Display & Video 360: new Cumulative Reach report, daily reach that adds up to the period
- Updated
- October 23, 2026
- Affected
- Cumulative Reach
- What to do
- No action required for existing reports. Add the Cumulative Reach report to your Google Display & Video 360 extraction and choose a week, month or quarter as the time granularity.
The new Cumulative Reach report returns, for every day, the people reached for the first time in the week, month or quarter that day belongs to. Display & Video 360 calculates these values with its own Unique Reach: Incremental metrics, so the days of a period add up to the reach of the whole period. One row is a day and the breakdown you select.
What you get
- Incremental Impression, Click, Total and Viewable Impression Reach, plus Incremental Impression and Total Reach (Co-Viewed), which also count people watching together on a connected TV.
- Breakdowns by partner, advertiser, campaign, insertion order, line item, creative, country and device type. Audience breakdowns are available to Display & Video 360 users allowed to report on audiences.
- A week, month or quarter as the period, with a selectable week start day and quarter start month.
How to read the numbers
- Add up the days of one period to get its reach. Adding days across two periods counts the same people twice.
- Reach does not add up across line items, creatives or other breakdowns either, because one person can see several of them. For a campaign or advertiser total, build the extract at that level.
- Display & Video 360 can take up to 3 days to settle reach, so the most recent days are refreshed by the following runs. Days without a Display & Video 360 estimate are 0.
