What it checks

Built for multilingual sites, with fewer false positives.

Hreflang

HTML, XML sitemap and HTTP-header alternates, self references, reciprocal targets, indexability and canonical consistency.

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 and detectable dimensions.

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 and same-host links using a different scheme or port.
