Which dimension should you use to determine which sources, such as "organic search" or "referral," are driving users to your website?

Question: Which dimension should you use to determine which sources, such as "organic search" or "referral," are driving users to your website?

• You should use Session primary channel group (Default Channel Group).
• You should use Page title and screen class.
• You should use Session source / medium.
• You should use Google Ads campaign.

Explanation

Session primary channel group reports the default channel grouping that brought traffic to a website or app during a session. It classifies traffic into channels such as Organic Search, Referral, Paid Search, and Direct. This dimension is useful when the goal is to understand the broad traffic sources driving users. It provides a channel-level view rather than a page, campaign-only, or screen-level view.

Why the other options are incorrect

Google Ads campaign reports Google Ads campaign traffic, not all traffic sources.

Session source / medium gives more granular source and medium details, but it is not the default channel grouping dimension for sources such as organic search or referral.

Page title and screen class identifies content viewed, not how users arrived.
