The importance of third-party data

In today’s marketing landscape, advertisers, agencies, and platforms all rely on data to shape strategies and achieve success. Specifically, trusted third-party data can influence decision-making processes, scalability, campaign optimisation, and addressing targeting challenges.

Experian recently published a report in collaboration with The Drum, casting a spotlight on the use of third-party data across the customer lifecycle. Through a series of roundtables and interviews, various stakeholders from the marketing data landscape shared their insights on third-party data. In this follow-up blog, we summarise the unique perspectives and overlapping goals of advertisers, agencies, and platforms, uncovering how they leverage third-party data to understand customers, optimise campaigns, and meet business objectives.

How are advertising agencies using third-party data?

Agencies, who plan and execute digital advertising campaigns for brands, also value a deep understanding of customers, but they must contextualise with broader consumer behaviour to develop insights and deliver effective campaigns. Agency perspectives include:

  • Effective Planning: Third-party data assists advertising agencies in upfront planning, enabling them to develop strategies that resonate with the target audience and drive impactful campaigns from the start
  • Optimised Campaign Performance: During campaign execution, leveraging third-party data allows agencies to optimise performance by refining audience targeting, improving message relevance, and enhancing overall campaign effectiveness
  • Valuable Insights and Continuous Improvement: Third-party data provides valuable insights that fuel future learnings, audience targeting, and campaign planning. By analysing the data generated throughout the customer journey, agencies establish a continuous improvement loop, making data-driven decisions and refining strategies over time

What do platforms think of third-party data?

Platforms (for example social media, CTV, DSP, and programmatic) play a vital role in meeting the data needs of advertisers and agencies, while also exploring the potential value of other data sources. The platform perspectives include:

  • Maximizing First-Party Data: Platforms leverage third-party data signals to make first-party data work harder, minimising wastage, and improving accuracy in targeting
  • Enhanced Reach and Engagement: Third-party data enables platforms to effectively reach users who are more likely to engage with the brands’ products or services, particularly at scale. This particularly powerful in the realm of Connected TV (CTV), which combines digital targeting advantages with the mass reach of traditional television advertising
  • Addressing Targeting Challenges: For brands with limited first-party data third-party data provides invaluable for platforms and effectively target audiences, addressing the challenges of audience identification and engagement

Overall, stakeholders across the marketing data ecosystem recognise the continued importance of third-party data in understanding consumers, improving campaign performance, and meeting broader business objectives. Advertisers emphasize scale and speed, advertising agencies focus on present optimisation and future insights, while platforms aim to maximise the effectiveness of first-party data and address targeting challenges. By harnessing the power of third-party data, stakeholders can unlock new opportunities and drive remarkable marketing results.
