robots.txt and noindex Basics
robots.txt and noindex serve different jobs and must not be mixed.
Use robots for crawl paths
Block private or duplicate paths, but keep valuable URLs crawlable.
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.
Use noindex for visibility control
Apply noindex to pages you want crawled but excluded from results.
