To improve our two most important pages from an SEO and SEM perspective, we started digging into how to improve their INP, a metric to assess web pages’ interaction speed. It was an R&D project driven by a clear goal baked by tons of data and assumptions. We spent a lot of time identifying what to optimize and made one-line changes and big refactors. We jumped onto React Server Components and Next.js App Router. We succeeded but also failed frequently. In this article, we will share the whole journey and the takeaways.
