What is Source Platform in Google Analytics 4 (GA4)?

In the detailed and dynamic world of Google Analytics 4 (GA4), understanding each dimension and how it influences your data analysis is crucial. The “Source Platform” dimension is particularly significant as it provides insights into the platforms where advertising and marketing activities are managed. This article explores the definition of the Source Platform, provides examples from both Google and non-Google platforms, and discusses how to populate this dimension using UTM parameters.

Definition

Source Platform in GA4 is a dimension that identifies the platform on which buying activities—such as managing budgets, setting targeting criteria—are conducted. This dimension helps analysts and marketers understand where and how the traffic to their websites is being generated and managed.

Examples of Source Platforms

Here are some platforms typically identified in GA4 as source platforms:

  • Google Ads: Traffic coming from Google Ads campaigns.
  • Manual: Traffic that does not originate from a specific media buying platform; includes direct traffic or traffic from manually tagged URLs.
  • SA360 (Search Ads 360): Traffic from Search Ads 360, a platform for managing search campaigns across various search engines.
  • SFMC (Salesforce Marketing Cloud): Traffic from campaigns managed via Salesforce Marketing Cloud.
  • Shopping Free Listings: Traffic from Google Merchant Center’s free listings.

Populating the Source Platform Dimension

UTM Parameters and Their Usage

To populate the Source Platform dimension effectively, it is essential to use UTM parameters. These parameters are appended to URLs to track where traffic originates from and through what medium it comes. The utm_source_platform parameter can be added to specify the platform managing the buying activity.

Basic Structure of UTM Parameters

A typical UTM-tagged URL might look like this:

https://www.example.com/?utm_source=google&utm_medium=cpc&utm_campaign=summer_sale&utm_source_platform=Google_Ads

In this URL:

  • utm_source=google indicates the source of the traffic.
  • utm_medium=cpc shows the medium (cost-per-click).
  • utm_campaign=summer_sale is the specific campaign.
  • utm_source_platform=Google_Ads specifies the platform used for the campaign.

Examples with Non-Google Platforms

LinkedIn Ads

https://www.yoursite.com/?utm_source=linkedin&utm_medium=social&utm_campaign=career_opportunities&utm_source_platform=LinkedIn_Campaign_Manager

This URL is used to track a recruitment campaign managed through LinkedIn’s Campaign Manager.

Facebook Ads

https://www.yoursite.com/?utm_source=facebook&utm_medium=social&utm_campaign=new_product_launch&utm_source_platform=FB_Ads_Manager

This URL would track traffic from a Facebook campaign promoting a new product, managed through Facebook Ads Manager.

Importance in Digital Marketing

Integration with Promotional Campaigns

By understanding which source platform is generating traffic, businesses can more accurately target their marketing efforts. For example, if data indicates that video content on Facebook is particularly effective, additional resources might be allocated to this channel.

Customization of Content and Offers

Insights from the Source Platform dimension allow marketers to tailor content and promotions specifically to the audiences on different platforms. This can enhance user engagement and conversion rates by aligning marketing messages with user expectations and platform norms.
