Key papers

Cascio Rizzo, G. L., Villarroel Ordenes, F., Pozharliev, R., De Angelis, M., & Costabile, M. (2024). How high-arousal language shapes micro- versus macro-influencers' impact. Journal of Marketing, 88(4), 107-128. What it reports: Automated analysis of text, images, video and audio from thousands of sponsored posts combined with controlled experiments. High-arousal language increased engagement for micro-influencers and decreased it for macro-influencers; the effect ran through perceived trustworthiness (higher for micro, lower for macro); for macro-influencers the penalty could be offset by pairing arousing language with positive valence or signalling an informative rather than commercial purpose.

Key ideas

Influencer Endorsement: A recommendation delivered by a social media creator whose audience sees them as an ordinary, relatable person, studied as a route to trust and purchase intention.
