Case Study: e.l.f. Cosmetics achieves 19% higher order value and 4x mobile conversions with SLI Systems

A Beautiful Solution to Site Search

e.l.f. Cosmetics, a value-driven beauty brand selling online and through major retailers, needed a better site and mobile search because the default e‑commerce platform search failed to surface products and rich content like videos and blog posts, causing shoppers to abandon searches and increasing customer service load.

SLI Systems implemented Learning Search, Rich Autocomplete and Learning Recommendations, added refined, tabbed results for content types and optimized mobile search—making products and social content easier to find. The changes drove stronger engagement and sales: site search users convert at ~3× the rate of non-search users (4× on mobile), view three times as many pages, and saw a 19% increase in average order value and a 21% rise in average per-visit value.
