Shift to First-Party Data Reshapes Marketing Amid Privacy Concerns

As privacy regulations tighten and consumer awareness of data misuse grows, the marketing industry is undergoing a seismic shift toward first-party data. With third-party cookies being phased out by major browsers like Google Chrome, marketers are pivoting to first-party data strategies to maintain personalized advertising while respecting consumer privacy.

This transition, driven by regulations like GDPR and CCPA, is redefining how brands engage with audiences, offering both opportunities and challenges.

What is First-Party Data?

First-party data is information a company collects directly from its customers through owned channels, such as website visits, purchase histories, email sign-ups, or loyalty programs. Unlike third-party data, which is aggregated by external providers and often lacks transparency, first-party data is accurate, consensual, and privacy-compliant. It includes behavioral data (e.g., pages viewed), demographic details (e.g., age), and transactional records (e.g., past purchases). According to a 2022 Acquia report, 88% of marketers view first-party data as critical due to its reliability and direct connection to customers.

Impact on Marketing: Opportunities and Challenges

The shift to first-party data empowers marketers to deliver highly personalized experiences, fostering trust and loyalty. Brands using first-party data report a 2.9 times revenue increase and 1.5 times cost savings, according to a Google and BCG study, as targeted campaigns reduce wasteful ad spending. However, challenges include the resource-intensive process of collecting and integrating data across siloed systems like CRMs and analytics platforms. Smaller brands may struggle with limited data scale, risking skewed insights. Additionally, maintaining compliance with evolving privacy laws requires robust governance, as 81% of consumers feel they lack control over their data, according to CMSWire. Over-personalization also risks alienating customers if it is perceived as intrusive.

Kroger Precision Marketing: Kroger, a U.S. grocery giant, leverages its loyalty program to collect first-party data, enabling precise ad targeting on connected TV (CTV) platforms. Christine Foster, VP at Kroger Precision Marketing, notes that first-party data is “the most trusted and effective means to reach relevant audiences,” especially in a cookieless CTV environment. A 2024 campaign with Strategus saw Kroger use first-party data to boost ad relevance, achieving a 20% increase in customer engagement.

Trustmark Bank with KORTX: Trustmark Bank employed KORTX’s Axon Audience Manager to harness first-party data, targeting high-fit customers with personalized messaging. The campaign yielded a 98% video completion rate and a 0.2% click-through rate, demonstrating how first-party data enhances campaign precision and ROI. By owning its data, Trustmark avoided reliance on unreliable third-party sources, ensuring compliance and trust.

E-commerce Slippers Retailer: A Bazaarvoice case study highlights an e-commerce store selling stylized slippers that severed ties with its third-party data vendor to build a first-party data strategy. By prompting website visitors for email and phone numbers in exchange for a 20% discount, the retailer tailored rewards based on purchase history, increasing customer retention by 15% and driving repeat purchases through a loyalty program.

As third-party cookies fade, first-party data is the cornerstone of privacy-first marketing. Posts on X reflect this sentiment, with users like @krizzsoni emphasizing ethical data strategies via email and CRM. Brands must invest in customer data platforms (CDPs) and consent management tools to navigate this landscape, balancing personalization with privacy to build lasting consumer trust.
