What is the AARRR model?

Definition and origins

The AARRR model, also known as the AARRR funnel, AARRR framework, or AARRR marketing model, is a structured method for analysing each stage of the customer lifecycle. Developed in 2007 by Dave McClure, investor and founder of 500 Startups, the model helps businesses steer their growth strategy using clear, actionable indicators.

The AARRR framework breaks the conversion funnel into five key stages, also called pirate metrics:

• Acquisition: attract new users through targeted marketing channels.
• Activation: generate a satisfying first interaction with the product.
• Retention: encourage users to return and stay engaged.
• Referral: incentivise sharing or recommending the product.
• Revenue: convert usage into revenue via subscriptions, purchases, or upsells.

This marketing funnel applies equally to startups, SaaS products, e-commerce sites, mobile apps, and marketplaces. It aligns with growth hacking logic and KPI-driven management, relying on tools like dashboards, CRMs, and performance indicators.

Objectives and purpose of the AARRR framework

The primary objective of the AARRR methodology is to provide a holistic view of user behaviour, identifying friction points and growth opportunities at each stage of the funnel.

Unlike a purely linear model, this framework encourages continuous data analysis to adapt strategy in real time and improve performance.

Why use the AARRR model in your marketing strategy?

✅ Optimise user experience: refine onboarding, navigation, and key interactions.

✅ Improve marketing KPIs: track the right indicators at each funnel stage.

✅ Reduce churn and increase customer lifetime value (CLV): boost retention and profitability.

✅ Align marketing, product, and sales: unify teams around a shared performance dashboard.

✅ Support your business model: identify the right growth levers to maximise ROI.

Why the AARRR model is essential in digital marketing

The AARRR model is now a cornerstone of digital marketing. It gives businesses a clear, measurable way to structure their strategy around the customer journey.

It's particularly useful for:

🚀 Startups: rapidly test a business model and identify the most effective acquisition channels.

🛒 E-commerce: refine the conversion funnel and optimise the value proposition.

📱 Mobile apps: improve onboarding and engagement through automated user tracking.

💻 SaaS: reduce churn, improve customer retention, and grow lifetime value.

🎯 B2B companies: better understand their personas, automate follow-ups, and build a data-driven marketing strategy.

👉 By applying the AARRR model to your digital marketing strategy, you move from gut feel to data-driven management. That's the difference between reactive growth and controlled growth.

What are the stages of the AARRR model?

Each stage of the customer lifecycle corresponds to a strategic objective, supported by specific AARRR KPIs grouped in a marketing dashboard. That's what makes it such a powerful funnel optimisation tool.

Acquisition: attracting users

Acquisition is the entry point of the marketing funnel. It encompasses all the levers for driving users to your site, app, or tool.

Objective: generate qualified traffic at the lowest possible customer acquisition cost (CAC).

Example acquisition strategies:

• SEO: high-value content targeting strategic keywords.
• SEA / paid ads: Google Ads, Meta, LinkedIn campaigns.
• Content marketing: blog posts, whitepapers, videos, infographics.
• Social media: organic strategy + targeted paid promotion.
• Email marketing: automated sequences, nurturing, lead magnets.
• Partnerships: influencer, affiliate, brand or media collaborations.

KPIs to track in your dashboard:

• Unique visitors
• Click-through rate (CTR)
• Cost per lead / CAC
• Conversion rate by channel

💡 Tip: rather than spreading across every channel, focus on those generating the best conversion rates and a qualified audience.

Activation: creating first engagement

Activation is the moment when the user takes a meaningful action: sign-up, add to cart, account creation, etc.

Objective: help users quickly grasp the value proposition of your product.

Examples of activating actions:

• Onboarding UX: interactive tutorials, personalised walkthroughs, smart pop-ups.
• Discovery offers: free trial, demo, first purchase on us.
• Personalisation: automatic recommendations based on preferences.
• Gamification: badges, levels, scoring from the first actions.

Performance indicators (KPIs):

• Sign-up rate after visit
• Onboarding completion rate
• Key actions completed in session 1
• Average time spent on the platform

💡 Growth hack: improve activation by reducing the time it takes to reach the "aha moment" — the moment users truly understand the value of your service.

Retention: bringing users back

Retention is the ability to maintain engagement over time. A strong retention rate signals that your value proposition addresses a recurring need.

