How to Use AI to Write Product Descriptions That Sell

Whether you sell on your own website, Etsy, Amazon or a local marketplace, product descriptions matter. They answer shoppers’ questions, help your pages appear in search, and can be the difference between “add to basket” and “back”. Writing dozens of them by hand, though, is slow.

AI can draft descriptions quickly and in a consistent style. The key is to feed it accurate product facts, so it sells honestly rather than inventing features.

What you’ll need

• Accurate product details: dimensions, materials, ingredients, compatibility, care
• Your tone of voice (one or two example descriptions you like)
• A main keyword for each product (what a shopper would type into search)
• An AI chatbot. For many products, a spreadsheet of details.

Step-by-step: write product descriptions with AI

1. Build a fact sheet. For each product, list the facts in a spreadsheet: name, category, materials, size, colour options, key features, who it’s for, care instructions, price band. Facts in, facts out.
2. Define a structure. A common, effective layout is a one- or two-sentence hook, 3–5 benefit-led bullet points, then a practical “details” section (size, materials, care, delivery).
3. Pick a keyword. Choose the phrase shoppers use, such as “linen tea towel” rather than “artisan kitchen textile”. Ask the AI to use it naturally in the title and first sentence.
4. Write one, perfect it. Use prompt 1 on a single product and edit it until you love it. This becomes your style example.
5. Scale up in batches. Paste 5–10 products at a time from your spreadsheet with your perfected example (prompt 2). Larger batches tend to drift in quality.
6. Fact-check every one. Remove any feature, certification or claim that isn’t true, such as “waterproof”, “organic”, “hypoallergenic” or “handmade”. False claims can break consumer law and platform rules.
7. Write SEO extras. Ask for meta titles, meta descriptions and image alt text (prompt 3).
8. Test and improve. Watch which products convert well and ask the AI to rewrite weak performers with a different angle.

• Canva: product photo backgrounds, mock-ups and listing graphics.

Tips and mistakes to avoid

• Don’t let AI invent features. It may assume a bag is waterproof or a cream is natural. Always verify.
• Avoid copying competitors. Don’t paste a rival’s description and ask for a rewrite. Write from your own facts.
• Don’t keyword-stuff. Use the keyword naturally once or twice. Write for people first.
• Keep it scannable. Shoppers skim, so bullets and short paragraphs help.
• Health and safety claims need care. For cosmetics, food, toys or supplements, there are strict rules on what you can claim. Check the regulations for your market.

FAQ

Does Google penalise AI-written product descriptions?

Google has said it focuses on content quality, not how it was produced. Unique, helpful and accurate descriptions are what count. Mass-produced, thin content is the risk.

How long should a product description be?

Long enough to answer a shopper’s key questions. For simple items that may be 80–150 words. Complex or expensive products often need more.

Can AI write descriptions from a photo?

Multimodal tools like ChatGPT, Claude and Gemini can describe what’s in a photo, which is a useful start, but they can’t know materials or dimensions. Add those facts yourself.
