Essential steps

The methodology that delivers real results

01

GA4 property setup

First step: a correctly configured property.

  • Create a GA4 property in analytics.google.com
  • Add a Data Stream for the site (Web)
  • Copy the Measurement ID (G-XXXXXXXXXX)
  • Install through Google Tag Manager, NOT hardcoded in HTML
02

Enhanced Measurement switched on

Automatic tracking for the most common actions.

  • Page views, Scrolls (90% depth)
  • Outbound clicks, Site search
  • Video engagement (YouTube embeds)
  • File downloads, Form interactions
03

Custom conversions (the part that matters most)

You mark as a conversion everything that represents value for the business.

  • Contact form completed → event form_submit
  • Phone number click → event click (phone_number)
  • Purchase → event purchase (value, currency, items)
  • Guide download → event file_download
04

The reports you actually need

You know which reports to look at and which to ignore.

  • Acquisition Report: where users come from + conversion rate per channel
  • Engagement Rate: benchmark 40-60% blog, 60-80% product
  • Conversion Paths: how many touchpoints before conversion
  • Cohort Analysis: how users behave over time
05

Integrations you cannot skip

GA4 alone is limited: you integrate it with the rest of the ecosystem.

  • Google Search Console: organic queries
  • Google Ads: import conversions for Smart Bidding
  • BigQuery: export raw data for advanced analysis
  • CRM (HubSpot/Salesforce): connect offline conversions
06

GDPR and Consent Mode V2

Mandatory in the EU since 2024, without it, you lose data.

  • Compliant cookie banner: Cookiebot, CookieYes or custom
  • Consent Mode V2 configured in GTM
  • Google Signals enabled (for demographic data)
  • Data Retention set to 14 months (maximum free tier in GA4)

Frequently asked questions

GA4 is ?

Yes, Google Analytics 4 is completely free. Google Analytics 360 (the Enterprise version) has a cost, but for SMEs in Romania the free GA4 is more than enough.

How do I know the tracking is set up correctly?

Go to GA4 > Reports > Realtime and perform an action on the site (fill in a form, click a button). If you see the event within 30 seconds: tracking is working correctly.

What do I actually do with the GA4 data?

The data is used for: optimising paid campaigns (importing conversions into Google Ads), understanding user behaviour (which pages work), identifying problems (where users drop out of the funnel) and making budget decisions.
