About SchemaCraft AI
SchemaCraft AI is a free audit for SEO and AI search visibility. It fetches pages from its own server, scores only what it can verify, and shows the evidence for every point.
What this product does
SchemaCraft AI answers one question: can search engines and AI assistants reach, read and quote a page? The audit runs about 50 checks across technical SEO, crawlability, content, entity schema and AI readiness. Alongside it are free generators and validators for robots.txt, llms.txt and JSON-LD. Everything is free, with no account and no paywall.
How the audit is computed
The page is fetched from SchemaCraft servers at /api/audit. The response includes the final HTTP status, redirect chain, response headers, raw HTML, robots.txt, and extracted JSON-LD blocks. Scores are calculated only from that evidence. If HTML cannot be retrieved, the report shows that the audit did not complete. Checks without evidence are labeled Not assessed and are excluded from the score.
How the score is calculated
- Every check has a severity weight: critical 5, high 3, medium 2, low 1. Informational checks carry no weight.
- A pass earns full credit, a warning half, a fail none. Not-assessed checks are left out entirely.
- Each of the five categories is the weighted average of its checks. The overall score weights them: technical SEO 20%, crawlability 20%, content and answerability 20%, entity and schema 15%, AI search readiness 25%.
- Hard caps stop a good-looking average from hiding a blocker: a page that is noindexed or blocked for Googlebot is capped at 40, and a page whose content needs JavaScript or has under 80 words is capped at 50. The report always says when a cap applied and why.
- Blocking AI training crawlers (GPTBot, ClaudeBot, Google-Extended and similar) is a policy choice and does not lower the score. Blocking AI search crawlers does.
What the score does not measure
Backlinks, domain authority, search demand and competition. A page can score 95 and still rank poorly if other sites are more trusted for the topic. The score tells you whether anything on the page is stopping search engines and AI assistants from using it.
Who it is for
SEO agencies, independent consultants, and technical founders who need a fast, inspectable diagnosis instead of a black-box grade. It is not a ranking guarantee, a Google partner product, or a substitute for Search Console.
