Online Experiment Setup
Prefixbox conducted an A/B test on Bauhaus Czechia’s online store for one week in 2024 September, in which website visitors were split evenly into two groups (50-50%).
The Control group was shown Prefixbox’s Semantic Search Engine, while the Treatment group was shown Prefixbox’s AI Search Engine utilizing vector search technology.
While Prefixbox typically runs tests for 2-4 weeks, Bauhaus was so impressed by the results after just one week that they requested the AI Search be implemented immediately to start generating additional revenue.
45.3% increase in Revenue
The audience segment that saw Prefixbox AI Search results generated an impressive 45.3% more revenue compared those who saw results returned by the text-matching based Semantic Search Engine.
This remarkable revenue increase was due to the fact that Prefixbox’s AI Search Engine delivers more relevant results.
28.4% increase in Average Order Value
AI Search users placed orders with a 28.4% higher value on average, making a substantial contribution to the overall revenue uplift.
18.4% increase in Transactions
The treatment segment receiving the AI Search Engine results also made 18.4% more transactions, so orders were not only of higher value but also more frequent.
10.9% increase in Cart Events via Search
Prefixbox AI Search users made 10.9% more cart events after using the search than the Control group, signalling that general result relevancy was improved.
6.1% increase in Search Engine Result Page Clicks
The number of clicks on products on the SERP increased 6.1% for shoppers who saw results powered by the AI Search Engine, as the results were more relevant.

Bauhaus Czechia catapulted its online revenue and improved user engagement by implementing Prefixbox’s AI Search Engine.
The new AI Search Engine demonstrated outstanding performance in a test, generating 45.3% more revenue, a 28.4% increase in average order value, and an 18.4% rise in transactions compared to their previous Semantic Search Engine.
