Ad Network

Definition: An ad network is a platform or system that connects advertisers with publishers, facilitating the buying and selling of advertising space. Ad networks play a crucial role in the digital advertising ecosystem by acting as intermediaries, enabling advertisers to reach a broader audience and publishers to monetize their digital properties.

Key Components and Functions:

  1. Advertisers:
    • Advertisers are individuals, companies, or organizations seeking to promote their products or services through online advertising. They join ad networks to access a wider range of publishers and audiences.
