Which campaign objective can advertisers use to increase mobile app installs?

The "App Installs" campaign objective is specifically designed to drive downloads and installations of a mobile application. When you select this objective, Reddit's advertising algorithms optimize ad delivery to users most likely to install your app, and the platform provides specific metrics to track install performance. While "Conversions" could theoretically be used for app installs if configured as a conversion event, "App Installs" is a dedicated, optimized objective for this purpose. "Catalog Sales" is for promoting products from a catalog, typically for e-commerce. "Traffic" aims to drive general website or app engagement, not specifically installs.
