Signal loss –
attention win

Datalicious Podcast S6E3

What is truly lost, and how users give feedback

In the latest episode of Datalicious, Carsten Sander and his guests Christian Zimmer (Managing Director of Welect GmbH) and Olaf Peters-Kim (Managing Director and Co‑Founder of Welect) explore why the most valuable advertising signals aren’t calculated: they’re voluntarily provided by users. The focus is on “real-time intent” – a model in which users themselves choose which ads they see – as well as the far-reaching implications of signal loss, which extend far beyond the topic of cookieless advertising. In addition, the three experts discuss how user-centric approaches can strengthen the open web, and take an optimistic look at the advertising industry in 2030.

Topics in this episode:

  • Choice-driven advertising and real-time intent: How does an advertising model work in which users select which ads they see – and why is this voluntary data point more valuable than algorithmically-determined audience signals?
  • Signal loss is more than cookieless: Why does the loss of targeting data in the digital advertising ecosystem go far beyond the end of third-party cookies – and what role do ad blockers, privacy modes, tracking blockers, and IDFA opt-outs play?
  • Advertising impact through self-determination: How do the principles of recency and receptivity influence attention and willingness to buy, when users actively choose an advertisement rather than having it forced on them?
  • The open web, walled gardens, and a look ahead to 2030: How can the open web be strengthened vis-à-vis the big tech platforms – and what role do identifier solutions, AI, and user-centric approaches play in the future of digital advertising?

Key takeaways

  1. The user is the strongest advertising signal. So-called real-time intent – the user’s active, voluntary selection of an advertisement – combines recency, receptivity, and natural frequency capping. No algorithm can capture a person’s situational intent as precisely as their own decision does.
  2. Signal loss affects around 50 percent of traffic, but only about 20 percent of signal loss is due to the elimination of third-party cookies. Ad blockers, privacy modes, tracking blockers, and IDFA opt-outs collectively ensure that half of all traffic in Germany is no longer addressable. In Switzerland, this figure is as high as 70 percent.
  3. Non-addressable traffic is not worthless. Choice-driven advertising models open up incremental reach in audiences that are off limits to conventional targeting – with demonstrably higher advertising impact: willingness to buy +17%, liking +36%, message comprehension +35%.
  4. People remain the key constant: Technologies come and go, but it’s the users who decide which ones prevail. The industry should move away from groupthink and instead embrace user-centered innovation more boldly – using AI as a support, not as a substitute for human behavior.
