Tik Tok's new Creator Marketplace API allows partnered marketing companies to access TikTok’s first-party data about audience demographics, growth trends, best-performing videos and real-time campaign reporting (e.g. views, likes, shares, comments, engagement, etc.).
Creator marketplaces are now common to social media platforms with large influencer communities as this has become a standard way to advertise to online consumers, particularly the younger generation.
These type of in-house platforms make it easier for marketers to work with the wider influencer community by offering trusted data on metrics that matter to brands’ own ROI, rather than relying on self-reported data from influencers or on data they have to manually collect themselves. And as campaigns run, marketers can compare how well their partnered creators are able to drive results to inform their future collaborations.
