AI Prompt for Short Product Descriptions
Short product description generator: Sometimes 100 words outsell 400. Includes a worked example with filled variables. No prompt engineering needed.
The prompt
You are a minimalist copywriter. You believe every word must earn its place, and you cut ruthlessly. Context: [STORE_NAME] sells [PRODUCT] for [PRICE] to [TARGET_CUSTOMER]. The 3 things a buyer must know: [MUST_KNOW_1], [MUST_KNOW_2], [MUST_KNOW_3]. Keyword: [KEYWORD]. Task: Write a product description of 80-120 words maximum. Structure: one hook sentence, 3 bullet points (the must-knows, phrased as benefits), one closing line with a soft call to action. Constraints: - Hard cap: 120 words. If a sentence doesn't help a buyer decide, delete it. - Use [KEYWORD] once, naturally, in the first two sentences. - Bullets under 15 words each. - No backstory, no brand mission, no filler adjectives. - Plain everyday English. Must be fully scannable in 10 seconds. Constraints continued: the hook sentence must contain the single most reassuring fact about this product - the thing that removes the biggest doubt. Never open with brand history or mission statements; the buyer's doubt comes first. If the product has variants, add one line directing shoppers to the variant picker instead of describing every option.
Variables to fill in
Replace each [variable] in the prompt with your own details:
[STORE_NAME] [PRODUCT] [PRICE] [TARGET_CUSTOMER] [MUST_KNOW_1] [MUST_KNOW_2] [MUST_KNOW_3] [KEYWORD]
Example input
STORE_NAME: DailyDose | PRODUCT: vitamin D3 gummies | PRICE: $14 | TARGET_CUSTOMER: busy adults | MUST_KNOW_1: 2000 IU per serving, 60 gummies | MUST_KNOW_2: no gelatin, vegan | MUST_KNOW_3: third-party tested | KEYWORD: vitamin D3 gummies
How to use this prompt
Use short descriptions for low-consideration products under ~$25, add-on items, and variants (colors/sizes) where the main product page already does the heavy selling.
Tips for the best results
- Write the 120-word version first, then cut 20% - the second draft is always the one that converts.
- Front-load the price justification: the most reassuring fact goes in the hook sentence.
- Pair short descriptions with strong images; words do less work when photos do more.
Frequently asked questions
When is a short description better than a long one?
For repeat purchases, low prices, and simple products where shoppers decide in seconds. Complex or expensive products need the long version.
Does a short description hurt SEO?
Slightly, for competitive keywords. Compensate with keyword-rich titles, image alt text, and FAQ schema on the page.
