In this presentation, we will explore Leroy Merlin's technical journey to overcome ranking and performance penalties caused by Google's Core Web Vitals metrics. Knowing that a website's conversion rate can drop by an average of 5% for every second a consumer is unable to view the page, our team migrated the architecture from Client-Side Rendering to Server-Side Rendering (SSR) using Next.js.

We will cover the technical details of this evolution, highlighting how it became a major cross-functional project involving three key teams: the core Development squad, the UX team, and the DevOps team. Together, this collaborative effort enabled the implementation of a new header (the Backpack project), Cloudflare Cache integration, robust monitoring setups, and the adoption of a new Design System.

Finally, we will demonstrate the real-world results of this transformation:
• Substantial improvements in loading time (LCP) and achieving unprecedented Google Page Speed scores for SEO metrics.
• A reduction of 6 percentage points in the exit rate on the Homepage.
• A projected business impact capable of generating over 12,000 additional orders and R$ 8.7 million in incremental annual revenue by expanding SSR to modular pages.
• An additional projection of R$ 15,866,663.09 (approx. € 2,938,270.00) in incremental revenue directly from the Product Detail Pages (PDP).
