# FAQ ### Why does Appier need all traffic data? Appier needs all traffic data for these products: * AiBid: To do a blacklist, we can find out active users and do not target them. Secondly, we can find out potential users who will install the app by analyzing current users' characteristics. * App re-engagement (including Aictivate): We use the data to find out who possibly engages the app again and show the personalized Ads. ### What is Deeplink? It's a link or path to take users to a specific content directly in your app without redirecting to Google Play or the App Store. It'll enhance user experience as well as a key component for us to take users to the corresponding page when clicking our Ads. Therefore, it's quite important, especially for App engagement campaigns. Here are some official development documents for your reference to implement deeplink. * [Android](https://developer.android.com/training/app-links/deep-linking) * [iOS](https://developer.apple.com/documentation/xcode/allowing_apps_and_websites_to_link_to_your_content/defining_a_custom_url_scheme_for_your_app) ### What’s Deeplink Match/Deeplink Attribution? MMP SDK utilizes deep link parameters to attribute the deeplink to any in-app event. Deeplink Match/Deeplink Attribution is the attribution method usually used in re-engagement campaigns. ### Why Deep Linking is Essential for Mobile Growth? **Doubling Click-to-Open Rates with Seamless Experiences** According to Branch, the primary value of deep linking lies in its ability to create a truly seamless user journey. By directing users straight to specific in-app content rather than a generic home screen, brands can effectively double their click-to-open rates. This frictionless transition ensures that marketing momentum isn't lost, significantly reducing user drop-off. **Driving 2.5x Higher Conversion and 148% Revenue Lift** According to AppsFlyer, the impact of deep linking on a brand's bottom line is even more dramatic. Their data show that users convert at a 2.5x higher rate when they arrive via a deep link than via a regular attribution link. Furthermore, because these links capture higher user intent, they provide a massive 148% lift in Average Revenue Per User (ARPU). This makes deep linking a critical driver for both immediate transactions and long-term profitability. **Shortening the Funnel for Higher Conversions** As Adjust highlights, deep linking serves as a powerful "shortcut" within the mobile ecosystem. By bypassing the mobile web and landing users exactly where they need to be—whether it’s a specific product page or a checkout screen—brands can drastically boost their conversion rates. This streamlined path to purchase is essential for converting user intent into action before the interest fades. **Source** * * * ## How to implement the deeplink mechanism?
