Key Performance Indicators to Track for Evaluating Marketing Manager Campaigns on App User Acquisition and Retention
In measuring the effectiveness of marketing managers’ campaigns specifically geared towards app user acquisition and retention, it’s crucial to focus on the most relevant Key Performance Indicators (KPIs) that accurately reflect campaign impact on both attracting new users and maintaining their engagement over time. Properly selected and tracked KPIs empower data-driven decisions to optimize growth strategies and user value.
1. User Acquisition KPIs: Measuring New User Growth and Cost Efficiency

- How to track: Define critical activation events in analytics dashboards and calculate (Activated users ÷ New installs) × 100.
2.2 Time to Activation
Measures the average time elapsed between installation and user activation.
- Why it matters: Faster activation correlates with higher lifetime value.
- How to track: Analyze user event timestamps in tools like Firebase or Amplitude.
3. User Retention KPIs: Understanding Sustained User Engagement
Retention metrics evaluate whether campaigns successfully maintain user interest and habitual app usage over time.
3.1 Retention Rate (Day 1, Day 7, Day 30)
The percentage of users engaging with the app on subsequent days post-install.
- Why it matters: Indicates the stickiness and ongoing relevance of the app experience.
- How to calculate: (Users active on day X ÷ Users at install) × 100.

Conclusion: Build a Comprehensive KPI Framework for Marketing Campaign Evaluation
Effectively evaluating a marketing manager’s campaigns on app user acquisition and retention requires a holistic KPI approach that spans acquisition, activation, retention, engagement, monetization, and user satisfaction metrics.
Best Practices for Tracking KPIs:
- Establish baseline KPIs (e.g., DAU, retention, CPA) pre-campaign.
- Monitor acquisition indicators (new users, CPA, CTR) in real-time.
- Analyze retention cohorts and activation rates post-campaign.
- Tie revenue KPIs (LTV, ARPU) back to acquisition sources.
- Incorporate qualitative user feedback with tools like Zigpoll for continuous improvement.
By aligning these KPIs with business objectives and utilizing advanced analytics and feedback tools, organizations can reliably measure marketing effectiveness, optimize budget allocation, and drive sustainable app growth and user loyalty.
