First-party data refers to all the information that a company collects directly from its customers through its own interactions: forms, purchase history, website navigation, surveys, loyalty programs, among others. Unlike third-party data, it is collected with the user’s consent, making it more reliable, personalized, and aligned with new privacy regulations.
With the gradual elimination of third-party cookies in browsers like Chrome and Safari, and the growing consumer awareness of digital privacy, first-party data has become one of the greatest competitive advantages in modern marketing.
According to Google’s The Effectiveness Equation report, brands that know how to properly activate this data not only improve their personalization but can even gain market share over category leaders.

What sets apart a brand that effectively uses first-party data?
Google conducted a series of studies and experiments with consumers in the United Kingdom and found that when brands use their customers’ data to offer personalized and relevant messages, they can achieve between 10 and 26 percentage points increase in brand preference, even surpassing established leading brands.
This shows that it is not just about having the data but about using it intelligently, quickly, and responsibly.
“Brands that collect relevant information but do not use it not only miss an opportunity: they are breaking an implicit promise with their consumers,” warns the Google report.
Brands that do it well build trust, foster stronger relationships, and deliver real value in every interaction.

How to effectively activate first-party data?
Collecting information is just the first step. The real challenge lies in activating that data in real time with personalized, creative messages aligned with user needs. Google highlights three key factors to achieve this:
- Speed: Brands must be agile in responding to consumer behaviors with relevant offers at the right moment.
- Context: Personalization means more than just using the customer’s name. It involves understanding their purchasing patterns, interests, and key touchpoints.
- Perceived Value: Each activation must provide something useful to the user: a recommendation, a solution, an advantage, or a clear benefit.
Tools like advanced CRMs, Customer Data Platforms (CDPs), and predictive segmentation models allow companies to turn data into more human and meaningful experiences.

What are the most common mistakes when working with first-party data?
The Google report points out several common mistakes that prevent making the most of this competitive advantage:
- Collecting for the sake of collecting: Many brands store data that they never activate. This leads to tech overload and lack of focus.
- Lack of integration: Data remains siloed within different departments (marketing, sales, customer service) without a unified customer view.
- Superficial personalization: Instead of building relevant journeys, some brands merely use the user’s name or repeat generic recommendations.
- Failing to deliver on promises: Asking for customer information and then not providing real value in return can harm trust.
To avoid these mistakes, Google recommends aligning marketing, technology, and customer service areas under a common customer-centric vision.

What role do privacy and consent play in the use of this data?
Privacy has become one of the most relevant issues for digital consumers. Proper use of first-party data not only involves complying with regulations like the GDPR or the Data Protection Law in Mexico but also actively building trust with users.
The Google report emphasizes that transparency is key: brands must be clear about what data they collect, what they use it for, and how it brings value to users in return. This strengthens the brand-customer relationship and reduces the risk of rejection or future blocks.
How can emerging brands compete with leaders using first-party data?
One of the major revelations of Google’s study is that first-party data can level the playing field. While giants in each category rely on brand recognition and large budgets, smaller brands can grow quickly if they know how to strategically use the data they already have.
With a good activation strategy, creativity, and automation, it is possible to:
- Identify high-value microsegments.
- Create personalized journeys that increase conversion rates.
- Boost retention with specific offers.
- Enhance Customer Lifetime Value (CLTV).
In other words, quality data can even surpass brand power if used intelligently and relevantly.
Are you leveraging the full potential of your first-party data?
In the face of increasingly intense competition and consumer expectations higher than ever, first-party data is not just a tactical tool: it is a strategy for sustainable growth.
Activating it correctly means understanding each customer as an individual, building genuine relationships, and delivering value at every touchpoint. Brands that manage to do this will not only survive in a cookie-less environment but will stand out for their ability to connect, build loyalty, and lead.
