## Quick Answer
AI writes e-commerce product descriptions 50x faster than humans while matching or beating conversion rates — when you give it structured input (feature specs, audience, tone) and human-edit the final copy.
- Scale: 500-1,000 SKUs in a day - SEO: auto-generate meta titles + descriptions - A/B: produce 3-5 variants per product to test
## What You'll Need
- Product spec sheet (features, materials, dimensions) - Target audience definition - Brand voice guidelines - AI tool: Copy.ai, Jasper, or Claude - E-commerce platform (Shopify, WooCommerce)
## Steps
1. **Build the input template.** CSV with columns: product name, category, 5 key features, materials, dimensions, target audience, tone (luxury/casual/technical). 2. **Write the master prompt.** See below. 3. **Batch generate.** Run 10 products, review, iterate the prompt. Scale to 500. 4. **Human-edit for voice.** AI tends to be generic — inject brand personality. 5. **Auto-generate SEO metadata.** Meta title (60 chars), meta description (155 chars), alt text. 6. **Create A/B variants.** 2-3 per product to test on high-traffic SKUs. 7. **Upload via CSV or API.** Shopify / WooCommerce bulk import. 8. **Measure conversion lift.** Run 30-day test against human-written baseline.
## Master Prompt Template
``` You write conversion-optimized product descriptions for [Brand], a [brand voice] [category] company.
For the product below, write: 1. A 60-char headline 2. A 150-word description in [tone] voice 3. 5 bullet-point benefits (not features — benefits) 4. Meta title (60 chars) + meta description (155 chars) 5. 3 alt-text variants for the main image
Rules: - Lead with the customer benefit, not the product - Include the primary keyword in headline + first 50 words - End with urgency or social proof - No superlatives like "best" or "amazing" - Active voice, 8th-grade reading level
Product: - Name: {{name}} - Category: {{category}} - Features: {{features}} - Materials: {{materials}} - Target audience: {{audience}} - Price point: {{price}}
Output as JSON. ```
## Common Mistakes
- Feature lists instead of benefits — "breathable fabric" vs "stays cool on 90-degree runs" - Same copy for all products in category — zero SEO differentiation - No schema.org Product markup — miss rich snippets - Ignoring mobile — 65% of e-commerce is mobile; copy under 150 words converts better - No A/B testing — publishing and hoping

## FAQs
**Will Google penalize AI product descriptions?** No — Google cares about helpfulness and originality, not AI-origin. Generic copy (human or AI) gets penalized.
**How long should descriptions be?** 100-200 words for most SKUs. 300+ for considered purchases (furniture, electronics).
**Should I copy manufacturer descriptions?** Never — duplicate content tanks SEO. Rewrite every one.
**Can AI write in my brand voice?** Train it with 10-15 best-performing existing descriptions. Accuracy: 80%+ on second iteration.
**What about international / multi-language?** Claude and GPT-4o translate accurately. Always have a native speaker review high-value SKUs.
**How do I handle variants (size, color)?** Write one master description; vary only the differentiator.
**Conversion lift benchmark?** Well-written AI descriptions lift conversion 8-15% vs thin or generic copy (Shopify 2025 case studies).
