What is first-party data?
First-party data is information a business collects directly from its own customers, visitors, and audience. It includes website behavior, purchases, form submissions, and email engagement. You own it, and it comes with the person's direct relationship to you.

What counts as first-party data
Examples include pages viewed on your site, items bought, email sign-ups, support conversations, and CRM records. You collect it through your own channels.
It differs from second-party data, which is another company's first-party data shared with you, and from third-party data bought from outside sources.
Why it has become more valuable
As browsers limit third-party cookies and privacy rules tighten, outside data gets harder to use. First-party data stays under your control and tends to be more relevant to your business.
You can use it for audience lists, conversion tracking, personalization, and measurement.
Using it responsibly
Tell people what you collect and why, get consent where it's required, and store the data securely. Good collection habits and clean records matter as much as the volume you gather.
Common questions
What's the difference between first-party and third-party data?
First-party data comes straight from your own audience. Third-party data is gathered by outside companies and sold or shared more widely.
How do I collect more first-party data?
Offer clear value in exchange for sign-ups, such as useful content, tools, or offers. Then make sure your tracking and forms capture the data accurately.
Is first-party data free of privacy rules?
No. Privacy laws still apply to data you collect yourself, including notice and consent requirements in many regions.
How does first-party data help with advertising?
You can upload customer lists, send conversion data back to ad platforms, and build audiences, all based on your own records.
