What is the official name of Facebook's ad auction system?

The official name of Facebook's ad auction system is the "ad selection algorithm." This system is designed to determine which ads to show to users based on a variety of factors, including bid amount, estimated action rates, and ad quality. The algorithm evaluates ads within the context of available inventory and user engagement to ensure that the most relevant and effective ads are shown.

The ad selection algorithm operates on a sophisticated framework that optimizes for both user experience and advertiser goals. It analyzes user behavior and preferences, which helps deliver the right message to the right audience. The methodology behind the algorithm is essential for both advertisers looking to achieve their campaign objectives and users who benefit from seeing ads that are pertinent to their interests.

The other choices, while related to advertising on the platform, do not represent the official name of the ad auction system. The ad bidding system is more about how advertisers set their bids. Facebook Ads Manager is a tool used by advertisers to create and manage ad campaigns. Dynamic ad placement refers to the automated optimization of ad placements across different formats and devices, rather than the broader process of selecting ads in the auction context.
