Website Performance & SEO Foundations in 2025

Aug 4, 2025• 6 min read

Technical performance and search optimization share the same north star: delivering relevant value fast.

Core Web Vitals Focus

  • LCP: Optimize hero media (preload, compress, correct dimensions)
  • CLS: Reserve space for images & dynamic components
  • INP (successor to FID): Keep main thread light; audit JS bundles quarterly

Rendering Strategy

Prefer static generation for marketing and educational content. Hydrate only what must be interactive. Audit “islands” that stay idle.

Caching & CDN

  • Immutable asset hashes
  • Stale-while-revalidate for HTML when dynamic (or full static export when feasible)
  • Edge redirects instead of client-side route guards

Metadata Automation

Automate: sitemap, robots, canonical, JSON-LD, open graph images. Manual steps drift.

Content Structure

Answer intent early; use semantic headings; include concise FAQ (can power rich results with FAQPage schema when appropriate).

Monitoring

Track Web Vitals in-field (e.g., with web-vitals library) and correlate to conversion events.

Continuous Improvement Loop

  1. Collect field data
  2. Diagnose regressions (bundle diff, layout shift trace)
  3. Remediate
  4. Record in change log

Foundations compound—treat them as product features, not one-off tasks.
