# Google SEO APIs
## Shared Data Cache

**Step 0 -- Check shared data cache:**

Before gathering, check `.seo-cache/` for reusable context from related SEO skills.
Reference: `../seo/references/shared-data-cache.md` for schemas and dependency map.

Check these cache files when present:
- `.seo-cache/site-meta.json` for domain, business type, industry, and crawl context
- `.seo-cache/audit-scores.json` for prior full-audit priorities
- `.seo-cache/pages/{url-slug}/page-analysis.json` for page-level context when a URL is provided

- If found: parse and use clearly valid fields (note "Using cached [X] from [date]")
- If missing, corrupt, or irrelevant: continue with fresh evidence
- If the user says "refresh" or "re-run": ignore cache reads and overwrite on write

Direct access to Google's own SEO data. Bridges the gap between crawl-based
analysis (existing codex-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/codex-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.

## PageSpeed + CrUX

### `/seo google pagespeed <url>`

Combined Lighthouse lab data + CrUX field data.

**Script:** `python scripts/pagespeed_check.py <url> --json`
**Reference:** `references/pagespeed-crux-api.md`
**Default:** Both mobile + desktop strategies, all Lighthouse categories.

Output merges lab scores (point-in-time Lighthouse) with field data (28-day
Chrome user metrics). CrUX tries URL-level first, falls back to origin-level.

### `/seo google crux <url>`

CrUX field data only (no Lighthouse run). Faster.

**Script:** `python scripts/pagespeed_check.py <url> --crux-only --json`

### `/seo google crux-history <url>`

25-week CrUX History trends. Shows whether CWV metrics are improving, stable, or degrading.

**Script:** `python scripts/crux_history.py <url> --json`
**Reference:** `references/pagespeed-crux-api.md`

Output includes per-metric trend direction, percentage change, and weekly p75 values.

## Search Console

### `/seo google gsc <property>`

Search Analytics: clicks, impressions, CTR, position for last 28 days.

**Script:** `python scripts/gsc_query.py --property <property> --json`

**Default:** 28 days, dimensions=query,page, type=web, limit=1000.

Includes quick-win detection: queries at position 4-10 with high impressions.

### `/seo google inspect <url>`

URL Inspection: real indexation status from Google.

**Script:** `python scripts/gsc_inspect.py <url> --json`

Returns: verdict (PASS/FAIL), coverage state, robots.txt status, indexing state,
page fetch state, canonical selection, mobile usability, rich results.

### `/seo google inspect-batch <file>`

Batch inspection from a file (one URL per line). Rate limited to 2,000/day per site.

**Script:** `python scripts/gsc_inspect.py --batch <file> --json`
