Uninstall measurement

By comparing the quality of users acquired from different sources (media sources, campaigns, ad creatives, and geo), you can determine the media sources with the lowest uninstall rates, and reallocate funds to them.

Sending uninstall event postbacks to the ad networks you work with is useful for optimizing user acquisition campaigns. You can send the uninstall event by mapping af_uninstall to your ad network. Once the mapping is complete, an event is sent each time a user is identified as having uninstalled the app. Ad networks can use this information to determine which users are less engaged and focus on getting more engaged users. 

In some cases, to comply with regulations like GDPR and CCPA, you might need to exclude users that uninstalled your app from retargeting campaigns. Uninstall information allows you to create exclusion lists and apply privacy measures to protect your customers’ privacy and data.

Methods to exclude users include the following:

• Raw-data reports: A manual method in which you retrieve a list of uninstalled users from the Uninstalls report and create an exclusion list.
• AppsFlyer Audiences: An automatic method in which you define a target audience based on specific criteria (for example, users who haven't uninstalled your app). Users that don't meet the criteria are excluded from the audience.
