First-party data is information a business collects directly from its own audience — purchases, site behaviour, sign-ups, preferences — through a direct relationship and, ideally, with consent. As third-party data fades, it has become the most valuable and durable asset in advertising.

How first-party data works

How first-party data works

Collect it directly. It comes from your own site, app and customers.

Get consent. It is gathered with permission and purpose.

Unify it. Signals are joined into a single customer view.

Activate it. It powers targeting, personalisation and measurement.

Where it comes from

Sign-ups. Accounts, subscriptions and forms.

Preferences. What people tell you they want.
