How Netshoes Increased ROAS by 72% with GenAI-Powered Catalog Product Video

With a significant share of products coming from 3P sellers, Netshoes faced a challenge: inconsistent product image quality across their catalog.

Low-quality or mismatched images were negatively affecting ad engagement and limiting the performance of their catalog-based campaigns. This inconsistency created friction in the customer journey, reducing both conversion rate and return on ad spend (ROAS).

Netshoes partnered with ROI Hunter with the goal of:

• Improving the visual quality of product ads
• Enhancing the consistency of catalog creatives across categories
• Driving measurable improvements in conversion rate, transactions, and ROAS

Building on the proven success of Catalog Product Video (CPV), Netshoes took their creative strategy a step further by adopting ROI Hunter’s new GenAI technology.

1. Image Enhancement with GenAI

• Background removal to eliminate distracting elements

• AI-generated scenes and settings to place products in visually appealing environments

• • AI product shadows to increase realism and cohesion across ads
    
    

2. Dynamic Video Creation

The enhanced catalog assets were then integrated into CPV templates, transforming static product images into engaging, on-brand video ads that could scale across 1:1 & 9:16 placements.

3. Category Focus
To measure impact, Netshoes and ROI Hunter selected one strategically important product category “Supplements” and ran a structured A/B test.


4. Performance Testing
Ads were tested with clear control and test design, comparing standard CPVs against GenAI-powered CPVs to measure the uplift across key business metrics.

 

The combination of GenAI-enhanced catalog assets with CPV delivered impressive results for Netshoes:

• +93% Transactions
• +74% Conversion Rate
• +72% ROAS

These results demonstrate that creative quality and relevance can drive major performance improvements, without requiring additional budget. By transforming inconsistent product images into high-quality, engaging videos, Netshoes unlocked incremental revenue and stronger returns from their campaigns.

The success of this initiative has proven the value of combining Catalog Product Video with GenAI-powered asset enhancement. For Netshoes, this meant not only improving creative diversity, but also solving a long-standing challenge of catalog inconsistency from 3P sellers.

With +72% ROAS and nearly doubling transactions, GenAI CPV is now a core strategy in how Netshoes approaches catalog-driven advertising.
