A client in the finance industry wants to use mobile deep links to direct traffic to its app and is measuring against return on ad spend (ROAS) and cost per acquisition (CPA) benchmarks. Which campaign objective should the media planner recommend?

The Conversions objective is correct because it's specifically designed to drive actions like app installs, sign-ups, or purchases, which directly align with a client's goals of optimizing for ROAS and CPA. These metrics are inherently tied to conversion events. Consideration focuses on driving engagement and traffic, not necessarily direct conversions, making it less suitable for ROAS/CPA goals. Awareness aims to maximize reach and brand visibility, which doesn't directly translate to measurable ROAS or CPA. Catalog sales is for e-commerce businesses with product catalogs, which doesn't fit a finance industry client focused on app-based actions.
