The Privacy Wave
For two decades, affiliate marketing has run on cookies and tracking pixels. The infrastructure assumed we could follow users across the web, attribute conversions accurately, and optimize accordingly.
That assumption is breaking. Privacy regulations, browser changes, and platform policies are dismantling the tracking infrastructure the industry relied on.
The shift isn't temporary. It's structural. Affiliate operators who understand this and adapt will outcompete those who wait it out.
What's Actually Changing
Cookie Deprecation
The biggest change: third-party cookies are being phased out across browsers.
- Safari has blocked third-party cookies by default since 2020
- Firefox blocks third-party cookies by default
- Chrome began deprecation in 2024 and continues rolling out restrictions
- Mobile browsers have largely blocked third-party cookies for years
The implication: less accurate conversion attribution, harder retargeting, weaker cross-site user tracking.
Privacy Regulations
Regulatory pressure is mounting globally:
- GDPR in Europe requires explicit consent for tracking
- CCPA in California gives users rights over their data
- State-level laws in the US are multiplying
- International regulations are getting stricter
The implication: more compliance overhead, higher risk of violations, stricter rules about what data can be collected.
Platform Changes
Major platforms are restricting tracking:
- Apple's App Tracking Transparency requires opt-in for cross-app tracking
- iOS Mail Privacy Protection obscures email open tracking
- Chrome's Privacy Sandbox replaces some tracking with privacy-preserving alternatives
- Email platforms are tightening what they share with senders
The implication: less reliable data across the stack.
AI and User Behavior
AI is changing how users interact with content:
- AI assistants summarize content without visiting sites
- Direct answers reduce clicks that would have been tracked
- Privacy-conscious users increasingly block tracking by default
The implication: even where tracking is technically possible, user behavior is changing.
What This Means for Affiliate Operators
Attribution Is Getting Harder
The reliable attribution affiliate marketers relied on is degrading:
- Last-click attribution undercounts campaigns that initiate but don't close
- Multi-touch attribution requires data that's harder to collect
- Cross-device attribution is essentially broken without login-based tracking
The result: it's harder to know which marketing activities are actually driving conversions. This is uncomfortable for operators used to precise measurement.
Retargeting Is Diminished
Retargeting — showing ads to users who visited your site — relied on cross-site tracking. With privacy changes:
- Cookie-based retargeting is less reliable
- Custom audiences from site visitors are harder to build
- Lookalike audiences based on tracked behavior are weaker
The result: retargeting is becoming a less effective channel. Operators who relied on it need alternatives.
Conversion Data Is Less Complete
Affiliate networks and programs are also affected:
- Some conversions no longer attribute to the referring affiliate
- Cross-device conversions are missed more often
- Tracking discrepancies between networks and merchants increase
The result: affiliate revenue reports show more variance and less certainty than they used to.
What Operators Are Doing About It
Embrace First-Party Data
The most important adaptation: build first-party data relationships.
Email lists: Subscribers who voluntarily provide email addresses are the most durable audience asset. They're not affected by cookie deprecation.
Account-based relationships: Users who log in or create accounts are trackable across devices. Building logged-in experiences preserves some attribution.
Direct community: Discord, Slack, private forums — places where users voluntarily identify themselves create durable audience relationships.
We invest heavily in first-party data because it's the only data we fully control.
Diversify Attribution Methods
Don't rely on any single attribution method:
- Use multiple networks and compare attribution reports
- Use UTM parameters plus network tracking for cross-verification
- Track branded search volume as a proxy for direct conversions
- Survey customers about how they found you
- Monitor direct traffic patterns for clues
Operators who triangulate from multiple sources have a clearer picture than those relying on a single source.
Shift Up the Funnel
When attribution gets harder, focus on activities that don't require perfect attribution:
- Brand awareness that produces direct traffic later
- Content quality that drives organic search and shares
- Email marketing to existing lists with clear attribution
- Partnerships with measurable direct outcomes
These activities produce revenue without requiring sophisticated attribution to justify.
Invest in Conversion Rate Optimization
When attribution is harder, conversion rate matters more. Every visitor who converts is more valuable when you can't track and retarget the others:
- Better product recommendations
- Improved site speed
- More specific calls-to-action
- Better email capture
- More effective comparison content
We invest in conversion optimization as a hedge against attribution uncertainty.
Build Owned Audiences
The most defensive strategy against privacy changes:
- Email newsletters that bring users back directly
- Podcast audiences that don't require cookies to track
- YouTube subscribers who opt in to notifications
- Community members in private spaces
Owned audiences survive any privacy change because they're built on consent and direct relationship, not third-party tracking.
What the Affiliate Networks Are Doing
The major networks are adapting too:
- CJ, Impact, Awin are implementing server-side tracking
- Some are using first-party cookies with user consent
- Others are exploring conversion APIs for direct server-to-server communication
- Several are testing postback URLs for more reliable attribution
Operators should engage with their networks on these options. The networks need operator participation to validate their solutions.
We're actively testing server-side tracking and conversion APIs with our networks. The early results are promising.
The Compliance Imperative
Privacy changes come with compliance requirements:
- Cookie consent banners with explicit opt-in
- Privacy policies that disclose data practices
- User data access requests that need response workflows
- Data deletion requests that need technical infrastructure
These aren't optional. The sites that don't comply face fines, lawsuits, and platform restrictions.
We treat compliance as a non-negotiable investment. The cost of getting it wrong far exceeds the cost of doing it right.
The 2-3 Year Outlook
What we expect in the near term:
- More browsers will block third-party cookies
- More regulations will require consent and disclosure
- Attribution will get harder before it gets easier
- First-party data will become more valuable as third-party data erodes
- AI-driven attribution may emerge as a solution but with its own concerns
Operators who invest in first-party data now will be positioned well for whatever comes next.
The Operators Who Will Win
The operators who thrive in this environment will:
- Build owned audiences as the foundation of their business
- Embrace first-party data and the consent relationship it requires
- Diversify traffic sources to reduce dependency on any single platform
- Optimize for conversion rather than just acquisition
- Invest in compliance as a competitive advantage
The operators who struggle will:
- Wait for the privacy changes to reverse (they won't)
- Rely on the same tracking that's becoming less reliable
- Depend on a single traffic source they don't control
- Treat compliance as overhead rather than infrastructure
The affiliate industry is going through its biggest transition since the rise of mobile. The operators who adapt will outcompete those who don't.
We've made these adaptations across our network. The sites with strong email lists and owned audiences are the most resilient. The ones still depending entirely on third-party tracking are feeling the pressure.
The transition is real. The opportunity is real. The window to adapt is now.
