The current programmatic media buying landscape is really just an extension of the traditional two-party system between advertisers and publishers. If you keep in mind what is being sold, who is selling it and who is buying, it should become a little clearer.
So What is the Difference Between DSPs and Ad Networks?
The acronym DSP stands for demand-side platform. It is a buyer’s side platform for advertisers, it allows advertising buyers to manage multiple ad exchange and data exchange accounts using one interface. An ad network works for the publisher side of the two-party system, connecting advertisers to publishers that have web pages with advertising -matching ad space supply from publishers with advertiser demand.
Let’s Define This Further
Demand-Side Platforms (DSP): These are used by media buyers at agencies and brands to manage and purchase digital advertising inventory from multiple ad networks through one interface. DSPs allow advertisers to buy ad impressions across a range of publisher sites, but targeted to specific users based on data such as gender, age, location and browsing behavior.
Using a single interface allows marketers to target a very narrowly defined audience segment at scale, without having to manage multiple ad networks or exchanges. The DSPs use the behavioral targeting data which is collected from cookies and data exchanges, to identify the audience segments. DSPs let the marketers choose audience characteristics and then publishes the ads depending on the target audience. The main advantage here is that marketers do not have to worry about picking the right websites to advertise on, as the DSPs can do the work for them.
- Access to multiple inventory sources — they connect to several ad exchanges and SSPs and offer several channels
- Media buyer can choose which sites to buy on
- You can set the price at you think each individual impression is worth
- Added Data segments — use third-party or first-party audience data to enhance buy
- There are many different DSPs in the marketplace and you need to set up a contract with each one to have access to their platforms
- Steep learning curve — it takes time to master the nuances of buying on each platform, unless you work with a partner like Digilant
Ad Networks: An advertising network aggregates, categorizes and sells a range of publisher inventory in a way that can be easily understood and purchased by advertisers on a fixed CPM basis, connecting advertisers to web sites that want to host advertisements. . By aggregating inventory, Ad Networks offer advertisers the ability to better reach their target audience while allowing publishers to sell their inventory more effectively. There are many types of Ad Networks and they focus on delivering different objectives. Some focus on delivering reach and price while others focus on audience demographics and quality.
There are three main types of ad networks:
- Platform for buying audience segments and data
- Platform for buying media
- Platform for creative optimization
Ad networks are often used by media companies to sell out their online display inventory. However, unlike DSPs, not all ad networks support real-time bidding. They will have to incorporate a DSP, in order to facilitate real-time bidding.
- Centralized source for inventory for media buyers and advertisers
- No need to buy from individual publisher sites
- Lack of transparency — site reporting often masked
- Fixed CPM — all impressions cost the same regardless of value
- No automation — you need to contract each buy with a separate IO
What’s the Takeaway?
Technology creates efficiencies between advertisers and publishers. A DSP enables media buyers to incorporate automation using machine learning into the media buying process, giving advertisers access to more sophisticated targeting tools, data and analytics to improve their advertising performance. DSPs consolidate purchasing needs in one platform. But in today’s world of data privacy regulations and walled garden most advertisers can’t afford to use only one DSP. Each DSP like Google, Facebook, Amazon, MediaMath and others all offer their own unique audiences, data and targeting capabilities. Not only that but if there are buys or a platform goes down you don’t have options. You can’t be overly reliant on the infrastructure of one partner because if they decide to change something that has implications for your business you can’t afford the lag time that might cause.
That’s why Digilant partners with all of the best platforms, giving media buyers a holistic view of their ad buys across multiple DSPs so that advertisers can measure results and get value from their ad spend.
