Starting on 4 October 2017, campaigns will be able to spend up to twice the average daily budget to help you reach your advertising goals, like clicks and conversions.
On days with lots of high quality traffic, your costs could be up to 2 times your daily budget. This spending is balanced by days when your spend is below your daily budget.
Keep in mind, you won’t be charged more than your monthly charging limit: the average number of days in a month (30.4) multiplied by your average daily budget.
The normal event of accruing more costs in one day than the amount of your average daily budget. However, AdWords prevents your campaign from overspending for the month as a whole.
- Over-delivery can help make up for days when traffic is slow and your ads don't get as much exposure. Here's how: to make sure that you don't miss showing your ads on a popular day, Google might use more of your budget on some days and less on other days. When this happens, your total daily cost could be up to 2 times your average daily budget.
- However, our system makes sure that after an entire month of service, you're never charged more than your monthly charging limit -- the average number of days in a month (30.4) multiplied by your average daily budget.
- If Google overdelivers your ads too much, and you accrue more costs in a complete monthly billing period than your budget allows, a credit might be applied automatically to your account.
- Note that for campaigns that are paused in the middle of the month or that otherwise don't run for the full month, you may see discrepancies between your average daily budgets and your total charges.
