The metaverse is one of the most significant and innovative technological developments of recent years, having transformed and evolved customer engagement. Grounded in the Customer Engagement Theory (CET), we synthesise and integrate an understanding of customer engagement within the metaverse, given its immersive, interactive, and social features. Using the Structural Topic Modelling (STM) approach, insights were extracted from a pool of studies related to the metaverse and engagement. Twenty-five latent themes were identified and categorised into four clusters representing the different elements of CET—cognitive, emotional, and behavioural engagement. There are two additional aspects of engagement—interactive and social—particularly concerning customer engagement in the metaverse. The study's findings provide comprehension for optimising virtual engagement strategies while contributing to theory and practice in metaverse marketing.
