Selection standard
Recent short-video rhythm, real engagement, product context, and batch reliability.
Rights rule
TikTok publishing, Spark Ads, download/editing, and brand reuse are separate.
Cost factors
Creator count, video count, samples, revisions, asset delivery, and paid-media rights.
Key risk
Expecting virality from a low budget or removing natural creator language for consistency.
Common failure
Not aligning each video hypothesis with the landing page, leaving nothing comparable.
Preparation
Product claim, sample volume, restricted claims, target audience, asset use, and launch window.
