Below is a practical guide plus copy‑paste prompt templates you can use (and adapt) when asking an LLM to generate or improve PrestaShop products, categories and CMS pages. The goal: predictable, SEO‑friendly, store‑ready content in the exact format you can import or paste into PrestaShop.
Quick principles
- Tell the model its role and the exact output format you need (JSON/CSV/CSV columns matching your import).
- Provide required fields and any known product data; ask it to leave unknown values blank or use placeholders (don’t let it invent SKUs, prices or stock).
- Give SEO constraints (meta title length, meta description length), URL slug rules, tone/brand voice, and target audience.
- For bulk tasks, supply the source table (CSV/JSON) or example rows and ask for an output table matching your import columns.
- Ask for alt text, schema (JSON‑LD), and short/long descriptions in separate fields.
- Request no extra commentary — only the machine‑readable output.
PrestaShop-specific tips (fields & constraints to supply)
- Product fields: name, reference/SKU, price, tax rule, wholesale_price, quantity, visibility, condition, manufacturer, supplier, short_description (HTML allowed), description (HTML), meta_title (<= 60 chars), meta_description (<= 160 chars), link_rewrite (friendly URL slug), tags, features, attributes/combinations (format?), image filenames/alt texts, ean13/upc, available_for_order, online_only, minimal_quantity, active.
- Category fields: name, description (HTML), meta_title, meta_description, link_rewrite, parent_category, thumbnail image filename, active.
- CMS page fields: title, meta_title, meta_description, link_rewrite, content (HTML), category (CMS category), indexation (noindex/nofollow).
- SEO rules: meta title ~50–60 chars, meta description ~140–160 chars, link_rewrite lowercase, hyphens, only ASCII, no spaces.
- Localization: specify language(s) (ISO code), currency if needed.
Prompt structure (recommended)
1. System / role: “You are an e‑commerce copywriter and SEO specialist who outputs machine‑readable JSON/CSV.”
2. Task: produce product/category/CMS content.
3. Inputs: product raw data (name, features, brand, keywords, audience).
4. Constraints: lengths, s, do not invent SKUs/prices, output format exactly X.
5. Example(s): show one example input → example output.
6. Final command: “Produce output now for the following items: …”
Example templates
A) Single product — JSON output (generate SEO fields, descriptions, alt text)
Prompt:
You are an e‑commerce copywriter and SEO specialist. Output only valid JSON (no explanation). For each product, return a JSON object with these keys exactly:
"name","reference","price","currency","quantity","short_description","description","meta_title","meta_description","link_rewrite","tags","image_filenames","image_alts","features"
Constraints:
- meta_title max 60 characters; meta_description max 160 characters.
- link_rewrite: lowercase, only letters/numbers and hyphens, no leading/trailing hyphen, no spaces, max 80 chars.
- short_description: 1–2 short sentences (max 160 chars).
- description: 2–4 paragraphs, HTML allowed (
,
, - , ).
- image_alts: one alt text per image, 100 chars max.
- If any required input is missing, set its value to null.
- Do not invent SKUs, prices, tax or quantities — if not provided, return null.
Now generate for the product below. Input:
name: "Aurora Ceramic Coffee Mug 350ml"
brand: "Nordic Brew"
keywords: "ceramic mug, coffee mug, dishwasher safe, nordic design"
audience: "urban professionals aged 25–45 who value minimalist Nordic homeware"
images: ["aurora1.jpg","aurora2.jpg"]
features: {"Capacity":"350 ml","Material":"Ceramic","Dishwasher safe":"Yes","Microwave safe":"Yes"}
Produce the JSON object for this product.

