Google Shopping: How ba&sh Boosted Its ROAS by 52% Using Semantic AI
In the highly competitive fashion industry, visibility on Google Shopping is no longer enough. For e-commerce businesses, the real challenge is to reach an audience with genuine purchase intent. The key is to provide enriched product data, as this is what feeds the algorithms and allows them to leverage 100% of their targeting potential.
This is precisely what we were able to achieve for ba&sh. By relying on innovation and a data-first vision, we proved that campaign performance depends heavily on the accuracy of the information provided to the platforms.
The Challenge: Moving from Visibility to Qualified Profitability
For ba&sh, the challenge was twofold: maximizing impact during the crucial holiday season while optimizing budget efficiency. The issue identified was common to many businesses: product attributes that are sometimes underutilized, limiting Google’s understanding of the inventory.
The objective was clear: attract more qualified traffic, increase the conversion rate and ultimately generate a better return on advertising investment.
The Solution: Generative AI Serving the Catalog with Content Elevate
To meet this need, we deployed Content Elevate, our proprietary solution based on generative AI. This tool does more than simply correct feed errors; it provides genuine semantic enrichment.
By analyzing existing product data, Content Elevate generates key attributes such as descriptions, product details, or key points that are often missing or too brief in the original feed. This additional layer of data helps fill gaps in the catalog and provides Google with a granular understanding of the catalog.
Exceptional Results During the Christmas Period
The figures speak for themselves. Comparing performance over one month (November 24 to December 24, 2025 vs. the previous year), the impact of semantic enrichment is clear:
- +52% return on ad spend (ROAS).
- +49% conversion rate (CVR).
- +32% click-through rate (CTR).
- -9% decrease in cost per click (CPC).
Conclusion
These results demonstrate a virtuous cycle where, by improving the relevance of product data, we achieve better targeting from the moment of impression and performance levels rarely reached during these highly competitive periods.
The success of ba&sh confirms that semantic optimization has become a powerful and strategic lever for improving performance in search results.
Feed Focus: Data, the Engine of the Algorithm
At Feed Manager, we are convinced that the product feed is THE growth lever that allows brands to stand out today. The algorithms of Google Shopping, Meta, TikTok, and even marketplaces are “answer engines” that rely on the data provided. A poor or poorly structured feed condemns your products to invisibility or irrelevant distribution.
Semantic enrichment of product data and proper product management make it possible to transform a simple list of items into a strategic asset.
Would you also like to transform your product catalog and become more relevant?
