checksmithcats/canonical-hreflang-bulk-qa

Scan public static HTML for canonical and hreflang link-tag signals before launches, migrations, or template changes.

Hreflang Cluster Auditor

Audit hreflang clusters, language and region codes, reciprocal return links, x-default coverage, and canonical conflicts.

Canonical Hreflang Auditor

junipr/canonical-hreflang-auditor

Audit canonical and hreflang relationships, reciprocal tags, conflicts, and international SEO risks.

Audit a public page's hreflang alternate tags in one API call. Reports x-default, duplicate and invalid values, self-reference, score, and recommendations for international SEO QA.

Validate hreflang annotations after a domain or site migration: locale syntax, duplicates, target health, canonicals, x-default, self-references, reciprocal return links, and old-domain references.

Validate hreflang implementation (<link rel="alternate" hreflang=...>) to prevent international SEO issues. Detects missing/duplicate hreflangs, invalid language-region codes, missing self reference, and optional reciprocal hreflang checks.

Audit hreflang return links and language mappings from existing crawl data before multilingual launches or migrations. JSON input; up to 1,000 pages per run. Missing pages are marked unverified. $1 per 1,000 page results plus a small start fee. No live crawling.
