First-party data—information collected directly from your audience with their consent—has emerged as the cornerstone of effective digital marketing in this cookieless era. Unlike borrowed or purchased data, first-party data provides authentic insights into customer behaviour, preferences, and needs.
The shift away from cookies isn’t just a technical challenge—it’s an opportunity to build stronger, more transparent relationships with your audience. This article provides concrete strategies for collecting, managing, and activating first-party data to drive effective advertising in a privacy-first digital ecosystem.
Essential Research for Operations
Understanding the current state of cookieless advertising requires examining how the industry has evolved and what research tells us about effective first-party data strategies.
The Cookie Deprecation Timeline
The phase-out of third-party cookies has been gradual but decisive:
- 2017: Apple’s Safari introduced Intelligent Tracking Prevention
- 2019: Firefox blocked third-party cookies by default
- 2020: Google announced plans to phase out third-party cookies in Chrome
- 2024: Google began testing cookie deprecation with 1% of Chrome users
- 2025: Complete phase-out across most major browsers
According to Adobe’s analysis, this transition has already significantly limited the scope and scale of personalized ads, with brands increasingly relying on first-party data to maintain targeting capabilities.
The Value of First-Party Data
| Data Type | Source | Quality | Privacy Compliance | Longevity |
|---|---|---|---|---|
| First-Party Data | Direct customer interactions | High (directly observed) | High (with proper consent) | Long-term asset |
| Second-Party Data | Trusted partners | Medium-High | Medium (dependent on partner) | Medium-term |
| Third-Party Data | Data aggregators | Variable (often lower) | Low (tracking-dependent) | Diminishing rapidly |
Research from Salesforce Data Cloud research demonstrates that first-party data delivers significantly higher ROI than third-party alternatives, with campaigns based on first-party data showing conversion rates up to 3x higher than those using third-party data.
Reality: While individual first-party datasets may be smaller, their quality and relevance typically deliver higher conversion rates. Additionally, as Relay42, strategies like data clean rooms and privacy-compliant data collaborations are enabling brands to achieve scale without sacrificing privacy.
Regulatory Landscape
The shift toward first-party data isn’t just technical—it’s regulatory. Major privacy regulations worldwide have accelerated the move away from third-party tracking:
- GDPR (EU): Requires explicit consent for data collection
- CCPA/CPRA (California): Gives consumers right to opt out of data sales
- LGPD (Brazil): Establishes data subject rights similar to GDPR
- PIPL (China): Restricts cross-border data transfers
According to Invoca, these regulations require companies to be transparent about how they collect and use data, giving users the right to opt out of data collection—making first-party data with proper consent the safest approach from a compliance perspective.
Valuable Introduction for Businesses
For businesses navigating the cookieless landscape, understanding the strategic value of first-party data is essential for maintaining effective advertising operations.
The Business Case for First-Party Data
The shift to first-party data isn’t just a technical necessity—it’s a business opportunity. Companies that have built robust first-party data strategies are seeing tangible benefits:
- Higher conversion rates: Ads based on first-party data convert at 2-3x the rate of third-party data
- Improved customer experience: More relevant messaging leads to better customer satisfaction
- Reduced ad waste: Better targeting means fewer wasted impressions
- Increased customer lifetime value: Better understanding of customers drives loyalty
- Greater independence: Less reliance on walled gardens and third-party platforms

Actionable Facts for Businesses
To effectively implement first-party data strategies, businesses need concrete facts and actionable insights about the cookieless advertising landscape.
Key Performance Indicators for First-Party Data
When evaluating your first-party data strategy, focus on these critical metrics:
