In Google Analytics, the source/medium report provides information about the sources and mediums that are driving traffic to a website.
The source refers to the place where the traffic is coming from, such as a search engine, a social media platform, or a referral website.
The medium refers to the type of link that was clicked to access the site, such as organic search, referral, or email.
The source/medium report allows users to see which sources and mediums are providing the most traffic, and to compare the performance of different sources and mediums.
This can provide valuable insights for understanding the effectiveness of different traffic sources and for identifying opportunities to improve the performance of the website.
