Ad Network

Ad networks bundle publisher inventory into packages that are easier for advertisers to purchase. Instead of negotiating with hundreds of individual publishers, an advertiser can buy through a network that offers access to categorized inventory segments like sports enthusiasts or business professionals across its network of partner sites.

For growth teams, ad networks offer convenience and reach but less transparency and control than direct programmatic buying through DSPs. The value proposition depends on the network's unique inventory access and targeting capabilities. Some networks specialize in specific formats like native or video, specific audiences, or specific regions where they have strong publisher relationships. AI optimization within ad networks varies in sophistication, and growth teams should evaluate network performance based on actual conversion outcomes rather than proxy metrics like clicks. Growth engineers should test ad networks as part of a diversified acquisition strategy, monitoring for incrementality and ensuring that network-attributed conversions are not simply claiming credit for users who would have converted through other channels.
