Case Study: Large Online Retailing Company achieves 17% purchase lift with SiteSpect personalized promotions

Large Online Retailing Company - Customer Case Study

A leading health‑food retail chain with a large online presence tested whether personalizing the home‑page promotional banner for its customizable subscription box—based on each visitor’s previous engagement with the promotion—would boost conversions and revenue. The brand hypothesized that tailoring messaging by engagement level would increase interest and purchases without harming sitewide revenue.

They ran a cross‑device A/B test with one variation offering three tailored messages: non‑engaged visitors received a first‑order discount; visitors who had clicked but not purchased saw a discount plus recommended items and a stronger CTA; past purchasers saw no discount but messaging to review and add items to their recurring order. Over a month, views rose 15%, add‑to‑bag actions increased 16% and purchases grew 17%; no negative revenue impact was observed, so the personalized messaging was rolled out sitewide and further tests (placement, imagery, CTAs) are underway.
