Campaign Manager 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 Campaign Manager (by Advertiser) extraction and choose a week, month or quarter as the time granularity.
The new Cumulative Reach report returns, for every day, the users reached for the first time in the week, month or quarter that day belongs to. Campaign Manager 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, Viewable Impression, Click and Total Reach.
- Breakdowns by advertiser, campaign, placement, site, country and platform type. Campaign Manager 360 reports incremental reach by campaign, placement and site name, not ID, so campaigns, placements or sites with the same name share a row.
- A week, month or quarter as the period, each fetched as one Campaign Manager 360 report per advertiser. A quarter is the longest period, because Campaign Manager 360 caps an incremental reach report at 93 days. History goes back at most 2 years.
How to read the numbers
- Add up the days of one period to get its reach. On small breakdowns the sum can be up to a few percent lower than the period's reach. Adding days across two periods can count the same users twice.
- Reach does not add up across campaigns, placements or other breakdowns either, because one user can see several of them. For a campaign or advertiser total, build the extract at that level.
- Campaign Manager 360 can take up to 3 days to make reach available, so the last 3 days can still change. Days without a Campaign Manager 360 estimate are 0.
