Web performance optimization is increasingly linked to user experience and search engine optimization (SEO) through Google’s Core Web Vitals. These metrics evaluate page usability by focusing on loading performance, such as Largest Contentful Paint (LCP), layout stability via Cumulative Layout Shift (CLS), and responsiveness through Interaction to Next Paint (INP).

While initial discussions focused on technical methods like link preloading to improve load speeds, the scope has expanded to include the direct economic impact of site latency. Data suggests that improvements in page load times can significantly increase conversion rates for major retailers. Developers are increasingly utilizing frameworks like Next.js to implement optimizations such as automatic code splitting to meet these performance standards.
