Mapping the themes and Intellectual Structure of Micro-Influencers: A systematic Review and a Bibliometric-Analysis.
Synthesis in F1000Research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Social media marketing dynamics have been reshaped with the rise of micro-influencers, with the offering of community-driven and authentic brand engagement that goes beyond traditional celebrity endorsements and advertising. This study aims to systematically examine the micro-influencer research published between 2020 and 2025, focusing on identifying themes, research gaps, methodological characteristics, and providing future directions. Methods: This paper focuses on providing a thorough systematic literature review (SLR) incorporating the PRISMA protocol on micro-influencers, while identifying interdependencies and relationships. 68 research papers were derived from the Scopus database, analysed through bibliometric and content analysis. Bibliometric analysis was conducted using a combination of VOSviewer and Biblioshiny packages. Results were analysed through thematic clusters, co-occurrence, and bibliographic coupling analysis. Results: The analysis depicts a steady growth in publications accelerated with digitalisation and post-COVID consumer shift that placed a commercial value on small-scale influencers. Research is fragmented across authenticity, trust, engagement, sponsorship disclosure, and niche-domains for micro-influencers. The literature is geographically skewed towards the West and high-income Asian countries. Less longitudinal, mixed-method, andneuroscientific evidence with strong methodological concentration across quantitative survey, and computational methods was present. Algorithmic visibility, emerging platform comparisons, influencer labour, and non-commercial uses of micro-influencers were underexplored themes. Five research areas were identified from clustering. Conclusion: Despite the rapid expansions, micro-influencer literature remains theoretically fragmented and unevenly distributed. This review provides a comprehensive analysis of the literature on micro-influencers, synthesises these fragmented findings into an integrated cocneptual framework and provides implications and future research directions. Most studies focused on analysing a single platform with cross-sectional designs. This study highlights the need for thorough theoretical integration with methodological diversification, considering emerging platforms to better understand how micro influencers shape digital communication.
