Theoretical framework – This study draws upon influencer marketing, social media influencer (SMI) literature, and digital engagement.
Design/methodology/approach – A data mining approach was used. The methodology includes the collection of video post characteristics, engagement metrics, and audio transcriptions from 34,563 videos on 103 YouTube channels.

Politics, Economy & News, Entertainment/General, and Gaming have high percentages of negative valence.
Practical & social implications of research – The results provide a deep understanding of YouTube’s popular content and digital engagement rates. This is essential for companies and SMIs looking to maximize their reach, resonate with their target audience, and stay competitive in the dynamic digital landscape. It allows for more effective communication, content creation, and strategic decision-making.
