# Ad groups with one ad

Adalysis will alert you to any ad groups that only have one active ad. This is because it can't be included in automatic daily testing. An ad test needs at least two active ads to compare performance.

You'll see the alert on your **Audit** **alerts** screen. Click it for a list**.**

You can create ads for [multiple ad groups at once](/manage/ads/rsas/a-b-testing-of-rsas-in-a-set-of-ad-groups.md). Simply select your ad groups and choose an option from the **Tools** > **Create ads** menu.

Alternatively, click an individual ad group name and create a single ad.
