Best AI Prompts for Product Descriptions (2026)
Prompts for product descriptions#
Five starting points#
Act as an e-commerce copywriter. Using only the product data below, write a product description of 120 to 160 words: a one-sentence opening that states what the product is and who it suits, then two short paragraphs on the features that matter most to that buyer. Do not add any specification, material, certification or measurement that is not in the data; if something useful is missing, list it under "Missing data" instead of guessing. Product data: [PASTE YOUR ATTRIBUTES: name, dimensions, materials, power, compatibility, warranty]. Target buyer: [DESCRIBE YOUR BUYER].Act as an e-commerce SEO writer. Write a product page description from the data below, working these target phrases in naturally and only where they are true of the product: [PASTE YOUR KEYWORDS]. Lead with the three details a shopper needs first, such as size, material and compatibility, and use plain text with no capital-letter emphasis, no prices, no links and no comparisons to other products. Product data: [PASTE YOUR ATTRIBUTES].Act as a brand copywriter for a premium fashion label. Write a 100-word description in our voice using the materials, construction and care details below, with concrete sensory language tied to a stated fact (for example, a named fabric or finish) instead of general praise such as "exquisite". Brand voice sample: [PASTE 2 TO 3 SENTENCES OF YOUR EXISTING COPY]. Item data: [PASTE YOUR ATTRIBUTES].Act as a merchandising editor. Turn the spec sheet below into a structured description with sections for key specifications, what is in the box, care instructions and warranty terms. Copy numbers and units exactly as written, keep the spec table in a fixed order, and mark any field the sheet leaves empty as "Not provided". Spec sheet: [PASTE YOUR SPEC SHEET].Act as a marketplace listing specialist. From the data below, draft a listing with a title, five short bullet points and a description for [NAME THE MARKETPLACE]. Then add a claims table listing every statement that is a measurable, comparative or health-related claim, and mark each as "supported by the data" or "needs evidence from me". Follow the marketplace's own listing rules, which I will paste here: [PASTE THE CURRENT STYLE RULES]. Product data: [PASTE YOUR ATTRIBUTES].What to add to any product description prompt#
- The product data itself, pasted as a labelled list or table. Google says to give a model the context "instead of assuming that the model has all of the required information", and OpenAI notes context is how you give a model data outside its training set.
- A rule for gaps. Google suggests telling the model to state that information is not available when it is not in the context; ask for a "Missing data" list instead of filled-in guesses.
- Delimiters between your instructions and your data, such as XML tags like
<product_data>. Anthropic and OpenAI both recommend tags to separate instructions, context and variable input. - One or two existing descriptions as examples of voice and length. Google recommends always including examples, but warns too many make the model overfit to them.
- The channel's rules. Google's description attribute, for example, asks for the most important details first, up to 5,000 characters, and excludes promotions, links and comparisons.
- The exact format you want back (word count, sections, plain text), since Google and Anthropic both advise stating output format and requirements directly.
A worked example#
Act as an e-commerce copywriter. Using only the product data below, write a product description of 120 to 160 words for a shopper comparing cordless drills. Do not add any specification, material, certification or measurement that is not in the data. If something a buyer would want is missing, list it under "Missing data".
<product_data>
Name: Ridgeline 18V Cordless Drill Driver, model RD-18
Chuck: 13 mm keyless, metal
Speed settings: 2 (0-450 and 0-1,700 rpm)
Battery: 18V 2.0 Ah lithium-ion, 1 included
Charger: included, 60 minute charge
Weight with battery: 1.5 kg
Warranty: 2 years
Torque: [not provided]
</product_data>
Target buyer: a homeowner doing shelves and flat-pack furniture.
A good result:
- Uses only the values in the data, with units and numbers copied exactly (13 mm, 18V, 1.5 kg, 2 years).
- Lists torque under "Missing data" instead of stating a figure.
- Contains no unsupported superlatives such as "most powerful", "longest lasting" or "professional grade".
- Leads with what the drill is and who it suits, with the key specs in the first sentences.
- Has no price, link, promotion or comparison with another brand.

Limits of this guide#
These sources establish how to give a model data and how to keep descriptions within Google's and the FTC's rules. They do not show that any prompt wording sells more, ranks higher or avoids factual errors; we tested none of the prompts. We did not fetch Amazon's listing style guidelines, so marketplace-specific rules are left for you to paste in. This is general information, not legal advice on advertising claims.

Frequently asked questions
What are the best AI prompts for product descriptions?
Paste your real product data into the prompt and tell the model to use only those attributes, so it cannot invent specs. Ask it to flag every claim you must prove, then check each one against your data sheet before publishing.
How do I stop AI inventing product specs?
Supply the specs as data and instruct the model to treat them as the only source. Google advises telling a model to state that information is not available when the context does not contain it. Add a rule to leave a field blank rather than estimate.
Can I upload AI-written descriptions to Google Merchant Center?
Yes, but Google asks for AI-generated description text to go in the structured_description attribute, with the digital source type set to trained algorithmic media. Descriptions must also avoid promotions, prices, links and comparisons, and should match your landing page.
