Zero-party data has very quickly become the biggest buzzword in marketing and digital advertising. Unlike third-party data, which is collected by aggregators and ad platforms through third-party cookies and unsavory tracking techniques, zero-party data is collected voluntarily and directly from customers.

Think of the kind of things you’d tell a store associate helping you find the right gifts to purchase for your family — size, style, skin concerns, gender, budget, taste profile, eating habits, what type of pet they have, etc. That’s zero-party data.

Zero-party data marketing started when the scrutiny on ad tracking ramped up, but became a necessity with iOS 14.5. With the vast majority of users opting out of data tracking on iOS, marketers need new sources of data to power their campaigns and replace the data they currently borrow from tracking cookies — which will also go away in 2023.

This is especially true as more consumers demand personalized experiences from the places they shop. Implemented correctly, zero-party data marketing allows you to treat every customer as an individual, personalize their experience with your brand and build real relationships.

While a lot of articles have discussed the importance of zero-party data, very few have gone into how to collect this valuable data and properly leverage it for better conversions, loyalty and customer satisfaction. That’s why I decided to write this piece. Think of it as a miniguide on how to begin your journey as a zero-party data marketer.

Let’s start with some of the most important tools for zero-party data collection.

Quizzes and recommendations are the backbone of zero-party data

When you hear “quiz,” you might be tempted to think of a BuzzFeed-style personality assessment, but in reality, they are the fundamental way we figure out what products we want to buy and what package to get.

Think about entering a cosmetics store. You know you need some collection of skincare products, but you don’t know which routine to follow or all the possible options for each part of the routine. A store associate does, however, and they usually help you find the right skincare routine and products based on a series of questions they ask about your skin’s condition, concerns, allergies and more.

A recommendation quiz is this interaction online. It gives your customers more confidence in their purchase and can help you collect and use zero-party data to personalize your customers’ experiences with your brand, from onboarding to post-purchase.

You can use quizzes to make an onboarding experience, a gift finder, a guided shopping experience and much more. These quizzes also have the benefit of a high conversion rate — 10% to 30%+ conversions to sale versus the average website conversion rate of 2% to 4%.

Some tips for creating a high-converting quiz that collects zero-party data:

Here are some examples of beautiful zero-party data quizzes:

Make your pop-ups conversational

Traditional pop-ups are intrusive, add no value and make no sense. Imagine walking into a store and having a store associate harass you right as you walk in, offering a 10% discount in exchange for your phone number. You’d find it very strange and likely be turned off immediately. That’s why it never happens in real life — yet it happens all the time online.

Instead of a traditional pop-up with a low conversion rate (2% to 4%), you should use a pop-up as an opportunity to help your customers and collect zero-party data in the process. That’s what a conversational pop-up does.

Think of a conversational pop-up like a quiz within a pop-up. It works in three steps:

Conversational pop-ups have endless possibilities. Here are some examples to help you get inspired:

Surveys, SMS, chatbots and more ways to ask questions

While quizzes and conversational pop-ups should be part of any zero-party data marketer’s toolkit, there are many other ways to collect zero-party data that you should explore. Here are a few other common methods:

Anytime and anywhere you can ask a customer or user a question is an opportunity to collect zero-party data.

Now that we’ve covered zero-party data collection in-depth, let’s talk about how to use the data to improve and personalize the customer experience for better conversions, sales and customer satisfaction.

Leveraging zero-party data in your marketing channels

The first thing you need to do with any zero-party data you collect is to reference it in any campaign or flow sent to a customer or prospect. A great zero-party data collection platform will integrate with the tools you use for email and SMS marketing.

Hunter & Gather, for example, implemented a quiz to gather diet preferences and recommend keto and paleo-friendly products to their customers. Then the brand used this information to personalize their email welcome series — specifically suggestions for new products they may want to try. The quiz itself garners a quiz-to-purchase conversion rate of 21%, which is well above the average on-site conversion rate of 2%.

Even more impressively, the zero-party data they collected and used to personalize their email marketing increased their owned marketing (email + SMS) revenue by 29% and increased their revenue from email flows by 258%!

Here’s a diagram of what this flow can look like, from quiz to zero-party data collection to email personalization:

Gaining advanced insights from zero-party data

There is another less tangible but perhaps even more important benefit to collecting zero-party data: the insights you gain on your customers. Doe Lashes, a multimillion dollar lash brand, uses a quiz to recommend the right lashes for its customers. One of the quiz’s questions asks how experienced their customers’ are with wearing lashes.

The Doe Lashes team assumed most of their customers were experienced with lashes. That’s why they were surprised to learn that, in fact, most visitors to their website had never bought or worn lashes before! With this information, Doe Lashes was able to create a whole new lash education sequence via email and on their website, helping them increase sales dramatically.

All of this from a single zero-party data point. What kind of insights could you gain about your business if you had more zero-party data on hand?

With new data privacy changes happening at lightning speed, it’s more critical than ever for every marketer to collect their own zero-party data and rely less on third-party data. I hope some of these tips and examples will help speed up your zero-party data journey.
