Below is a practical, copy‑pasteable guide with ready-made prompt templates and examples you can use to generate high-quality product pages, category pages, and CMS pages for PrestaShop using an LLM (ChatGPT or similar). It covers prompt structure, required fields, output formats (JSON for easy import), SEO, multilingual output, tone/s, constraints, and tips for iterative improvement.
1) Prompt structure (the “perfect” prompt)
Always include these parts in this order:
- Role: what the model should act as (e.g., “You are an eCommerce copywriter and SEO specialist”).
- Goal: what you want produced (e.g., “Create product title, SEO meta, short & long descriptions, bullets, attributes, and JSON output for PrestaShop”).
- Context / inputs: product specifics (name, brand, SKU, features, materials, use cases, target audience, keywords, images if any).
- Constraints & format: word counts, allowed HTML tags, JSON schema, language, tone, number of variants.
- Examples (optional but powerful): show 1 example input→output to lock format.
- Output only: instruct to return only the requested JSON/format, no commentary.
2) Generic JSON schema for PrestaShop product output
Use this schema to make outputs importable or to paste into PrestaShop Manager:
{
"name": "string",
"reference": "string", // SKU
"price": "string or number",
"meta_title": "string",
"meta_description": "string",
"link_rewrite": "string", // URL slug
"description_short": "string", // HTML allowed
"description": "string", // HTML allowed (full product description)
"features": [ {"name":"", "value":""} ],
"attributes": [ {"group":"", "name":""} ],
"tags": ["tag1","tag2"],
"images": ["image1.jpg","image2.jpg"], // optional names
"ean13": "string",

}
3) Ready-to-use master prompt (product)
Copy, paste and replace placeholders in brackets:

7) Multilingual output
Add: "Return the output in [LANGUAGE]. Translate any technical terms accurately. Keep meta fields within character limits for that language."
Or request bilingual JSON:
"Also include 'meta_title_es' and 'meta_description_es' with Spanish translations."
8) Examples (realistic product output snippet)
Minimal example to show the format:
Input:

"
- description: "The Nomad Leather Wallet is crafted from full-grain leather...
Buy now.
"
9) Tips for improving prompts and working at scale
- Provide a strong role and clear constraints (character limits, HTML) so the model knows the format.
- Always request a strict JSON or CSV formatted output for programmatic import.
- Give 1 example input→output to lock s/format.
- Produce multiple variants at once (e.g., "Give 3 meta_description variants") so you can A/B test.
- Use chain-of-thought avoidance: include “Do not explain steps; return only the JSON” to prevent extra text.
- Validate outputs: check meta lengths, slug formatting, presence of keywords.
- Use temperature=0–0.3 for consistent outputs; higher temperature for creative taglines.
- For bulk, prepare a CSV with columns for the product fields and a generic prompt that references each row; use an automation script to call the LLM per row.
10) SEO & legal cautions
- Keep claims accurate (e.g., “sustainable” only if certified); avoid medical/legal guarantees unless validated.
- Ensure keywords are used naturally; avoid keyword stuffing.
- Localize measurements, currency, and shipping details for target markets.
11) Quick cheatsheet of prompt options
- "Give me 3 tone variants" — add field "tone_variants": ["friendly","technical","luxury"] and produce versions.
- "Create 5 short product taglines" — returns array of 5 strings.
- "Produce JSON and a CSV-ready single line" — include a "csv_line" field with comma-separated values.
12) Example full prompt you can paste and reuse (product)
You are an expert eCommerce copywriter and SEO specialist. Given the product details below, output only JSON that exactly matches this schema: {paste the product JSON schema}. No additional commentary.

Rules:
- meta_title ≤ 60 chars; include 'travel mug'.

- link_rewrite: lowercase hyphen slug with main keyword.

Now generate the JSON.
13) Final tips for success
- Start with a handful of high-quality product prompts and iterate: refining one product’s prompt will improve outputs for the whole catalog.
- Automate validation: script character counts, slug checks, and forbidden-words checks.
- Keep prompts up to date with PrestaShop fields you actually use (some shops use custom attributes).
If you want, I can:
- Convert several real product rows (paste 3–5 product inputs) into ready-to-import JSON.
- Create CSV templates for bulk import into PrestaShop Manager.
- Produce category and CMS example pages for a specific store — paste sample inputs and I’ll generate them.
