Case Study: Science in Sport achieves an 82% conversion uplift with Yieldify

How Science in Sport used Yieldify to boost AOV and conversions

Science in Sport (SiS) is a UK-based developer and retailer of sports nutrition products sold through specialist retailers, grocers and online. Facing a booming market and increasingly health-conscious shoppers, SiS needed to improve its online customer experience to grow loyalty and encourage returning customers to make higher-value follow-up purchases.

Yieldify delivered bespoke on-site campaigns — including subtle product-page cross-sell notifications with multiple CTAs and an exit‑intent overlay promoting free delivery on orders over £25 — timed to target returning visitors. The tactics drove strong results: an overall 82% uplift in conversion rates, +155.5% conversion uplift from targeted returning customers (cross-sell) and +83.1% uplift from the free-delivery exit-intent campaign.
