Deep linking

A deep link is a URL that opens an installed app directly to a particular screen or piece of content — a specific product page, an article, or a user's profile — rather than dropping the user on the app's generic home screen and requiring them to navigate manually to where the link was meant to take them.

Deferred deep linking extends this to users who don't yet have the app installed: tapping the link sends them to the app store first, and after installing and opening the app, the original destination is still honored. This depends on matching the post-install session back to the original click, which is typically handled by the same infrastructure that performs install attribution, often through a mobile measurement partner. Deep linking differs from a plain app store link in that it carries a specific destination and context through the install process, rather than just directing the user to the app's listing.

Deep linking matters because it removes friction between an ad, email, or notification and the specific content it promised, which measurably improves conversion compared with dropping every user on the same home screen. The main pitfalls are broken links when app content or navigation structure changes without updating the linking configuration, and links that fail to fall back gracefully to a mobile web page or the correct store listing when the app isn't installed or the platform isn't supported.
