AI Attribution Wars: Why 54% of Publishers Still Don’t Trust the Tracking

The affiliate industry has always promised transparency: real results, real payments, real performance. But that promise is under pressure in a world shaped by zero-click search, AI-generated overviews, and vanishing cookies.

And according to the 2025 PMA Industry Study, publishers have noticed. Only 2% of affiliate publishers say they’re “very confident” in the accuracy of tracking through networks and platforms. Just over half feel “somewhat confident.” That means nearly half the industry doubts whether the affiliate channel is properly crediting their contribution.

At a time when affiliate is driving $113B in e-commerce sales and growing twice as fast as the broader e-commerce market, this trust gap isn’t just inconvenient. It’s a critical threat.

So how did we get here? And more importantly, what role will AI play in fixing it, or making it worse?

The Great Trust Gap in Affiliate

The affiliate industry has long relied on traditional last-click attribution models. For most of the channel’s history, that made sense. Track the final interaction, pay the partner. Simple. But simplicity came at a cost: it masked the impact of upper-funnel content creators, social partners, and review sites that planted the seeds but didn’t close the deal.

Now, with third-party cookies disappearing and AI Overviews stealing the first (and sometimes only) click, even that last interaction is under siege.

The result? A growing disconnect between publisher effort and advertiser recognition. And with privacy regulations tightening and traffic sources shifting, many publishers are being left in the dark, literally and financially.

AI Is Changing the Nature of the Click

AI doesn’t just disrupt how users discover products; it redefines the user journey. Platforms like Google Gemini generate answer cards that eliminate the need to click through to affiliate content. AI-curated buying guides may cite products, not publishers. In some cases, affiliate links never get seen, let alone clicked.

That’s a profound problem for an industry built on click-based attribution.

But the irony is: AI can also help solve the attribution problem it helped create.

From Clicks to Signals: AI’s Role in Modern Attribution

Modern attribution modeling is no longer about single actions. It's about patterns. Time on page, scroll depth, repeat visits, partial engagement, signals that hint at influence, not just conversion. The tools to detect these signals already exist, but the key is making them usable and trustworthy across networks.

This is where AI comes in.

• Predictive attribution models powered by machine learning can estimate complex conversion paths, even when user data is fragmented.

  
  

• Attention metrics can track real engagement, helping distinguish between brand lift and bounce.

  
  

• Probabilistic models can assign value to impression-based placements where direct tracking fails.

AI gives us the ability to reward influence, not just outcomes. But only if brands and networks are willing to adopt models that go beyond the last click.

Why This Matters Now: Zero-Click Is Just the Beginning

What we're witnessing is the first wave of attribution disruption. AI-generated summaries, platform-native shopping experiences, and voice-based search are eliminating traditional affiliate pathways. The click is becoming optional, or obsolete.

As this unfolds, the affiliate industry must decide: double down on old models, or lean into smarter, AI-assisted attribution frameworks that reflect reality.

And for advertisers, that means investing in:

• Better first-party data capture.

  
  

• Multi-touch attribution strategies.

  
  

• Transparent communication with partners about how value is measured.

Publishers are ready to evolve, but only if they believe they'll be rewarded for their influence, not penalized for missing the last click.

AIM’s Perspective: Rethinking Measurement, Rebuilding Trust

• Cross-channel insights that bridge affiliate, influencer, and media impact.

  
  

• Transparent attribution methodologies that clients and partners understand.
