An ad network serves as an intermediary between advertisers and websites that want to host advertisements. In the context of display advertising, it provides a platform that enables advertisers to reach a broad audience by placing ads on multiple websites that are part of the network. This means advertisers can access various online spaces where their target audience is likely to be without needing to negotiate individually with each site.

Ad networks aggregate available ad space from a variety of publishers, making it easier for advertisers to manage their campaigns, target specific demographics, and optimize their advertising strategies. By using an ad network, advertisers can increase their visibility and reach potential customers more effectively across a range of sites.

In contrast, options that refer to creating ad content, online payment systems, or strategies for maximizing ad reach do not accurately describe the fundamental role of an ad network in display advertising. These processes are related to aspects of advertising but do not define the specific function that an ad network fulfills in connecting advertisers with publisher sites.
