Data collected directly from your own customers and website visitors.
First-party data is information collected directly by a business from its own customers, website visitors, or audience — with their consent. This includes website analytics, email subscriber lists, CRM data, purchase history, survey responses, and loyalty program data. First-party data is owned by the business, highly accurate, and privacy-compliant by nature. It is distinct from second-party data (a partner's first-party data shared with you) and third-party data (aggregated from external sources).
With the deprecation of third-party cookies, first-party data is increasingly the most valuable marketing asset a company can own. Businesses with rich first-party data can personalise experiences, build better audiences for advertising, and create durable competitive advantages.
A retailer's loyalty programme collects purchase history, preferences, and browsing data from 2 million opted-in customers. This first-party data powers personalised product recommendations, targeted email campaigns, and custom audiences for advertising.
Third-party cookies are being phased out by major browsers (Chrome announced a move toward Privacy Sandbox). First-party data provides an alternative that is owned, consent-based, and not vulnerable to cookie deprecation.
