Technical
Edge Cache Rules and TTL
Edge caching lowers latency, but bad TTL values cause stale surprises.
Group pages by volatility
Assign short TTL to pricing pages and long TTL to static assets.
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.
Design stable cache keys
Include only needed params so cache is not fragmented by noise.

Watch hit ratio by route
Monitor edge hit rate per template to find expensive misses.
