What it checks
Built for multilingual sites, with fewer false positives.
Metadata
Missing and duplicate titles/descriptions with language-aware duplicate handling and low-severity display heuristics.
Canonical
Missing, invalid or multiple canonical tags and pages that canonicalize elsewhere.
Social
Open Graph and Twitter/X metadata plus image URL, status, content type, detectable dimensions and explicit check coverage.
Sitemaps & links
robots.txt rules, sitemap discovery, crawl coverage, orphan candidates, crawl depth, contextual links and independent checks for uncrawled link targets.
Structured data
JSON-LD syntax parsing, discovered schema types and cautious semantic checks for common rich-result structures.
Content quality
Exact body-content duplicates, conservative language detection, H1 structure, thin-content heuristics and missing image alt attributes.
Redirects
Redirect chains, temporary redirects, sitemap redirects, host aliases and same-host links using a different scheme or port.
Patterns & provenance
Repeated issue root causes, canonical-preferred host inference, and the sitemap, internal-link, hreflang, canonical, redirect or start signal that brought each URL into the audit.
Change tracking
Compare a previous JSON export locally to see new and fixed issues, new or removed pages, and important page-level changes.
Staging → live
Mark pre-launch audits as staging, treat intentional noindex/robots protection as expected, and compare staging paths to production even when the hostname changes.
