Activity answers two questions when something moves: what changed in Google Ad Manager, and who changed a setting in Stealth. It has two tabs, Google Ad Manager and Stealth, and keeps 90 days of both. Open it from the sidebar, under Alerts. Every change Stealth read on your direct line items (standard and sponsorship), orders and ad units. Stealth reads each network every hour and compares it with the previous read. Several changes by the same user to the same order within a few minutes show as one row: the order under Item and, under What changed, a count such as 12 changes to 8 items. Click the row to see each change.

Filters

Search by item name, order name or Google Ad Manager ID, and filter by period (24 hours, 7, 30 or 90 days), network, field (status, dates, goal, budget and price, targeting and others) and who made the change. Only may be related keeps the changes followed by an incident on the same network within 24 hours. The filters stay in the address, so you can send the link to someone on your team.

Sort, column width and pages

Click a column title to sort by it; click again to reverse the order. An arrow next to the title shows the direction. When, Network, Item, Source and Changed by can be sorted; the list opens newest first. Sorted by any column other than When, changes no longer group into one row per order. Drag the line between two column titles to make a column wider or narrower. With the keyboard, focus that line and use the arrow keys. Your widths stay in this browser; double-click the line to go back to the default widths. The list shows 50 changes per page. Pick a page under the list; the page, the sort and the filters stay in the address.

Who made the change

Changed by is the name of the Google Ad Manager user, with their email under it so two users with the same name can be told apart. It may be a login shared by more than one person. It can also read:
  • Integration: the change came from an app or service connected to Google Ad Manager.
  • Used in N networks: the same user name appears in several networks of your organization, probably a shared or agency login.
  • GAM automatic: Google Ad Manager recorded no user, usually Google Ad Manager itself, such as a line item that turns ready once its creative is approved.
  • Author not available: the user connected to Stealth cannot see the change history of that network.

Change detail

Click a row to open the change. It shows each field before and after, impressions per hour from 3 days before to 3 days after the change, the other changes to the same item, who and when, the item’s current state in Google Ad Manager and the incidents that started in the next 24 hours. May be related carries the Estimated badge: it is a coincidence in time, not a proven cause. Open in Google Ad Manager opens an ad unit directly; for a line item or an order it opens the network, with the item’s ID ready to copy. Copy summary for support copies a plain text summary of the change to paste in a ticket or a chat.

Networks Google Ad Manager does not let Stealth read

When Google Ad Manager refuses to show a network’s changes, the tab shows a short notice, such as 10 networks do not allow reading changes. How to fix opens the networks grouped by reason, each with what to do:
  • API access is turned off: an admin of the network signs in to Google Ad Manager and, in Admin > Global settings > Network settings, turns on API access, confirms the API terms and clicks Save. See Turn on API access in Google’s help.
  • The connected Google account is not a user of the network: an admin of the network adds the Google account that reads it, named below the network, in Admin > Access & authorization > Users. See Add and edit users in Google’s help. Owners and admins can also choose Connect another Google account, or Stop reading this network to turn the network off (its history is kept). With more than one Google account connected, the networks are split by the account that reads them, each with its own steps.
Stealth tries again every hour, so a network comes back on its own once it is fixed. On the Panel, Why? in the GAM Changes card opens this guide.

FAQ

Stealth keeps 90 days of changes in both tabs. A longer history will be available as an add-on.
Google does not publish links to line items and orders. Stealth opens your network in Google Ad Manager and shows the item’s ID, so you can paste it in the search.
