The Quick Guide to Zero-Party Data for E-Commerce

By parcelLab Team 6 min read

In recent years, marketers have relied heavily on third-party data -- information collected about potential customers and sold to advertisers for targeting purposes. But a new approach is emerging that's more cost-effective, more direct, and more tied to actual customer preferences: zero-party data.

What Is Zero-Party Data?

The industry has utilized second-party data (collected by one company and shared with another) and first-party data (conclusions drawn from customers' behavior and brand interactions). Zero-party data represents the next evolution: information customers actively choose to share with brands intentionally.

Why It Matters Right Now

Legislative Changes

The 2018 GDPR and CCPA established restrictions on data collection and tracking. Subsequently, over 160 consumer privacy bills were introduced across 38 U.S. states. Tech companies have responded -- Apple blocks third-party cookies in Safari, with Google Chrome planning similar changes.

Consumer Demand

79% of Americans worry about how companies use their data, with increasing adoption of ad blockers and cookie deletion practices.

Data Quality Issues

E-commerce retailers recognize that third-party data can be unreliable. 49% of consumers say they're frustrated by irrelevant content and offers.

Zero-Party Data and E-Commerce

Zero-party data offers e-commerce businesses improved customer understanding and significant potential for increased satisfaction, repeat purchases, and lifetime value. Successful implementation requires strategic adjustments:

  • Start small: Request only essential information initially, building profiles gradually to avoid overwhelming customers.
  • Stay focused: Collect data exclusively for personalization and targeted rewards.
  • Keep communicating: Zero-party data collection extends throughout the post-purchase journey, using every touchpoint to deepen customer understanding.
  • Be transparent: Clearly explain what data you need, why it's collected, and how it will be protected.
  • Offer instant rewards: Provide short-term incentives like discounts, sweepstakes, or early product access to demonstrate appreciation.

When executed correctly, zero-party data creates a positive feedback loop: improved communication leads to deeper customer insights, enabling more relevant messaging that strengthens the relationship further.
