Which of the following events does App Event Optimization (AEO) specifically target?

App Event Optimization (AEO) focuses specifically on driving valuable actions that users take within an app, such as in-app purchases and subscriptions. This optimization technique uses data from users who have completed these specific events to find and target similar potential users who are more likely to engage in those behaviors.

The rationale behind targeting in-app purchases and subscriptions is that these actions often indicate a higher level of engagement and intent compared to other actions, such as ad clicks or impressions. By optimizing for these events, advertisers can improve their return on investment by attracting users that are likely to contribute revenue through spending within the app.

The other options, such as user sign-ups, ad clicks, and social media shares, while valuable, do not directly correlate with the primary focus of App Event Optimization. AEO is so nuanced that it centers specifically on purchase-related events which are critical in monetizing apps effectively.
