Below is a concise, practical guide and ready-to-copy prompt templates you can use to generate product content, category descriptions, and CMS pages for PrestaShop with ChatGPT or other LLMs. Use the templates as-is or adapt to your brand, locale and product data.
Short checklist (best practices)
- Specify role and goal (e.g., “You are an e-commerce copywriter for a premium electronics store”).
- Provide context: brand voice, audience, s, language and locale (en-US, fr-FR), and examples.
- State exact deliverables and format (CSV, JSON, HTML, or PrestaShop column names).
- Give constraints: character limits (meta title < 60 chars, meta description < 160 chars), allowed HTML for long descriptions, slug format, measurement units, currency.
- Include SEO keywords to use and forbidden words.
- Request multiple variations and quality checks (tone variants, short/long).
- Use temperature=0 for deterministic output when importing at scale.
- Test with a few products before bulk generation.
Prompt structure to follow
1. System/role: define the persona and task.
2. Context: brand info, audience, SEO keywords, locale.
3. Input: raw product data or CSV columns to fill.
4. Output requirements: exact fields, format (JSON/CSV), HTML allowed, character limits.
5. Example: show one filled example (few-shot).
6. Constraints: avoid banned words, keep consistent formatting.
7. Follow-ups: ask to generate variations, alt text, JSON-LD, or CSV-ready rows.

Return only JSON: {"title":"", "content_html":"", "meta_title":"", "meta_description":"", "slug":""}
5) Product variants and SKU generator
Prompt:
You are an e-commerce SKU and variant generator. Given base product "Classic Tee" with attributes: Color [White, Black, Navy], Size [S, M, L], base SKU "CT-BASE", base price 19.99 USD. Generate all variant rows in CSV with columns:
"SKU","Variant name","Attribute combination","Price","Quantity","Reference","Friendly URL"
Rules:
- SKU format: BASE-XX where XX encodes color code and size (e.g., CT-BASE-WHT-S).

8) Image alt and social copy
Prompt:
For product "[product name]" with images [list], generate:
- One alt text per image (short, 8–15 words).
- 3 social posts: Twitter (max 280 chars), Instagram caption (max 2200 chars with hashtags), Facebook post (short).
Return JSON.
Examples: small sample output (single product)
{"name":"Aurora Ceramic Mug","short_description":"Handmade 350 ml ceramic mug — matte finish, dishwasher-safe.","description":"Handmade 350 ml ceramic mug with a soft matte finish. Dishwasher and microwave safe. Ideal for everyday use or gifting.
- Capacity: 350 ml
- Material: Stoneware
- Care: Dishwasher safe
","meta_title":"Aurora Ceramic Mug — Handmade 350ml","meta_description":"Handmade 350ml ceramic mug with a matte finish. Dishwasher safe and perfect as a gift.","friendly_url":"aurora-ceramic-mug","tags":["ceramic mug","handmade mug","dishwasher safe"],"categories":["Home > Drinkware"],"price":"12.99","quantity":120,"reference":"AUR-MUG-350","images":["aurora-1.jpg","aurora-2.jpg"],"image_alts":["Aurora ceramic mug matte finish","Aurora mug on wooden table"],"technical_specifications":[{"key":"Capacity","value":"350 ml"},{"key":"Material","value":"Stoneware"}]}
Practical tips for reliable bulk import
- Start with 10–50 products to validate formatting and mapping.
- Export sample PrestaShop import CSV to match exact column headers and accepted value formats.
- Use UTF-8 encoding, no BOM.
- If long_description contains HTML, ensure it’s allowed on your PrestaShop fields and properly escaped.
- Sanitize friendly URLs: remove accents or request the LLM to transliterate.
- Validate generated EAN/UPC formats when required.
Prompt tuning & workflow ideas
- Use a system role message: “You are an expert e‑commerce copywriter specialized in PrestaShop product data.” Keep temperature low for repeatability.
- Few-shot: give 1–2 perfect examples for s and field population.
- Iterative pipeline: (1) generate base content, (2) run SEO/meta rewrite, (3) generate alt tags & social copy, (4) compile CSV/JSON for import.
- Automate checks: character counters and slug validators before bulk import.
Common pitfalls to avoid
- Vague prompts (no brand voice or audience).
- Not specifying output format → messy text instead of CSV/JSON.
- Not giving constraints (meta title too long, HTML injection).
- Asking for too many unrelated deliverables in one prompt — split tasks.
If you want, paste a sample product or the exact PrestaShop CSV columns you use and I’ll generate a copy-ready prompt and example output tailored to your store.
