Case Study: Hirmer boosts site-search conversions 800% and cuts “no results” from 35% to 3% with Celebros' Concept-Based Semantic Site Search

Hirmer - Customer Case Study

Hirmer, Germany’s leading mens apparel super store, faced a failing site search: their legacy text-based engine returned “no results found” for 35% of queries, driving high bounce rates and low conversions. To better reflect their high-touch in-store service online, Hirmer engaged Celebros to deploy concept-based semantic site-search and conversion technologies to improve relevance, speed, and the overall shopping experience.

Celebros implemented its semantic site-search (powered by 250 NLP algorithms and delivered via the Celebros Conversion suite/OXID extension), adding fast <0.05s responses, auto-complete suggestions, and attribute-aware query handling. After launch, “no results” pages fell from 35% to ~3%, search accuracy and speed improved, and site-search user conversions rose by 800%, demonstrating clear measurable impact from Celebros’ solution.