Objective: prevent churn and grow lifetime value (LTV).

Retention strategies to test:

• Automated re-engagement emails and useful content
• Targeted push notifications
• Regular product updates, new features, in-app content
• Loyalty programmes with progressive benefits

AARRR KPIs to monitor:

• Retention rate at 7 / 30 / 90 days
• Churn rate (cancellations / unsubscribes)
• Recurring sessions per user
• NPS (if measured post-usage)

💡 Best practice: use a CRM or marketing automation tool to segment your user base and trigger the right messages at the right time.

Referral: creating viral growth

Referral transforms satisfied users into brand advocates. It's a powerful organic growth engine.

Objective: reduce overall CAC and amplify virality.

Examples of viral activation:

• Referral programmes with dual rewards (referrer + referred)
• Easy sharing via WhatsApp, social media, email
• Exclusive offers for power users
• "Ambassador" badges or status tiers

Key KPIs:

• Net Promoter Score (NPS), or referral rate
• Number of referrals per active user
• Share rate
• Viral coefficient: the speed at which customers attract new prospects through word of mouth

💡 Key takeaway: people share what makes them look good or what genuinely helps them. Make your product do both.

Revenue: converting usage into revenue

The final stage of the AARRR framework, monetisation consists of converting active usage into revenue, directly or indirectly.

Objective: maximise average revenue per user (ARPU) and lifetime value (LTV).

Revenue strategy examples:

• Freemium with premium upgrade path
• Monthly or annual subscriptions with time-limited offers
• Upsell and cross-sell to maximise average order value

KPIs to add to your marketing dashboard:

• Conversion rate to paying customer
• Subscription churn rate
• ARPU (Average Revenue Per User)
• LTV (customer lifetime value)

💡 Key insight: strong retention is often the most cost-effective strategy for generating more revenue.

How to apply the AARRR model

The AARRR model should not be treated as a simple sequential checklist. It's a strategic management tool for identifying the most profitable growth levers and concentrating effort where it will have the greatest impact.

The goal isn't to optimise every stage simultaneously, but to spot the bottlenecks in your conversion funnel. Careful data analysis reveals the critical stage that's holding back overall performance — and that's where you focus first.

A targeted, agile, and evolving approach

Every company, product, and target audience has its own dynamics. That's why the AARRR framework should be treated as a modular, adaptive system, adjusted based on:

• the product's maturity stage (launch vs. scale),
• the business model (SaaS, e-commerce, mobile app, marketplace…),
• the target personas,
• and the resources available.

Often, a single underperforming stage is enough to drag down the entire funnel. For example:

• 🎯 Strong traffic but few conversions? → Activation issue: the user experience isn't compelling or the value proposition isn't landing.
• 🛑 Mass sign-ups but inactive users? → Focus on retention — via automated follow-ups, targeted re-engagement, or a more progressive onboarding flow.
• 📉 Users love your service but you're not generating revenue? → Revisit monetisation via pricing tests, upselling, or better segmentation.

Use cases and optimisation strategies

The AARRR model can be applied across sectors and business types. Here are some concrete application examples by domain.

Startups & Growth Hacking
The primary objective is to accelerate growth and identify blockers. Key strategies include testing multiple acquisition channels to find the most effective, optimising onboarding for fast activation, and integrating virality mechanisms to maximise referral. KPIs to track: CAC, activation rate, and retention rate.

E-commerce
The goal is to optimise the purchase funnel and loyalty. Recommended approaches: improve UX with detailed product pages, implement abandoned cart re-engagement, and build a loyalty programme to drive repeat purchases. Relevant KPIs: conversion rate, average order value, and number of repeat orders.

SaaS (Software as a Service)
The main goal is to maximise subscriber acquisition and retention. Strategies include implementing a free trial with effective onboarding, sending personalised emails and notifications to encourage usage, and adapting pricing plans to user needs. KPIs to track: activation rate, churn rate, and LTV.

Mobile apps
The goal is to improve engagement and monetisation. Recommended strategies: optimise UI/UX for a smooth experience, use intelligent push notifications based on user activity, and test different monetisation models (freemium, in-app purchases, ads). KPIs to monitor: 7-day and 30-day retention, sessions per user, and conversion rate to paid.

