On-Page SEO Audit (by URL)

omnial/x402-seo-audit

Given a URL, returns an on-page SEO score plus the checks behind it: title and meta description length, heading structure, image alt-text coverage, canonical tag, Open Graph and schema.org markup, internal/external link ratio, and whether robots.txt and a sitemap are present -- along with a plain-language list of issues found and prioritized fixes.
