UnderstandingYour MarketingData

Why the numbers never quite match and how to use each platform correctly.

A plain-English guide for business owners and marketing teams.

The Golden Rule

No two platforms will ever report the same number. The goal is not to find one matching number — it is to understand what each platform tells you and use it for the right purpose.

GA4 is a behaviour and traffic analysis tool

GA4 is a behaviour and traffic analysis tool. It tracks how people move around your website — where they come from, what they look at, how long they stay, and where they drop off.

What GA4 is good for

  • Understanding which channels drive the most engaged traffic
  • Spotting trends over time (is organic traffic growing?)
  • Analysing user journeys and funnel drop-off points
  • Comparing content or landing page performance
  • Identifying peak traffic periods and audience demographics

How GA4 attribution actually works

This is one of the most misunderstood aspects of GA4. It does not use a single attribution model — it uses different models depending on which report you're viewing.

Three Scopes, Two Different Models

User scope (prefix "First user...") → Last non-direct click — fixed

Session scope (prefix "Session...") → Last non-direct click — fixed

Event scope (no prefix) → Data-Driven Attribution — configurable

Cookie Deprecation

Safari and Firefox block third-party tracking. Chrome has reduced cross-site tracking. An increasing portion of GA4 data is modelled (estimated), not measured. Excellent for trends — unreliable for exact counts.

What GA4 is NOT for

  • Do not use as your source of truth for revenue or conversions
  • Do not try to reconcile GA4 numbers with your CRM
  • Do not use to evaluate campaign ROI in isolation
