Background
Follow-up to #19301 , which de-duplicated the Troubleshooting and Custom Instrumentation title families.
Sentry docs render the browser <title> as frontmatter.title + " | Sentry for {Platform}" for platform/guide pages (app/[[...path]]/page.tsx:366). Product/API pages get no suffix. So the ~200 raw frontmatter-title duplicates (e.g. "Configuration" across every SDK) are mostly already unique at the tag level and are not a problem.
Accounting for that suffix and excluding version-variant pairs (__v7.x, etc., which share a URL via the version switcher), 35 groups / 77 pages still render a genuinely duplicate <title>. This issue tracks fixing them.
Categories
Three buckets, in rough priority order:
Same-platform collisions (17) — different pages on the same platform render an identical title; the platform suffix can't disambiguate. Highest value. Many are legacy-sdk vs common pairs (Integrations, Usage, Context, Source Maps) and instrumentation-vs-trace-propagation pairs.Product / non-platform collisions (15) — /product/ and /api/ pages get no suffix, so these are true duplicate <title> tags (e.g. 8× "Set Up", plus Authentication, Logs, Issues, Errors).Cross-guide, shared framework name (3) — two guides that share a display name (e.g. a .NET and a JS "AWS Lambda" guide) render the same X | Sentry for X. Arguably acceptable; may not need a change.
Recommended approach
Prefer descriptive, unique title; add sidebar_title to keep the menu label short where the section already provides context (the pattern established in docs: De-duplicate Troubleshooting and Custom Instrumentation page titles #19301
For legacy-sdk vs common pairs, consider whether the legacy page should be retitled ("Legacy …") or redirected, since some may be effectively superseded — worth an SME check.
Leave version-variant pairs alone (same URL).
