Leroy Merlin Brasil achieves 31% CTR increase and $28M annual revenue boost with Algolia AI Search

Leroy Merlin Brasil's existing Elasticsearch search engine was too inflexible to scale, requiring significant developer involvement for even simple changes, while poor speed and irrelevant results degraded the customer experience across its large, diverse product catalog spanning multiple complex categories.

Outcome

Leroy Merlin Brasil achieved a 31% increase in click-through rate, a 15% increase in add-to-cart from search, and an estimated annual revenue increase of more than $28 million, while business teams can now independently manage and optimize search without large dedicated technical staff.

What failed first

The previous Elasticsearch search engine required developers to constantly debug and manually analyze search result rankings, and even simple changes demanded full team involvement and significant coding.
