There are several risks associated with TikTok influencer marketing. Firstly, influencers may fail to represent the brand accurately or may act up, damaging the brand's reputation. Secondly, influencers may not disclose sponsored content, which could result in legal and ethical consequences. Thirdly, relying solely on TikTok influencers for marketing can limit a brand's reach to a specific segment, potentially neglecting other valuable audience demographics.
