Native beats polished
The For You feed shows brand videos between creators' videos, and anything that looks like a television spot squeezed into vertical gets swiped past. Native means framing and pace that match the feed: a face or hands in shot, on-screen text styled like TikTok's own, quick cuts, and a hook that states the point before any logo. Generation earns its place in the volume underneath: alternative hooks, text overlays, product shots, languages and cut-downs. Synthetic presenters that look almost real tend to start a comment thread about whether the video is AI, and that thread takes over, so use real people where trust is the point.
Sound is half the brief
TikTok is built as a sound-on platform, so audio belongs in the brief alongside the picture: voice, music bed and effects together. Business accounts see only the Commercial Music Library in the editor, because the general library is licensed for personal use; a trending track from outside it can get a brand video muted or removed. Commercial Sounds are cleared for use on TikTok, not for the same edit on Instagram or YouTube, so a cross-platform cut needs its own licensed music. Voice-over is where AI helps most: one script voiced in each market's language, with timing that still lands on the cuts.
Spark Ads and creator content
Spark Ads put paid reach behind an existing organic post, either the brand's own or a creator's shared with an authorisation code, and keep its likes and comments. Non-Spark in-feed ads can run to ten minutes, but their captions cannot hold clickable links, @mentions or hashtags. Creator content is the part not to fake. A synthetic person presented as a real customer or creator is a misleading endorsement under the FTC's Endorsement Guides in the US and the CAP Code in the UK. Use real creators for testimony, and use generation for the product footage, versions and languages around them.
Labels, and the records behind them
TikTok requires creators to label realistic AI-generated content, and applies the label itself when a file carries C2PA Content Credentials. For ads, Ads Manager has a toggle stating that the ad contains AI-generated content; advertisers can use it or a clear disclaimer of their own, and undisclosed realistic AI ads can be rejected. Routine edits such as colour correction or background removal need no label. The studio keeps a per-asset record of which model made what, so a team can answer the labelling question for every video in a campaign instead of reconstructing it afterwards.
