Stealth is a revenue monitor for publishers and networks that sell ads through Google Ad Manager (GAM). It reads your GAM reports every hour, compares each ad unit and each client with its own normal, and tells you when an ad unit stops serving, a client loses traffic or fill, or revenue drifts down. You see the problem in the dashboard and receive it by email, in the app and, if you want, in your own systems through webhooks.

How it works

  1. You connect your Google Ad Manager account. Stealth asks for access to read reports and never changes anything in your account.
  2. Stealth loads the last 28 days of history and, from then on, reads new data every hour.
  3. For every ad unit and client, Stealth learns what is normal for that hour of that weekday, based on the previous weeks.
  4. When the real numbers fall far enough below normal, and the rest of your portfolio did not fall the same way, Stealth opens an incident, estimates how much revenue is being lost and alerts your team.
  5. When the numbers return to normal, the incident is resolved and you are told that too.

Who it is for

  • Publishers with their own Google Ad Manager network who want to know, within hours, when an ad unit breaks.
  • Networks and partners that manage child publishers through Multiple Customer Management (MCM), who need to watch many clients at once and know which one to look at first.
  • Ad operations and monetization teams who today find revenue drops days later, in a spreadsheet.

What Stealth reads from Google Ad Manager

  • The list of networks your Google account can access (name and code).
  • Performance reports per ad unit: date, hour, ad unit name and code, child publisher, impressions, unfilled impressions, requests and revenue.
  • Daily revenue per demand source, used to explain drops.
  • The email address of the Google account that connected.

What Stealth never does

  • It never changes orders, line items, ad units, inventory or any setting in your Google Ad Manager account.
  • It never collects personal data about the visitors of your sites or apps.
  • It never reads Gmail, contacts or files.
  • It never sells your data, uses it for advertising or uses it to train AI models.
Stealth monitors. It does not fix the ad unit for you. Each alert tells you what broke, where and how much it costs, so your team can act on the right thing first.
