Case Study: Forever 21 achieves 23.6% conversion lift and 10x ROI with Session AI

How Forever 21 uses behavioral AI to create better customer experiences – and improves conversion at the same time

Forever 21, the fast-fashion retailer, wanted to reduce its heavy reliance on broad sitewide promotions while boosting conversion, revenue per visit and top-line revenue. To achieve this, the brand sought a way to deliver more targeted, real-time incentives on its website and selected Session AI’s in-session marketing platform to help influence both anonymous and known visitors without eroding margins.

Session AI implemented real-time offers and dynamic segmentation on Forever 21’s US site, delivering targeted threshold-based discounts and alternative enticements to high-intent visitors. The campaign drove a 23.6% lift in conversion rate and a 23.3% increase in revenue per visit for on-the-fence shoppers, producing an immediate 10x ROI (projected to grow to 12–15x) while preserving margins and improving promotional efficiency.
