Time to ROI

Short-term (< 3 months)

I used to obsess over marketing attribution. Every click, every touchpoint, every microscopic interaction had to be tracked and assigned to the "right" channel. My clients demanded it. "Show me the ROI of each channel," they'd say. "Which Facebook ad brought this customer?"

So I built elaborate attribution models. Multi-touch attribution, first-click, last-click, time-decay models - you name it, I implemented it. The dashboards looked beautiful. The reports were comprehensive. And they were completely useless for making actual business decisions.

Here's what nobody talks about: attribution is fundamentally broken in 2025. Privacy regulations killed third-party cookies. iOS updates destroyed Facebook's tracking. And even when tracking "worked," it was telling us fairy tales about linear customer journeys that don't exist.

After working with dozens of SaaS startups and ecommerce stores, I've learned that the companies winning at growth aren't the ones with perfect attribution - they're the ones who focus on distribution over measurement.

In this playbook, you'll discover:

  • Why traditional attribution models are misleading your marketing decisions

  • The dark funnel reality that most attribution systems miss

  • A practical framework for measuring what actually matters

  • How to optimize marketing spend without perfect attribution data

  • Real examples of companies that grew faster by ignoring attribution


Industry Reality

What every marketer has been told about attribution

Walk into any marketing conference or open any growth blog, and you'll hear the same attribution gospel repeated endlessly:

"You can't manage what you can't measure." Every marketer has heard this. The conventional wisdom says you need to track every touchpoint, build sophisticated attribution models, and assign revenue to specific channels with mathematical precision.

The standard recommendations include:

  • Multi-touch attribution models that credit multiple touchpoints along the customer journey

  • Marketing mix modeling to understand channel effectiveness at a macro level

  • First-party data collection to replace third-party cookies and maintain tracking accuracy

  • UTM parameter hygiene to ensure proper campaign tracking across all channels

  • Customer journey mapping to identify all potential touchpoints and optimize them


This advice exists because it feels logical and scientific. Marketing has physics envy - we want our discipline to be as measurable as engineering. Attribution models promise to turn marketing into a precise science where you can optimize inputs to achieve predictable outputs.

The problem? This approach fundamentally misunderstands how customers actually discover and buy from businesses. Real customer journeys aren't linear paths with trackable touchpoints. They're messy, multi-device, multi-channel experiences that span weeks or months, often involving offline conversations, dark social sharing, and subconscious brand building that no attribution model can capture.

Most attribution systems are measuring the wrong things while giving marketers false confidence in their optimization decisions.

Who am I

Consider me as your business complice.

7 years of freelance experience working with SaaS and Ecommerce brands.

My wake-up call came from an ecommerce client who was drowning in attribution complexity. They sold fashion accessories through multiple channels: Facebook ads, Google ads, email marketing, influencer partnerships, and organic social.

The team was obsessed with attribution. They had implemented Google Analytics Enhanced Ecommerce, Facebook's Conversions API, server-side tracking, and even hired a data analyst to build custom attribution models. Their monthly reports looked like PhD dissertations.

But here's what was actually happening: their Facebook ROAS jumped from 2.5 to 8-9 within a month of launching our SEO strategy. Obviously, Facebook didn't magically become 3x more effective. What happened was classic attribution lying - SEO was driving significant traffic and conversions, but Facebook's attribution model was claiming credit for organic wins.

The client's typical customer journey looked nothing like what their attribution showed:

  • Someone would Google search for their problem

  • Browse products on the website

  • Get retargeted with Facebook ads

  • Research reviews on third-party sites

  • Return through email marketing

  • Complete purchase


But the attribution model would show: "Facebook ad drove the conversion." The dark funnel - all those unmeasurable touchpoints - was completely invisible.

I realized we were optimizing for attribution accuracy instead of business growth. The client was making budget allocation decisions based on fictional data while the real growth drivers remained hidden.

My experiments

Here's my playbook

What I ended up doing and the results.

Instead of fighting the attribution dragon, I developed a framework that embraces the dark funnel reality. Here's exactly how I approach marketing measurement now:

Step 1: Accept Attribution is Directional, Not Precise

I stopped promising clients perfect attribution data. Instead, I position attribution as directional intelligence - useful for spotting trends, not making precise ROI calculations. This mindset shift alone improves decision-making quality.

