Zero Party Data and First-Party Data​: Know the Difference

Zero-party data, a concept developed by Forrester Research in 2018, doesn’t need to be analysed and provides straight customer information. First-party data, on the other hand, is derived from consumer behaviour, such as web activity, and calls for analysis to produce actionable insights. Although the term “first-party data” is more often used than “zero-party data,” many marketers have probably been using zero-party data since the internet’s inception.

Zero Party Data

Zero-party data is details that clients freely give businesses. Given that people voluntarily submit this information to businesses, some experts view it as a development of explicit data. Zero-party data has been recognised by experts as a tool to power tailored marketing initiatives ever since Forrester first used the term.

Organizations can get this information from a variety of places, including internet forms, surveys, polls, and membership applications. Despite the fact that some clients may voluntarily supply zero-party data for free, most businesses regard it as currency and provide a reward in exchange, such as an e-book, webinar, or discount code.

Due to the fact that it originates from actual customers, this data can provide marketers with precise audience insights. Marketers can use the data that businesses gather through polls, surveys, and form submissions to customise product suggestions, messaging, and offers for each customer. In this approach, the use of zero-party data by marketers adopts a conversational style that strengthens bonds between businesses and their clients.

First Party Data

First-party data is the behavioural data that businesses get as customers engage with their websites, apps, goods, and social media platforms in order to enhance CX. Web developers add a code to the organization’s media assets to collect this information, allowing CX teams to monitor user IP addresses, login information, browser language, timestamps, demographics, the websites they visited, etc. Then, businesses keep this data in their CRM platforms.

With the help of this information, marketers can retarget clients who have already visited the site with appropriate product adverts. It can also assist marketing teams in developing consumer segments based on demographics, products, subjects, and hobbies. Marketers can use both first-party and zero-party data to target users and further improve personalization.

Differences Between the Two

Although both zero- and first-party data aid in the personalization of marketing initiatives, there are differences between the two in data analysis, insight accuracy, and customer awareness.

  • Data Evaluation: Organizations can gain valuable business insights from zero-party data without having to evaluate it because it provides straightforward feedback directly from customers. On the other hand, companies must first examine first-party data in order to get insights.
  • Insight Precision: Since the information comes directly from the customer, zero-party data typically provides more accurate information than first-party data. With first-party data, businesses rely on a third party — the tracking pixel — to get behavioural data, which can occasionally result in unreliable insights. For instance, first-party data enables businesses to monitor which website pages users visit. However, a visitor to a website might not be very interested in the subject or goods offered there.
  • Customer Awareness: Customers knowingly and voluntarily share zero-party data. They might not be aware of the timing of first-party data collection, though. First-party cookies can only be tracked with the consent of the user, and this is required by a number of privacy laws around the world, including the GDPR of the European Union. However, many people provide their consent without completely comprehending what they are doing. First-party data can therefore start discussions regarding #dataprivacy.

Organizations must be transparent about how they gather and utilise first-party data in order to comply with #privacylaws. Organizations can create privacy policies and incorporate cookie notifications into their websites and other digital media assets to enhance transparency.
