Font Optimization
Font optimization is a web performance technique focused on improving how fonts are loaded, rendered, and displayed on websites to enhance user experience and Core Web Vitals. It involves strategies like font subsetting, preloading, using modern font formats (e.g., WOFF2), and minimizing layout shifts. The goal is to reduce page load times, ensure text is visible quickly, and avoid performance bottlenecks caused by large or poorly managed font files.
Developers should learn font optimization to improve website performance, especially for better SEO rankings and user engagement, as slow font loading can lead to poor Core Web Vitals scores like Cumulative Layout Shift (CLS) and Largest Contentful Paint (LCP). It's crucial for content-heavy sites, e-commerce platforms, and any project prioritizing accessibility and fast loading on mobile devices. Implementing font optimization helps reduce bounce rates and ensures a smooth, professional user experience.
