The Best Prompt for Product Descriptions
The best prompt for product descriptions keeps the model tied to the facts of the product. This prompt takes your spec sheet and a description of the buyer, works out the questions that buyer needs answered, and writes a title, opening, body, detail bullets and meta description around them. It adds nothing you did not supply, and it returns a fact-check table and a list of missing information so you can verify the copy before it goes live.
Product Description Prompt
Writes a title, description, detail bullets and meta description from your product facts only, with a fact-check table and a list of what is missing.

# Role You are an e-commerce copywriter. You write product descriptions that answer a shopper's questions accurately, because the page has to stand in for picking the product up in a store. # Product information Product name: [Product name] Product facts (specs, materials, dimensions, what is included, care, compatibility): [Product facts] Who buys it and why: [Who buys it and why] Brand voice: [Brand voice] Description length: [Description length] Search terms to include, if any: [Search terms to include] # Steps 1. List the three questions this customer most needs answered before buying, based on the product type and the customer description. 2. Match facts to those questions. Turn a feature into a benefit only when the facts support the link; write the benefit so the feature is still stated ("full-grain leather that develops a patina", not "luxurious feel"). 3. Write the copy: - Product title: clear and descriptive, with the product type and the one or two attributes shoppers filter by. No slogans. - Opening: one or two sentences saying what it is, who it suits and the main reason to choose it. - Body: at the requested length, in short paragraphs, ordered by the three questions. - Key details: four to six bullets, each starting with the attribute (material, size, capacity and so on) followed by the specific value. - Good to know: sizing, care, compatibility, what is not included, or who it is not right for. Leave out any line you have no facts for. - Meta description: under 155 characters, describing the product plainly. # Accuracy rules - Use only the facts supplied. Do not add materials, measurements, origins, certifications, awards, warranties, reviews or health, safety and environmental claims. - If a detail shoppers would expect is absent, do not guess. Add it to a "Missing information" list at the end. - Keep units exactly as given. - Avoid phrases that could describe any product: "high-quality", "perfect for any occasion", "takes it to the next level", "must-have". - Use each search term at most once in the title and once in the body, only where it reads naturally. Skip a term that does not fit. - Write original copy; do not echo the fact list sentence by sentence. # Output format Label each part: Title, Opening, Body, Key details, Good to know, Meta description. Then add a short "Fact check" table with two columns, claim in the copy and the supplied fact behind it, followed by the "Missing information" list. Plain text, no HTML.
Use it when you are
- Writing descriptions for new products from a supplier spec sheet
- Replacing manufacturer copy that many other stores also use
- Rewriting thin or outdated descriptions across a catalog, one product at a time
- Producing consistent copy when several people add products to the store
Why this prompt works
Shopper questions decide the order
A spec sheet lists facts in the manufacturer's order. Asking the model to name the three questions this buyer has, then arranging the copy around them, puts the deciding information first. For a commuter backpack that might be whether a laptop fits and stays dry, well ahead of the fabric denier.
Benefits stay attached to features
The instruction to keep the feature visible inside the benefit is aimed at the vague adjectives that generic prompts produce. "Roll-top closure that keeps rain out" is checkable and informative, while "superior protection" tells a shopper nothing and cannot be verified.
Invention is blocked where it does the most harm
Product copy with a wrong dimension or an unearned certification causes returns and complaints. The accuracy rules name the usual culprits, including materials, measurements, warranties and environmental claims, and the fact-check table shows where each statement came from. Checking that table takes less time than rereading the description against the spec sheet.
Gaps are reported instead of papered over
When a spec sheet omits something shoppers expect, such as weight limits or care instructions, the model lists it under Missing information. That list doubles as a request to send your supplier, and it improves the page more than polished wording would.
Search terms are handled with restraint
Limiting each term to one use in the title and one in the body, and allowing the model to skip a poor fit, keeps the copy written for people. Google's guidance on helpful content favors that approach over repeating phrases.
How to use it
- Paste the complete facts for one product: materials, dimensions with units, what is in the box, care, compatibility and available variants.
- Describe the buyer in a sentence, including the situation they are buying for.
- Add a voice note or two example descriptions from your store, and pick a length that suits your page layout.
- Run the prompt, then check the fact-check table line by line against your spec sheet before reading the copy for style.
- Fill the gaps in the Missing information list from your supplier and rerun, or add the details by hand.
- Repeat in a new message for the next product, keeping the instructions and changing only the product fields.
AI model compatibility
| Model | Status | Notes |
|---|---|---|
| ChatGPT | Expected to work | Paste two descriptions you already like as examples under the Brand voice line and ask for the same tone. Examples usually convey voice better than adjectives. |
| Claude | Expected to work | For a batch, keep the instructions fixed and paste each product's facts inside <product> tags, one product per message, so facts from one item do not leak into another. |
| Gemini | Expected to work | If the fact-check table is skipped, ask for it separately. It is the quickest way to verify the copy. |
“Expected to work” means the prompt uses plain, model-independent structure and has been reviewed for that — not that it has been run on that model. A model is marked Tested only when a test record is published below.
Worked example
Scenario: An illustrative outdoor accessories store adding a commuter backpack to its catalog.

What a good response should contain
- A title that names the product type, capacity and roll-top design without a slogan
- An opening that speaks to commuting in the rain with a laptop, followed by a body organized around fit, weather protection and carrying comfort
- Bullets that lead with the attribute and give the supplied value, such as capacity, laptop sleeve size, weight and dimensions in the original units
- No claims of being fully submersible, no warranty and no recycled-content percentage, since none were supplied
- A Missing information list raising points such as whether seams are sealed, strap adjustability and warranty terms

Limitations and things to check
- The copy is only as accurate as your spec sheet. Errors in the facts will be repeated confidently.
- The model cannot see the product or its photos, so it cannot describe look, feel or fit beyond what you tell it.
- Claims about safety, health, sustainability or regulated products may need legal review even when the facts are true.
- Marketplaces have their own title and description rules. Check the output against the requirements of each channel you sell on.
- It works one product at a time. Batches need a consistent process and spot checks.

Frequently asked questions
Can I use this to write descriptions for hundreds of products?
Yes, as a repeatable template, but run products individually or in small groups and verify each fact-check table. Mixing many products in one message raises the chance that a detail from one item appears in another. Spot-check a sample of every batch before publishing.
Will AI-written product descriptions hurt my search rankings?
Google's published guidance focuses on whether content is helpful and accurate for people, not on how it was produced. Descriptions that are specific, original and correct are in line with that guidance. Thin or duplicated copy is a problem whoever writes it.
What if my supplier gave me almost no information?
Run the prompt anyway. You will get a short description and a long Missing information list, which tells you exactly what to request from the supplier or measure yourself. Avoid filling the gaps with guesses, since wrong details lead to returns.
