Use when the user asks to "audit on-page SEO" or "diagnose why a single page dropped"; scores titles, meta, header structure, keyword placement, links, and images with prioritized fixes. Not for E-E-A-T / publish-readiness scoring — use content-quality-auditor; not for crawl / CWV / indexing — use technical-seo-checker. 页面SEO审计/排名诊断.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# On-Page SEO Checker This skill audits the structural on-page SEO signals a single page controls and provides actionable, prioritized recommendations. ## What This Skill Does Audits structural on-page signals (title tag, meta description, header structure, keyword placement, internal/external links, images) with scored results and prioritized fix recommendations. For E-E-A-T and publish-readiness scoring, hand off to [content-quality-auditor](../content-quality-auditor/SKILL.md); for crawl, indexing, and Core Web Vitals, use [technical-seo-checker](../technical-seo-checker/SKILL.md). ## Quick Start Start with one of these prompts, then finish with the standard handoff summary from [Skill Contract](../../../references/skill-contract.md). ### Audit a Single Page ``` Audit the on-page SEO of [URL] ``` ``` Check SEO issues on this page targeting [keyword]: [URL/content] ``` ### Compare Against Competitors ``` Compare on-page SEO of [your URL] vs [competitor URL] for [keyword] ``` ### Audit Content Before Publishing ``` Pre-publish SEO audit for this content targeting [keyword]: [content] ``` ### Site-Wide / Bulk Audit (5+ URLs) …

How to install
mdr add jahidulislamseo/antigravity-ai-skills/on-page-seo-checker@sha256:0ec9eb013e2eb8d2The line at the top of this page pins the label v20.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
