Deep linking routes users directly to a specific screen inside an app from an ad or link, rather than dropping them on the app's home screen.
A deep link is a URL that opens a specific location inside a mobile app rather than the app's home page. Clicking a deep link in an ad for a shoe sale takes you directly to that sale's page inside the app, not to the app's home screen where you'd have to navigate there yourself.
Deferred deep linking extends this capability to users who don't have the app installed yet. When a user without the app clicks a deep link, they're redirected to the App Store or Google Play to install the app. After installation, the deferred deep link fires and routes them to the correct screen inside the app on first open. This creates a seamless experience from ad to in-app destination without any navigation friction.
Deep linking is essential infrastructure for retargeting campaigns, which need to route lapsed users directly to the content or offer relevant to the ad they clicked. It also significantly improves onboarding conversion by landing new users on the most relevant in-app experience instead of a generic home screen.
Every extra navigation step between an ad click and the intended in-app destination costs you conversions. Users who land on the home screen and have to find what they were promised by the ad are far more likely to drop off than users delivered directly to it. For retargeting specifically, deep linking is non-negotiable: if your ad promises a specific offer and the link opens the home screen, the campaign simply won't convert.
Example
“A shopping app runs a retargeting campaign showing users items they viewed but didn't purchase. Each ad deep links directly to that specific product page inside the app. Users who tap the ad land on the exact product, reducing the steps to purchase from 4 to 1.”
Retargeting serves ads to users who have previously interacted with your app or website, re-engaging lapsed users or moving near-converters down the funnel.
