# Google SEO APIs

Direct access to Google's own SEO data. Bridges the gap between crawl-based
analysis (existing claude-seo skills) and Google's real-time field data: actual
Chrome user metrics, real indexation status, search performance, and organic traffic.

All APIs are free. Setup requires a Google Cloud project with API key and/or
service account -- run `/seo google setup` for step-by-step instructions.

## Prerequisites

Before executing any command, check credentials:
```bash
python scripts/google_auth.py --check --json
```

Config file: `~/.config/claude-seo/google-api.json`
```json
{
  "service_account_path": "/path/to/service_account.json",
  "api_key": "AIzaSy...",
  "default_property": "sc-domain:example.com",
  "ga4_property_id": "properties/123456789"
}
```

If missing, read `references/auth-setup.md` and walk the user through setup.

### Credential Tiers

| Tier | Detection | Available Commands |
|------|-----------|-------------------|
| **0** (API Key) | `api_key` present | `pagespeed`, `crux`, `crux-history`, `youtube`, `nlp` |
| **1** (OAuth/SA) | + OAuth token or service account | Tier 0 + `gsc`, `inspect`, `sitemaps`, `index` |
| **2** (Full) | + `ga4_property_id` configured | Tier 1 + `ga4`, `ga4-pages` |
| **3** (Ads) | + `ads_developer_token` + `ads_customer_id` | Tier 2 + `keywords`, `volume` |

Always communicate the detected tier before running commands.

## Cross-Skill Integration

- **seo-audit**: Spawns `seo-google` agent for live CWV + indexation data (conditional)
- **seo-technical**: Uses pagespeed_check.py for real CWV field data
- **seo-performance**: CrUX field data supplements Lighthouse lab data
- **seo-sitemap**: GSC sitemap status shows real crawl/index coverage
- **seo-content**: GSC query data informs keyword targeting
- **seo-geo**: GSC search appearance data includes AI Overview references

## Output Format

- CWV metrics: traffic-light rating (Good / Needs Improvement / Poor)
- Performance reports: tables with sortable columns
- Always include data freshness note
- Save reports as `GOOGLE-API-REPORT-{domain}.md`
- Use templates from `assets/templates/` for structured output

## Technical Notes

- INP replaced FID on March 12, 2024. Never reference FID.
- CLS values from CrUX are string-encoded (e.g., "0.05"). Scripts handle parsing.
- CrUX 404 = insufficient traffic, not an auth error.
- Search Analytics data has 2-3 day lag.
- `round_trip_time` replaced `effectiveConnectionType` in CrUX (Feb 2025).
- Custom Search JSON API is closed to new customers (2025).

## Error Handling

| Scenario | Action |
|----------|--------|
| No credentials configured | Run `/seo google setup`. List Tier 0 commands that work with just an API key. |
| Service account lacks GSC access | Report error. Instruct: add `client_email` to GSC > Settings > Users > Add. |
| CrUX data unavailable (404) | Report insufficient Chrome traffic. Suggest PSI lab data as fallback. |
| GA4 property not found | Report error. Show how to find property ID in GA4 Admin > Property Details. |
| Indexing API quota exceeded | Report 200/day limit. Suggest prioritizing most important URLs. |
| Rate limit (429) | Wait and retry with exponential backoff. Report which API hit the limit. |
