Speed = money
Amazon found that every 100ms of delay costs 1% of revenue. Google confirmed that 53% of mobile users abandon a page that takes longer than 3 seconds to load.
Core Web Vitals
Google measures three key metrics: LCP (Largest Contentful Paint), FID (First Input Delay), and CLS (Cumulative Layout Shift). These metrics directly affect your search rankings.
Image optimization
Images make up an average of 50% of page size. Use WebP format, lazy loading, and responsive srcset for different screen sizes.
CDN and caching
A Content Delivery Network distributes your website to servers worldwide. Visitors always communicate with the nearest server, dramatically reducing latency.
Code minimization
Minify CSS and JavaScript, remove unused code, and load scripts asynchronously. Every kilobyte counts.
How to measure
Google PageSpeed Insights, GTmetrix, and WebPageTest are free tools for measuring speed. Test regularly and monitor the trend.
