AI Prompt for Sale Social Captions
Sale social media captions: Social sales need thumb-stopping brevity. This AI prompt for ecommerce writes sale captions for Instagram, TikTok and Facebook.
The prompt
You are a social commerce copywriter. You write for thumbs, not desks: short, visual, and comment-baiting. Context: [STORE_NAME] sale: [OFFER], [DATES], code [CODE], link [LINK]. Hero product: [HERO_PRODUCT]. Buyer: [TARGET_CUSTOMER]. Brand voice: [BRAND_VOICE]. Platforms: Instagram, TikTok, Facebook. Task: Write: (1) an Instagram caption (under 120 words, hook in first line, hashtags: 5 targeted), (2) a TikTok script hook + caption (the first 3 seconds as text, under 30 words total), (3) a Facebook post (under 80 words, comment-prompt question at the end), (4) 3 story-text overlays (under 8 words each). Format: Labeled by platform. Constraints: - The offer and code appear in every version - social viewers won't hunt. - First line must stop the scroll; no "exciting news" openers. - Hashtags: 5 targeted niche tags, not 30 generic ones. - TikTok hook must work as on-screen text in 3 seconds. - Facebook ends with a genuine question, not engagement bait.
Variables to fill in
Replace each [variable] in the prompt with your own details:
[STORE_NAME] [OFFER] [DATES] [CODE] [LINK] [HERO_PRODUCT] [TARGET_CUSTOMER] [BRAND_VOICE]
Example input
STORE_NAME: Ember & Oak | OFFER: 20% off cast iron | DATES: this weekend | CODE: SEAR20 | LINK: emberandoak.com/sale | HERO_PRODUCT: 12-inch skillet | TARGET_CUSTOMER: home cooks | BRAND_VOICE: warm, craftsmanlike
How to use this prompt
Pin the sale post and update the link in bio before posting. Social traffic bounces fast when the link doesn't match the caption's promise.
Tips for the best results
- Show the hero product in the first frame/image - product-first beats logo-first on every platform.
- The comment question should be answerable in 3 seconds ('cast iron or carbon steel?') - low effort, high replies.
- Repost top-performing sale creatives as ads; organic winners usually win paid too.
Frequently asked questions
How often should I post about a sale?
Once per platform at launch, once at the midpoint, once for last call. More feels spammy; less wastes the event.
Do hashtags still matter?
Less than they did, but 3-5 targeted ones still help discovery on Instagram and TikTok. Quality over quantity.
