Link your Google Play account

Linking your Google Ads account to your Google Play account automatically creates a list of all the users who have your app installed. Once the link request is approved by the owner of the Google Play account, remarketing lists will appear automatically in your Shared library. Your list will update in real time as users install and uninstall your app, so you can easily and most efficiently remarket to all the users of your app. Learn more about how to link your Google Play account.

Tag the events in your app for remarketing

For even more powerful remarketing, you can tag specific actions that people do in your app so your app signals to Google Ads as these events happen. Once you've tagged those actions in your app, you can create lists that update as people perform these actions in your app. For example, you can target a list of all users who have been active over the past 7 days. Or, you could target a list of users who have taken an action in your app, but haven't completed it, or taken the next step in your app. Learn more at Tag your app for app engagement campaigns.
