When planning an app marketing campaign, a company should consider three key factors for effective targeting. First, app-specific goals are crucial, as they define what the campaign aims to achieve within the app itself, such as increasing installs, in-app purchases, or user engagement. Second, business goals provide the broader context, aligning the app campaign with overall company objectives like revenue growth or market share expansion. Finally, the app maturity stage is vital because a newly launched app will have different marketing needs (e.g., awareness) compared to a well-established app (e.g., re-engagement). "Annual revenue" is a financial metric, not a targeting consideration. "Competitor strategy" is important for market analysis but not a direct targeting element for their own campaign.
