Performance monitors help you track trends and spot significant changes fast. We strongly recommend customizing them for your account and campaigns.

Here are five popular performance monitors, ready for you to adapt for your campaigns:

<details>

<summary><strong>Minimum ROAS targets</strong></summary>

This monitor alerts you if your account drops below your minimum ROAS target. Some teams use multiple alerts of this type for changes in scope, such as monitoring brand and non-brand campaigns separately.
