Check canonical URL declarations against final fetched URLs, robots signals, redirects, target status, and duplicate canonical groups.

Inputs

This actor accepts the locked fields for actor 254: startUrls, sitemapUrls, htmlInputs, allowedDomains, maxPages, maxDepth, followRedirects, checkCanonicalTargetStatus, detectDuplicateCanonicalTargets, includeRobotsSignals, requestDelayMs, timeoutMs. URL and sitemap inputs use production fetch paths; supplied HTML, JSON, header, or XML records are offline inputs for controlled runs.

Output

Dataset rows use the approved fields: sourceUrl, finalUrl, httpStatus, canonicalUrl, canonicalType, canonicalStatus, canonicalFinalUrl, canonicalHttpStatus, redirectCount, canonicalMatchesFinalUrl, duplicateCanonicalGroupId, robotsIndexable, issueCode, severity, recommendation, evidenceSnippet. The actor also writes these local report artifacts: canonical-url-consistency-report.md, canonical-audit-results.csv, duplicate-canonical-targets.csv, canonical-redirect-issues.json, missing-canonicals.csv.

Public source provenance

Bounded canonical snapshots from https://www.apple.com/ and https://github.com/modelcontextprotocol/servers, observed 2026-07-12. Apple publishes a self canonical; the captured GitHub repository head did not expose a canonical link.

Billing and cost controls

This actor uses pay-per-event pricing. It charges actor-start, then page-audited before each dataset row, and audit-report-generated before report artifacts. maxChargeUsd is enforced locally and in Apify runs; when the limit is reached, uncharged rows and reports are withheld. Platform usage pass-through remains off.
