Web Performance
The speed and efficiency with which web pages load and respond to user interactions, directly impacting UX and SEO.
What Is Web Performance?
Web performance encompasses how fast a website loads, how quickly it responds to interactions, and how smooth it feels during use. Key metrics include Largest Contentful Paint (LCP), Interaction to Next Paint (INP), and Cumulative Layout Shift (CLS)—collectively known as Core Web Vitals. Performance is a confirmed Google ranking factor and directly impacts conversion rates: every 100ms of added load time reduces conversions by up to 7%
Optimization techniques include image compression, code splitting, caching, CDN usage, and lazy loading.
