Adalysis will notify you about product groups that are not converting well and hence should be restructured or excluded or the bid should be changed. 

You will see the alert on your Dashboard under the Product groups category.

By clicking on the alert you will be prompted to view the product groups on the relevant screen where you can take action. 

By default, Adalysis uses the following criteria for defining poorly converting product groups: 150 clicks and 0 conversions in the last 90 days. You can easily override these settings in one of two ways:

1. In the Audit Settings of your Adalysis profile, under New Opportunities Alerts → Product Groups Opportunities

2. In the filter Underperforming product groups (accessible from the Product Groups screen), which you will see once you click on the alert on your Dashboard.

You can always revert back to the original settings using Reset to default button.