💡 Key advice: whatever the industry, the AARRR model must be driven by precise data to optimise performance at each funnel stage.

Best practices for applying the AARRR model

To fully leverage the AARRR framework, adopt a structured, data-centric approach with flexibility in execution. This model isn't a magic formula — it's a continuous optimisation framework for the user lifecycle.

1. Collect and analyse the right data
   • Track marketing KPIs specific to each stage: activation rate, retention rate, CAC, LTV, ARPU, etc.
   • Use tools like Google Analytics, Mixpanel, Amplitude, or a solid CRM to centralise data.
   • Identify drop-off points in the conversion funnel and optimisation opportunities.
2. Prioritise the highest-impact actions
   • Focus effort where the growth cost is highest.
   • Build a prioritisation matrix to select high-value initiatives.
   • Work stage by stage: don't try to improve everything at once.
3. Test, adjust, repeat
   • Run A/B tests, targeted experiments, or pilot campaigns.
   • Cross-reference quantitative data with qualitative user feedback.
   • Adapt tactics regularly based on market signals and evolving behaviours.
4. Avoid classic mistakes
   • Don't settle for strong traffic without real activation rate behind it.
   • Avoid monetising too fast: without durable engagement, revenue stays fragile.
   • Don't rely on gut feel: decisions must be data-driven, not intuition-based.

💡 The AARRR model is above all an iterative process. More than a method, it's a continuous learning mindset. The goal isn't to get everything right immediately, but to test, measure, learn, and adjust until you've built a high-performing, sustainable marketing funnel.

A new stage in the model? Awareness

In recent years, a recurring question has emerged in discussions around the AARRR model: should a sixth stage be added before Acquisition, called Awareness?

The idea is simple: before attracting users to a site or app, they need to know the product or service exists. This phase precedes Acquisition and aims to build visibility with a target audience.

Why add an Awareness stage?

In a saturated market, being visible isn't enough — you need to exist in consumers' minds before they take action. That's where Awareness comes in, defined as:

• All actions aimed at building brand recognition before actual user acquisition.
• Long-term work to establish your brand as a reference in your field.

Common Awareness strategies include:

Brand identity and branding strategy: build a strong, distinctive image that leaves a lasting impression. This often goes hand in hand with PR and influencer relations, which build credibility and visibility through trusted opinion leaders.

Brand awareness advertising — via display, YouTube, TV, or out-of-home — aims to quickly capture a broad audience's attention. In parallel, SEO content leverages articles, videos, and guides to rank on Google before users are actively seeking a solution.

Social media and community building allow you to grow an engaged community that naturally amplifies the brand. Finally, strategic partnerships offer the chance to leverage other companies' or events' visibility to strengthen your own presence.

Concrete example: an innovative sneaker brand doesn't just build a website and run Facebook ads. It invests first in branding and inspiring content on TikTok and Instagram to build anticipation before acquisition even begins.

Awareness vs. Acquisition: complement or redundancy?

Some growth marketing experts consider Awareness already embedded in the Acquisition phase, since becoming visible is part of acquisition itself. Others argue these two concepts are clearly distinct:

In Awareness, the primary goal is to build lasting presence in the audience's mind. Expected output: increased brand recognition. This plays out over a medium-to-long-term horizon and is measured through KPIs such as recall rate, social media mentions, or branded Google search volume.

Conversely, Acquisition focuses on generating qualified traffic. Results are concrete and near-term — visitors arriving, leads generated. This has a much shorter time horizon, measured via KPIs like visitor count or conversion rate.

The debate remains open: should these two stages be truly separated, or should Awareness simply be seen as a strategy that fuels Acquisition?

Should you build Awareness into your strategy?

Awareness is especially valuable for:

✅ Innovative products or new categories → You need to create the need before acquiring.

✅ Highly competitive markets → A strong brand differentiates from the very start.

✅ Long decision-cycle products (B2B, premium, tech) → Awareness smooths future conversion.

Conversely, for a product addressing an immediate need (e.g., emergency repair), focus directly on Acquisition.

The AARRR model is an essential tool for optimising growth by identifying friction at each stage of the user journey. Rather than improving everything at once, prioritise the highest-impact actions and adjust strategy based on data.

The key: analyse, test, optimise. Now it's your turn.
