When setting goals for an App campaign, an education company should consider the app's maturity, business objectives, and app-specific goals. The app's maturity (e.g., new launch vs. established app) dictates appropriate campaign strategies and key performance indicators (KPIs). Business objectives, such as increasing brand awareness or driving sign-ups, provide the overarching direction for the campaign. App-specific goals, like achieving a certain number of in-app course completions or subscriptions, are granular targets directly tied to the app's functionality and value proposition. Competitor strategies might inform tactics but aren't primary goal-setting factors. Annual revenue is a financial outcome, not a campaign goal itself, though campaign goals contribute to it.
