The Traffic acquisition report is a pre-made detail report that's designed to help you understand where your website and app visitors are coming from. It specifically shows where new and returning users come from. It differs from the User acquisition report, which shows where new users come from.
How to find where your users are coming from using Acquisition Reports in Google Analytics 4
Traffic source dimensions
The Traffic acquisition report provides cross-channel traffic source dimensions, a special set of product-agnostic dimensions that help you dig into how you acquire users.
These cross-channel traffic source dimensions provide information across organic and paid traffic sources, google-paid sources and third-party paid sources, buying platforms (e.g., Google Ads, Display & Video 360, Search Ads 360), and publisher or inventory sources (e.g., Google Search, YouTube).

Where the data comes from
You have the option to collect traffic-source data by manually tagging your destination URLs, or by creating integrations between Analytics and your ad platforms (e.g., Google Ads, Search Ads 360, or Display & Video 360) and using the auto-tagging feature available with those integrations.
View data for one traffic source
To find data for one traffic source, you can search for the traffic source in the search bar above the table. For example, to view organic Google Search traffic, search "google / organic" and press Enter.
