What you see
The title is the type of the incident. Under it are the scope (the ad unit, or the whole client), the client and the network, with the severity and the status. At the top right:- Mark as seen, on an open incident, as in Incidents.
- Copy summary for support copies a plain text summary to paste in a ticket or a chat. It has the scope, the start, the estimated loss, the reading, the possible causes and the link.
- Open in Ad Manager opens the ad unit, or the network when the incident covers the whole client.
Key numbers
What Happened
A chart of what the ad unit or the client delivered (Observed) against what was normal for the same hour in the previous weeks (Expected). It starts 24 hours before the incident and goes on until 24 hours after it was resolved, or until now. Daily types compare each day with the same weekday of previous weeks. The metric follows the type: requests per hour for the traffic types, fill rate per hour for the fill types, revenue per day for the two revenue types. A line marks the start of the incident, and a marker shows each change made in Google Ad Manager (GAM) in that period. The Expected line does not discount the market, but the estimated loss does, so the gap in the chart can be larger than the loss. When there is not enough history, the chart says so instead of drawing a line.Market or Client
Tells whether the drop follows the market or belongs to this client. For revenue types, a table compares each demand source with what was expected and shows how much of its fall is the market and how much is this client’s own. For the other types, one sentence states the rule that opened the incident, such as that the rest of the client kept its traffic, so the drop is specific to the ad unit. When there is not enough demand history, the card says so.Possible Causes
A short list, up to 5 causes, ranked by how likely they are. Each one shows its evidence: for a change in GAM, the fields before and after, who made it and when, with View change and Open in Ad Manager. The types are:- GAM change: a change to one of the incident’s own ad units in the 24 hours before it started, or in its first hour.
- Demand source: the source whose own revenue fell the most, for revenue types.
- Traffic: requests stopped arriving, which usually points to the site.
Other signals in the network
A collapsed block under the possible causes, with a count such as 3 other signals in the network. It lists, newest first and up to 10, the changes made on the same network that are not on the incident’s ad units, with View in Activity to see them all. While the incident is open, it also lists the line items of the network flagged as not delivering, ending soon below goal, behind pace or missing creatives. These cover the whole network, not only this ad unit, and are never possible causes.Next Steps
A short checklist, up to 5 lines, for the type of the incident, plus one line for the main possible cause, such as reviewing a change and who made it. The last line asks the team to record the verdict.Verdict
Where the team records what really caused the incident, to compare with Stealth’s reading. Any member of the organization can set it or change it.
Choose Save verdict. The page then shows who recorded it and when. Clear verdict removes it. The verdict also appears in Incidents and in the client page, next to the reading. Each change to a verdict is recorded in the Stealth tab of Activity.
Older types
Incidents of types from earlier versions of the detection, such as Revenue zeroed, show only the header, the key numbers and the verdict.FAQ
Is a possible cause the real cause?
Is a possible cause the real cause?
No. It is a coincidence in time, found in data Stealth already reads. Use it as the first place to look, and record the verdict once you know.
Why is a change on the network not listed as a possible cause?
Why is a change on the network not listed as a possible cause?
Stealth does not know which ad units a line item, an order or another network change reaches. To keep the list trustworthy, only changes to the incident’s own ad units are ranked. The rest is under Other signals in the network.
Why are there no line items on a resolved incident?
Why are there no line items on a resolved incident?
Line item signals describe the network now, not when the incident happened, so they appear only while the incident is open.
Does Stealth change anything in Google Ad Manager?
Does Stealth change anything in Google Ad Manager?
No. Stealth only reads. The links open Google Ad Manager so you can check and fix things yourself.
