Programmatic Business Model: Ad Network vs. Ad Exchange
A network and ad exchange are two crucial components of the programmatic marketplace. In large part, they share a similar objective, gathering publishers’ inventory to sell it programmatically to advertisers. Those two terms are frequently used interchangeably, which confuse their distinct roles in media buying.
Despite the apparent similarities, ad networks and ad exchanges have distinct functions in the programmatic ecosystem and operate differently. Further, I am going to outline the key differences between the two terms to clear the confusion.
What is an ad network?
The term ad network emerged simultaneously with digital advertising. In the early 90s, digital advertising faced a critical scaling problem. Advertisers and publishers found it increasingly difficult to negotiate deals manually. Ad networks lead the push toward automation, streamlined the deals, managed ad inventory, and transacted the media buys.
Traditional ad networks relied on the waterfall to sell its inventory, and programmatic adoption pushed ad networks to the digital marketplace’s margins. The arrival of openRTB made media buys more efficient through ad exchanges.
What is an ad exchange?
An ad exchange is a virtual marketplace where supply and demand meet to trade inventory via open auction without intermediaries’ involvement. Ad exchange uses a real-time-bidding technology to run auctions. It gathers ad networks, DSPs, publishers, and advertisers to sell inventory to the highest bidder on the impression-by-impression basis.
The introduction of ad exchanges, many of which adopted the name SSP later in the game, created a truly international media trading.
Traditional ad networks had a limited scope, unable to provide scale to global advertisers, who need diverse audiences across different geos and content niches. Ad networks had issues with integrations and trading inventory with the external sources.
What is a programmatic ad network?
Ad networks evolved, and many adopted programmatic technologies, most commonly header bidding. At the core, the business model remains the same – ad network acts as an intermediary between advertisers and publishers. Ad networks sort inventory into categories according to the specific audience segments and offer them to advertisers.
If before, ad networks concentrated on selling the remnant traffic, modern programmatic ad networks focused on premium inventory and offering it to advertisers for higher prices. Alternatively, ad networks are used to sell owned media by the large publishers or media houses, to get a better price for their premium inventory and flexibly manage their demand.
Programmatic ad networks started using more sophisticated programmatic trading methods, such as reserved deals or private marketplaces, to provide inventory to hand-picked advertisers on exclusive conditions before entering the open auction.
The addressability across the web and in-app will be fading out in light of the looming phase-out of third-party cookies for web and IDFA for iOS devices. This can sparkle the new dawn of programmatic ad networks, mainly vertical ad networks, more on that read in our guide.
Programmatic vs display advertising
Display advertising is one of the oldest and most iconic types of digital promotion. It usually consists of banners of different sizes and formats, served through display ad networks. The dominant network of that kind is Google Display Network (GDN), which covers close to 2 million websites and reaches 90% of the internet users.
GDN is a closed network that provides limited insights into its algorithms and does not reveal information about the bids. You take what you can get. In contrast, programmatic is an open and transparent system, that involves multiple ad exchanges, ad networks and agencies, where one can flexibly choose inventory and price for it. Programmatic ecosystem includes not just display ads on the web, but also in-app, CTV, DOOH in a variety of formats from video ads to rich media interactions.
Key differences: Ad Network vs. Ad Exchange
Ad exchanges, commonly regarded as SSP, are a lot like stock exchanges, marketplaces, where a lot of sellers and buyers meet to trade their inventory on real time auctions. Ad networks are a lot like retailers, who have tight connections from local suppliers and a customer base of advertisers hungry for their audience segments.
