How Identity Resolution Helps Businesses Prepare for a Cookieless Future

Third-Party Cookies Are Disappearingโ€”Now What?

For years, businesses relied on third-party cookies to track users, personalize marketing, and measure ad performance. But now, major browsers are phasing them out, privacy laws are tightening, and traditional tracking methods no longer work.

๐Ÿšฉ Marketers are losing visibility into customer behavior.
๐Ÿšฉ Ad targeting and retargeting strategies are breaking.
๐Ÿšฉ Attribution models are becoming less reliable.

The solution? First-party identity resolution. By unifying customer data across devices and platforms, businesses can continue tracking, targeting, and personalizing marketing without third-party cookies.

1. Why Third-Party Cookies Are Going Away

๐Ÿšฉ Privacy Regulations Are Tightening โ€“ Laws like GDPR, CCPA, and other global policies restrict cross-site tracking.

๐Ÿšฉ Tech Giants Are Killing Cookies โ€“ Google, Apple, and Mozilla are phasing out third-party cookies from browsers.

๐Ÿšฉ Consumers Want More Control โ€“ Users are rejecting invasive tracking and demanding greater transparency.

Without a replacement strategy, businesses risk losing critical customer insights, advertising efficiency, and revenue opportunities.

2. How Identity Resolution Replaces Third-Party Cookie Tracking

1. Shifts Focus from Third-Party to First-Party Data

โœ” Collects first-party data directly from customer interactions, logins, and opt-ins.
โœ” Uses hashed emails, phone numbers, and customer IDs as new privacy-safe identifiers.
โœ” Builds a persistent, cookieless identity graph that businesses control.

2. Enables Cross-Device & Cross-Platform Tracking Without Cookies

3. Powers Privacy-Compliant Personalization & Targeting

๐Ÿšฉ Customer tracking will break, reducing personalization effectiveness.
