First-party data

What is first-party data?

First-party data refers to the data a company collects directly from its own customers or visitors, through its digital channels (website, mobile app, CRM) or physical ones (stores, events). This information — such as purchasing behavior, preferences or interactions — is valuable because it is exclusive, reliable and compliant with data protection regulations.

In marketing and e-commerce, first-party data is essential for personalizing customer experiences, refining targeting strategies and optimizing campaigns. For example, a brand can use this data to recommend relevant products or tailor its messaging based on purchase history.
