An ad network is a platform that acts as an intermediary between advertisers who wish to place advertising and websites that have advertising space to sell. These networks collect available advertising space from different websites and offer it to advertisers for purchase, facilitating the process for both advertisers and publishers.
For advertisers, an ad network offers an easy way to purchase ad space on a variety of sites without having to negotiate directly with each site. These platforms can target their ads based on a variety of criteria, such as demographics, interests or behavior, to ensure that their message reaches the right audience. On the other hand, for websites or publishers, these networks represent a source of revenue, as they can monetize their content without having to actively seek out advertisers.
Given the diversity of the digital ecosystem, there are different types of ad networks, including specialized networks in display, video, mobile, among others.
