SEO & Search Generative Experience (SGE)
Core Web Vitals and Server Performance
Core Web Vitals measure loading, interactivity, and visual stability. Many fixes are frontend, but server performance decides the starting line: time to first byte, cache hit rates, and backend latency. A fast server makes every other optimization easier; a slow one caps your scores no matter how good the frontend is.
Points clés
- Measure time to first byte and backend latency before touching frontend code.
- Cache HTML and API responses at the edge with sensible invalidation.
- Optimize database queries and indexes that back your pages.
- Use a CDN for static assets and compress responses with gzip or brotli.
- Pre-render or cache-heavy pages instead of rendering on every request.
- Right-size server resources and autoscale for traffic spikes.
- Reduce third-party scripts and tag managers that block rendering.
- Track field data in Search Console and CrUX, not just lab scores.
Questions fréquentes
Which Core Web Vital matters most?
It depends on the page; LCP for content pages, INP for interactive ones, CLS for layout stability.
Can server changes alone fix poor scores?
Often yes for LCP; INP and CLS usually need frontend work too.
How often should I check field data?
Weekly at minimum; trends matter more than single readings.
Do CDNs help with Core Web Vitals?
Yes, by cutting latency and improving cache hit rates for static assets.
