Write Spark Ads Captions and Replies
Write captions for a Spark Ad and prepared replies to the comments it's likely to get, so the post keeps selling in the comments.
The Prompt
We're running [creator post] as a TikTok Spark Ad for [product]. Write three caption options under 100 characters that sound like the creator, not the brand. Then list the eight comments this ad is most likely to get — questions, doubts, and jokes — and write a short, friendly reply to each from the brand account. Flag any comment that needs a human answer.
How to use this effectively
- Write captions that sound like the creator's own voice, not the brand's — that's what keeps a Spark Ad credible.
- Prepare replies to likely comments in advance so the ad keeps selling in the comment section.
- Flag any comment involving a health, safety, or efficacy claim for a human to answer.
