Adalysis includes in a single-adgroup test a maximum of 15 active ads. In general, it is not advisable to have more than 3 or 4 ads in an adgroup, because ad testing will take longer to reach valid results.
An alert will be triggered on your dashboard if we find more than 15 active ads in an adgroup during our daily checks. This is to help you identify which ads to pause.
Clicking on the alert displayed in your dashboard you’ll be able to review the list of adgroups with more than 15 ads. The screen will be pre-loaded with this filter to show the relevant adgroups.
