The Challenge: Static In-Apps with Limited Impact
Before mid-2025, Testbook relied on static in-app banners for communication. These banners were informative but lacked interactivity, leading to low click-through rates (CTRs), minimal repeat engagement, and low conversion contribution.
The Turning Point: Discovering Gamification Inside WebEngage
Testbook leveraged WebEngage’s flexibility to build custom, gamified in-app experiences with interactive content. The “Answer & Win” quiz enabled users to unlock dynamic rewards based on correct answers, driving engagement and boosting conversions.
Key Innovation:
- 1 correct answer = 10% discount
- 2 correct answers = 11% discount
- 3 correct answers = 12% discount
The Strategy: From Campaigns to Interactive Experiences
Testbook integrated gamified in-apps into every sale strategy, aligning user psychology with cultural relevance and campaign themes. The in-app experiences included various interactive formats:
- Answer & Win: Users unlocked discounts through quiz participation
