First-party data
First-party data is data a company collects directly and with consent from its own users. Sources are its own website, the CRM system, the newsletter or customer accounts for instance. Unlike bought-in third-party data, it stands in a direct relationship to the company and is under its control. In the cookieless era, first-party data is gaining greatly in importance, because it is both compliant and meaningful.
Also known as: first-party data, first party data
What is first-party data?
First-party data is all the data a company gains directly from its own relationship with its users and customers. That includes behaviour on your own website, details from customer accounts, order histories, newsletter sign-ups, support enquiries or data from the CRM system. What defines it is that the data arises directly at the first party, that is, your company.
First-party data should be distinguished from second-party data, which a partner shares with you, and third-party data, which is bought in from external providers. Third-party data often rests on third-party cookies and is increasingly restricted by privacy rules and technical developments.
The decisive advantage of first-party data lies in its quality and reliability: it comes first-hand, is accurate and relates directly to your actual customer relationships.
Why does first-party data matter so much in the cookieless era?
For years digital marketing relied heavily on third-party cookies tracking users across other people's websites. Privacy rules, browser restrictions and a growing awareness of privacy have weakened that model for good, though. People speak of the cookieless era.
In this environment, first-party data becomes the central data basis. Because it is collected directly with consent, it is robust against the disappearance of third-party cookies and rests on a solid legal footing. Companies investing early in their own data thereby secure a strategic advantage.
First-party data still enables personalisation, audience building and measurement without relying on third-party Trackingmechanisms. They are therefore a cornerstone of future-proof, privacy-compliant data strategies.
What are the benefits of first-party data?
The most important advantage is data quality. Because first-party data comes directly from interaction with your users, it is current, accurate and free of the blurriness of bought-in datasets. It reflects your customers' real behaviour and is therefore a reliable basis for decisions.
Added to that is full control. You decide yourself how the data is collected, stored and used and are not dependent on the availability or quality of external sources. That reduces risk and makes your data strategy more reliable.
Finally, first-party data often enjoys greater trust, because the relationship between user and company is transparent. It is used for personalisation, sound Web analytics, building your own audiences and calculating metrics such as the Customer lifetime value.
How do companies build first-party data?
Building it starts with touchpoints where users leave data voluntarily. That includes customer accounts, newsletter sign-ups, gated content such as whitepapers, surveys, prize draws or loyalty programmes. Each of these contacts is an opportunity to gain data in exchange for recognisable value.
Equally important is clean tracking of behaviour on your own website, for instance via first-party cookies and a privacy-compliant web analytics system. Tools such as Matomo or Google Analytics 4 can be configured to rely mainly on first-party data.
To turn individual data points into a usable overall picture, the sources have to be merged, for instance in a CRM or a customer data platform. Only central, consistent consolidation makes first-party data truly valuable.
What role do data protection and consent play?
First-party data is only a solid foundation if it is collected lawfully. Your own data is subject to the GDPR too. For collection and use you need a suitable legal basis, in many cases users’ consent, obtained through a Consent management is obtained and documented.
Transparency brings a double benefit here: communicating openly which data is collected for what purpose strengthens trust and at the same time raises users' willingness to share data. Data protection is therefore not an obstacle but a mark of quality and trust in your data strategy.
At Elisabit we help companies build a first-party data strategy that unites data quality and data protection. From concept through implementing GDPR-compliant tracking to a Performance audit of your existing data collection, we lay the basis for sustainable, data-driven marketing.
How do you use first-party data effectively?
Data collected only shows its value through use. First-party data can be used to personalise content and offers, build precise audiences and steer campaigns. That way you address users more relevantly and raise your marketing's efficiency.
It is also the basis for reliable analysis and forecasting, predicting churn or identifying valuable customer segments for instance. Combined with server-side tracking and a clean data architecture, that creates a future-proof foundation working independently of third-party cookies.
Frequently asked questions
What is the difference between first-party and third-party data?
First-party data you collect directly from your own relationship with your users, through the website, CRM or newsletter for instance. Third-party data is bought in from external providers and often rests on third-party cookies. First-party data is more accurate, easier to control and more robust in data protection terms.
Why is first-party data becoming more important?
Privacy rules and browser restrictions are weakening third-party cookies steadily, which is called the cookieless era. First-party data rests on a solid legal footing and stays usable regardless of those restrictions. It thus becomes the central data basis of modern marketing.
How do I collect first-party data lawfully?
Your own data is subject to the GDPR too and needs a suitable legal basis, often consent. You obtain and document that through consent management. Transparent communication about the purpose and scope of collection also raises users' willingness to share data.
Which tools help build first-party data?
Web analytics systems such as Google Analytics 4 or Matomo are suitable for collection, ideally based on first-party cookies. CRM systems or customer data platforms are used for merging and using the data. Server-side tracking further increases the robustness of data collection.
What can I use first-party data for?
First-party data suits personalisation, building your own audiences, sound analysis and calculating metrics such as customer lifetime value. It improves the relevance of your messaging and the efficiency of your marketing without depending on someone else's tracking.
