Alert name: High volume keywords with a quality score drop
Adalysis will alert you to high-volume keywords with significant quality score drops. By default, this is based on 100+ impressions in the last seven days and a negative quality score trend. However, you can edit these thresholds in Audit > Audit settings > Prebuilt > Keywords.
You'll see the alert on your Audit alerts screen. Click it for a list of affected keywords and quality score data.
The view will switch to the Manage > Keywords screen. Here you can review your expected clickthrough rate, ad relevance, and landing page experience to identify how to improve your results.
For a full history of all quality score components, click the icon in the Quality score history column. This can help you to identify the reasons behind the drop.
