16 plugins × site-wide crawl. Meta tags, structured data (JSON-LD/Microdata/RDFa), canonical, hreflang reciprocity, sitemap + robots.txt syntax, broken link, duplicate content, freshness, Lighthouse SEO. Not just one URL — the whole site, sitemap parse + BFS fallback up to 500 pages in parallel.
Every finding ships with confidence taxonomy + methodology + limitations; auditors can't ask "how did you measure this?" — the answer is in the report.
One URL, 16 Visibility plugins in parallel. Site-wide report + per-URL drill-down + dedup ready.
