When setting up to promote a mobile app, the first important thing is to ensure that the SDK is properly integrated so that the system can record and optimize in-app events, especially key conversion actions such as installs, registrations or purchases. In addition, it is necessary to clearly set up event values and track LTV metrics to allocate budget appropriately. If you intend to run a high-frequency model or non-standard behavior, you need to prepare multiple backup configurations, periodically change the advertising account and evaluate stability before scaling. At present, systems are increasingly strict with abnormal traffic, so everything needs to be carefully prepared from infrastructure, proxy, tracking to content, to maintain campaign durability.
