The leroy merlin primary issues included poor search relevancy, with customers frequently unable to find the products they were looking for, even when those items were in stock. The existing system lacked the intelligence to understand synonyms, product variations, and customer intent, leading to a frustrating user experience. Additionally, the search functionality was slow, taking several seconds to return results, which significantly impacted user engagement and conversion rates.
From an SEO perspective, the company was struggling with poor search engine rankings for product pages, limited internal search visibility, and difficulty optimizing for voice search and mobile queries.
