Every week, hundreds, maybe thousands of potential buyers visit your online store. They browse. They leave. Most never buy.
Why? Because they can’t find what they’re looking for.
What if there was a way to know exactly what each customer wants before they even start shopping? What if they told you their preferences, budget, and needs upfront?
This is the power of zero-party data.
While other brands struggle with new privacy laws and disappearing cookies, forward-thinking eCommerce companies are doing something different. They’re asking customers to share information willingly. And customers are happy to do it.
The results speak for themselves: higher conversion rates, fewer returns, and customers who come back again and again.
So what exactly is zero-party data? And how can your brand start collecting it today?
What Is Zero-Party Data?
Zero-party data is information that customers willingly share with your brand. Unlike other data types that businesses collect secretly, zero-party data comes directly from your customers.
Forrester Research created this term. They say zero-party data is information customers share because they want something valuable back. This includes:
- Product likes and interests
- What they plan to buy
- Personal details and lifestyle info
- How they want you to contact them
- Feedback and opinions
- Quiz answers and survey responses
The significant difference? Your customers trust you enough to share this personal information. They believe it will make their experience better.
Zero-Party Data vs First-Party Data: What’s the Difference?
Many people mix up zero-party data with first-party data. But they’re different:
First-Party Data
First-party data is information you collect about customer behavior on your website. This includes:
- Pages they visit and time browsing
- What they bought before
- Email opens and clicks
- Cart abandonment patterns
You gather this data quietly as customers use your site. Useful, but you need to guess what it means.
Zero-Party Data
Customers who want to share it give zero-party data freely. Examples include:
- Answers to product recommendation quizzes
- Preference center choices
- Survey responses about shopping habits
- Wishlist items and saved favorites
Customers actively tell you what they want. They’re not leaving clues for you to figure out.

Why Are Businesses Interested in Collecting Zero-Party Data?
The move toward zero-party data isn’t just a trend. A response to the major changes in digital marketing exists:
1. Privacy Rules Are Getting Tougher
GDPR, CCPA, and other data protection laws make old data collection harder. Zero-party data collection works well with privacy rules because customers willingly share information.
2. Third-Party Cookies Are Going Away
Google plans to remove third-party cookies. This speeds up the need for direct customer relationships. Zero-party data offers a cookie-free way to understand your audience.
3. Customer Expectations Are Higher
Modern customers expect personal experiences. They’ll share information if it means getting better recommendations and more relevant content.
4. Better Data Improves Marketing Results
When customers tell you exactly what they want, your marketing becomes more targeted and effective. This leads to higher sales and happier customers.
How to Collect Zero-Party Data: 8 Proven Methods
Collecting zero-party data needs smart thinking and the right tools. Here are the best methods:
1. Product Recommendation Quizzes
Product quizzes are one of the most fun ways to collect zero party data. Customers enjoy interactive experiences that help them find products made for their needs.
A well-made product quiz can capture:
- Style preferences
- Use cases and needs
- Budget considerations
- Personal characteristics
For example, a skincare brand might ask about skin type, concerns, and routine preferences. This zero-party data helps create personal product recommendations that feel helpful, not pushy.
2. Preference Centers
Let customers specify exactly how they want to interact with your brand:
- Email frequency preferences
- Content topics they like
- Communication channels
- Product categories they value
3. Surveys and Feedback Forms
Post-purchase surveys and feedback forms capture valuable insights about customer experience and future needs. Keep them short and focused for better completion rates.
4. Account Profile Setup
Encourage customers to build detailed profiles by offering benefits like:
- Personal product recommendations
- Early access to sales
- Birthday discounts
- Custom content
5. Interactive Tools and Calculators
AI Product Finder tools and calculators provide immediate value while collecting preference data. Examples include:
- Size guides and fit finders
- Budget calculators
- Product match checkers
- Style assessment tools
6. Social Media Engagement
Use polls, questions, and interactive content on social media platforms to gather customer insights in real time. This data helps inform both product development and marketing strategy.
7. Contest and Giveaway Entries
When customers enter contests, ask for more than just contact information. Include optional questions about preferences, interests, and shopping habits.
8. Customer Reviews and Ratings
Encourage detailed reviews that include information about customer usage, preferences, and recommendations. This creates a database of zero-party data while building social proof.

