These conclusions supplement the relevant theories of social media influencer video marketing, and to a certain extent make up for the gaps in the research on the influence of social media influencer video marketing on consumer purchasing decisions. Based on the above research results, this research provides suggestions in four aspects for social media influencers and managers. Finally, this research reflected on the limitations of this study and puts forward the research direction of future research.
