Zero-Party Data: How to automate the collection of preferences that customers themselves want to tell you about?

Changes to cookie mechanisms aren’t meant to make our lives more difficult—the tracking model is simply no longer economically efficient. People have learned to ignore the ads that follow them, so advertising algorithms are no longer as accurate.

However, the basic principle remains unchanged: the one who sells best understands the customer. So if the psychology of buying hasn’t changed, let’s consider what has changed in the knowledge acquisition model.

What has changed in practice (as of 2026)

From what we see, marketing is no longer limited to search engines, but is becoming a recommendation feed, so your entire ecosystem (website, newsletter, store) must predict what will interest someone before they ask.

It can’t be done without Zero-Party Data (or at least it will be hard).

In the past, Zero-Party Data was treated as a bonus move, something added to a survey. It’s common knowledge with declarative data – you don’t ask for it, no one will give it to you, and not everyone wanted it or had the tools.

However, this is one of the few mechanisms that allow you to build a stable base of well-recognized customers regardless of what new Big Techs come up with.

In our opinion, the essence of the change in 2026 is to shift the balance between click satisfaction after clicking, where the click is First-Party Data and satisfaction is the result of using Zero-Party Data.

What exactly is Zero-Party Data?

We need to distinguish between concepts because the devil is in the details.

1. Third-Party Data: Purchased data. Almost nonexistent now, burdened with enormous error and legal risk. Open-air museum.
2. Second-Party Data: Data from other people’s databases (e.g., a business partner’s). While useful, it’s difficult to automate and has limited reach.
3. First-Party Data: Behavioral facts. “Customer visited website X at time Y.” They tell you what happened, but they don’t say why—the customer might have been on the dress website because they were looking for a gift, but they don’t wear dresses themselves.
4. Zero-Party Data: Declaration: “I’m looking for a gift for my wife, I’m looking for a budget of up to 500 $, she likes boho style.” The client provides the context, and everything is immediately clear.

Take into account that AI can now generate almost anything, so authentic information from a human is the most expensive currency.

Some numbers

-> Personalization has a real impact on purchasing decisions and prices (customers pay 1.8 times more often) – at the same time, poorly done personalization (e.g. based on guessing) frustrates 53% of recipients (Gartner, 2025).

-> 90% of marketers consider loyalty programs to be the main source of Zero-Party Data, so it is not nice to have only the core of the loyalty and retention strategy (Perxtech, 2026).

The “Asking, Not Stalking” Strategy: How to Implement It?

You’d feel rather awkward if a waiter in a restaurant asked for your name and shoe size right off the bat—and most websites with aggressive pop-ups do the same. A little more tact and patience is needed here.

Step 1: Hooking

Don’t ask for data, just give choices. For example, here on the blog, we could ask if you’re looking for tools or advice. One click, and our marketing automation system already knows which segment to place you in.

Step 2: Value Exchange

Few people will share their preferences for free – they must see a profit in it. Choose your communication wisely:

• “Tell us your skin type and we’ll send you samples perfect for you.”
• “Indicate your SEO level and we’ll adjust the difficulty of our guides.”

Step 3: Validation and Refresh

Preferences can change, but marketing automation allows for “cyclical reviews”—create a script that, for example, sends the customer a new question after six months. In a reputable marketing automation system, preference updates will automatically be saved in the contact card.

How does iPresso automate dialogue?

To prevent the collected data from lying fallow in the database, you need marketing automation that will process it.

What tools can you use:

1. Marketing Automation Scenarios

Build a path that responds to customer declarations. Let’s take the example of a sports store. A customer indicates interest in men’s hiking boots, then the system assigns them a tag.men’s_trekking_shoesand launches a dedicated campaign with these and only these products.

You don’t burn through your budget or waste your client’s time; if they’ve clearly defined what they’re looking for, that’s exactly what they want to get.

It is worth adding here that marketing automation scenarios are not limited to emails, but in combination with omnichannel they reach the recipient through the channel in which he is active – it can also be SMS, WhatsApp, push notifications.

2. Progressive forms and smart surveys

The system can recognize a returning customer. If you already know something about them (e.g., their name, their company’s industry in the case of B2B), you can ask them on their next visit about the biggest problem you can solve for them. Such a form/survey is already pre-filled with some data and makes a good impression on the customer – again, saving them time.

3. Dynamic content personalization

In iPresso, you can create a preference center where customers can select the content they’re interested in. And because the system monitors website visitors, it knows that showing a customer looking for a B2B strategy doesn’t make sense to show retail banners in B2C, and changes the web content accordingly.

Where does Zero-Party Data make a difference?

We will go through specific industries to show that this is not a theoretical concept for corporations.

E-commerce

Let’s assume you’re in a furniture store. You ask a customer what style they’re decorating their apartment in, and they reply, “Loft style.”

