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.

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).

Pptx

Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions "deck," "slides," "presentation," or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill.
