Extract and audit SEO metadata from the current browser page. Use when the user wants to check a page's SEO health, review meta tags, Open Graph, Twitter Cards, canonical links, structured data (JSON-LD), or diagnose why a page ranks poorly.
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
# Browser4 SEO ## Quick Start ```bash browser4-cli goto "https://example.com" # load the page to audit browser4-cli plugin-list # confirm browser4-seo is installed AND enabled # then call seo.extractMeta() — full SEO metadata extraction (see Tools below) ``` Extract and audit SEO metadata from the current page using the `browser4-seo` plugin's two tools. ## When to Use Use this skill when the user wants to: - **Check a page's SEO health** — "audit the SEO of this page", "is this page SEO-friendly?" - **Review meta tags** — "what's the title/description/canonical of this page?" - **Check Open Graph / Twitter Card** — "does this page have proper social share tags?" - **Review structured data** — "does this page have JSON-LD schema markup?" - **Diagnose ranking problems** — "why isn't this page ranking?" (SEO issues are a common cause) Do NOT use this skill for: - General content extraction — use the `browser4-cli` HTML snapshot / X-SQL instead. - Performance auditing (Core Web Vitals) — this plugin only covers SEO metadata, not performance metrics. ## How It Works …

How to install
mdr add platonai/browser4/browser4-seo@sha256:b057752b7efeaec3The line at the top of this page pins the label git:20260830.7520518, 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.
