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 spending 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 three 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 two times your average daily budget. Those days are balanced by the days when your spend is below your average daily budget.
