Winning 3P Marketplaces: How iO Built a Profitable Multi-Market Retail Media Strategy for Versuni Across 7 European Marketplaces

The Challenge

Versuni needed a unified third-party (3P) retail media strategy across 7 different e-commerce marketplaces in 5 European countries, each with distinct platform algorithms and bidding rules.

The Strategy

Implement a localised execution framework tailored to category dynamics and platform-specific bidding logic.

Execution and Innovation

Managed advertising across 4 languages on 7 platforms, continuously reallocating budget toward high-performing product categories.

Results

Generated €2,122,080 in turnover from €284,164 in spend (blended 7.47 ROAS), improved ad efficiency by 17.8%, and turned underperforming channels like Cdiscount into top performers.

Judges' Verdict

"Knowing your disadvantage and build around it is impressive. That takes courage. That's what 'localise, don't translate' does here, and I really liked it."
