Crawl and Indexing Readiness for JavaScript Utility Sites

Client-rendered utility sites need explicit crawl signals. This checklist prioritizes canonical consistency and crawl-visible route context.

Technical checklist

• Use a single canonical URL pattern for each route and locale.
• Return real HTTP 404 for unknown paths; avoid generic soft-404 shells.
• Expose stable metadata, titles, and descriptions in prerendered HTML.
• Keep sitemap entries fresh and aligned with actually served URLs.

Review diagnostics

• Audit a sample of tool routes with curl to confirm indexable HTML content exists.
• Check redirect chains and remove unnecessary multi-hop redirects.
• Keep crawl assets and policy pages linked from global navigation.
