Technical
Cache Invalidation for Growth Teams
Strong cache rules boost speed, but stale content kills trust.
Define cache layers
Map browser, CDN, and app cache behavior in one shared sheet.
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.
Purge by content events
Invalidate only changed paths right after publish instead of global clears.
