What is the AARRR Pirate Metrics Framework?
The AARRR Pirate Metrics Framework is a model of metrics that breaks down the customer journey into five key stages in the acronym: Acquisition, Activation, Retention, Referral, and Revenue. Developed by Silicon Valley investor Dave McClure, this framework is a proven pathway to analyzing and enhancing user behavior. The acronym’s comical resemblance to a pirate’s call is why you might know AARRR as the Pirate Metrics.
Applying the AARRR framework can help track performance effectively, optimize conversions, and ultimately drive sustainable growth. Let’s break down this pirate funnel and explore how it can shape the success of your business.
How does the AARRR Model work?
The AARRR Framework is essentially a marketing funnel– subsequent stages in a customer journey. The pirate funnel narrows down as the number of customers reduces in each phase, from learning about a product or service to making the purchase. The AARRR model covers customer tracking along:
- Acquisition – How your business gets visitors
- Activation – How your visitors become users
- Retention – How users become loyal
- Referral – How users become net promoters
- Revenue – How users become paying customers
Understanding how to measure conversion and engage customers through each step of the AARRR funnel can be your key to maximizing business growth.

The Five Stages of the AARRR Framework
The AARRR funnel consists of five crucial stages representing different aspects of the user journey. Here’s a breakdown of each stage:
1. Acquisition – Attracting Potential Customers
Acquisition is all about how customers find your product or service. Businesses need to identify where their target audience spends time—be it social media, search engines, or referral networks—and craft strategies that effectively draw them in.
Key metrics to track:
- Website traffic
- Click-through rates (CTR)
- Cost per acquisition (CPA)
- Source-specific conversion rates
2. Activation – Creating the First Connection
Once a user lands on your platform, the next goal is customer activation. Getting users to visit your site isn’t enough, they need to experience the core value of your product early on. This could mean signing up for a free trial, completing an onboarding process, or using a key feature for the first time.
Key metrics to track:
- Sign-up rate
- Onboarding completion rate
- Time to first meaningful action
3. Retention – Keeping Users Engaged
Retention is what makes the difference between a one-time user and a loyal customer. This stage brings the focus on keeping users engaged over time. High customer retention means customers find your product valuable and continue using it regularly. Creating experiences that keep users coming back may involve personalized content, notifications, or subscription models.
Key metrics to track:
- Churn rate
- Daily/weekly/monthly active users (DAU, WAU, MAU)
- Repeat purchase behavior
4. Referral – Turning Customers into Advocates
Word-of-mouth marketing can be a powerful driver of growth. When users are delighted by a product, they naturally share it with their network. Encouraging referrals through incentives and seamless sharing features in this stage can lead to exponential growth.
Key metrics to track:
- Net Promoter Score (NPS)
- Number of referrals per user
- Referral conversion rate
5. Revenue – Monetizing Your Efforts
At the end of the day, revenue generation is the ultimate goal. Revenue metrics measure how effectively your business converts users into paying customers. This stage focuses on optimizing pricing strategies, reducing friction in the buying process, and increasing customer lifetime value through subscription models, upsells, or premium offerings.
Key metrics to track:
- Average revenue per user (ARPU)
- Customer lifetime value (CLV)
- Conversion rates from free to paid users
- Revenue growth rate
