How to receive Omerlo Ad Events in Google Analytics 4 using Google Tag Manager

Step 1 - Configure Google Tag Manager custom variables

GTM will require a few custom variable definitions to be able to forward important informations to GA4.

Under Variables, User-Defined Variables, configure these variables:

• DLV - adClickthroughUrl

  • Type: Data Layer

  • Name: adClickthroughUrl

• DLV - adCreativeId

  • Type: Data Layer

  • Name: adCreativeId

• DLV - adFormat

  • Type: Data Layer

  • Name: adFormat

• DLV - adMediaId

  • Type: Data Layer

  • Name: adMediaId

• Ad Event Settings

  • Type: Google Tag: Event Settings

  • Event Parameters:

    • Parameter: adCreativeId, Value: DLV - adCreativeId

    • Parameter: adClickthroughUrl, Value: DLV - adClickthroughUrl

    • Parameter: adFormat, Value: DLV - adFormat

    • Parameter: adMediaId, Value: DLV - adMediaId

Step 2- Configure Google Tag Manager custom events

Now that our Data Layer variables are created, let's create our GA4 Event Tags to forward our custom events received in GTM to GA4.

Under Tags, add the following tags:

• adImpression

  • Type: Google Analytics: GA4 Event

  • Set the measurement ID to you GA4 container using a variable or by entering it manually.

  • Event name: adImpression

  • Event Parameter: Select the Event Settings Variable created at Step 1

  • Add the following trigger:

    • Custom Event: adImpression

• adClick

  • Type: Google Analytics: GA4 Event

  • Set the measurement ID to you GA4 container using a variable or by entering it manually.

  • Event name: adClick

  • Event Parameter: Select the Event Settings Variable created at Step 1

  • Add the following trigger:

    • Custom Event: adClick

Step 3 - Configure Custom Definitions in GA4

Now that GTM forwards our Omerlo Ad Events to GA4, let's configure the parameters in GA4 to allow analytics to include the parameter values in reports.

Under Admin, Custom Definitions, add the following Custom Dimensions:

• ad_clickthrough_url:

  • Scope: Event

  • Event parameter: adClickthroughUrl

• ad_creative_id:

  • Scope: Event

  • Event parameter: adCreativeId

• ad_format:

  • Scope: Event

  • Event parameter: adFormat

• ad_media_id

  • Scope: Event

  • Event parameter: adMediaId

Now that our events are correctly configured in GTM and GA4, Omerlo Ad Events should show in Event Dashboard and should be available in reports.
