Prompt: Write Product Descriptions That Sell

Product descriptions on most websites read like spec sheets. "Made from premium materials. Available in three colors. Dimensions: 12x8x4." That tells buyers what the product is. It does not tell them why they should care.

This prompt generates descriptions that sell because they focus on what changes for the buyer. Use it to prompt write product descriptions that sell by connecting features to real outcomes.

The Prompt

Write a product description for the following:

PRODUCT: [Name and what it is]
PRICE POINT: [Price range - this affects the tone and justification needed]
TARGET BUYER: [Who buys this and what situation are they in when they search for it]
TOP 3 FEATURES: [The features that matter most]
KEY DIFFERENTIATOR: [What makes this different from the obvious alternatives]
BRAND VOICE: [e.g., "Premium and understated" or "Fun and energetic" or "Technical and precise"]

Write the description in this structure:
1. OPENING LINE: One sentence that describes the outcome, not the product. What does life look like after buying this?
2. THE PROBLEM: What frustration or need drove them to search for this? (2 sentences max)
3. THE SOLUTION: How this product solves that problem. Connect each feature to a benefit. (3-4 bullet points using the format: [Feature] so you can [benefit])
4. THE DIFFERENTIATOR: Why this one instead of the alternatives. (1-2 sentences)
5. SOCIAL PROOF: [Include if provided, otherwise skip]
6. CTA: Direct action with urgency if appropriate

Rules:
- Total length: 100-200 words
- Grade 5 reading level. Short sentences. No jargon.
- No "whether you are a beginner or expert" cliches
- No "in today's world" or "look no further" filler
- Every sentence must earn its place. If it does not sell, cut it.
- Features without benefits are banned. Always connect to what the buyer gets.

Adapting by Price Point

Products under $50 need quick, punchy descriptions. Impulse territory. Keep it to 100 words.

Products from $50 to $500 need more justification. Add social proof, comparison to alternatives, and a stronger differentiator section. 150 to 200 words.

Products over $500 need trust-building. Detailed benefits, warranty information, guarantee language, and multiple social proof points. The prompt scales with the price.

Batch Generation

For ecommerce stores with dozens of products, run this prompt in a loop. Create a spreadsheet with the inputs for each product, then feed them to Claude one by one. You can generate 50 product descriptions in an hour that would take a copywriter a full week.

Review each one. The AI gets the structure right. You add the brand-specific nuance that makes it yours.

Testing What Works

A/B test descriptions on your top-selling products. Measure conversion rate, not just traffic. A description that sells 20% more units is worth more than one that ranks slightly higher in search.
