Posting consistently on Instagram, TikTok, and Facebook is one of the highest-leverage things a Shopify store can do — and one of the easiest to fall behind on. Between sourcing products, answering customer emails, and running ads, “write today’s caption” is usually the first thing to get skipped. AI closes that gap: with the right prompts, you can turn one product photo or one idea into a week of on-brand content in under 20 minutes.
This guide gives you ready-to-use prompts for the content types that actually drive traffic and sales for e-commerce brands — not generic “10 tips” posts, but captions, hooks, and calendars built around your products.
Part 1: Product Spotlight Captions
Product posts are the backbone of an e-commerce social feed. These prompts turn a single product into three distinct angles so your feed doesn’t feel repetitive.
- The Benefit-First Caption: “Write an Instagram caption for [Product Name] that leads with the single biggest benefit for [Target Customer]. Keep it under 125 characters before the ‘more’ cutoff, end with a question, and suggest 5 relevant hashtags.”
- The Story-Driven Caption: “Write a short caption (3-4 sentences) telling the story of why we created [Product Name] or the problem it solves. Tone: [e.g., warm and personal].”
- The Social Proof Caption: “Write a caption featuring this customer quote: ‘[Paste Review]’. Frame it as a mini case study and end with a soft CTA to shop the product.”
Part 2: Short-Form Video Hooks (Reels & TikTok)
The first 2 seconds decide whether someone keeps watching. These prompts generate hooks specifically, which you can then film against.
- The Pattern Interrupt Hook: “Generate 8 short-form video hook lines (under 10 words each) for a video about [Product/Topic]. Use pattern-interrupt techniques like ‘Stop scrolling if you [pain point]’ or ‘Nobody tells you this about [category].'”
- The Before/After Script: “Write a 30-second video script structured as before/after for [Product Name]. Describe the ‘before’ frustration in the first 5 seconds, then the transformation the product provides.”
- The ‘POV’ Script: “Write a POV-style TikTok script from the perspective of [Target Customer, e.g., ‘a busy mom discovering this product for the first time’]. Keep it under 45 seconds when read aloud.”
Part 3: Weekly Content Calendar Generator
Batch-planning a week at once is faster than deciding what to post every morning.
- The 7-Day Calendar Prompt: “Act as a social media strategist for a Shopify store selling [Your Niche]. Create a 7-day content calendar with a mix of product posts, behind-the-scenes, customer proof, and educational content. For each day, give a content type, a one-line concept, and a suggested caption hook.”
Part 4: Engagement & Community Prompts
- The Poll/Question Post: “Generate 5 poll or open-question post ideas for [Your Niche] designed to boost comments and shares, not just likes.”
- The Comment Reply Assistant: “Here are 5 customer comments on a recent post: [Paste Comments]. Write on-brand, friendly replies to each that encourage further engagement or a purchase where relevant.”
Getting the Most Out of These Prompts
The output is only as good as the specificity you give the AI. Always fill in real product names, real customer language (pull it straight from reviews), and a clear tone description — “friendly” means something different for a skincare brand than for a hardware store. Generate 3-5 variations per prompt and pick the one that sounds most like your brand, rather than posting the first draft.
Frequently Asked Questions
How much social content can I realistically generate in one session?
Using the calendar prompt plus 2-3 follow-up prompts per day’s concept, a full week of captions and video scripts typically takes 30-45 minutes, including light editing.
Will AI-written captions sound generic?
Only if the prompt is generic. Feeding in specific product details, real customer quotes, and a defined tone (with examples of your past best-performing posts) produces copy that sounds like your brand, not a template.
Do these prompts work for Facebook and Pinterest too?
Yes — the caption prompts translate directly. For Pinterest, ask the AI to also generate a keyword-rich pin title and description, since Pinterest functions more like a search engine than a social feed.
