An ad exchange is a marketplace for online advertising transactions between publishers and advertisers. They provide a platform for real-time bidding (RTB) on ad space.
These exchanges help publishers maximize the revenue they earn from their premium inventory through cost-per-mille (CPM) pricing models by making it available to the highest bidder. Advertisers benefit by getting access to a larger pool of potential inventory and being able to bid on it in real-time.
They are essentially the modern-day ad network. This guide will detail the major types of ad exchanges available today, as well as how they work and differ.
Ad Network vs. Ad Exchange
An ad network is a company that connects advertisers to websites that want to host advertisements. The ad network will typically take a cut of the ad revenue.
They sort inventory into specific categories and charge a CPM rate for each.
An ad exchange is a digital marketplace where inventory from multiple publishers is made available to advertisers in real-time. Advertisers can bid on this inventory through a process called programmatic buying or RTB.
Auctions always occur on an ad exchange to ensure that each advertiser has a fair chance to bid on the ad inventory. Publishers also use auctions when there is unsold inventory that an ad network cannot fill.
Publishers and advertisers can buy and sell inventory directly in an ad exchange, and it is based on market competition, not media inventory.
Ad networks used to be the primary way for advertisers to buy ad space. Ad exchanges have largely replaced ad networks because they are more efficient, transparent, and provide a better user experience.
Open vs. Private Exchanges
An open exchange is a digital marketplace available to sellers and buyers where inventory from multiple publishers is made available to advertisers in real-time. Advertisers can bid on this inventory in real-time.
Examples of open exchanges are Google Ad Exchange, Openx, Xandr, and Rubicon Project.
A private exchange is an invitation-only private marketplace (PMP) where inventory from a specific group of publishers is made available to a particular group of advertisers.
This makes the process more secure than open ad exchanges.
Ad Exchange vs. DSP & SSP
Since we understand what an ad exchange is and how it works, let us look at DSP and SSP. A demand-side platform (DSP) is a system that allows for the buying of ad impressions across multiple ad exchanges in real-time.
A supply-side platform (SSP) is a system that allows publishers to manage the sale of their ad impressions in real-time.
DSPs & SSPs work to identify which bidders qualify for a specific website. They provide data to ad exchanges that enable the buying and selling process through real-time auctions.
The difference between DSPs and SSPs is that advertisers use DSPs to buy inventory while publishers use SSPs to sell inventory. Both play a significant role in the programmatic ecosystem.
Google Ad Exchange
Google Ad Exchange was previously known as the DoubleClick Ad Exchange. It works by connecting advertisers with publishers who want to host advertisements. Advertisers can bid on ad space in real-time through Google’s interface.
Google Ad Exchange offers RTB, private auctions, and preferred deals to advertisers and publishers looking to buy and sell advertising space. To be eligible, one has to have a Google Ad Manager account and have access to AdX, either directly or via a Google partner.
Another eligibility criterion is that the site or app should have high-quality content and follow Google’s ad policies.
Google Adsense is an ad network that connects advertisers to websites that want to host advertisements. The ad network will typically take a cut of the ad revenue. They sort inventory into specific categories and charge a CPM rate for each.
Google Adsense is great for new sites with lower traffic, whereas Google AdX is excellent for more established sites with stronger traffic.
