GC Wellbeing

The objective

GC Wellbeing, a leading Korean health supplement brand, has traditionally catered to consumers in their 30s to 50s. As wellness content gained traction among younger audiences, the brand recognised a growing opportunity to reach a new generation of health-conscious shoppers. 

With Black Friday approaching, GC Wellbeing wanted to showcase its diverse supplement lineup in a way that would maximise visibility and expand reach beyond its usual customer base. To do so, they needed a smarter, data-driven approach that could highlight multiple SKUs and personalise recommendations to different users.

The solution

GC Wellbeing adopted Catalog Ads, an AI-powered solution built to streamline multi-SKU marketing and deliver tailored product experiences at scale. Catalog Ads automatically pull images, videos and product details from a brand’s catalog to dynamically generate personalised ad creatives for each viewer. 

By pairing Catalog Ads with Smart+, GC Wellbeing was able to automate key elements of the campaign, including creative variations, interactive add-ons, audience delivery and budget optimisation. The solution ensured each viewer received the most relevant supplement recommendation based on their interests and browsing behaviour. 

Smart+ Catalog also enabled the brand to pair engaging videos with dynamic product cards with real-time optimisation. This simplified the process of promoting multiple SKUs simultaneously and enabled the brand to efficiently showcase its full product range during the high-traffic Black Friday period.

The result

The Smart+ Catalog strategy delivered strong commercial impact. GC Wellbeing achieved a 6.3x Return on Ad Spend (ROAS), demonstrating highly efficient revenue generation from the campaign. In addition, Cost Per Action (CPA) decreased by 30%, while Conversion Rate (CVR) improved by 40%. These results highlight the incremental value of Smart+ Catalog in driving broader reach, smarter targeting and more efficient conversions.
