Google recently introduced a new Video Campaigns report in Google Analytics. This enhancement will give advertisers more insights into the performance of their YouTube TrueView ads that are managed through AdWords for Video campaigns.
The new report rolled out in Analytics accounts last week and can be found in the AdWords section under the Acquisition menu.
The report includes TrueView-specific metrics like Paid Views, Cost Per View, and Website Clicks and metric groups such as Engagement, for insights on how users engage with both a video and the corresponding website. The report can be segmented by Ad Content or Video.
The AdWords and Analytics accounts will need to be linked and auto-tagging needs to be activated in AdWords for the data to be available in Analytics.
For additional details see this Google Analytics blog post.
