What is Page Speed?
Page speed measures how fast your web page loads and becomes interactive. It's both a ranking factor for search engines and a critical component of user experience.
Page Speed Metrics
- TTFB (Time to First Byte) - Server response time
- FCP (First Contentful Paint) - When first content appears
- LCP (Largest Contentful Paint) - When main content loads
- TTI (Time to Interactive) - When page becomes usable
- Total page load time - Complete page load
Why Page Speed Matters
User experience:
- 53% of mobile users leave if page takes >3 seconds
- Each second of delay reduces conversions
- Faster sites have lower bounce rates
SEO:
- Direct ranking factor since 2010
- Core Web Vitals ranking signal since 2021
- Affects crawl efficiency
