Product description prompts for ecommerce

These 14 product description prompts turn your product data into ecommerce copy with ChatGPT, Claude or Gemini: descriptions from a spec sheet, short and long versions, bullets, consistent copy across a catalog and its variants, Google Shopping titles, and claim checks before you publish. Each prompt works from facts you supply, because a product description with an invented spec is worse than none.

How to use these prompts

Replace the blanks in double braces, or keep the default after the colon: {{product:a stainless steel water bottle}} means that product unless you change it.

Gather the inputs first: the spec sheet or product data export, photos you can describe, who buys it and why, the top questions from support or reviews, and your return reasons if you track them. Paste real data into the prompts rather than describing it from memory.

Tell the model what it may not do. Every prompt below says to use only the facts given and to mark gaps instead of filling them. Anthropic's guide to reducing hallucinations recommends giving the model explicit permission to admit uncertainty, which is exactly what you want when a spec is missing.

These prompts focus on individual product pages. For headlines, landing pages and offers, use the copywriting prompts.

Which prompts write a product description?

1. Description from a spec sheet

The starting point for most products: facts in, readable copy out.

Write a product description for {{product:a stainless steel water bottle}} using only the facts below.

Spec sheet:
{{specs}}

Who buys it: {{buyer:commuters and gym-goers}}
Brand voice: {{voice:plain, friendly, no hype}}

Structure: one opening sentence on what it is and who it's for, a short
paragraph on the main benefit, then the key specs as a short list. Turn
each spec into what it means for the buyer ("holds 750 ml, enough for a
long workout"). If a benefit needs a fact I didn't give, write
[NEED: fact] instead of guessing.

2. Write for one specific buyer

The same product reads differently to a parent, a professional and a gift buyer.

Here is a product description:

{{description}}

Rewrite it for this buyer: {{buyer:a parent buying for a 10 year old}}.
Their main worry: {{worry:will it break or leak in a school bag}}.

Lead with what answers the worry, keep every fact identical, and drop
details this buyer won't care about. Under {{words:120}} words.

3. Short and long versions

Product pages, category grids, marketplaces and emails all need different lengths.

From this product data, write:
1. A one-line summary under 120 characters for category pages.
2. A short description of about 50 words for above the fold.
3. A full description of {{words:200}} to 300 words with subheadings for
   materials, use, care and what's in the box.

Product data:
{{product_data}}

All three must agree on every fact. Use only the data given.

4. Feature bullets that answer questions

Bullets are where many shoppers decide. Make each one carry a fact and a reason.

Write {{count:5}} bullet points for {{product}}.

Facts: {{specs}}
Top customer questions: {{questions}}

Each bullet starts with a short bolded label, then one sentence that
pairs a specific fact with why it matters. Cover the questions above
first. No vague words like "premium" or "high quality" unless a fact
right next to them supports it.

Which prompts handle catalogs and variants?

5. A template for a whole product line

Consistency makes a catalog easier to shop and easier to maintain.

Here are descriptions for {{count:3}} products in our {{line:kitchen knives}} line:

{{descriptions}}

Design a description template for this line: section order, what each
section must contain, length per section, and words to always or never
use. Then rewrite the 3 descriptions to fit the template, keeping every
fact. Flag facts that one product has and the others are missing.

6. Variant descriptions without duplicate copy

Colors, sizes and bundles need their own details, not the same paragraph pasted again.

Base product description:
{{base_description}}

Variants:
{{variants:Small 500 ml, Medium 750 ml, Large 1 litre}}

For each variant, write 2 or 3 sentences covering only what differs
(size, weight, best use) and who it suits best. Keep the base
description unchanged. Finish with a short comparison table of the
variants using only the data given.

7. Rewrite supplier copy

Manufacturer text is often generic, oddly translated, and identical to every other seller's page.

Here is the supplier's description for {{product}}:

{{supplier_copy}}

Rewrite it in our voice ({{voice:plain, friendly, no hype}}) for
{{buyer:home cooks}}. Keep every factual spec, remove claims we can't
verify ourselves, and list those removed claims separately so I can
check them with the supplier. Don't add any new facts.

8. Fill the gaps that cause returns

Return reasons and support tickets show what the description failed to say.

Here is our product description and a list of return reasons and
customer questions for {{product}} from the last {{period:90 days}}:

Description:
{{description}}

Return reasons and questions:
{{returns_and_questions}}

Group the reasons into themes and count them. For each theme, say
whether better description content could have prevented it (sizing,
color accuracy, compatibility, what's included). Draft the exact
sentences to add, using only facts from my data, and mark any fact I
still need to supply.

Which prompts write for search and shopping feeds?

