What is a Demand Side Platform?

If you’ve only known digital advertising as it is today, you might find it hard to imagine that not too long ago—maybe 15 to 20 years—buying ad space meant endless phone calls, contracts, and manual placements. It was a time-consuming process. Fast forward to now, and programmatic advertising has changed the game, automating the whole process. At the heart of this transformation are Demand Side Platforms (DSPs), which streamline the process even further, helping advertisers efficiently reach their target audiences. Let’s dive into what DSPs do and why they’re important.

What is Programmatic Advertising?

Before we get into what DSPs are, let’s make sure we understand the world they sit within. Programmatic advertising refers to the automated buying and selling of digital ad inventory using technology platforms. It typically involves real-time bidding (RTB) auctions, as well as techniques like header bidding,  where advertisers compete for ad placements based on their target audience, budget, and other criteria. This process gets rid of the need for manual negotiations and insertion orders, making ad buying much more efficient, scalable and targeted.

What Exactly is a Demand Side Platform Anyway?

A demand-side platform (DSP) is a software platform that lets advertisers buy ad inventory from multiple publishers across the web through a single interface. It operates on the buy side of the programmatic advertising landscape, allowing advertisers to automate the process of bidding on and purchasing ad placements in real-time auctions.

Why Are Demand Side Platforms So Important?

DSPs have become indispensable for advertisers due to their ability to streamline the ad-buying process. They provide a centralized platform for managing campaigns, targeting specific audiences, optimizing bids, and analyzing performance data. Through automation, DSPs free up advertisers' time and resources, letting them focus on strategic planning and creative delivery.

How Does a DSP Work?

A DSP connects advertisers to ad exchanges and supply-side platforms (SSPs), which represent a publisher's inventory. When a user visits a website or app, the publisher’s site sends a bid request to the ad exchange. The DSP receives this request and evaluates it based on the advertiser's campaign criteria. If there's a match, the DSP places a bid in the real-time auction. If the bid wins, the advertiser's ad is then displayed to the user.

Demand Side Platform Vs Supply Side Platform: What’s the Difference?

While DSPs operate on the buy side, enabling advertisers to purchase ad inventory, supply-side platforms (SSPs) operate on the sell side. SSPs help publishers manage their ad inventory and maximize revenue by connecting them to multiple ad exchanges and DSPs. They allow publishers to set floor prices, control ad placements, and optimize their revenue. For a more detailed look at SSPs check out our blog “What is a Supply Side Platform?”

What are the Main Components of a DSP?

A DSP typically comprises several key components:

• Ad Exchange Integration: This connects the DSP to ad exchanges where inventory is auctioned.
• Campaign Management Tools: These enable advertisers to create, manage, and optimize their campaigns.
• Targeting Capabilities: This allows advertisers to target specific audiences based on things like demographics, interests, behavior, and other criteria.
• Bidding Algorithms: These automate the bidding process and optimize bids for maximum return on investment.
• Reporting and Analytics: This provides insights into campaign performance and audience behavior.

What are the Different Types of DSPs?

DSPs tend to be categorized into different types based on their features and focus:

• Self-Serve DSPs: These offer a user-friendly interface for advertisers to manage campaigns for themselves.
• Managed Service DSPs: These provide dedicated account management and support for advertisers.
• Full-Stack DSPs: These offer a comprehensive set of tools and services, including things like campaign management, creative development, and data analytics.
• Mobile DSPs: These specialize in mobile advertising, offering advanced targeting capabilities specifically for mobile devices.
• Video DSPs: These focus on video advertising and offer tools for managing video campaigns across different platforms.

How Do DSPs Help Advertisers Buy Ad Space More Efficiently?

DSPs offer lots of benefits that make ad buying more efficient:

• Bidding and buying automation, saving time and resources.
• Real-time bidding, increasing the chance of winning impressions.
• Targeting that allows advertisers to reach specific audiences, making sure their ads are seen by the right people.
• Tools for optimizing campaigns based on performance data, improving return on investment.
• Transparency that offers insights into ad placements and audience behavior, increasing accountability.

What This All Means for Publishers

The right DSPs can be a game-changer for your revenue. By connecting with multiple DSPs, you tap into a broader network of advertisers, which can boost fill rates and ensure your ad inventory is earning top dollar. Advanced targeting options from these DSPs mean your ads reach the right audience, increasing engagement and overall performance.

When you add header bidding into the mix, you’re maximizing every opportunity. Header bidding allows multiple DSPs to bid on your inventory simultaneously, ensuring that you get the highest possible price for each impression. This competitive bidding not only increases revenue but also provides better transparency into how your inventory is valued.
