What does attention actually tell us about whether advertising is working?
Pete Wallace, Managing Director EMEA at GumGum, explains why clicks remain a poor measure of advertising effectiveness and how attention can help marketers connect media exposure with real brand outcomes.
Pete shares how GumGum combines contextual signals, attention data, time, device and creative performance to predict the mindset of an audience. He brings this to life through GumGum’s work with the BBC and Havas on *Celebrity Traitors*, where targeting and creative changed as tension and excitement around the programme developed.
We also discuss why there is no universal number of seconds that guarantees attention, how creative testing can reveal when branding should appear, and why advertising needs to respect the environment in which it appears.
The conversation then moves into privacy, the value exchange between advertising and free content, the problem with ad tech companies using the same language, and why marketers need to ask more difficult questions about the technology behind their media plans.
Pete also reflects on moving from agency life into ad tech and leading teams across Europe, Japan and Australia, where different cultures require different approaches to pitching, testing and decision-making.
