Noindex inventory governance

Labs keeps experimental tools away from the indexed core.

This area organizes non-core tools without letting weak inventory dilute the main FreeToolsBox surface. Labs and hub pages are noindex, ad-free, and excluded from the sitemap until they meet a real workflow standard.

Hub map

Consolidation hubs

Small single-purpose tools are mapped into fewer, stronger workbench pages. These hubs are intentionally not part of the sitemap yet.

noindex-hub

Text Utilities Workbench

A planned hub for small text tasks that are useful together but too thin as separate indexed pages: counting, case conversion, deduplication, slug creation, and placeholder text.

5 legacy tools mapped

noindex-hub

Code Formatters Workbench

A planned hub for CSS, HTML, JavaScript/TypeScript, SQL, SVG, and entity cleanup tasks that are stronger as a formatter workflow than as separate thin pages.

6 legacy tools mapped

noindex-hub

Image Utilities Workbench

A planned hub for browser-side image compression, cropping, Base64 conversion, QR/barcode generation, color utilities, and EXIF inspection.

9 legacy tools mapped

noindex-hub

AI Prompt Workbench

A cautious experimental hub for prompt cleanup, prompt templates, AI output cleanup, token estimates, conversation analysis, and model planning snapshots.

Rules

Promotion policy

  • • Only promoted focused core tools are indexable tool pages; new candidates move into sitemap only after a manual quality gate.
  • • Hub pages are noindex, ad-free, and excluded from sitemap until they replace multiple legacy pages with a real workflow.
  • • Labs is noindex and reserved for experimental or broad utilities that should not dilute the core directory.
  • • Legacy one-off pages stay noindex, ad-free, and out of public navigation unless they are promoted through the quality gate.
  • • No page can move into sitemap without examples, edge-case notes, privacy guidance, accessible controls, and a related concept guide.
