What report shows data segmented by channel?

The report that shows data segmented by channel is the Channels report. This report breaks down traffic sources into categories such as organic search, direct, social, referral, and paid search, allowing users to analyze how different marketing channels contribute to overall website performance. By viewing data in this segmented manner, marketers can evaluate the effectiveness of each channel in driving traffic, conversions, and user engagement.

In the case of the other options, while Source/Medium provides valuable insights into the specific sources of traffic and the mediums used (such as organic search from Google or paid ads from Facebook), it does not categorize this information into broader channel groupings. Segmentation is a method of dividing data into distinct and manageable parts based on certain criteria, but it doesn't specifically focus on channel performance as a standalone report. Attribution deals with understanding the value of different marketing channels over the customer journey, but it does not present data in the same straightforward segmented format by channel as the Channels report does.
