Building First-Party Data Strategies in a Cookie-Less World

2 Oct

For more than a decade, marketers relied on third-party cookies to track users across the web, personalize ads, and measure campaign performance. But with privacy regulations tightening and browsers phasing out cookies, the digital marketing world has entered a new era—one where first-party data is the most valuable asset a business can own.

In this cookie-less world, companies that build strong first-party data strategies will not only survive but thrive, creating deeper customer relationships and future-proofing their marketing.

Why Cookies Are Disappearing

Google Chrome, following Safari and Firefox, is eliminating third-party cookie tracking. This shift is being driven by:

Privacy Regulations: Laws such as GDPR in Europe and CCPA in California demand stricter consumer data protections.
Consumer Expectations: Customers want transparency, control, and trust in how their data is used.
Industry Trends: Big tech is moving toward privacy-first ecosystems where consent is central.

What worked for advertisers in the 2010s no longer works in 2025. Brands now need to rethink how they collect, store, and activate customer data.

What Is First-Party Data?

First-party data is information a business collects directly from its customers and audience. Unlike third-party data, which comes from external trackers, first-party data is gathered through consent-based interactions. Examples include:

Customer emails collected during sign-ups
Purchase history from e-commerce platforms
Engagement data from apps or loyalty programs
Feedback from surveys and customer service channels
Website browsing behavior on your owned domains

This type of data is more reliable and accurate because it comes directly from your own interactions with customers.

Why First-Party Data Is Now Essential

In a cookie-less world, first-party data isn’t just helpful—it’s essential. Here’s why:

Better Personalization: First-party data allows you to deliver experiences tailored to actual customer behavior and preferences.
Data Accuracy: Unlike purchased lists, this data is more trustworthy.
Regulatory Compliance: Consent-based data collection aligns with global privacy laws.
Future-Proof Marketing: Owning your data means you’re less dependent on external platforms that may change rules overnight.

Strategies for Building First-Party Data in 2025

Optimize Customer Sign-Ups

Encourage customers to create accounts, subscribe to newsletters, or join loyalty programs. Incentives such as exclusive travel deals, discounts, or VIP perks can significantly increase opt-ins.

For example, a travel brand could offer free eSIM trial credits for sign-ups. Learn more in The Importance of Using Local, Regional, and Global eSIMs for Travellers.

Invest in Content and Value Exchange

People won’t share data without a reason. Create high-value content, tools, or experiences that encourage engagement. Consider downloadable guides, premium newsletters, or interactive booking tools.

Use Loyalty and Rewards Programs

Loyalty programs remain one of the best ways to collect first-party data. They not only incentivize repeat purchases but also provide insights into customer preferences.

See our breakdown of Best Travel Credit Cards for International Business for an example of how rewards drive engagement.

Leverage AI for Data Activation

Once you have data, use AI to segment audiences, predict behavior, and personalize campaigns. AI-powered insights transform raw data into actionable strategies.

Strengthen Trust and Transparency

Be clear about why you’re collecting data and how it benefits the customer. Offering control through preference centers builds trust and increases willingness to share information.

Real-World Examples

Sephora’s loyalty program collects purchase and browsing data to deliver personalized product recommendations.
Airlines are designing apps that track preferences such as seating, meals, and baggage to deliver smoother, more personalized travel.
Small businesses are using email opt-ins combined with AI segmentation to run hyper-targeted campaigns without third-party cookies.

Challenges to Overcome

Transitioning to first-party data isn’t without hurdles. Businesses must invest in infrastructure, train teams, and ensure compliance with evolving privacy laws. Breaking down data silos is another challenge, as customer information is often scattered across different departments and platforms.

Final Thoughts

The era of third-party cookies is ending, but this isn’t the end of digital marketing—it’s a reset. Companies that embrace first-party data strategies will build deeper trust, deliver stronger personalization, and gain independence from shifting platform rules.

In a cookie-less world, the brands that win will be those that recognize this truth: owning your customer relationships is more powerful than renting them.
