# Keywords with a rising CPA

For manual bidding campaigns, Adalysis will alert you when the cost per conversion (CPA) of your keywords increases despite no recent bid changes. This gives you the chance to analyze the results and pinpoint the reasons.

You'll see the alert on your **Audit alerts** screen. Click it to see a list of affected keywords and CPA metrics.

### Customizing your alert

By default, Adalysis will check for keywords with a CPA increase of over 30%. It compares the last seven days to the last 30 days. Go to **Audit** > **Audit settings** > **Prebuilt** > **Keywords** to change these conditions and set conversion thresholds.

You can also choose whether to track **cost / conversion** or **cost / all conversions**.

{% hint style="success" %}
In your audit settings, you can create an [automatic action](/tools/audit/how-to-auto-resolve-alerts.md) to decrease bids for affected keywords.
{% endhint %}

### Investigating CPA trends

Use the [Performance Analyzer](/tools/performance/root-cause-analysis-with-the-performance-analyzer.md) to see how the rising CPA affects your conversion volume and other important metrics. You can then decide whether to change bids for the affected keywords.

Possible causes of a rising CPA may include:

* Rising CPC — this may be due to decreased quality scores, changes in competition or targeting&#x20;
* Decreasing conversion rate
