Claude Prompt for Writing Product Descriptions
Writing product descriptions is a strategic exercise combining commercial persuasion, SEO optimization, and technical precision. Each description must convince a potential buyer in seconds while meeting search engine requirements. Claude excels at this task thanks to its ability to structure information hierarchically, adapt tone according to the target, and produce content that is both engaging and factual. Whether you manage a catalog of 50 or 5,000 references, Claude allows you to maintain editorial consistency while personalizing each description according to product specifics. The AI understands e-commerce copywriting mechanics: benefits before features, objection handling, calls to action, and scannable structuring. By providing Claude with the right product information and your brand context, you get publish-ready descriptions that turn visitors into buyers. This guide offers tested and optimized prompts to get the most out of Claude for writing your product descriptions, regardless of your industry.
Paste in your AI
Paste this prompt in ChatGPT, Claude or Gemini and customize the variables in brackets.
You are an expert e-commerce copywriter specializing in high-conversion product descriptions. Write a complete product description for the following product:
Product: [PRODUCT_NAME]
Category: [CATEGORY]
Price: [PRICE]
Target audience: [Describe your ideal customer]
Technical specifications: [List main specs]
Competitive advantages: [What sets this product apart]
Brand tone: [E.g., premium, accessible, technical, lifestyle]
Structure your description as follows:
- Catchy title — incorporate the main benefit and target keyword
- Subtitle — one sentence that creates desire
- Short description (2-3 sentences) — the pitch that makes them want to read more
- Key benefits (3-5 bullet points) — each point starts with an action verb and highlights a customer benefit, not a technical feature
- Long description (150-200 words) — usage-oriented storytelling, naturally integrate SEO keywords
- Technical specifications — clear and scannable table
- Product FAQ (3 questions) — address common purchase objections
- Meta title (max 60 characters) and meta description (max 155 characters) for SEO
Style guidelines:
- Use the formal "you" (vous)
- Prioritize short, punchy sentences
- Avoid jargon unless the audience is expert
- Every sentence must justify its presence: if it doesn't inform or persuade, remove it

Why this prompt works
This prompt works because it gives Claude a precise role (e-commerce copywriter), a detailed output structure, and clear style constraints. The variables in brackets allow contextualizing each generation with specific product data. The explicit separation between benefits and features forces the AI to adopt a customer-oriented rather than technical approach.

Frequently Asked Questions
How do you tailor a prompt for a catalogue of hundreds of products?
Build a prompt template with standardized variables (name, category, specs, USP), then feed it to Claude product by product via the API or in batches within a conversation. Set a style guide at the start of the conversation to keep things consistent: tone, target length, structure, and forbidden words. Claude retains context and will apply the same rules to every product listing. For very large catalogues, use the Claude API with a script that injects product data from your PIM or spreadsheet.
Can Claude write SEO-optimized product descriptions without cannibalizing my other pages?
Yes, as long as you provide the primary keyword AND the keywords already targeted by your other pages. Include this in your prompt: "The primary keyword is [X]. Do not target [Y] and [Z], which are already covered on other pages." Claude will adapt the semantic field accordingly. For best results, also provide your site's semantic cocoon or category structure so each description reinforces the pillar page rather than competing with it.
How can I ensure the descriptions generated by Claude don't sound like generic AI content?
Three essential levers: first, provide samples of existing descriptions from your brand so Claude captures your voice. Second, include specific, tangible details in your specifications (not "quality materials" but "brushed 316L stainless steel"). Third, ask Claude to incorporate social proof or real-world usage elements: "Include a concrete usage scenario for each benefit." Generic content always comes from a generic prompt — the more precise your brief, the more unique and authentic the description will be.
