Google Analytics 4

What it is.

Google hands you the Analytics tools free of charge, and on most B2B sites that covers the whole measurement layer: where a visit came from, what it did, and whether it converted.

Google publishes the exact point where free runs out. A standard property gives you 25 event parameters per event, 50 event-scoped custom dimensions, 30 key events, 100 audiences and 200 explorations per user, and Analytics 360 raises each one.

What you get.

  • Attribution from first touch to signup, so the channel argument has a source.
  • Up to 30 key events per property, which is the free ceiling on tracked conversions.
  • Audiences that push straight into Google Ads, capped at 100 on a standard property.
  • A BigQuery export on the free tier, so raw events can leave the interface entirely.
HOW TO USE IT

How to set it up.

1

Create the property, install the tag through Google Tag Manager, and confirm events in the DebugView panel before trusting anything.

2

Agree your event names in writing before you start tracking, because a renamed event splits its own history.

3

Mark your conversions as key events, and keep the list short since a standard property allows 30.

4

Add custom dimensions only for fields you report on weekly, since the free tier allows 50 event-scoped ones.

5

Turn on the BigQuery export on day one, because it only holds data from the day it was enabled.

6

Build reporting in Looker Studio and leave Explorations for ad hoc questions, since exploration counts are capped.

Use cases

Channel argument with a source

Pull the path from first touch to signup before the next budget conversation.

Key event ceiling

Map your conversions against the free property's limit so nothing important goes untracked.

Audience push to ads

Build the audience once and send it to the ad platforms from the same property.

Best for

Standard funnel reporting

Traffic source through to signup, for a site with a handful of conversion points. The free tier covers this with room to spare.

Feeding audiences to Google Ads

Audiences built on site behavior push straight into Ads, which is the cheapest retargeting setup available.

Getting raw data out

The BigQuery export on the free tier means your event data can live somewhere you control, joined to CRM records.

Questions about Analytics & Attribution

Do you need product analytics as well as GA4?
What should you agree before tracking anything?
Before you start
  • A tag manager container, or a developer who can place the tag.
  • An agreed list of event names before tracking starts.
Strengths
  • Google gives the tools free of charge, including a BigQuery export that used to be a paid-tier feature.
  • Every limit that separates free from paid is published, so you can plan against a number instead of a guess.
  • Audiences flow into Google Ads without a connector, which no third-party analytics tool can match.
Limitations
  • A standard property allows 30 key events, so a product with many tracked actions runs out of conversion slots.
  • Event-scoped custom dimensions are capped at 50, and deleting one does not recover the history under it.
  • The BigQuery export starts collecting the day you enable it, so a late setup means a permanent gap.
Skip this if
  • You already run a warehouse-first analytics stack and have no reason to add another tag.
Ideal for
  • Growth marketers
  • RevOps
  • Founders
