infrasity-labs Blog Google: Google API Data for Blog Performance
Direct access to Google's SEO APIs for blog performance analysis. Provides real Chrome user metrics, indexation status, search performance, entity analysis, YouTube video discovery, keyword volumes, and PDF/HTML performance reports.
All APIs are free at normal usage levels. Setup requires a Google Cloud project with an API key and/or service account.
Prerequisites
Always check credentials before running any command:
python3 skills/blog-google/scripts/run.py google_auth --check --json

Blog Workflow Integration
This skill is both user-invocable (/blog google pagespeed) and callable
internally by other blog sub-skills:
- blog-seo-check: Runs PSI + CrUX on published post URL for live CWV data
- blog-rewrite: NLP entity analysis to identify E-E-A-T entity gaps
- blog-geo: GSC performance data for real search appearance insights
- blog-audit: Batch CWV + indexation checks across all published blog URLs
- blog-write / blog-rewrite: YouTube search for video embedding
Falls back gracefully when credentials are not configured.
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 Chrome traffic, not an auth error.
- Search Analytics data has 2-3 day lag.
- Indexing API is officially for JobPosting/BroadcastEvent pages only.
- All Google APIs used are FREE at normal usage levels.
Error Handling
| Scenario | Action |
|---|---|
| No credentials configured | Run /blog google setup. List Tier 0 commands (API key only). |
| Service account lacks GSC access | Add client_email to GSC > Settings > Users > Add. |
| CrUX data unavailable (404) | Insufficient Chrome traffic. Use PSI lab data as fallback. |
| GA4 property not found | Find property ID in GA4 Admin > Property Details. |
| Indexing API quota exceeded | 200/day limit. Prioritize most important URLs. |
| Rate limit (429) | Wait and retry with exponential backoff. |
