Unlocking Efficiency with AI: How SPARC Brands Optimized Conversion for Website Traffic with Agentic AI

As an innovator in digital commerce, SPARC had already optimized key performance channels, from PDP and PLP experiences to double-digit growth in paid social acquisition. Yet, even for top innovators, there is always room to push performance further. SPARC chose Forever 21 as the first brand partner to work with Spangle to unlock new opportunities to drive efficiency, scale customer acquisition, and elevate its digital shopping experience beyond traditional optimization strategies.

The challenge

Seizing the Opportunity for AI-Driven Growth

SPARC recognized the potential to enhance marketing efficiency, improve new customer acquisition, and create deeper connections between paid traffic and shopping behavior. Forever 21 recognized a key opportunity to enhance the customer experience by aligning its high-performing ads with its fast-moving inventory. The brand's paid social strategy effectively drove significant traffic to “New Arrivals” pages, which historically converted well. However, the rapid pace of merchandising updates meant that products featured in ads were often pushed down the page—or even out of stock—before shoppers arrived, creating a disconnect between the ad experience and the on-site journey. While the Forever 21 team saw the potential to refine this approach, manually updating ads to match real-time inventory shifts was not scalable. To unlock greater efficiency and maximize conversions, they needed a dynamic solution that could bridge the gap between paid social creative and live product availability—at scale.
