If you don't recognize activity on your advertising account, below are a few things you should review:

1. Review your purchase history and account history. Reviewing your purchase history will give you a detailed breakdown of charges on your account. You can click into each Transaction ID to see which ad the transaction was for and how the amount you spent was calculated.
   
   Reviewing your account history will allow you to see recent activity on your ad account.

2. Check to see if you have a daily budget or a lifetime budget. Each time you create a new ad, you'll select a budget for that ad. You'll be able to choose between a daily budget or a lifetime budget. If you set a daily budget but meant to set a lifetime budget or vice versa, you may be billed differently than expected.

• Daily budget: This is the amount you've indicated you're willing to spend on a specific ad set per day. Each ad set will have a separate budget, so keep this in mind if you have more than one active ad set in your account. Your ads will automatically stop showing once your daily budget for the ad set has been met for that day. Learn how to edit your daily budget.
• Lifetime budget: A lifetime budget lets you set an amount to spend over the lifetime of an ad set. Our system will automatically try to evenly spread the amount you spend across the period of time that you've selected. Learn how to edit your lifetime budget.

Note: If you wanted to spend a specific dollar amount over the lifetime of your ad, double check to make sure you set a lifetime budget, not a daily budget.

3. See if your billing threshold was reached. In the Billing Summary section of your Ads Manager, you can view your billing threshold. If your ad is scheduled to run across multiple months, or if it runs longer than when your billing threshold was met, you may see the remaining balance carry over to your next bill.

4. Check for other spenders on your account. If you aren't the only person with access to your ad account, or to the payment method you're using, it's possible you might see another person's spend on your bill. If you suspect this is the case, go to your ad Account Settings in Ads Manager. In the Ad Account Roles section, you'll be able to see who has access to your account. Contact anyone you know who may have placed an order for ads with your payment method.

If you've checked these things, still see purchases that you don't recognize and believe someone has hacked your ad account, please let us know.
