What Is First-Party Data?
First-party data is the data you collect directly from your audience. It’s the most valuable and privacy-compliant type of data because it comes straight from your own website, app, or communication channels—no middlemen involved.
Examples include:
- Contact form submissions
- Purchase history
- Account signups
- Page views and click events
- On-site behavior (e.g., scrolling, video plays)
Unlike third-party data, which comes from outside sources, first-party data is accurate, owned by you, and fully consent-driven.

- Build more relevant marketing campaigns
- Improve personalization and targeting

Agencies and site owners who rely on third-party data (e.g., rented email lists or vague ad targeting) are already seeing reduced performance. First-party data is the sustainable alternative.
First-Party Data on WordPress Sites
If your site runs on WordPress, you’re probably collecting first-party data already—whether you realize it or not. Common sources include:
- Form plugins like Gravity Forms, WS Form, or Contact Form 7
- Ecommerce platforms like WooCommerce
- Membership systems like MemberPress or LearnDash
- Newsletter opt-ins from ConvertKit, Mailchimp, etc.
Every time a visitor fills out a form, buys a product, or logs in, you’re generating first-party data.
The key is making sure this data is tracked, stored, and shared properly with your analytics and marketing platforms—without violating privacy.

- Second-party data is someone else’s first-party data shared with you, like a trusted partner’s email list. It can be useful, but you don’t control its collection or quality.
- Third-party data comes from external aggregators or platforms and is often less reliable, harder to verify, and riskier in terms of privacy.
