Spotlight Indexing
Making app content searchable through the iOS device-wide Spotlight search using CoreSpotlight or NSUserActivity.
Spotlight Indexing is the process of making your app’s content discoverable through the system-wide Spotlight search on iOS devices. When users swipe down on their home screen and type a query, indexed app content can appear alongside web results, contacts, and system settings. This creates an additional entry point into your app that bypasses the App Store entirely.
Implementation Methods
There are two primary approaches to Spotlight Indexing. CoreSpotlight allows you to index specific content items like articles, products, or recipes with rich metadata including titles, descriptions, thumbnails, and keywords. NSUserActivity indexes content based on user behavior, marking pages or screens the user has visited so they can be found again through search. Both methods support deep linking, sending users directly to the relevant content within your app rather than the app’s main screen.
Benefits for App Discovery and Retention
Spotlight Indexing increases the number of touchpoints where users can rediscover and re-engage with your app. Users who find app content through Spotlight are taken directly to high-value screens, improving session quality and retention. For apps with large content libraries, Spotlight Indexing effectively turns every piece of content into a discoverable entry point. This is especially valuable for content-driven apps like news readers, recipe apps, and e-commerce platforms. Well-indexed content also contributes to Siri Suggestions, where the system proactively recommends your app based on usage patterns and indexed data.
