1. What is Open Bidding?
Open Bidding, also known as exchange bidding, is a feature within Google Ad Manager that allows publishers to leverage a unified auction system to access demand from various ad networks, exchanges, and demand-side platforms (DSPs). It simplifies the monetization process by replacing the traditional waterfall model with a real-time bidding environment. Open Bidding enables publishers to achieve maximum revenue by increasing competition among multiple demand sources simultaneously.2. How Does Open Bidding Work?
Open Bidding operates on a server-to-server connection, where Google Ad Manager communicates directly with participating demand partners. Let's dive into the key steps involved in the Open Bidding process:- Ad Request: When a user visits a publisher's website or app, an ad request is generated and sent to Google Ad Manager.
- Dynamic Allocation: Ad Manager determines the available ad inventory and initiates the dynamic allocation process.
- Bid Requests: Ad Manager sends bid requests containing information about the ad unit, user demographics (if permitted), and targeting parameters to the participating demand partners.
- Bid Responses: Demand partners receive the bid requests, evaluate the available inventory, and submit their bid responses, including the bid price and other relevant information.
- Unified Auction: Ad Manager conducts a unified auction, comparing the bid responses from all demand partners and selecting the highest-paying bid.
- Ad Serving: Once the winning bid is determined, Ad Manager serves the corresponding ad creative from the winning demand partner.
