# Asset group alerts Adalysis will alert you on a weekly basis if an asset group in your Performance Max campaign: * Has poor ad strength\ This means you can replace and test new assets. * Doesn't use audience signals\ Missing signals can cause wasted spend on unwanted search terms and placements. * Doesn't have the number of assets Google recommends\ Missing assets limit the ability of your PMax campaigns to find high-quality asset combinations that convert well. You'll see the alerts on your **Audit** **alerts** screen. Click on them for more details.
