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:

python3 scripts/google_auth.py --check --json

Config file: ~/.config/claude-seo/google-api.json

{
  "service_account_path": "/path/to/service_account.json",
  "api_key": "<GOOGLE_API_KEY>",
  "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 |

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 submitted counts, errors, and warnings; use URL Inspection for indexation truth
• 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. |
