Definition
SEO Health asks whether the live site is technically ready to be found and understood across technical setup, structure, and content. The review includes robots rules, status codes, crawl paths, noindex signals from meta robots or X-Robots-Tag, canonicals, hreflang, soft 404s, and XML sitemaps with their coverage, freshness, and indexation mismatches. An SEO audit reviews how pages can be crawled, indexed, and understood, and it does not guess a future ranking.
Short answer
Discovery health should stay separate from page clarity, so a crawl checklist is not treated as a judgment of the answer. Broken internal links waste crawl paths and trust, orphan pages have no internal links, and the canonical should point to the intended indexable URL.
What to check
- Review robots rules and status codes
- Repair broken links and orphan pages
- Point canonicals at indexable URLs
- Compare sitemaps with indexation
What this does not claim
A clean SEO Health reading does not guarantee rankings or citations, and clearing warnings does not guarantee rankings or citations either. Hreflang checks language alternates without guessing rankings, and the audit does not sell a future position.
A practical example
On this site English is served at the root and Chinese is served under /zh/, with hreflang values en, zh-Hans, and x-default to English, and there is no /en/ prefix. Public notes from the MIT repository open-seo-crawler list titles, sitemaps, hreflang, duplicates, broken links, noindex, status codes, canonicals, and soft 404s as a coverage map rather than a scoreboard, and this essay does not claim that Mika copied that project's docs.
