Drafting a listing title, bullets, and description from real specs
A new SKU or a tired listing means staring at a blank detail page, and writing the title, five bullets, and a description is the single most common thing sellers hand to AI (34% use it mainly for this). The catch is that every line is an advertising claim: a wrong measurement, material, or compatibility spec turns into a return and a one-star review. The fix is grounding — feed the model only your real spec sheet so it arranges the copy without inventing facts.
You are a listing copywriter for {{marketplace}}. Write a product listing I will edit — not final copy — for the product below. Product type: {{product_type}} Verified spec sheet — the ONLY facts, measurements, materials, and compatibility you may use: {{specs}} Target keywords to work in naturally (do not keyword-stuff): {{keywords}} Produce: - A title in the marketplace's format and character limit, leading with the brand and the most-searched attributes. - Five benefit-led bullet points, each tied to a real feature from the spec sheet. - A short description (100-150 words) in plain, scannable language. Rules: - Use only the specs I provided. Do not invent measurements, materials, weights, certifications, "compatible with" claims, or what's in the box. If a stronger line needs a fact I didn't give you, write [VERIFY: what to confirm] instead of stating it. - Make no prohibited claims: no medical, health, or "cures/treats" language; no "best," "#1," or "top-rated" superlatives; no "Made in USA" or safety-certification claim unless it appears in my specs. - Match the marketplace's native style and avoid hype words like "revolutionary" or "game-changing." - After the listing, list every claim a human should substantiate before it goes live.
Fill in your details and the prompt updates live — then copy.
Title: BrandName 32 oz Insulated Water Bottle — Double-Wall Stainless Steel, Fits Car Cup Holders, Cold 24 Hrs Bullets: - COLD 24 HOURS, HOT 12: Double-wall vacuum insulation keeps drinks cold up to 24 hours and hot up to 12. - FITS YOUR CUP HOLDER: 3.5-inch base slides into standard car cup holders. Claims to substantiate before publishing: the 24h/12h temperature figures (confirm against your test data); [VERIFY: whether the lid is leak-proof — not in the spec sheet, don't claim it].
The full workflow
- Paste the manufacturer spec sheet, not your memory of the product — every claim should trace to it
- Run the prompt, then check each measurement, material, and compatibility line against the source spec
- Resolve every [VERIFY] flag and delete any claim you can't document
- Confirm the title and bullets fit the marketplace's real character limits in the listing editor
- Compare against the actual product photos so the copy and images never contradict each other
Watch out for
Amazon treats AI-written content as if you wrote it by hand — you are liable for every claim. A wrong measurement, material, or 'compatible with' spec drives returns, negative reviews, and listing suppression, so verify each one against the manufacturer spec sheet before publishing.
AI adds prohibited claims that read as plausible: medical or 'cures' language, 'best' and '#1' superlatives, or an unsubstantiated 'Made in USA.' The FTC warned marketplaces in 2025 that unsubstantiated origin claims can create liability, so cut any claim your documentation can't back.