Step 2: Focus on Incrementality Testing

Rather than relying on attribution models, I run incrementality tests. For Facebook ads, we'll pause campaigns for 2-4 weeks and measure the impact on overall conversions. If conversions drop significantly, we know Facebook is driving incremental value. If they don't, we know the attribution was lying.

Step 3: Track Leading Indicators by Channel

Each channel gets measured on its logical contribution:

  • SEO: Organic traffic growth, keyword rankings, search visibility

  • Paid ads: Reach, click-through rates, cost per click trends

  • Email: List growth, engagement rates, deliverability

  • Content: Brand search volume, social mentions, traffic quality


Step 4: Implement Portfolio Theory for Marketing

Instead of optimizing individual channels, I optimize the marketing portfolio. Some channels (like brand awareness) drive unmeasurable value that enables other channels (like retargeting) to perform better. You can't optimize them in isolation.

Step 5: Use Blended Metrics for Decision Making

I track overall business metrics - total revenue, customer acquisition cost, lifetime value - and correlate them with marketing activities over time. This gives a more accurate picture than channel-specific attribution.

The key insight: Stop trying to control and measure everything. Start building systems that work even when you can't track their exact contribution.

Key Insight

Attribution is directional intelligence, not precise measurement. Use it to spot trends, not calculate exact ROI.

Incrementality Over Attribution

Run pause tests to measure true incremental value rather than relying on attribution models to tell you what's working.

Portfolio Optimization

Optimize your entire marketing mix, not individual channels. Some channels enable others to perform better.

Leading Indicators

Track channel-specific metrics that indicate health rather than forcing revenue attribution on everything.

The results speak for themselves. Clients who adopted this approach saw immediate improvements in marketing effectiveness:

Faster Decision Making: Without waiting for perfect attribution data, teams made quicker optimizations based on leading indicators and incrementality signals.

Better Budget Allocation: Portfolio thinking led to more balanced marketing mixes. Instead of over-investing in "high-attribution" channels, clients invested in brand building and awareness that improved overall performance.

Reduced Analytics Overhead: Teams spent less time building complex tracking systems and more time on creative strategy and channel optimization.

Improved Channel Performance: Counterintuitively, caring less about precise attribution led to better channel performance. When you optimize for the channel's natural strengths rather than forcing attribution, results improve.

Most importantly, teams became more experimental. Without the pressure of proving immediate attribution, they were willing to test newer channels and longer-term strategies that drive sustainable growth.

Learnings

What I've learned and the mistakes I've made.

Sharing so you don't make them.

Here are the five most important lessons I learned about marketing attribution:

1. The Dark Funnel is Bigger Than You Think
Most customer touchpoints are unmeasurable. Word-of-mouth, offline conversations, podcast listening, social media browsing - none of this shows up in attribution models, but it drives significant buying behavior.

2. Attribution Accuracy Decreases Over Time
Privacy regulations, ad blockers, and iOS updates make attribution less accurate each year. Building your marketing strategy on attribution data is building on quicksand.

3. Channel Synergy is Real
Channels don't operate in isolation. Brand awareness campaigns make retargeting more effective. SEO content improves paid ad quality scores. Email marketing increases social media engagement. You can't optimize these relationships with single-channel attribution.

4. Leading Indicators Trump Lagging Indicators
Revenue attribution is a lagging indicator. Leading indicators (traffic quality, engagement rates, brand search volume) give you faster feedback loops for optimization.

5. Incrementality Testing Reveals Truth
The only way to know if a channel truly drives incremental value is to turn it off and measure the impact. This is uncomfortable but necessary for honest marketing measurement.

What I'd Do Differently: I'd implement incrementality testing from day one instead of spending months building attribution models first.

When This Approach Works Best: This framework works for any business with multiple marketing channels and complex customer journeys. It's especially valuable for B2B SaaS and ecommerce businesses where customers research extensively before buying.

How you can adapt this to your Business

My playbook, condensed for your use case.

For your SaaS / Startup

For SaaS startups, focus on these key points:

  • Track trial-to-paid conversion by channel, not just signups

  • Measure engagement quality, not just attribution volume

  • Test incrementality quarterly to validate channel performance

  • Optimize for portfolio growth, not individual channel ROAS

For your Ecommerce store

For ecommerce stores, implement these strategies:

  • Focus on customer lifetime value across the entire marketing mix

  • Track brand search volume as a leading indicator of attribution health

  • Use incrementality tests during seasonal lows to avoid disrupting peak periods

  • Measure repeat purchase rates by acquisition channel