From now on, most (or all – your choice) of the information on the web and in other communications shows him only raw wood, metal and concrete.

A simple way to better conversion – the customer does not get through an offer that never applies to him.

B2B / SaaS

Let’s take into account the long sales cycle and choose a company that sells logistics software.

All you need is a web calculator: number of trucks, average fuel consumption, number of routes. You have your first Zero-Party data and automatically send a report showing how much the client’s company can save. And the lead is sent to CRM with a full needs profile.

Finances

A case study from one insurance company. We chose a quiz to automatically collect preferences about what risks a client might face based on their lifestyle.

As a result, we had information stored on customer cards such as: who has a dog, who lives in the suburbs, who has a fast car, who practices high-risk hobbies.

From here, it’s just a few clicks to create segments and send specific insurance policy offers to specific people.

The Psychology of Data Collection – Why Does It Work?

We need consistency. If you declare that you care about the environment, you’ll likely buy an eco-friendly product to maintain consistency with your image.

That’s why these 3 approaches work:

The principle of reciprocity
Share your preferences and we will share free knowledge.

Principle of Engagement
I’ve completed 3 questions in your quiz, so it’s a shame to interrupt now and not provide my email address at the end – otherwise I won’t know the result.

Principle of personalization
I’m not okay with the brand treating me as user number 4524. I’m okay with the brand recognizing that I’m Robert and I like Arabica from Ethiopia..

Technical challenges

The difficulty lies in integration – Zero-Party data is scattered and comes from various sources.

The solution is to build a 360-degree customer profile in one system – because if your survey tool doesn’t talk to your mailing tool, you have two semi-finished products.

Remember:

– Standardize tagging

– Ensure real-time data flow

– Take care of the database hygiene – remove contradictory declarations

SEO and AI Search in Zero-Party Data

It’s not often talked about, but Zero-Party Data helps with SEO. It’s very simple: if you have a website personalized to user preferences, time spent on the page increases, and the algorithms see that someone found what they were looking for.

This signals to the algorithms that this domain is valuable because people don’t return to search results to search further. The better you know your customer, the better you can feed the algorithms positive behavioral signals.

Is it safe?

Yes, Zero-Party Data is the purest form of legally binding data collection.

1. You have clear consent (opt-in).
2. You have a specific goal (e.g. tailoring the offer).
3. The user has full control (can change preferences at any time).

How to Get Started? Your Plan for the Next 30 Days

Don’t try to build a data empire all at once. Start small.

1. Day 1-7: Identify the single most important question a salesperson asks every customer. This is your “ZPD. #1.”
2. Day 8-14: Implement a simple form in iPresso that asks this question on the most popular subpage.
3. Day 15-21: Create two newsletter/banner variants based on the answer to this question.
4. Day 22-30: Measure the results. See if the segment that received the tailored content has a higher CTR (spoiler: it will).

Summary: The future belongs to brands that listen

Only brands that own their own data will survive. Relying on external platforms is a risk not worth taking.

Think of Zero-Party Data as a social contract between a company and an individual.We (the brand) promise not to waste your time, and you (the customer) tell us how we can do it best.

But with thousands of contacts and conversations a day, marketing automation is the only way to maintain something resembling a human connection – remember that.

FAQ – Frequently Asked Questions

1. How is Zero-Party Data different from First-Party Data in everyday marketing?

First-Party Data is behavioral data (where someone clicked). Zero-Party Data is intent data (why they clicked). Using both simultaneously allows for full personalization.

2. Can small businesses collect ZPD without large budgets?

Yes. A simple quiz in iPresso or even an email survey will suffice. The most important thing isn’t the technology, but the idea of ​​how to use this information to truly transform the customer experience.

3. What are the most common mistakes when implementing ZPD?

Collecting data that’s never used. If you ask a customer about their favorite color and then send them black-and-white emails, you lose credibility. Another mistake is making the initial form too long – break the questions down into steps.

4. Will Artificial Intelligence (AI) Replace Zero-Party Data?

Quite the opposite. AI needs good input to generate effective recommendations. ZPD is the best possible “prompt” for your marketing engine. Without customer commitment, AI is just guessing.

5. How to motivate customers to express their preferences?

“Here and now” personalization works best. “Fill out these 3 fields, and in a moment you’ll see a list of products tailored to your budget.” Immediate rewards are the most powerful motivator.

6. Does collecting ZPD slow down the website?

If you’re using modern automation platforms like iPresso, scripts are optimized for performance (asynchronous loading). The impact on SEO and load speed is negligible, while the benefits of longer user session times are enormous.

7. Can I integrate ZPD with my Facebook/Google ads?

Yes. You can send preference-based segments (e.g., “People who like Loft style”) to advertising systems as audiences. This allows your ads to become an extension of the conversation you started on the site.
