Analyzing real-world TikTok livestreams and validating the findings through controlled experiments, the researchers also show that customer engagement, facial attractiveness and expressive body movement amplify the effectiveness of these benefit appeals. The findings provide practical guidance for brands and creators looking to improve livestream performance.

Finding the Right Frequency: What Ad Repetition Means for Attention Across TV Platforms

  • JOURNAL OF ADVERTISING RESEARCH

How many times should consumers see the same television ad? This Journal of Advertising Research study explores how repeated ad exposures affect viewer attention across Connected TV (CTV) and Linear TV (LTV). Using second-by-second attention data collected from more than 1,300 viewers over nearly a year, the researchers find that while repeated advertising reduces attention on both platforms, the decline is significantly steeper in CTV—especially when the same ads are shown repeatedly within short time periods. The findings offer important guidance for advertisers seeking to balance frequency with engagement.

Striking the Right Balance in AI-Personalized Advertising

  • JOURNAL OF ADVERTISING RESEARCH

Generative AI is opening new possibilities for hyper-personalized advertising, including the ability to create AI-generated faces that closely resemble individual consumers. But how similar is too similar? This Journal of Advertising Research study finds that while moderate facial resemblance can improve advertising effectiveness, excessive similarity may backfire. The research introduces a new framework for measuring facial similarity and identifies an optimal personalization threshold that maximizes purchase intentions while avoiding consumer discomfort and resistance.

The Co-Viewing Advantage: Maximizing Attention Across TV Platforms

  • JOURNAL OF ADVERTISING RESEARCH

Watching television is often a shared experience, but how does co-viewing affect audience attention? An analysis of nearly 25 billion seconds of TV viewing data reveals that watching with others decreases attention to advertisements while increasing attention to programming. The effects vary by platform, with linear TV outperforming CTV in sustaining attention during co-viewing situations. The study also finds that longer co-viewing sessions strengthen engagement, while longer ads can undermine attention. These findings offer important guidance for advertisers, content creators and media planners seeking to maximize audience engagement in an increasingly fragmented television landscape.

Do People Around the World React to Advertising in the Same Way? This Study Investigates

  • JOURNAL OF ADVERTISING RESEARCH

Can facial expressions reliably reveal emotional responses to advertising across cultures? A new study published in the Journal of Advertising Research suggests the answer is yes. Drawing on a massive global database of more than 70,000 advertising studies and nearly 3.8 million frames of viewer facial responses, the authors found remarkably consistent facial expression patterns across 12 world regions. The study provides evidence that certain expressions linked to happiness, disgust, surprise and awe appear universally in response to advertising and entertainment content—supporting the use of automated facial coding as a valuable tool in global advertising research and creative testing.

Why Virtual Influencers Struggle to Drive Engagement

  • ARF
  • JOURNAL OF ADVERTISING RESEARCH

New research reveals that virtual influencers, despite their growing popularity and flexibility, are less effective than human influencers in driving engagement and brand outcomes. The reason lies in consumer psychology: people perceive virtual influencers as less deserving of success, which reduces feelings of envy—an emotion that typically drives social media engagement. However, this disadvantage can be mitigated when virtual influencers are paired with futuristic, technology-focused brands, where their artificial nature feels more congruent.
