What Is a DSP? Demand Side Platform Advertising Explained

What Is a DSP? Demand Side Platform Advertising Explained

7 Min Read

As the advertising world continues to evolve, the technology does as well, and sometimes it’s hard to keep it all straight. Programmatic advertising and the tools that go along with it, like demand side platforms, have made it easier than ever for advertisers to access ad inventory across publishers and reach their target audience. But how exactly does a DSP work and what are you really buying?

Demand Side Platform Definition

What is a DSP and how does it work? A DSP is software that allows advertisers to buy ad impressions in an automated fashion.

Still not quite clear? Programmatic advertising has the same fundamentals as any kind of transaction – there is a buyer and a seller. DSP advertising is a tool used on the buying side, AKA the advertiser’s side, of the transaction when buying advertising impressions. This software allows advertisers to buy media placements across mediums, including display, video, mobile, and even Connected TV, as well as across different publishers.

Advertisers who use DSP advertising are able to set up their campaign, buying ad impressions from an ad exchange (a pool of impressions from various publishers) for a predetermined bid price. Additionally, they can use the DSP technology to target their audience, whether it’s by demographic (ex. Adults 18-34) or by interest (ex. Have purchased plant-based meat). DSPs use the bid price and audience targeting information to sift through inventory available from the ad exchange and select the best impressions available for your campaign.

What is Programmatic Advertising?

Maybe we’re getting ahead of ourselves here. Let’s back up and define—what exactly is programmatic advertising? Programmatic advertising is a way of buying ad placements that is automated. Instead of the manual process of campaigns being bought, set up, and maintained by humans, programmatic advertising uses ad exchanges and other algorithmic software that allows for machine-driven buying of inventory. 

Programmatic advertising allows you to take ad buying into your own hands, allowing you to set up your campaign immediately and to track results in almost real-time. And for publishers with ad inventory, it easily allows them to make these impressions available to advertisers without having to work with a multitude of companies directly.

There are multiple ways that an advertiser can buy advertising programmatically. They can buy guaranteed placement from specific publishers if they want to control exactly where their ads are showing up.

Another popular programmatic option is real-time bidding (RTB), which purchases ad impressions in an auction format. When the software recognizes an ad impression that fits the parameters the advertiser laid out in the demand side platform, such as target audience and content type, it will bid for that placement. If it outbids the other campaigns and wins the placement, the ad will show up seemingly instantaneously for the viewer. 

What Is the Difference Between DSP and SSP?

A DSP definition can be even better understood within the context of its counterpart – SSP. SSP stands for Supply Side Platform and is the other side of the transaction when it comes to programmatic ad buying. Where you, the advertiser, uses a DSP to plug into the ad exchange and purchase advertising, publishers utilize a SSP in much the same way to make their inventory available to you.

The SSP allows publishers to add their inventory to exchanges and set a floor price, meaning that they can guarantee their inventory is sold for a minimum price that aligns with their business goals. So while advertisers use a DSP to try to get ads at the best (read: lowest) price for their desired inventory, publishers use SSPs to help ensure that they can sell their inventory at the highest possible price. The DSP and SSP work together to find a middle ground that works for both parties. 

What Are Examples of Demand Side Platforms?

Now that we’ve answered the question “what is a DSP?” perhaps you want to check out a few concrete examples. Below is a list of some commonly used services:

  • The Trade Desk
  • MediaMath
  • Adform
  • Roku Oneview
  • Adobe Advertising Cloud DSP

How Do Demand Side Platforms Make Money?

There are a few different ways demand side platforms use to make money. Some DSPs take a percentage of the overall campaign cost so the more you spend, the more they make. Other DSPs charge a flat monthly rate for access to their service. The flat monthly fee model may be one fee regardless of the cost of the ad campaign, or it may come with a minimum investment required for the advertiser to put into the campaigns running on the DSP. While these fees may be nominal on their own, they can add up over time, especially if you are using multiple services or running multiple campaigns.

How Does Performance TV Stack Up?

Now that you are a programmatic expert, you may be wondering how Performance TV with MNTN compares to DSP marketing. While DSPs help you access CTV/OTT inventory, they are not without their faults, many of which Performance TV addresses. While we’ve done an in-depth breakdown of DSP vs. Performance TV, let’s review a few highlights:

  1. Pricing: As mentioned above, DSPs make money in a few different ways, including monthly fees or percentages of overall campaign costs. Unfortunately, there are often hidden fees when it comes to accessing various audiences, which can add up quickly. Performance TV is all about price transparency, as well as access to great tools. Included within the cost is access to a creative suite, as well as a customizable reporting dashboard and the ability to tap into tens of thousands of third-party audiences via its integration with Oracle Data Cloud—no hidden fees allowed.
  2. Reporting: Speaking of the Performance TV reporting dashboard, this is another efficiency that DSPs do not offer. While DSPs provide essential insight into campaign performance, it is often delivered piecemeal, meaning that you’ll be spending more time deciphering performance rather than optimizing it. With the Performance TV dashboard, all of your campaign data is available in one spot and can be customized for the view that makes the most sense for your business. Plus, your information can be added to your Google Analytics account, making it easy to track your CTV campaign along with your other performance channels.
  3. Ad Quality: There is a lot of content out there and it’s not all created equal. When buying through a DSP, there is a lack of transparency as to what content your ads are actually running on. The content may not be brand safe or your ad may run on skippable inventory meaning your creative is not viewed to completion. Performance TV offers Living Room Quality, which ensures that your ad is only running on non-skippable CTV inventory that runs through your smart TV or CTV enabled devices (not a phone, tablet or the like). Additionally, it’s served only on top-tier streaming services so you can be sure your ad is showing up only on quality content. 
  4. Set-Up: DSPs often require a third-party, such as an advertising agency or media buyer, which adds more back-and-forth communication, as well as additional cost. Performance TV keeps it simple: upload your creative, select your audience and flight dates and launch your campaign. In the words of one of our favorite TV personalities, how easy is that?
