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:

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

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

Always communicate the detected tier before running commands.

Quick Reference

/seo google pagespeed <url>

Combined Lighthouse lab data + CrUX field data.

/seo google crux <url>

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

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

Convention: After completing analysis, suggest: "Generate a report? Use /seo google report <type>"

Rate Limits

Cross-Skill Integration

• seo-sitemap: GSC sitemap status shows real crawl/index coverage
• seo-content: GSC query data informs keyword targeting

Technical Notes

• INP replaced FID on March 12, 2024. Never reference FID.

• 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).
