Expanded explanation

## Why Page Speed Matters for SEO

Speed is a confirmed ranking signal and a direct driver of user experience. Every extra second of load time increases bounce rates. Google has been clear that faster pages get a ranking advantage, and users have zero patience for slow sites.

## How Page Speed Works

Page speed is affected by server response time, file sizes (images, CSS, JS), number of requests, caching, CDN usage, and how the browser renders content. You measure it with tools like Google PageSpeed Insights, WebPageTest, and Chrome DevTools. Optimisation is about reducing bytes, requests, and render-blocking resources.

## Common Mistakes

- Chasing a perfect Lighthouse score instead of fixing real-user bottlenecks
- Adding heavy plugins and tracking scripts without measuring their impact
- Optimising desktop speed but ignoring mobile on a slower connection
