Why First-Party Data is Taking Center Stage

April 22, 2024

In the digital marketing landscape, the move from third-party cookies to first-party data is not just a trend but a strategic imperative.  Publishers must recognize the critical shift towards a cookieless advertising landscape and focus on their data strategy. With an estimated 60-70% of impressions already being cookieless due to factors like Safari, Firefox, and adblockers, and with Chrome soon to follow suit, the impact on revenue is undeniable. 

Publishers have experienced declining revenues firsthand, highlighting the urgent need to adapt to this cookieless reality. Adapex publishers using our first-party data solutions have significantly increased revenue from 3% to 18%.  Implementing these solutions provides a clear path forward amidst this evolving digital environment. It’s time for publishers to embrace innovative strategies prioritizing first-party data. Here’s why:

1. Privacy Regulations and Consumer Demand

Heightened concerns over privacy, coupled with stringent regulations like GDPR and CCPA, have spurred the demise of third-party cookies. Consumers demand transparency and control over their data, pushing brands towards ethical, consent-driven data collection methods inherent in first-party data.

2. Trust and Reliability

The opacity and unreliability of third-party data sources have eroded trust in traditional data practices. In contrast, first-party data offers authenticity, garnered directly from interactions with one’s audience, fostering trust and reliability.

3. Targeting Precision and Personalization

First-party data enables deeper insights into consumer preferences, behaviors, and intent. This fuels hyper-targeted campaigns that resonate with individual interests, leading to higher engagement rates and a more personalized user experience.

4. Increased Revenue for Publishers

Publishers stand to benefit significantly from the shift to first-party data. By leveraging their data assets, publishers can offer advertisers highly targeted and contextually relevant ad placements, commanding higher rates and attracting more advertising dollars. 

5. Long-Term Revenue Growth

Investing in first-party data strategies offers stability and sustainability compared to third-party cookies, which are subject to browser changes and regulatory crackdowns. By building direct relationships with their audience, brands future-proof their marketing efforts and unlock new revenue streams.

6. Adapting to a Cookieless Future

With major web browsers phasing out support for third-party cookies, businesses must pivot towards a first-party data strategy to stay competitive. Prioritizing the collection, analysis, and activation of first-party data assets ensures readiness for the cookieless future.


The industry’s shift to first-party data signifies a strategic response to privacy concerns, a quest for authenticity, and the pursuit of enhanced targeting capabilities. By embracing a first-party data strategy, brands can forge deeper connections with their audience, drive personalized experiences, and secure long-term success in the evolving digital landscape. Publishers, in particular, can leverage their data to attract more advertiser dollars, solidifying their position in the market.
