Optimize first contentful paint
FCP is the first visual signal that a page is loading—fast FCP reassures users that the site is responding, reducing perceived wait time and bounce rates.
Quick Reference
- FCP measures time until first text/image appears—target under 1.8s
- Eliminate render-blocking CSS and JavaScript
- Inline critical CSS for above-fold content
- Use preconnect for third-party origins
Check
Measure FCP using Lighthouse or PageSpeed Insights. Verify first content appears within 1.8 seconds.
Fix
Optimize FCP by eliminating render-blocking resources, inlining critical CSS, and reducing server response time.
