Google Analytics 4 (GA4) replaced Universal Analytics (UA) on July 1, 2023, ending years of the analytics system most digital marketers grew up with. Two years in, the majority of Indian businesses either have a poorly configured GA4 that they barely use, or they are misinterpreting the data because GA4 works fundamentally differently from UA. This guide covers the GA4 configuration, reports, and event tracking that give you genuinely actionable marketing insights — not just a dashboard full of numbers that do not inform decisions.
How GA4 Differs from Universal Analytics (and Why It Matters)
GA4 is an event-based model; UA was a session-based model. In UA, everything was measured in sessions (a group of interactions in a 30-minute window). In GA4, everything is an event — a page view is an event, a button click is an event, a conversion is an event. This fundamental difference changes how you interpret almost every metric. Key differences: GA4 sessions are calculated differently (a session does not restart when a new campaign source is detected mid-visit), Bounce Rate has been replaced by Engagement Rate (sessions with 10+ seconds duration, 1+ conversion events, or 2+ page views), Users in GA4 counts unique users differently than UA (using a probabilistic model that often shows lower numbers than UA for the same traffic), and conversions in GA4 are events that you mark as conversions — not Goals. These differences mean you cannot compare GA4 data to historical UA data apples-to-apples.
GA4 Configuration: The Setup That Most Businesses Miss
A default GA4 installation tracks very little useful information. The essential configuration steps that most businesses skip: Enable Enhanced Measurement correctly (scroll depth tracking, outbound link clicks, and file downloads are valuable; site search tracking requires configuration to work properly), configure Data Retention to 14 months (the default is 2 months — too short for year-over-year comparisons), link GA4 to Google Ads (for conversion import and audience sharing), link GA4 to Google Search Console (for organic keyword data in GA4 reports), set up Conversion Events (mark your most important events as conversions — form submissions, phone call clicks, purchase completions, WhatsApp button clicks), and configure Custom Dimensions for data that GA4 does not capture by default (user type, membership level, CRM status). Without this configuration, GA4 data is significantly less useful than it should be. AddMads' GA4 setup service covers all of these configurations.

The GA4 Reports That Actually Drive Marketing Decisions
GA4 has dozens of reports but most provide limited actionable value. The four reports that should drive your weekly marketing decisions: Traffic Acquisition (which channels are driving sessions and conversions — identify your best-performing channels and where budget should increase or decrease), Landing Page report (which pages drive the most sessions and engagement — improve underperforming landing pages for your key campaigns), Conversion Paths report (in Advertising → Attribution → Conversion Paths — shows the full journey from first touchpoint to conversion, resolving the attribution question across multiple marketing channels), and Search Console Integration report (which organic search queries drive traffic and conversions — directly informs your SEO content priorities). For e-commerce businesses, the Monetisation reports (Ecommerce Purchases, Purchase Journey, Checkout Journey) are additionally essential.
Custom Events and Conversions: Tracking What Matters for Your Business
GA4's power lies in its flexibility — you can track virtually any user interaction as an event and mark business-critical events as conversions. For Indian businesses, the most valuable custom events to implement: WhatsApp button clicks (a primary conversion action for many Indian businesses that GA4 does not track by default), phone number clicks (tel: links tracked as events), form submission success (separate from form view — only count when form is successfully submitted), video play events (for businesses using video as a key marketing tool), pricing page visits and time on page (intent signals for B2B businesses), and chatbot engagement events. Implement these via Google Tag Manager without touching your website code. Each additional conversion event gives GA4's AI attribution model more data to work with, improving the quality of insights in Conversion Paths and channel attribution reports.
GA4 Explorations: Building Custom Reports for Deeper Insights
GA4's standard reports cover common use cases. The Explorations section (the compass icon in the left navigation) is where advanced analysis happens. Free-form exploration lets you build custom tables and charts with any combination of dimensions and metrics. Path exploration shows the sequence of pages users visit — invaluable for identifying where users drop off in your conversion funnel. Funnel exploration lets you define a multi-step conversion funnel and see drop-off rates at each step, broken down by device, traffic source, or any other dimension. Segment overlap shows how different audience segments (e.g., paid traffic users vs. organic users vs. returning users) overlap and behave differently. For Indian businesses with meaningful website traffic (10,000+ monthly sessions), Explorations provide the granular insights that justify the analytics investment.
Key Takeaway
Google Analytics 4 properly configured and regularly analysed is the intelligence layer beneath every digital marketing decision — where to invest more budget, which content is working, where the conversion funnel is leaking, and which channel actually drives revenue (not just traffic). The businesses achieving the best marketing ROI are almost universally the ones that make decisions from data, not intuition. AddMads provides GA4 setup, custom event tracking, and ongoing analytics management for businesses that want data-driven marketing.
