# SEO Drift Monitor

Protect your SEO work from being broken by page changes. Baseline a page, detect regressions, get fix recommendations.

## Commands

| Command | Description |
|---------|-------------|
| `/seo-drift baseline <url>` | Capture a "known good" snapshot of all SEO-critical elements |
| `/seo-drift check <url>` | Compare current state against the most recent baseline |
| `/seo-drift history <url>` | Show all baselines and checks for a URL |

## Baseline Workflow

When the user runs `/seo-drift baseline <url>`:

1. Run the baseline capture script:
   ```bash
   python3 ~/.claude/skills/seo-drift/scripts/baseline.py "<url>"
   ```

2. Parse the JSON output and present a formatted summary:
   ```
   Baseline saved for [domain] (ID: [id])

   Title: [title]
   H1: [h1 text] ([h1_count] total)
   Schema: [schema_count] blocks ([schema_types])
   Canonical: [canonical]
   Robots: [robots or "none"]
   OG Tags: [og_tags count]
   CWV: [score]/100 (LCP: [lcp]s, FCP: [fcp]s, CLS: [cls])
   ```

3. If the script returns an error, display it and suggest fixes.

**Optional flags:**
- Add `--skip-cwv` to skip the PageSpeed Insights API call (faster)

## Check Workflow

When the user runs `/seo-drift check <url>`:

1. Run the check script:
   ```bash
   python3 ~/.claude/skills/seo-drift/scripts/check.py "<url>"
   ```

2. Parse the JSON output. If there's an error about no baseline, tell the user to run `/seo-drift baseline <url>` first.
