What is the ADEO Marketplace?

The ADEO Marketplace is a unified B2C and B2B platform launched progressively since 2017 (starting with Leroy Merlin Brazil) and accelerated in Europe during the COVID-19 pandemic, with key rollouts in France (2020), Italy and South Africa (2021), Spain (2022), and Portugal (2023). Poland follows in 2025.[1] It integrates third-party sellers into ADEO's e-commerce sites and apps, extending product ranges in home improvement without heavy inventory investments.

Sellers gain access to high-traffic sites like Leroy Merlin, with strict standards for quality, compliance, and sustainability (e.g., FSC/PEFC for wood products).[1]

Sellers must have a European HQ, sign the Responsible Purchasing Code, and meet quality thresholds. Nearly 5,000 partners benefit from data tools, fulfillment options, and omnichannel integration.[2]

Essential Product Data Specifications

ADEO (via Mirakl/Leroy Merlin) demands structured feeds. Suppliers upload CSVs with titles/descriptions to PIM for AI enhancement (e.g., Google Gemini generates full listings).[5]

| Field | Requirement | Notes | |-------|-------------|-------| | EAN/GTIN | Mandatory (13-digit) | Unique identifier; matches offers/images.[6] | | Brand | Mandatory | Prominent in title; use exact match. | | Title | Max 120 chars, per language | Brand + key features (color, size, material). | | Description | Max 5,000 chars, HTML | Long desc per country; bullet benefits. | | Images | 500x500px min, up to 10 URLs | No text; first image primary. | | Price | EUR/PLN | Include VAT attrs per channel. | | Logistics | Class codes (e.g., XXXS for <5kg) | Dimensions/weight limits. |

Key Takeaway: Aim for 55%+ completeness: 9 images, important/positive impact attributes filled. Contact your Account Manager for scores.[7]

Crafting SEO-Optimized Product Titles

Titles drive 80% of clicks. For ADEO, keep under 120 characters: [Brand] [Key Feature] [Size/Color] [Material] – e.g., "Bosch Drill 18V Cordless Lithium-Ion Battery Green 1.5Ah".

Actionable Tips:

1. Front-load keywords from buyer searches (e.g., "solar panels FSC certified").
2. Multilingual: FR "Perceuse Bosch 18V Sans Fil", ES "Taladro Bosch 18V Inalámbrico".
3. Avoid fluff; test variations.

Tools like Optivise generate titles from ASINs/search data, boosting relevance.[4]

Writing High-Converting Descriptions

Short summary + long HTML-rich desc. Use Gemini-inspired structure: features, benefits, specs, FAQs.

Best Practices:

• Bullets for scannability: "• Durable steel build • 2-year warranty".
• Buyer pain points: "Perfect for DIY renovations without professional tools".
• Sustainability: Highlight FSC/PEFC, energy labels.
