Definition
Page load time represents the total duration needed for a web page to be completely loaded and interactive. It encompasses server response time (TTFB), resource downloading (HTML, CSS, JS, images, fonts), and browser rendering. Google considers load times exceeding 3 seconds lead to significantly higher bounce rates, with an estimated 32% visitor loss. Optimization involves image compression (WebP, AVIF), CDN usage, browser caching, CSS and JavaScript minification, and reducing HTTP requests.
Key Points
- Google recommends loading in under 3 seconds
- Each additional second increases bounce rate by 32%
- Key factors: image weight, HTTP requests, server time, and caching
Practical Examples
Impact on bounce rate
An e-commerce site with 6-second load time loses 40% of visitors. After optimization, the time drops to 2.1s.
Mobile/desktop comparison
A site loads in 1.5s on desktop but 5.8s on mobile 3G. Image optimization and lazy loading reduce mobile time to 2.3s.
