CTA (Call-to-Action) in Video
Definition
The line that tells a viewer what to do next. Follow, comment, tap the link, or buy. It usually lives in the last three to five seconds, and it works better when the ask is small and specific than when it is broad and polite.
Placement is a geometry problem before it is a copy problem. On a 9:16 video the bottom 18% of the frame belongs to the platform: caption text, the username, the progress bar, and whatever pinned comment happens to be showing. The right 12% is the like and share column. Burn "link in bio" into either strip and a share of your audience reads it through TikTok's own interface. On-screen CTA text belongs in the middle band, above the bottom fifth.
Timing is simpler than placement. The last three to five seconds is the standard slot, because a viewer who got that far has already decided they like you. Some formats also put a soft ask up front, and that usually costs more retention than it earns follows.
Then the copy. "Follow for more tips" asks for a commitment and names nothing in return, which is why it converts badly. "Comment BUDGET and I'll send you the sheet" converts, because the ask is one word long and the reward is specific. The pattern is a small action with a named payoff, and exactly one ask. Stacking a follow, a like, a comment, and a link into the same four seconds gets you none of them.
Match the ask to the goal. Comments cost the viewer almost nothing and feed the ranking signal directly, which is why they are the sensible default. Link clicks are the most expensive thing you can request inside a feed built to punish anything that sends people out of the app, which is how link-in-bio survives despite being a genuinely bad experience.
When Orange drafts a script the CTA is written into the closing scene from the start rather than bolted on at the end, so the last line already knows what the first line promised.
