What is Google Ad Manager? The system that places ads on you.

Google Ad Manager explained simply: how this ad-serving system decides which ads you see on Indian sites, what signals it can use, and the privacy questions.

The simple answer

Google Ad Manager, once known as DoubleClick, is a system publishers use to serve and manage ads. When you open a page, it helps decide which ad fills each slot, often through an automated auction in the background.

To choose ads, the system can use signals like your interests, device and past activity. Most people never notice this layer, but it is a core part of how the ad-funded web works.
