What is Programmatic Advertising?

Programmatic advertising is a modern approach to buying and selling digital ad space using automated technology. Unlike traditional methods that rely on manual negotiations, programmatic advertising leverages data and algorithms to make the process more efficient and effective.


At its simplest, programmatic advertising refers to the automated buying and selling of online advertising space. This means using software to purchase digital ads instead of human negotiations. The automation makes transactions more efficient and faster, reducing the time and effort required to manage ad campaigns.


Automation is the heart of programmatic advertising. It allows advertisers to buy ad space in real-time, targeting specific audiences based on various data points. This real-time bidding (RTB) process happens in milliseconds, ensuring that ads are served to the right people at the right time.


Programmatic advertising relies heavily on data. By analyzing user behavior, demographics, and other signals, advertisers can create highly targeted campaigns. This data-driven approach ensures that ads are more relevant to the audience, improving engagement rates and return on investment (ROI).

Real-Time Bidding (RTB)

Real-time bidding (RTB) is a key component of programmatic advertising. In RTB, ad impressions are bought and sold through auctions that occur in real-time. When a user visits a website, an auction happens within milliseconds to determine which ad will be displayed. The highest bidder wins the auction, and their ad is shown to the user.

Demand-Side Platforms (DSPs)

A Demand-Side Platform (DSP) is software used by advertisers to buy ad space automatically. DSPs connect to multiple ad exchanges and supply-side platforms, allowing advertisers to bid on a wide range of inventory. DSPs use algorithms to determine the best ad placements based on the advertiser’s targeting criteria and budget.

Supply-Side Platforms (SSPs)

A Supply-Side Platform (SSP) is the counterpart to a DSP, but for publishers. SSPs help publishers manage and sell their ad inventory in real-time. By connecting to multiple ad exchanges and DSPs, SSPs ensure that publishers get the best possible price for their ad space.

Ad Exchanges

An ad exchange is a digital marketplace where DSPs and SSPs interact to buy and sell ad inventory. Ad exchanges facilitate the bidding process, making it easier for advertisers to find the right placements and for publishers to monetize their content. This marketplace model ensures transparency and competition, benefiting both parties.

In summary, programmatic advertising revolutionizes how digital ads are bought and sold, making the process faster, more efficient, and highly targeted. By leveraging automation and data, it ensures that ads reach the right audience at the right time, maximizing ROI for advertisers and revenue for publishers.

Next, we’ll delve into how programmatic advertising works in more detail, breaking down the steps from targeting to optimization.

How Programmatic Advertising Works

To understand programmatic advertising explained in detail, let’s break down the process into its core components: targeting, bidding, ad serving, optimization, real-time insights, and the role of AI and machine learning.


When a user visits a website, the publisher’s platform identifies the available ad space. The Demand-Side Platform (DSP) then uses data—like online behavior and interests—to determine which ads are a good match for the user. This precise targeting ensures that the right ads reach the right people.

Example: The Amanda Foundation used programmatic signals like location and browsing behavior to tailor specific animal images to users, increasing the chances of adoption.


The moment a user lands on a webpage, the DSP calculates bids for the ad spot in real-time. This process, known as Real-Time Bidding (RTB), happens in milliseconds. The highest bid wins the ad space, ensuring that the most relevant ad is shown to the user.

Fact: Real-time bidding is an open marketplace, making it highly competitive and dynamic.

Ad Serving

Once the highest bid is determined, the ad is instantly served to the user. This seamless process ensures that the ad appears almost instantaneously, creating a smooth user experience.

Case Study: Progressive Insurance uses advanced targeting to serve ads to homeowners watching home improvement shows, ensuring the ad is relevant to their current interests.


With each ad impression, advertisers gather performance data. This data is used to optimize future bids and improve targeting. The continuous cycle of data collection and analysis helps in refining the ad strategy for better results.

Statistic: Advertisers lost more than $68 billion globally to ad fraud in 2022, highlighting the importance of continuous optimization and monitoring.

Real-Time Insights

Real-time insights allow advertisers to track the performance of their ads instantly. This immediate feedback helps in making quick adjustments to improve the effectiveness of the campaign.

Quote: “Gone are the days of using limited data and guesswork. Now, thanks to real-time data, machines handle everything at a speed humans can’t match.”

AI and Machine Learning

AI and machine learning play a crucial role in programmatic advertising. These technologies analyze vast amounts of data to find patterns and predict outcomes. This enables more accurate ad placements and lower costs.

Trend: Dynamic Creative Optimization (DCO) uses AI to deliver highly personalized ads, ensuring that the right message reaches the right user.

Programmatic Advertising Process - programmatic advertising explained

Programmatic advertising leverages advanced technology to automate and optimize the ad buying process. From targeting the right audience to real-time bidding and ad serving, every step is designed to maximize efficiency and ROI.

Next, we’ll explore the different types of programmatic advertising and how they cater to various advertising needs.

Types of Programmatic Advertising

Programmatic advertising isn’t one-size-fits-all. Different types cater to different needs. Let’s break down the main types:

Display Ads

Display ads are the classic banner ads you see across the web. They appear on various websites and can be tailored to reach specific audiences. Think of them as the backbone of online advertising. For example, a health and fitness brand targeting millennials can use display ads to appear on health blogs and lifestyle websites frequented by their audience.

