How RTB works
With real-time bidding, your network can receive and review pre-filtered inventory to establish and execute bids.
Review detailed developer documentation in the Authorized Buyers Real-Time Bidding (RTB) Protocol.
Once your account is set up, here's what happens:
1. Specify inventory to receive with pretargeting
Filtered bid requests are sent based on the pretargeting configuration. These requests specify targeting criteria, such as day parting, language, geographical region, and so forth. You can specify the maximum number of requests (queries per second) that your system can receive.
2. You receive pre-filtered ad call parameters
The following parameters are passed to your system:
- HTTP header with referrer URL (for branded sites) or site IDs (for anonymous sites)
- Targeting information, such as geo and vertical
- Truncated user IP address (IPV4 and IPV6)
- Encrypted user cookie ID
- Ad unit restrictions, such as restricted advertisers, creative types or product verticals
3. Your system analyzes the ad call, layers additional targeting data, and submits your bid
If submitted, the following is included in the bid:
- CPM bid
- Creative redirect or Google-hosted creative ID
Google respects the data entrusted by Ad Manager publishers. As a buyer using RTB, you are bound by the RTB section of the buyer policies.