9. Google Shopping title and description

Google Merchant Center's title spec allows 1 to 150 characters and says to put the most important details first. Its description spec allows up to 5,000 characters and says not to include promotional text such as price, sale price, sale dates or shipping.

Write a Google Merchant Center title and description for this product.

Product data: {{product_data}}
Variant: {{variant:Medium, 750 ml, matte black}}

Title: under 150 characters, most important details first (brand,
product type, key attribute, variant details). No price, shipping,
promotional words, all caps or symbols.

Description: put the key details in the first 160 characters, then
materials, dimensions, features and care. No comparisons with other
brands, no links, no promotional text. Show the character count for
both.

10. Page title and meta description

For your own product page in search results. Keep it accurate to the page.

Write {{count:3}} options each for an HTML title tag (under 60
characters) and a meta description (under 155 characters) for this
product page.

Product: {{product}}
Main search phrase: {{keyword:insulated water bottle 750ml}}
What makes it different, with proof: {{differentiator}}

Put the search phrase near the start of the title. The meta
description should say what it is, one concrete reason to choose it,
and nothing the page doesn't support.

11. Product FAQ from real questions

Answers the questions shoppers ask before they buy, in their words.

Here are customer questions about {{product}} from {{sources:support tickets, chat logs and product reviews}}:

{{questions}}

Product facts:
{{facts}}

Group duplicate questions, pick the {{count:6}} most common, and write
a short answer to each using only the product facts. If a question
can't be answered from the facts, list it separately so I can find the
answer. Don't invent customer quotes or reviews.

Which prompts check claims before you publish?

12. Claim check against the evidence

The FTC's advertising guide for small business says "An implied claim is one made indirectly or by inference," and both kinds need proof.

Review this product description as a careful compliance editor for a
store selling in {{market:the United States}}.

{{description}}

Evidence we have:
{{evidence}}

List every claim, including implied ones (for example, "lab tested"
implying a specific result). For each, give: the claim, express or
implied, the evidence that supports it from my list or "none", and a
safer rewrite if the evidence is missing. Flag health, safety, and
"best" or "#1" claims for extra review. This is a first pass, not legal
advice.

13. Environmental claims check

The FTC's summary of the Green Guides says "Marketers should not make broad, unqualified general environmental benefit claims like 'green' or 'eco-friendly.'"

Check these environmental claims in our product copy:

{{claims}}

Facts we can prove: {{proof:packaging is 80 percent recycled cardboard}}

For each claim: is it a general claim like "eco-friendly" or
"sustainable" that should be replaced with a specific one? Does it need
a qualifier (for example, recyclable only where facilities exist)? Is
it supported by the facts above? Rewrite each into a specific, provable
statement, or recommend removing it.

14. Country of origin wording

The FTC's Made in USA guidance says an unqualified claim means the product is "all or virtually all" made in the United States.

Here is how our product is made:

Where it is assembled: {{assembly}}
Where the main components come from: {{components}}
Our current origin wording: {{current_wording:Made in USA}}

Explain whether our wording fits the facts, and suggest accurate
alternatives (for example, "Assembled in USA" or "Made in USA from
imported parts") with the facts each one depends on. Point out anything
I should confirm with a lawyer.

What does the FTC say about claims in product descriptions?

If you sell in the United States, a product page is advertising, and the FTC's rules apply whether a person or a model wrote it. Its small business guide says "Advertising must be truthful and non-deceptive," advertisers "must have evidence to back up their claims," and for health or safety claims the standard is generally "competent and reliable scientific evidence."

The FTC's Consumer Reviews and Testimonials Rule Q&A covers reviews in detail. This page is a summary, not legal advice. For health, safety, children's products or anything regulated, talk to a lawyer.

How do you keep AI product descriptions accurate?

Feed it structured data. A spec sheet or product export beats a description from memory. Paste it as a list or table so each fact is easy to check.

Ask for gaps, not guesses. Every prompt above uses a marker like [NEED: fact]. Search the output for it before publishing.

Compare against the source. After the model writes, run a quick check: "List every number, material and dimension in this description and the line in my spec sheet it came from." Anything without a source line comes out.

Watch the adjectives. "Premium", "durable" and "best" are where unsupported claims hide. Replace them with the fact that earns them, or cut them.

Keep your product description prompts in one place

If you write descriptions every time new stock arrives, save prompt 1 and your line template from prompt 5 once and reuse them. Kipt keeps prompts as Markdown in a private GitHub repo you own, with their blanks ready to fill; tag them by stage (write, feed, check) and press ⌘K to find one. To make your description rules a reusable skill for Claude or Codex, paste them into the free SKILL.md generator. For search work beyond product pages, see the SEO prompts.
