Engagement Campaigns

Engagement Framework

1. Engagement Model Selection:

Duolingo caters primarily to active and engaged users, making the Depth-based engagement framework most relevant. This framework prioritizes the intensity and value experienced within each session rather than just the frequency of use.

Reasoning: While frequency of use isn't unimportant, Duolingo's core value lies in the depth of learning achieved within each session. Users come to improve their language skills, and simply counting logins or lesson attempts doesn't tell the whole story. The Depth-based framework focuses on how users engage with the content and how much value they extract, making it a better fit for Duolingo's goals.

1. Depth as the Primary Driver:

Focusing on frequency alone overlooks the crucial aspect of user immersion and value extraction. While Duolingo tracks attempted lessons, the true measure of engagement lies in the time spent actively learning and comprehending. This emphasizes metrics like:

• Lesson completion time: Indicates thorough engagement with lesson content.
• Story time spent: Reflects active reading and comprehension of cultural context.
• Podcast immersion: Measures dedicated absorption of authentic language usage.
• Exercise duration: Highlights focused practice and skill development.

Reasoning: Simply completing lessons doesn't guarantee effective learning. Time spent actively engaged with the material, like carefully studying grammar points, understanding stories, or absorbing authentic language in the podcast, is a stronger indicator of progress and user satisfaction.

3. Breadth as a Complementary Layer:

While depth offers the core learning experience, breadth encourages exploration and reinforces core lessons through diverse features:

• The Duolingo Podcast: Provides exposure to natural conversations, improving comprehension and enriching the learning experience.
• Language Exchange: Enables contextual conversations with native speakers, boosting speaking confidence and cultural understanding.
• Leaderboards & Streaks: Foster healthy competition and incentivize consistent engagement.
• Stories & Articles: Offer immersive reading practice and cultural insights.

Reasoning: While depth is crucial, offering only one learning style or format can become monotonous and limit user engagement. Breadth encourages exploration of different features like podcasts, stories, language exchange, and leaderboards, which can:

• Reinforce core lessons: Podcasts add real-world context, stories provide cultural insights, and challenges motivate deeper practice.
• Cater to diverse learning styles: Some users prefer gamification, while others enjoy immersive reading. Having options increases engagement for everyone.

4. Applying Depth & Breadth in Features:

• Gamification: Points, badges, and streaks (breadth) incentivize engaging with various lessons (depth).
• Personalized Learning Paths: Tailored based on user performance and interests, ensuring relevant and engaging content (depth & breadth).
• Adaptive Difficulty: Adjusts to challenge skills effectively, increasing immersion and maximizing learning (depth).
• Challenges & Events: Encourage collaboration and exploration of different features (breadth), furthering learning within lessons (depth).

Reasoning: Each feature should contribute to both depth and breadth:

• Gamification: Points, badges, and streaks (breadth) motivate users to engage with diverse lessons and exercises (depth).
• Personalized Learning: Tailored paths based on user performance and interests ensure relevant and engaging content (depth & breadth), catering to individual learning styles.
• Adaptive Difficulty: Dynamically adjusting difficulty challenges users effectively, leading to deeper immersion and maximized learning (depth).
• Challenges & Events: Encourage collaboration and exploration of different features (breadth), also pushing users to actively practice within lessons (depth).

5. Comparison with Competitor Framework:

• Memrise: Primarily frequency-based, focusing on streaks and daily completions. Less emphasis on immersive depth.
• Babbel: Offers structured courses with diverse content but lacks Duolingo's gamification and community features, limiting breadth.

Reasoning: Comparing Duolingo's framework to competitors helps understand its strengths and potential areas for improvement:

• Memrise: Focusing solely on frequency through streaks and daily completions might lead to superficial engagement and less emphasis on deep learning.
• Babbel: Structured courses offer diverse content but lack Duolingo's gamification and community features, potentially limiting user engagement and exploration (breadth).

6. Future Developments:

• AI-powered personalized recommendations: Suggest content based on user progress, interests, and preferred learning styles, further individualizing depth.
• Virtual Reality (VR) integration: Create immersive language learning experiences, enhancing depth and engagement.
• Live instructor sessions: Offer personalized guidance and real-time interaction, strengthening both depth and breadth.

Reasoning: Continuous innovation is crucial for maintaining user engagement. Duolingo can leverage technology to:

• AI-powered recommendations: Personalize content based on individual progress, interests, and learning styles, offering highly relevant and engaging experiences (depth & breadth).
• VR integration: Create immersive language learning experiences like virtual conversations with native speakers, furthering deep engagement and cultural immersion (depth).
• Live instructor sessions: Offer personalized guidance and real-time interaction, providing focused learning support and boosting confidence (depth).

Retention Efforts:

Current Retention Rate: 70%

Retention Curve: Flattens after 3 months

For example: If career-focused learners exhibit the highest retention rate due to their intrinsic motivation for language learning, consider offering more career-oriented content and partnerships with relevant companies. Analyze channels like email marketing and app notifications to see which drive the most return users. If personalized learning plans show high impact on retention, consider promoting and enhancing this feature further.

Best Retention Drivers:

• ICP: Career-Focused Learners
• Channels: Email marketing, app notifications
• Sub-Features: Personalized learning plans, fluency assessments

Churn Reasons:

• Voluntary: Lack of progress, limited content, feature dissatisfaction.
• Involuntary: Technical issues, pricing changes, external factors.

Negative Actions:

For example: If lack of progress is a major voluntary churn reason, analyze learning paths and content difficulty to ensure users feel a sense of achievement and advancement. For involuntary churn due to technical issues, prioritize bug fixes and performance improvements. Monitor NPS score, support ticket volume, and other relevant metrics to identify early signs of user dissatisfaction and address them proactively.
