Direct buying in advertising goes back to the era of print media dominance. Before the rise of programmatic advertising, advertisers and publishers had to do things the old-fashioned way- sit down and manually negotiate the deals for ad space. This practice goes back to the 1800s. Cut to 2023, this ‘haggling in a bazaar’ practice has been moved to a digital marketplace – Ad exchange. 

Programmatic advertising is expected to reach a global figure of USD 725 billion by 2026. Ad exchanges are at the forefront of this revolution, providing a streamlined and efficient platform for buying and selling ad space. 

What is an ad exchange?

An ad exchange is an online marketplace or an ad tech technology utilized by platforms such as ad networks that enable advertisers and publishers to buy and sell digital advertising inventory in a real-time bidding (RTB) environment. Ad exchanges use programmatic advertising technology to allow ad inventory to be auctioned off to the highest bidder in real-time. Ad exchanges provide an efficient way for advertisers to reach their target audience and for publishers to monetize their website or app inventory. 

How does an ad exchange work?

• Publishers partner with an ad exchange and add their ad inventory platform.
• It matches the publisher’s ad inventory with available demand from advertisers who are interested in reaching the publisher’s audience.
• Advertisers bid on the publisher’s ad inventory in real-time, with the highest bid winning the auction.
• The ad exchange serves the ad to the publisher’s audience and tracks the ad impression and performance data.

The publisher earns revenue for the displayed ad based on the chosen pricing model. The ad exchange provides reporting and performance analytics to them to track their ad performance and optimize their inventory for maximum revenue.

What are the benefits of an ad exchange for publishers?

• Publishers can present their ad inventories to buyers across the world. This means that they get to capture demand from global advertisers and make more profits. 
• Ad exchanges ensure that publishers are not displaying competitor ads at the same time to maintain the value and integrity of each ad. 
• Publishers can set a minimum CPM for the bidding to ensure competitive prices for their inventory units. 
• By using an ad exchange, publishers can monitor their choices with respect to the size, design, and color of the ads that they want to display. This helps strike the right balance between ads and user experience on their website. 

Types of Ad Exchanges for publishers

1. Open Ad Exchange

With Open Ad Exchanges, publishers get to make their ad inventories available for any and every possible buyer including ad tech platforms such as ad networks and DSPs (Demand side platforms). This opens up the possibility of getting the best deals and multiple buyers are bidding on their ad inventories. 

2. Private Ad Exchange

Private ad exchange is a closed environment where the publishers get to decide who they want to open their inventories for. In the case of this type of Ad Exchange, the buyers available on the platform are mostly large-scale and premium. Publishers control the access of buyers to their inventory.  This controlled ad exchange platform ensures that publishers do not face any ad fraud or safety concerns.
