  4. Use a CDN for static assets
  5. See Core Web Vitals Explained for detailed guidance

    6. 2. Missing Security Headers#

    Symptoms: Security grade C or below

  7. See Security Headers Explained for server-specific instructions

    8. 3. SSL Issues#

  9. Fix mixed content (HTTP resources on HTTPS pages)
  10. Ensure proper certificate chain

    11. 4. SEO Problems#

    Symptoms: Missing meta tags, broken links, indexation issues

    Fix:

  11. Add title and meta description to all pages
  12. Fix broken links (404s)

    14. 5. Intermittent Downtime#

    Symptoms: Uptime below 99.5%, occasional timeouts
