GA4 Analytics Toolkit (Nexus Edition)

Multi-property version supporting dynamic discovery of GA4 properties and Search Console sites.

Setup

Install dependencies:

cd scripts && npm install

Configure credentials by setting the environment variable:

export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json

Optional configuration:

GA4_DEFAULT_DATE_RANGE=30d

Prerequisites:

• A Google Cloud project with the Analytics Data API, Analytics Admin API, Search Console API, and Indexing API enabled

• A service account with access to your GA4 properties and Search Console sites

• Service account must be added as Viewer to GA4 properties and have access to Search Console sites

Quick Start

First, discover available properties:

import { listGa4Properties, listSearchConsoleSites, siteOverview } from './scripts/src/index.js';

// List all accessible GA4 properties
const properties = await listGa4Properties();
console.log(properties);
// [{ propertyId: '123456789', displayName: 'My Site', accountId: '...' }, ...]

// List all accessible Search Console sites
const sites = await listSearchConsoleSites();
console.log(sites);
// [{ siteUrl: 'https://example.com', permissionLevel: 'siteFullUser' }, ...]

// Get overview for a specific property
const overview = await siteOverview('123456789', '30d');

Quick Reference

Execute functions by importing from scripts/src/index.ts:

import { 
  listGa4Properties, 
  listSearchConsoleSites,
  siteOverview, 
  searchConsoleOverview 
} from './scripts/src/index.js';

// List properties first
const properties = await listGa4Properties();

// Then query specific property
const overview = await siteOverview(properties[0].propertyId, '30d');

Or run directly with tsx:

npx tsx scripts/src/index.ts

Workflow Pattern

Every analysis follows three phases:

1. Discover

List available GA4 properties and Search Console sites to identify targets.

2. Analyze

Run API functions with specific property IDs and site URLs. Each call hits the Google APIs and returns structured data.

3. Auto-Save

All results automatically save as timestamped JSON files to results/{category}/. File naming pattern: YYYYMMDD_HHMMSS__operation__extra_info.json

4. Summarize

After analysis, read the saved JSON files and create a markdown summary in results/summaries/ with data tables, trends, and recommendations.

Discovery Functions

GA4 Property Discovery

const properties = await listGa4Properties();
// Returns: [{ propertyId: '123456789', displayName: 'My Site', accountId: '...' }, ...]

Search Console Site Discovery

const sites = await listSearchConsoleSites();
// Returns: [{ siteUrl: 'sc-domain:example.com', permissionLevel: 'siteFullUser' }, ...]

Utility

Individual API Functions

For granular control, import specific functions from the API modules:

import { runReport, getPageViews, getTopQueries } from './scripts/src/index.js';

// Run custom report for specific property
const report = await runReport({
  propertyId: '123456789',
  dimensions: ['pagePath'],
  metrics: ['screenPageViews'],
  dateRange: '7d'
});

// Get Search Console data for specific site
const queries = await getTopQueries('https://example.com', '30d');

Date Ranges

All functions accept flexible date range formats:

Default is "30d" (configurable via GA4_DEFAULT_DATE_RANGE env var).

Results Storage

Results auto-save to results/ with this structure:

results/
├── reports/          # GA4 standard reports
├── realtime/         # Real-time snapshots
├── searchconsole/    # Search Console data
├── indexing/         # Indexing API results
└── summaries/        # Human-readable markdown summaries

Managing Results

import { listResults, loadResult, getLatestResult } from './scripts/src/index.js';

// List recent results
const files = listResults('reports', 10);

// Load a specific result
const data = loadResult(files[0]);

// Get most recent result for an operation
const latest = getLatestResult('reports', 'site_overview');

Common Dimensions and Metrics

Dimensions

pagePath, pageTitle, sessionSource, sessionMedium, country, deviceCategory, browser, date, eventName, landingPage, newVsReturning

Metrics

screenPageViews, activeUsers, sessions, newUsers, bounceRate, averageSessionDuration, engagementRate, conversions, totalRevenue, eventCount

Tips

1. Discover first — Always start with listGa4Properties() and listSearchConsoleSites() to see what's available

2. Multi-property — This toolkit supports analyzing multiple GA4 properties and Search Console sites without reconfiguration

3. Specify date ranges — "last 7 days" or "last 90 days" gives different insights than the default 30 days

4. Request summaries — After pulling data, ask for a markdown summary with tables and insights

5. Compare periods — Use compareDateRanges() to spot trends (this month vs last month)

6. Check real-time data — liveSnapshot() shows who's on the site right now

7. Combine GA4 + Search Console — Traffic data plus search query data gives the full picture
