Summary
The User Acquisition Report provides the count of people who visited the site for the first time after the campaign. It sits under Reports, Acquisition, User acquisition in GA4 and uses First user dimensions with the New users metric. The Lift studies are Google Ads measurement tools and do not report website visits.

To see how many people visited the site for the first time after a video campaign, use the User Acquisition report in Google Analytics, which reports new users by the channel and source that first brought them in.
- Brand Lift
- User Acquisition Report
- Search Lift
- Conversion Lift
The correct answer is: User Acquisition Report
Key Takeaways
- – The User Acquisition report in Google Analytics shows how many people visited the site for the first time after a campaign, and which source brought them.
- – In GA4 the report sits under Reports, Acquisition, User acquisition, and uses First user dimensions with the New users metric.
- – User acquisition credits the first ever visit, while Traffic acquisition credits each session, so the two reports will not match and are not supposed to.
- – Brand Lift, Search Lift and Conversion Lift are YouTube study types inside Google Ads that measure attitude, search behaviour and conversion impact, not first-time website visits.
What is the difference between the User Acquisition and Traffic Acquisition reports in GA4?
User acquisition uses First user dimensions, so every session a person has is credited back to the channel that first brought them to the site. Traffic acquisition uses Session dimensions and credits each individual session to whatever brought that session in. If someone first arrives from YouTube and returns later through organic search, User acquisition still counts them under the video campaign while Traffic acquisition counts the second visit under organic.
Which metric in the User Acquisition report answers a first-time visitor question?
New users is the metric to read. It counts people whose first ever recorded session on the property happened during the date range you selected. Total users includes returning visitors, so reading Total users when the question asks about first-time visits will overstate the campaign’s reach.
Why can Brand Lift not answer how many people visited the site for the first time?
Brand Lift is a survey based study run in Google Ads. It measures shifts in ad recall, awareness and consideration between an exposed group and a control group. It reports survey responses and lifted users, not website sessions, so it cannot tell you anything about traffic landing on your site.
How do I isolate YouTube campaign traffic inside the User Acquisition report?
Change the primary dimension to First user source / medium or First user campaign, then look for youtube.com or your Google Ads campaign name. If your Google Ads account is linked to the GA4 property, campaign names flow in automatically. For anything not linked, add UTM parameters to your final URLs so the campaign appears cleanly instead of falling into referral or direct.
