# Bidding change review reminders
Alerts: Bid change reviews at four different levels
Adalysis tracks the last date a bid or bidding strategy changed. The system can then send you regular reminders to review their impact and ensure they improve performance. This includes:
* Campaign bidding strategy changes
* Ad group-level max CPC, target CPA or target ROAS changes
* Keyword-level max CPC changes (in manual CPC campaigns)
* Product group max CPC changes (in manual CPC campaigns)
Once there's enough data for statistically significant conclusions, you'll see an alert on your **Audit alerts** screen.
Click on it for a before-and-after performance comparison. You can then decide whether keep the changes or revert to a previous bid or bidding strategy.
{% hint style="warning" %}
**Please consider** that performance changes, whether positive or negative, could also have been influenced by other changes during the same time period, e.g. new ad copy or campaign targeting changes.
{% endhint %}
### Customizing your review reminders
You can customize your reminders under **Audit** > **Audit settings** > **Prebuilt** > **Bid reviews**.
1. Choose a **time frame** for the review.
2. Change the **minimum thresholds** for triggering the reminder.
3. **View current results** before considering changes.
