With third-party cookies deprecated in Chrome and restricted in Safari and Firefox, the advertising industry is undergoing its biggest structural shift in 20 years. First-party data is your competitive moat.

What is First-Party Data?

First-party data is information your customers willingly share with you: email addresses, phone numbers, purchase history, preferences. Unlike third-party data, it belongs to you.

How to Collect It

  • Login and registration flows
  • Lead magnets and gated content
  • Loyalty programmes
  • Post-purchase surveys
  • Progressive profiling

Using It for Advertising

Upload your first-party data to Meta Custom Audiences, Google Customer Match, and TikTok Custom Audiences to match your real customers.
