How to Write Product Descriptions With Claude

By Savora Finance · Reviewed 2026-11-08

A practical method with prompts you can copy, plus the checks that keep an AI-written description accurate and honest.

Why descriptions are worth the effort

A product page has to do the job of a shop assistant. It must tell the shopper what the item is, who it suits, how big it is and what happens if it does not work out. Photos get attention, but the words answer the questions that stop people from buying. Many new store owners find writing the hardest part. An AI assistant such as Claude is useful here because it removes the blank page. It still needs your facts to work from.

Start with facts, not with the prompt

The quality of the result depends on what you give it. Before you ask for anything, write down the real details in plain notes: what the product is, its size and weight, the materials, colors, how it is made, how to care for it, who it is for and what makes it different. If you leave a detail out, the assistant may invent one that sounds plausible, and an invented detail on a product page can mislead a customer.

A prompt you can copy

Paste your notes under this instruction and fill in the brackets:

Write a product description for my online store.

Product: [name]
Facts (use only these, do not add details): [your notes]
Customer: [who buys it and why]
Tone: [warm / plain / playful]
Length: about 120 words, then 4 short bullet points covering size, materials, care and shipping.
Do not use words like "perfect", "amazing" or "best". Do not make health, safety or performance claims.
If something important is missing from my facts, list it at the end as a question.

The last line matters. It makes the assistant tell you what it needs instead of guessing, and the answers often point to gaps in your product page.

Prompts for the other text in your store

Product titles: "Suggest five clear titles for this product, each under 60 characters, using the words a shopper would search for."
Collection pages: "Write a 60-word introduction for a collection called [name] that contains [list of products]."
FAQ section: "List ten questions a first-time buyer of this product would ask, and draft short answers using only the facts I gave you."
Email to customers: "Write a short, friendly email to someone who just bought [product], confirming the order and setting expectations for shipping."

A checklist before you publish

Facts. Compare every number, material and claim against your notes.
Promises. Remove anything you cannot guarantee, such as "lasts forever" or "works for everyone."
Regulated claims. Delete health, safety, medical or environmental claims unless you can support them and know the rules for your product.
Voice. Read it aloud. If it does not sound like you, edit until it does.
Originality. Make sure descriptions differ between products. Near-identical pages help neither shoppers nor search engines.

Mistakes to avoid

Publishing the first draft without reading it carefully.
Accepting vague filler such as "high-quality" when a specific detail would convince better.
Letting the assistant invent reviews, testimonials or statistics. Never publish those.
Pasting customers' names or addresses into an AI tool when you do not need to.

A before-and-after example

Before (your notes): hand-poured soy candle, 8 oz glass jar, cotton wick, about 45 hours, scents: cedar and orange, made in small batches in my kitchen.

After (a good first draft you would then check): "A small-batch soy candle, hand-poured in an 8 oz glass jar with a cotton wick. Cedar and orange give it a warm, woody scent that fills a room without overwhelming it. Burns for about 45 hours." Notice that it adds nothing you did not provide. If your draft contains a claim that is not in your notes, that is the thing to remove.

Frequently asked questions

Will search engines penalise AI-written text?

Search engines have said they care about whether content is helpful and accurate, not about how it was produced. Pages that are thin, repetitive or misleading do poorly whoever wrote them. Add your own facts and check the result.

How long should a product description be?

Long enough to answer a buyer's questions. For simple products, 80 to 150 words plus a short list of details is usually plenty.

Can Claude write the whole store for me?

It can draft text and plan the structure. You still need to choose the product, set the price, take the photos and check everything before it goes live. See our seven-step plan.