How to Use Zero-Party Data for Personal Touch
Once you’ve collected zero-party data, the real magic happens in how you use it:
1. Smart Product Recommendations
Use preference data to show relevant products throughout the customer journey. If someone says they prefer eco-friendly options, show sustainable products first.
2. Personal Email Marketing
Split your email lists based on zero-party data to send highly relevant content. Customers who shared their interests get content that matches what they like.
3. Custom Website Experiences
Change your website content, navigation, and product displays based on customer profiles. Return visitors see a personal homepage that reflects their stated preferences.
4. Targeted Advertising
Use zero-party data to create similar audiences and improve ad targeting. When customers tell you what they want, you can find similar prospects more easily.
5. Product Development Insights
Zero-party data reveals gaps in your product line and opportunities for new offerings. Customer feedback directly informs business decisions.
Zero-Party Data Collection Best Practices
Make It Worth Their While
Always provide clear value in exchange for personal information. Customers should see benefits right away, like better recommendations or exclusive access.
Keep It Simple
Long forms and complex surveys reduce completion rates. Focus on the most important questions and make the experience enjoyable.
Be Clear
Explain clearly how you’ll use the data and what benefits customers will get. Being open builds trust and encourages participation.
Act on the Data
Nothing destroys trust faster than ignoring customer preferences. Use the zero-party data you collect to improve their experience every time.
Respect Privacy
Even though customers willingly share zero-party data, treat it with care. Use strong data protection measures and honor their preferences.
Can Zero-Party Data Be Used for Targeted Advertising?
Yes, zero-party data can enhance your advertising efforts while respecting customer privacy:
Audience Creation
Use zero-party data to build detailed customer personas and create similar audiences for advertising platforms.
Message Personal Touch
Change ad creative and messaging based on stated preferences and interests from your zero-party data collection.
Platform Targeting
Different customer segments prefer different platforms. Use preference data to choose the right channels for your advertising spend.
Retargeting Enhancement
Combine zero-party data with behavioral data to create more effective retargeting campaigns that speak to customer interests.
How Zero-Party Data Aligns with Privacy Rules
Zero-party data collection naturally follows privacy rules because:
Clear Consent
Customers actively choose to share information, providing clear consent for data use.
Open Process
The value exchange is obvious – customers know what they’re giving and what they’ll get back.
Control
Customers can update or remove their preferences at any time, keeping control over their data.
Purpose Limitation
Zero-party data is collected for specific, stated purposes that benefit the customer.
Building Your Zero-Party Data Strategy
1. Check Your Current Data Collection
Review your existing touchpoints and find opportunities to collect zero-party data more effectively.
2. Choose the Right Tools
Invest in platforms that make zero-party data collection engaging and seamless. Interactive quizzes and preference centers need the right technology foundation.
3. Start Small and Scale
Begin with one or two collection methods and slowly expand as you learn what works for your audience.
4. Connect Across Channels
Make sure your zero-party data flows into all customer touchpoints – email, website, advertising, and customer service.
5. Measure and Improve
Track completion rates, data quality, and business impact to keep improving your collection methods.
The Future of Zero-Party Data
As privacy rules get stricter and customer expectations grow, zero-party data will be more important for eCommerce success. Brands that master zero-party data collection will have a significant competitive advantage in understanding and serving their customers.
The key is building real relationships where customers want to share information because they trust you to use it well. This creates a positive cycle – better data leads to better experiences, which encourages more data sharing.
Conclusion
Zero-party data represents a significant shift from sneaky tracking to working together with customers. When customers willingly share their preferences and needs, both sides win. Customers get personal experiences that truly meet their needs, while brands gain accurate insights that drive better business results.
The question is not if you should collect zero-party data. The focus is on how fast you can use good collection strategies. Start with simple tools like product quizzes and preference centers. Then expand your approach as you learn what works with your audience.
Remember: the goal isn’t just to collect data. To use it in ways that truly improve the customer experience. When you get this right, zero-party data becomes the foundation for lasting customer relationships and steady business growth.
Ready to start collecting zero-party data for your eCommerce brand? Interactive product quizzes are often the most engaging starting point. They help customers discover products while sharing valuable preference information that powers personal experiences across your entire customer journey.
