# SEO Drift Monitoring
|
|
|
|
"Git for SEO" — captures baselines of SEO-critical page elements, then diffs against current state to detect regressions. Contributed to [[Claude SEO]] v1.9.0 by Dan Colta.
|
|
|
|
## What It Tracks
|
|
|
|
17 comparison rules across 3 severity levels:
|
|
|
|
| Severity | Examples |
|
|
|----------|----------|
|
|
| CRITICAL | Schema removed, canonical changed, noindex added, H1 removed |
|
|
| WARNING | Title changed, CWV regression >20%, meta description changed |
|
|
| INFO | H2 structure changed, content hash changed, image count changed |
|
|
|
|
## Architecture
|
|
|
|
- **SQLite persistence** at `~/.cache/claude-seo/drift/baselines.db`
|
|
- **4 Python scripts**: `drift_baseline.py` (capture), `drift_compare.py` (diff), `drift_report.py` (HTML report), `drift_history.py` (timeline)
|
|
- **Security-hardened**: uses only `fetch_page.py` for URL fetching (SSRF-protected). Original submission had a curl fallback that bypassed SSRF protection — completely removed during integration.
|
|
|
|
## Commands
|
|
|
|
```
|
|
/seo drift baseline <url> # Capture current state
|
|
/seo drift compare <url> # Compare against baseline
|
|
/seo drift history <url> # Show all checks over time
|
|
```