B) Bulk CSV generator (multiple products)
Prompt:
You are an e‑commerce SEO writer and must output only CSV rows (no headings) that match the following columns in order:
id;name;reference;price;currency;quantity;short_description;description;meta_title;meta_description;link_rewrite;tags;image_filenames;image_alts;features_json
Constraints:
- Use semicolon (;) as delimiter.
- Escape internal semicolons with \;.
- meta_title <= 60 chars; meta_description <= 160 chars.
- link_rewrite lowercase, hyphenated.
- features_json must be a JSON string with key/value pairs.
Input CSV (source) rows:
1;Solaris Insulated Water Bottle 750ml; (leave reference blank);29.99;EUR; (leave quantity blank); "vacuum insulated bottle"; "Thermo bottle with double wall insulation, keeps drinks hot/cold."; keywords: "insulated bottle, stainless steel"; images: "solar1.jpg, solar2.jpg"
2;Luna Cotton Throw 130x180cm;;49.00;EUR;20;"soft cotton throw";"Lightweight cotton throw in artisanal weave."; keywords: "throw blanket, cotton throw"; images: "luna1.jpg"
Produce two CSV rows (one per product) matching the output columns. Do not output anything else.

C) Category description
Prompt:
You are a content strategist and SEO writer targeting the keyword "men's waterproof jackets." Output only a JSON object with keys: "name","link_rewrite","meta_title","meta_description","description". Constraints:
- meta_title <= 60 chars, include primary keyword.
- meta_description <= 160 chars, include main benefits and a call to action.
- description: 1 short intro paragraph + a bulleted list of 5 benefits/features (use HTML
- ).
Input:
name: "Men's Waterproof Jackets"
audience: "outdoor enthusiasts and city commuters who need breathable and durable outerwear"
brand_voice: "practical, confident, outdoorsy"
Produce the JSON.
---
D) CMS page (About Us)
Prompt:
You are an e‑commerce copywriter. Output only JSON: keys: "title","meta_title","meta_description","link_rewrite","content_html". Constraints:
- content_html should be three short sections with headings (
) and 2–3 sentences each; include brand story, sustainability, and shipping/policies summary.
- meta_title <= 60 chars.
- meta_description <= 160 chars.
Input:
title: "About Nordic Brew"
brand_tone: "friendly, minimalist"
founding_year: 2016
mission: "functional, sustainable homeware inspired by Scandinavian design"
Produce the JSON.
---
E) Multilingual output (example)
Prompt:
You need content in two languages. Output JSON with keys "lang","name","short_description","description","meta_title","meta_description","link_rewrite". Provide two objects in an array: one for en, one for fr. Respect locale punctuation and idiom.
Input:
name_en: "Aurora Ceramic Coffee Mug 350ml"
keywords_en: "ceramic mug, coffee mug"
name_fr: "Tasse en céramique Aurora 350ml"
keywords_fr: "tasse en céramique, tasse à café"
Produce the array.
Practical examples of short commands you can reuse
- “Write three SEO title variants (<=60 chars) and three meta descriptions (<=160 chars) for [product]. Return JSON with arrays title_variants and meta_variants.”
- “Generate 5 alt texts for images [file1,file2] matching the product: [short product input]. Return JSON array.”
- “Rewrite the product short_description in a more persuasive tone (1 sentence, max 140 chars).”
Avoid hallucinations and bad defaults
- Tell the model not to invent: “Do not add prices, SKUs, EANs or stock unless I supply them.”
- For facts (materials, certifications), ask to mark as "to verify" or return null if uncertain.
Validation & testing checklist
- Import a few generated rows into a staging PrestaShop and check: slug formatting, character truncation of meta tags, HTML safety (no scripts), image filename matches actual uploads.
- Check language accuracy for localization.
- Run SEO checks (title uniqueness, meta duplicates).
- Confirm alt texts are descriptive and unique.
Iterate and refine
- Provide feedback examples (e.g., “Make tone friendlier and reduce jargon”).
- Use few‑shot examples to lock format.
- When results vary, pin the exact character counts and formatting rules again.
Short sample prompt you can copy/paste (product CSV bulk)
You are an e‑commerce SEO writer. Output only CSV rows (semicolon separated) matching columns:

Constraints:
- meta_title <= 60 chars, meta_description <= 160 chars.
- link_rewrite: lowercase, hyphens, ascii only.
- If a value is unknown, output an empty field.
- Do not include any extra text or explanation.
Now process the following input rows:
[Paste your source rows here]
— end —
If you want, paste one or more real product/category/CMS rows (or a CSV snippet) and I’ll produce a ready‑to‑import JSON/CSV example using the templates above.
