Seo Drift Monitor
Description
Detects when a deploy silently ships a noindex, drops a schema block, or rewrites your canonical. Baselines a page's SEO contract, diffs every change with Critical/Warning/Info severity, and points fixes to claude-seo sub-skills. A Claude Code skill. Open source.
Installation
This entry records only its repository, not the path inside it, so there is no
exact command to give. Open the source below and copy the folder into

**Git for SEO. Baseline your page, catch the silent regressions your deploys ship.**
Not a crawler. Not a rank tracker. Not a Lighthouse wrapper. This catches the moment a deploy silently flipped your canonical, dropped a JSON-LD block, or shipped `noindex` to prod — before Google notices.
Extension for the [claude-seo](https://github.com/AgriciDaniel/claude-seo) skill ecosystem for [Claude Code](https://docs.anthropic.com/en/docs/claude-code).

How It Works
Think of it like git for SEO. You **baseline** a page when it's in a good state, then **check** it later to see what broke.
1. Optimize a page with claude-seo
