## 5 things you didn’t know about deep links
In his presentation, Vitaliy will show how you can use deep links to create an excellent on boarding experience, how to get more organic installs with app indexing and referral campaigns, how to authenticate users with no authentication and more.
In the second part, we will talk about the inconsistency in the deep links implementation on Android and iOS, technical limitations of App Links, Universal Links, custom schemas and what are the missing parts of the deep linking ecosystem that you will have to build on your own. Do not expect step by step implementation guide, this part contains learnings you can not find in the documentation from 4 years of experience in building deep linking infrastructure at GetSocial.
## Mobile Growth Stack: Retention
Ostap Andrusiv states on the fact that average mobile app loses >70% of its users in 3 days. Within 30 days >90% of users are lost. Are you below or above the benchmark? What's your D1/D3/D7/D30 retention?
This talk will focus on retention metric, why you should track it and how can you track it. We'll see how retention influences acquisition, monetization and LTV through a series of industry-backed examples. At the end, we'll have a look at some of the techniques which app developers use to boost retention and fix that leaky bucket.
