GA4 Analytics Toolkit

Setup

Install dependencies:

cd scripts && npm install

Configure credentials by creating a .env file in the project root:

GA4_PROPERTY_ID=123456789
GA4_CLIENT_EMAIL=service-account@project.iam.gserviceaccount.com
GA4_PRIVATE_KEY="-----BEGIN PRIVATE KEY-----\n...\n-----END PRIVATE KEY-----\n"
SEARCH_CONSOLE_SITE_URL=https://your-domain.com
GA4_DEFAULT_DATE_RANGE=30d

Prerequisites: A Google Cloud project with the Analytics Data API, Search Console API, and Indexing API enabled. A service account with access to your GA4 property and Search Console.

Quick Start

User says	Function to call
"Show me site traffic for the last 30 days"	siteOverview("30d")
"What are my top search queries?"	searchConsoleOverview("30d")
"Who's on the site right now?"	liveSnapshot()
"Reindex these URLs"	reindexUrls(["https://example.com/page1", ...])
"Compare this month vs last month"	compareDateRanges({startDate: "30daysAgo", endDate: "today"}, {startDate: "60daysAgo", endDate: "31daysAgo"})
"What pages get the most traffic?"	contentPerformance("30d")

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

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

const overview = await siteOverview('30d');

Or run directly with tsx:

npx tsx scripts/src/index.ts

Workflow Pattern

Every analysis follows three phases:

1. Analyze

Run API functions. Each call hits the Google APIs and returns structured data.

2. Auto-Save

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

3. Summarize

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

High-Level Functions

GA4 Analytics

Function	Purpose	What it gathers
siteOverview(dateRange?)	Comprehensive site snapshot	Page views, traffic sources, demographics, events
trafficAnalysis(dateRange?)	Traffic deep-dive	Sources, sessions by source/medium, new vs returning
contentPerformance(dateRange?)	Top pages analysis	Page views, landing pages, exit pages
userBehavior(dateRange?)	Engagement patterns	Demographics, events, daily engagement metrics
compareDateRanges(range1, range2)	Period comparison	Side-by-side metrics for two date ranges
liveSnapshot()	Real-time data	Active users, current pages, current events

Search Console

Function	Purpose	What it gathers
searchConsoleOverview(dateRange?)	SEO snapshot	Top queries, pages, device, country breakdown
keywordAnalysis(dateRange?)	Keyword deep-dive	Queries with device breakdown
seoPagePerformance(dateRange?)	Page SEO metrics	Top pages by clicks, country breakdown

Indexing

Function	Purpose
reindexUrls(urls)	Request re-indexing for multiple URLs
checkIndexStatus(urls)	Check if URLs are indexed

Utility

Function	Purpose
getAvailableFields()	List all available GA4 dimensions and metrics

Individual API Functions

For granular control, import specific functions from the API modules. See references/api-reference.md for the complete list of 30+ API functions with parameters, types, and examples.

Date Ranges

All functions accept flexible date range formats:

Format	Example	Description
Shorthand	"7d", "30d", "90d"	Days ago to today
Explicit	{startDate: "2024-01-01", endDate: "2024-01-31"}	Specific dates
GA4 relative	{startDate: "30daysAgo", endDate: "today"}	GA4 relative format

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

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. Specify date ranges — "last 7 days" or "last 90 days" gives different insights than the default 30 days
2. Request summaries — After pulling data, ask for a markdown summary with tables and insights
3. Compare periods — Use compareDateRanges() to spot trends (this month vs last month)
4. Check real-time data — liveSnapshot() shows who's on the site right now
5. Combine GA4 + Search Console — Traffic data plus search query data gives the full picture
