Analyse Your Marketing Data in the Advertising Section

Objective

This SOP helps you use the Advertising section in Google Analytics 4 to assess marketing performance across paid, organic, and publisher channels. You’ll learn how to analyze campaign outcomes, evaluate attribution models, and understand customer journeys, all critical for informed budget allocation and ad optimization.

Overview

This SOP covers:

  1. What the Advertising section includes
  2. Key report types and their use cases
  3. How to navigate the section step by step
  4. How to interpret attribution insights
  5. Common business questions answered by this data

Step 1: Access the Advertising Section in GA4

To begin:

  • Open your GA4 property
  • Navigate to Advertising from the left-hand navigation menu

This section provides reporting features specifically for properties linked with advertising tools like Google Ads or publisher platforms.

You’ll find detailed data on:

  • Conversion performance
  • Attribution paths
  • Campaign-level breakdowns
  • Publisher monetisation

Step 2: Use the Advertising Snapshot

The Advertising snapshot offers a high-level summary of your campaigns and touchpoints.

Use this to answer questions like:

  • How many conversions did each campaign drive?
  • What role did organic search, referrals, or ads play?
  • How long did it take users to convert?

Look for the “Key events by Primary channel group” card to see which channels are driving the most conversions.

Step 3: Dive into the All Channels Report

Click View all channels from the snapshot or go directly to the All Channels report.

Here, you’ll find:

  • Credit distribution per marketing channel over time
  • Visuals like line charts and bar graphs
  • Controls to adjust date range, key events, and apply filters

Step 4: Evaluate Key Events by Campaign

Switch the report dimension from Channel Group to Campaign.

This allows you to:

  • Analyze specific ad campaign performance
  • Focus on selected key events (e.g., Purchases)
  • Spot high or under-performing campaigns

Filter by different key events to narrow your view.

Step 5: Understand Attribution Paths

Go to the Attribution Paths report to see the customer journey across touchpoints.

This includes:

  • Sequence of ad clicks, referrals, and searches
  • What came early, mid, or late in the conversion path
  • The time delay between first interaction and purchase

Use this to refine your touchpoint strategy and conversion timing analysis.

Step 6: Compare Attribution Models

Navigate to the Attribution Models report.

By default, GA4 uses data-driven attribution—a machine learning-based model tailored to your conversion paths. You can compare it against:

  • Last-click attribution
  • First-click attribution
  • Linear, Time-decay, and Position-based models

This helps you determine how different attribution logic impacts campaign valuation.

Step 7: Use Planning and Publisher Ads Reports (If Applicable)

Planning Reports

  • Evaluate past performance across channels
  • Get ideas for new bidding strategies
  • Identify events that can be used as biddable conversions

Publisher Ads Report

  • Understand how your display ads are performing on your site/app
  • Access ad exposure and revenue metrics

Step 8: Apply to Business Strategy

Use the Advertising section to answer critical business questions such as:

  • What campaigns are working, and which channels drive revenue?
  • How do my ad interactions contribute to purchases?
  • Which campaigns provide the best ROAS?
  • How can I measure attribution across touchpoints?
  • Where should I invest more budget for higher conversions?

Scenario Example:
As a marketing manager, evaluate how various campaigns performed year-to-date in driving purchases using the reports outlined above. Filter by campaign, review ROAS, and reallocate spend based on conversion efficiency.
