Each ad unit has its own page that answers one question: is this ad unit fine, and if not, why. It brings together the open incidents and the Health findings that reach the ad unit, and shows its last 28 days and last 48 hours next to what is usual.

How it works

Opening the page

Click an ad unit’s name in any of these places:
  • The Ad Units table on a client page.
  • The ad unit in the header of an incident page.
  • The Ad Units table on an Opportunities item.
  • Affected Ad Units on a Health finding.
Back returns to the page you came from. When the page was opened from somewhere else, Back goes to the ad unit’s client.

What reaches the ad unit

A problem reaches the ad unit when:
  • It is about the ad unit itself, its client or its whole network.
  • It is about a line item that targets the ad unit.
  • It is about a header bidding set of the network. Header bidding sets serve every ad unit of the network, so the problem shows on every ad unit page.
  • It is about a site and the network has only one site. When the network has several sites, site problems do not show on ad unit pages, because Google Ad Manager does not tie a site to its ad units. Find them on the Health screen.
Problems that come from somewhere else say where: From the client, From the site, From the line item, From the header bidding set or From the network.

Site or Google Ad Manager

When an incident on the ad unit says so, the page tells the two cases apart:
  • Requests stopped: the page no longer calls this unit. The ad unit stopped receiving ad requests. The cause is usually on the site (a removed or broken tag), not in Google Ad Manager (GAM).
  • Requests normal, no demand. Requests keep arriving, but no ad is served. The cause is on the demand side, in GAM.

What you see

The header shows the ad unit’s name, its client, network, status in GAM and format, and Open in Ad Manager.
  • State: the severity of the worst open problem and one sentence: one of the two above, how many open problems reach the ad unit, or that nothing is open and when the checks ran today.
  • Open Problems: incidents first, then Health findings, each with its impact and a link to its own page. The card does not show when nothing is open.
  • Checks: the four Health groups for this ad unit (Delivery, Demand, Direct campaigns and Authorization), each with its open problems, OK, Not checked or Not checkable. See Health.
  • Daily Revenue against Usual: the last 28 complete days, each against the usual value for the same weekday (the median of the 4 previous weeks, when at least 3 of them have data). Switch between Revenue, Requests and Impressions. Days without data are left blank, never shown as zero. An ad unit with no request in the period says No requests in the last 28 days.
  • Requests per Hour against a Week Before: the last 48 hours of requests against the same hours 7 days earlier. These requests are approximate: served impressions plus unfilled impressions.
The footer shows when the ad unit was first seen, its last request and when its status was last read from GAM. Amounts are in the network’s currency.

FAQ

A problem on the client, such as a demand channel that stopped, reaches every ad unit of that client. It shows From the client and links to the finding.
Hourly data counts served and unfilled impressions, which is close to, but not exactly, the requests Google Ad Manager reports for the day.
