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.

Most integrations have no usage fee within their documented quotas. Cloud Natural Language requires billing and can incur charges after its free monthly tier. Google Ads requires an eligible account and developer token. Never enable billing or make a paid request without explicit user approval.

Prerequisites

Always check credentials before running any command:

python3 skills/blog-google/scripts/run.py google_auth --check --json

Config file: ~/.config/claude-seo/google-api.json (shared with claude-seo)

{
  "api_key": "YOUR_GOOGLE_API_KEY",
  "oauth_client_path": "/path/to/client_secret.json",
  "default_property": "sc-domain:example.com",
  "ga4_property_id": "properties/123456789",
  "ads_developer_token": "...",
  "ads_customer_id": "123-456-7890",
  "ads_login_customer_id": "123-456-7890"
}

If missing, read references/auth-setup.md and walk the user through setup.

PageSpeed + CrUX

/blog google pagespeed <url>

Combined Lighthouse lab data + CrUX field data for a published blog post.

Script: python3 skills/blog-google/scripts/run.py pagespeed_check <url> --json Reference: references/api-reference.md

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.

/blog google crux <url>

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

Script: python3 skills/blog-google/scripts/run.py pagespeed_check <url> --crux-only --json

/blog google crux-history <url>

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

Script: python3 skills/blog-google/scripts/run.py crux_history <url> --json

---

Search Console

/blog google gsc <property>

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

Script: python3 skills/blog-google/scripts/run.py gsc_query --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.

The dedicated Search Console generative-AI reports are a gradual, subset rollout in the Search Console UI. They have separate Search and Discover views; the Search view covers AI Overviews and AI Mode. Do not promise clicks, queries, or API retrieval from these dedicated views. Until Google documents an API, report that capability as SKIPPED or unavailable and point the user to the UI.

Google's July 29 Search Central announcement says Search Console platform properties for Instagram, TikTok, X, and YouTube are globally available. The current Help Center still says gradual rollout. Report this as a Google-source conflict, verify availability in the user's account, and do not claim that /blog google gsc retrieves these platform reports through the current API.

/blog google inspect <url>

URL Inspection: real indexation status from Google.

Script: python3 skills/blog-google/scripts/run.py gsc_inspect <url> --json

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

After a canonicalization fix, Google may retain the URL in a duplicate cluster for up to two weeks. If the implementation is now correct and the fix is within that window, report PENDING_REEVALUATION rather than an immediate failure. Search Console's Request Indexing feature is quota-limited; reserve it for important URLs.

For batch inspection: python3 skills/blog-google/scripts/run.py gsc_inspect --batch <file> --json

---

Indexing API

/blog google index <url>

Notify Google of a URL update through the Indexing API.

Script: python3 skills/blog-google/scripts/run.py indexing_notify <url> --json Reference: references/api-reference.md

The Indexing API is officially for JobPosting and BroadcastEvent/VideoObject pages. Always inform the user of this restriction. Daily quota: 200 publish requests. Do not present it as a general-purpose replacement for URL Inspection's Request Indexing feature.

For batch: python3 skills/blog-google/scripts/run.py indexing_notify --batch <file> --json

---

GA4 Traffic

/blog google ga4 [property-id]

Organic traffic report: daily sessions, users, pageviews, bounce rate, engagement.

Script: python3 skills/blog-google/scripts/run.py ga4_report --property <id> --json Default: 28 days, filtered to Organic Search channel group.

For top landing pages: python3 skills/blog-google/scripts/run.py ga4_report --property <id> --report top-pages --json

---

YouTube (Video Discovery)

YouTube research can add useful, relevant media and distribution context. Any third-party visibility correlation is observational, not a Google ranking or citation requirement. Free, API key only. Used by blog-write and blog-rewrite for video embedding.

/blog google youtube <query>

Search YouTube for videos relevant to a blog topic.

Script: python3 skills/blog-google/scripts/run.py youtube_search search "<query>" --json Quota: 100 units per search (10,000 units/day free).

Returns: title, channel, views, likes, duration, description, tags.

For video details + comments: python3 skills/blog-google/scripts/run.py youtube_search video <video_id> --json

---

NLP Content Analysis

Google's entity and sentiment analysis can support topic and editorial review. It does not expose ranking-system scores, and E-E-A-T is not a numeric Google ranking factor.

/blog google nlp <url-or-text>

Full NLP analysis: entities, sentiment, content classification.

Script: python3 skills/blog-google/scripts/run.py nlp_analyze --url <url> --json Free tier: 5,000 units/month. Requires billing enabled on GCP project.

For entity extraction only: python3 skills/blog-google/scripts/run.py nlp_analyze --url <url> --features entities --json

---

Keyword Research (Google Ads)

Gold-standard keyword volume data. Requires Google Ads account (Tier 3).

/blog google keywords <seed>

Generate keyword ideas from seed terms for blog topic research.

Script: python3 skills/blog-google/scripts/run.py keyword_planner ideas "<seed>" --json

For volume lookup: python3 skills/blog-google/scripts/run.py keyword_planner volume "<kw1>,<kw2>" --json

---

Reports

/blog google report <type>

Generate a PDF/HTML report with charts and tables.

Script: python3 skills/blog-google/scripts/run.py google_report --type <type> --data <json> --domain <domain> --format pdf

Type	Input	Output
cwv-audit	PSI + CrUX + CrUX History data	Core Web Vitals audit with gauges, timelines
gsc-performance	GSC query data	Search Console report with query tables
indexation	Batch inspection data	Indexation status with coverage donut
full	All data combined	Comprehensive Google SEO report

Note: PDF generation requires system libraries: sudo apt install libpango1.0-dev libcairo2-dev. Falls back to HTML if WeasyPrint is unavailable or PDF rendering fails.

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.

Report Templates

Use the bundled templates when a workflow requests a durable human-readable report. Keep unavailable account data marked SKIPPED; never fill an empty section with estimated metrics.

• assets/templates/cwv-audit-report.md for PageSpeed and CrUX evidence.
• assets/templates/gsc-performance-report.md for Search Analytics exports.
• assets/templates/indexation-status-report.md for URL Inspection evidence.

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.
• Most integrations have no usage fee within quota. Cloud Natural Language requires billing and can incur charges; Google Ads requires account and developer-token access.
• Read references/search-currentness.md before diagnosing a named update, canonical change, Discover visibility, Google generative-AI reporting, platform properties, Preferred Sources, AMP, or crawler byte-limit issue.
• A named update's dates do not prove what caused an individual site's change. Wait one full week after rollout before comparing data, and separate Web, Image, Video, and News performance.
• Googlebot processes only the first 2MB of supported files and first 64MB of PDFs. Keep critical metadata and primary content before the cutoff.

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.
