While analyzing your connected TV (CTV) campaign within Display & Video 360, you want to find the total number of engaged users. What report should you use?

The Reach Overlap report (part of DV360’s Unique Reach reporting tools) is designed to show how unique users cross over between different devices, campaigns, or channels. When evaluating Connected TV (CTV) environments, tracking “engaged users” means looking at the specific total of unique, unduplicated individuals who interacted with or saw your ads across devices.

Furthermore, DV360’s reach metrics specifically account for Co-Viewing in CTV reporting (when multiple unique people are sitting on a couch watching a connected television screen together), allowing you to accurately capture the true scale of engaged unique users.

Why the other options are incorrect:
Audience Composition report: This report breaks down the demographic makeup (age, gender) of the people you reached as a percentage of your overall audience, rather than giving you raw totals of unique engaged users across your CTV media mix.

Floodlight report: While Floodlight measures conversions and post-click/post-view actions on a website, CTV ads are primarily awareness-driven and served on TVs where users cannot directly click a tracking pixel, making a pure Floodlight report insufficient for capturing broad CTV user reach.

Inventory Availability report: This is a pre-campaign planning report used to see how many potential impressions are available to bid on based on your targeting parameters; it does not show post-campaign performance or actual unique users engaged.
