Optimizing user acquisition and retention is essential to scaling your app’s success. When collaborating with a marketing manager, prioritizing the right Key Performance Indicators (KPIs) aligns efforts and drives data-informed decisions to grow your user base and boost long-term engagement.

This detailed guide highlights the critical KPIs you should focus on together, covering acquisition, activation, engagement, retention, monetization, and growth metrics. Each section includes actionable insights to help you maximize results from your joint marketing and product initiatives.

1. User Acquisition KPIs: Measure How Effectively You Attract New Users

1.1 Customer Acquisition Cost (CAC)

Definition: Average marketing spend to acquire a new user.
Formula: CAC = Total Marketing Spend ÷ Number of New Users Acquired
Why prioritize CAC: Ensures your user acquisition channels are cost-efficient and scalable. When CAC exceeds Customer Lifetime Value (LTV), acquisition strategies must be optimized.
How to optimize CAC with marketing manager:

• Analyze CAC by channel (social, paid search, influencers) to allocate budget effectively.
• Monitor CAC trends to refine ad creatives, targeting, and bids.

1.2 Number of New Users / Downloads

Definition: Count of new installs or first-time active users within a defined period.
Why prioritize: Indicates visibility and appeal of marketing campaigns and app store presence.
How to use: Segment new users by acquisition source to identify highest-converting channels and campaigns.

1.3 Conversion Rate from App Store Visitors to Installers

Definition: Percentage of users who install your app after viewing the app store page.
Formula: Conversion Rate = (App Installs ÷ App Store Page Views) × 100
Why prioritize: Directly measures effectiveness of app store optimization (ASO) – visuals, description, reviews.
How to improve: Collaborate on A/B testing app screenshots, videos, and messaging to increase install conversion.

1.4 Click-Through Rate (CTR) on Ads

Definition: Ratio of users clicking your ads relative to total impressions.
Formula: CTR = (Clicks ÷ Impressions) × 100
Why prioritize: Reflects ad relevance and audience engagement. Higher CTR reduces CAC.
How to optimize: Test various ad formats, creatives, and copy with marketing manager for continuous improvement.

2. User Activation KPIs: Track First-Use Success and Onboarding Efficiency

2.1 Activation Rate

Definition: Percentage of new users completing a key action (signup, tutorial completion, first purchase) within a set timeframe post-install.
Formula: Activation Rate = (Users completing key action ÷ Total new users) × 100
Why prioritize: High activation rates correlate with better retention and revenue potential.
How to improve: Iterate onboarding flows and messaging using marketing campaigns and UX enhancements.

2.2 Time to First Key Action

Definition: Average time it takes new users to complete the predefined activation step.
Why prioritize: A shorter time signals a frictionless onboarding experience, increasing chances of retention.
How to use: Identify bottlenecks and collaborate with marketing on timely push notifications or email nudges.

3. User Engagement KPIs: Gauge User Interaction to Drive Retention

3.1 Daily Active Users (DAU) and Monthly Active Users (MAU) & Stickiness Ratio

Definitions:

• DAU: Unique users engaging daily.
• MAU: Unique users engaging monthly.
• Stickiness Ratio = DAU ÷ MAU
  Why prioritize: Measures app stickiness and frequency of user return. Ratios closer to 1 indicate highly engaged users.
  How to use: Align marketing campaigns and product features to increase DAU and improve user habits.

3.2 Session Length and Frequency

Definitions:

• Session Length: Average session duration.
• Session Frequency: Number of sessions per user over time.
  Why prioritize: Longer, more frequent sessions signal user interest and content value.
  How to improve: Promote engaging features or personalized content via marketing channels.

3.3 Screen Flow and Drop-off Rates

Definition: Tracks user navigation paths and where users abandon processes.
Why prioritize: Identifies UX pain points reducing engagement and retention.

4. User Retention KPIs: Key to Long-Term User Value and Growth

4.1 Retention Rates (Day 1, Day 7, Day 30)

Definition: Percentage of users returning after installation on specific days.
Formula: Retention Rate (Day X) = (Users active on Day X ÷ Total new users on Day 0) × 100
Why prioritize: Day 1 and 7 retention reveal onboarding success; Day 30 retention shows lasting value.
How to improve: Use targeted campaigns like push notifications and email drip programs based on retention insights.

4.2 Churn Rate

Definition: Percentage of users lost over time.
Formula: Churn Rate = (Users lost during period ÷ Users at start of period) × 100
Why prioritize: High churn indicates retention issues impactful to growth.
How to address: Develop win-back or loyalty campaigns informed by churn data segmentation.

5. Monetization KPIs: Align Spending with Revenue Growth
