Technical
Stale While Revalidate in Real Projects
SWR improves perceived speed without forcing stale pages all day.
Set max age baseline
Choose a fresh window that matches how often each page changes.
Hvorfor det betyder noget
Technical quality protects every SEO and conversion initiative. If rendering, caching, and crawl directives are inconsistent, content quality alone cannot unlock growth.
Implementerings-tjekliste
- Document route behavior before changing render or cache settings.
- Ship changes behind measurable checks (logs, alerts, and audits).
- Validate canonical, robots, and status-code behavior in staging.
- Create rollback steps for cache and routing changes.
Almindelige fejl at undgå
- Changing multiple infrastructure variables in the same release.
- Relying on lab metrics only and ignoring field data.
- Treating cache invalidation as a manual afterthought.
Add SWR extension
Allow short stale serving while a background fetch gets new data.
