The document discusses the benefits of app indexing and deep linking for mobile apps. It notes that app indexing allows apps to be accessible from search results for individual app screens, benefiting user experience and discoverability. Deep linking is required for app indexing but can also stand alone. The document argues that apps provide a better user experience than mobile web for content-heavy apps where users need live updates, like financial apps. Implementing deep linking and app indexing for a financial app led to increased user engagement and retention as well as search traffic and installs. Coordination is required between development teams to implement app indexing successfully.
