Though Ad Networks and Ad Exchanges serve the same purpose for publishers, the backstory is quite contrary.
We know it’s an oversimplified version of what you need to do to run Google Ads, but the goal is to convey the ‘straightforwardness’ of the process.
Do you know why it’s pretty easy to sign up for Google AdSense?
Because it’s an ad network. Not just Google AdSense, almost all the ad networks offer you more or less same sign-up and monetization setup. When it comes to ad exchanges, the story is completely different. In fact, you need to pass through a few complexities and technical configurations to complete the Ad Exchange setup. However, you can skip it all by partnering with an SSP. And, the effort is worth it.
As you’ve been dealing with doubts already, we don’t want to make the situation worse. Let’s start with the basics.
What is an Ad Network?
Ad Network is a piece of technology which bundles remnant inventories from the pool of publishers and sells it to the advertisers. Most probably, you already know what there is to know about ad networks from a publisher’s perspective.
Here’s a quick refresher to help you.
How do ad networks work?
Ad Networks collects the pool of inventories from publishers across the globe and bundles it based on the verticals, demographics, and context.
On the other hand, advertisers are allowed to choose the verticals, demographics, etc. to run display ads. Once the target criteria have been set, the ad network will match the inventories with the advertisers’ request.
The advertiser who’s willing to pay the price determined by the ad network’s algorithm gets the inventory and ad creative from the advertiser is served.
Publishers will be paid for the number of impressions served (most probable revenue model).
You can correlate ad networks with your sales team or even yourself. Imagine how you’re trying to sell the ad inventories available on your website to the advertisers by directly connecting with them. You connect, negotiate, and serve the ads. Ad Networks does the same, but it connects millions of publishers with tens of thousands of buyers using its own platform. You’re on one side of the platform placing the inventory for sale while the advertiser is on the other side of the platform buying your inventory (along with many others’).
What is an Ad Exchange?
Ad Exchange is a technology platform where publishers and advertisers transact impressions in real-time based on behavioral data of the readers. Unlike ad networks, ad exchanges allow publishers to determine the floor price and help them sell impressions (not bundled inventories) in real time to the advertisers.
How do ad exchanges work?
Both publishers and advertisers use respective technologies (SSP and DSP) to connect to ad exchanges and transact impressions effectively.
You can analogize ad exchanges with stock exchanges. Similar to how stock exchange permits the buyers and sellers to transact stocks (or bonds, etc.), ad exchanges allow you to transact ad impressions in real-time.
Ad Networks Vs Ad Exchanges
One thing is certain. Both ad networks and ad exchanges help publishers to sell remnant inventories, thus, ensuring higher ad revenue and fill rates.
So, are there any differences between ad networks and ad exchanges? If so, what are the differences and how to know which one is right for you?
Well, there are some differences you ought to know to make informed decisions.
Ad Networks – They collect inventories, package them based on vertical, context, etc. and sell it to the advertisers in bulk. Price is determined by the ad network’s algorithm.
Ad Exchanges – Ad Exchanges transact ad impressions (not inventories) in real-time based on the user data and some other factors. The price of the impressions (CPM) is led by the competition in the market.
Ad Networks – The ad networks offer several ways to target readers including RON (Run on all sites on the network), ROS (Run on specific sites on the network), IAB categories (Vertical), Context (keywords), Geo and time of the day, and browser type. As you could see, advertisers aren’t capable of targeting the users here. They’re only targeting the relevant sites, time, browsers, etc. in the hope of finding the right users. This also means your readers won’t bother clicking the ads.
Ad Exchanges – On the contrary, ad exchanges allow advertisers to bid for impressions based on the user data and context. The platform facilitates cookie syncing process, thus, ensuring the right users are targeted with the right ads.
Ad Networks – Ad Networks don’t require any sort of middlemen to monetize. It takes almost 40 percent of whatever you’ve earned through the platform. For instance, Google AdSense, the world’s largest ad network takes 32% of your revenue for the service provided.
Ad Exchanges – Ad Exchanges requires a middleman (SSP) to connect. However, SSPs usually charge anywhere between 10% to 20% in most cases.

d. CPM and Fill Rates
Ad Networks – Ad networks wouldn’t be able to fill your inventory completely. Although they claim 100% fill rates, it is occasional and comes with other disadvantages. Especially, your CPMs are lower when you use ad networks for filling your inventories completely.
Ad Exchanges – Ad Exchanges can guarantee you higher fill rate and the best possible CPMs for your ad impressions. Besides, programmatic solutions like Header Bidding can get you 100% fill rate without compromising the CPM.
e. Setup and Configuration
Ad Networks – Ad networks are quite easy to get started. As a publisher, you don’t need to worry about the complex setup.
Ad Exchanges – Ad Exchanges require you to set up ad server, line items, etc. However, your SSP will take care of the setup and optimization process.
Ad Networks – The ad networks were developed to help publishers sell the increasing inventories to the right advertisers. Advertisers got the inventories across the globe, which in turn, allowed them to reach the audience worldwide.
Ad Exchanges – Ad exchanges were invented to help mid-sized and premium publishers to transact impressions rather than bundled inventories. It helps advertisers to target users, not just context. You can consider ad exchanges as the higher version of ad networks.
