Case Study: Reddit achieves 6.5x more app installs and 50% higher 7-day retention with Branch

Reddit Increases App Installs by 6.5x and Boosts 7-Day Retention by 50% using Branch-Powered Cross Promotions

Reddit, the home of thousands of interest-based communities, wanted to grow its native mobile app audience because app users were more engaged and valuable than mobile web users. After launching the app, Reddit struggled to convert new users and lacked clear attribution for which channels—especially email and web-to-app promotions—were driving installs, making it hard to optimize mobile growth.

Reddit partnered with Branch to implement deferred deep linking across web-to-app xPromos and email (integrated with Amazon SES), preserving click context, enabling personalized onboarding, and consolidating attribution in one dashboard. The result: a 6.5x increase in app installs, Branch-powered campaigns driving >25% of installs, +25% engagement and +50% 7‑day retention for xPromo-driven users, and an App Store rank improvement from the Top 150 to the Top 30.