Video Ads

Video ads are great for storytelling. They grab attention and engage viewers deeply. With programmatic advertising, you can target these ads more efficiently. For instance, a brand like Geico uses programmatic video ads across TV commercials, social media, and websites to create a cohesive, cross-platform awareness campaign. These ads are especially effective on platforms like YouTube and streaming services.

Native Ads

Native ads blend seamlessly with the content around them. They look and feel like organic content, making them less intrusive. You’ll often find these ads as sponsored articles or posts that match the style and tone of the platform. This type of ad is perfect for subtle promotion. For example, when browsing a news site, you might see an article that fits right in but is actually a native ad.

Connected TV (CTV)

Connected TV (CTV) ads target viewers who stream content on platforms like Roku or Hulu. These ads are shown on TVs but are delivered programmatically. This is a growing area as more people shift from traditional TV to streaming. Brands like Progressive have effectively used CTV ads to target specific demographics, such as young homeowners watching home improvement shows on Hulu.

Digital Out-of-Home (DOOH)

Digital Out-of-Home (DOOH) takes traditional billboard advertising into the digital age. These are dynamic ads displayed on screens in public places like bus stops or elevators. They can change in real time based on data. For instance, during morning school drop-offs, DOOH ads near schools might target parents with relevant messages. This type of advertising is all about reaching people on the go.

By using a mix of these types, advertisers can create a comprehensive and effective campaign that reaches their audience across multiple touchpoints. For example, a campaign might start with display ads to build awareness, use video ads for deeper engagement, and culminate in CTV ads for a lasting impact. This cross-platform storytelling is what makes programmatic advertising so powerful.

Next, we’ll dive into the benefits of programmatic advertising and how it can transform your marketing efforts.

Benefits of Programmatic Advertising

Programmatic advertising offers several benefits that make it a game-changer in digital marketing. Let’s break down the key advantages:


Programmatic advertising automates the buying and selling of ads, which saves time and reduces the need for manual intervention. This automation streamlines the process, allowing advertisers to focus on strategy rather than logistics. For publishers, automation tools make it simpler to sell ad space, reducing the time required to find advertisers.

Precision Targeting

One of the standout features of programmatic advertising is its precision targeting. Advertisers can target specific audiences based on a wide range of criteria, such as demographics, interests, and online behavior. This ensures that ads are shown to the most relevant audience, maximizing the effectiveness of the ad spend. For example, a health and fitness brand can target millennials interested in wellness, ensuring their ads appear on health blogs and relevant social media platforms.


Programmatic advertising allows advertisers to reach a large audience by purchasing ad space from any available inventory. This scalability is particularly beneficial for brands looking to expand their reach quickly. As noted in the Publift article, Hestan Culinary experienced a 300% increase in return on ad spend after adopting programmatic advertising.

Improved ROI

By using data-driven strategies and real-time bidding, programmatic advertising ensures that ad budgets are used efficiently. Advertisers get a better return on investment (ROI) because their ads are more likely to reach the right people at the right time. The Healthcare Staffing Agency case study highlights this, where monthly applications increased while advertising spend decreased.

Real-Time Data

One of the biggest advantages of programmatic advertising is access to real-time data. Advertisers can monitor the performance of their campaigns in real-time and make adjustments as needed. This agility allows for continuous optimization, improving the overall effectiveness of the campaign. For instance, The Economist managed to double its subscription target within five weeks by leveraging real-time data to tweak its strategy.

Cross-Device Campaigns

Programmatic advertising isn’t limited to just one type of device. It allows for cross-device campaigns, meaning ads can reach users on their desktops, smartphones, tablets, and even connected TVs (CTV). This ensures a cohesive and consistent message across all platforms, enhancing the user experience and increasing the likelihood of engagement.

These benefits collectively make programmatic advertising a powerful tool for modern marketers. By leveraging efficiency, precision targeting, scalability, improved ROI, real-time data, and cross-device capabilities, brands can significantly enhance their marketing efforts.

Next, we’ll explore the key components of programmatic advertising and how they work together to deliver these benefits.

Key Components of Programmatic Advertising

To truly understand programmatic advertising explained, we need to dive into its key components. These elements work together to automate and optimize the ad buying process. Let’s break them down:

Demand-Side Platforms (DSPs)

A Demand-Side Platform (DSP) is where advertisers buy ad impressions. Think of it as a one-stop-shop for purchasing ad space across numerous publishers. DSPs help advertisers decide which impressions to buy and at what price. They use data to target specific audiences based on demographics, behavior, and more.

Example: Google Ads acts as a DSP but is limited to Google’s inventory. Third-party DSPs, like Amazon DSP, offer access to a wider range of inventory beyond just Google.

Supply-Side Platforms (SSPs)

On the flip side, Supply-Side Platforms (SSPs) are used by publishers to sell their ad space. SSPs connect publishers to multiple ad exchanges, DSPs, and networks at once, maximizing the chances of selling their inventory at the best possible price.

Example: An SSP allows a news website to sell ad space to the highest bidder among multiple advertisers.

Ad Exchanges

Ad exchanges are the marketplaces where DSPs and SSPs meet. Here, advertisers bid on ad impressions in real-time. The highest bidder gets their ad displayed. This process happens in milliseconds, ensuring that ads are shown to the right audience at the right time.

Example: Google Ad Exchange connects buyers using Google Ads with publishers using AdSense.

Data Management Platforms (DMPs)

Data Management Platforms (DMPs) collect, manage, and analyze large sets of data. They help advertisers understand their audience better by creating detailed user profiles. This data is crucial for targeting the right audience and optimizing ad campaigns.

Example: A DMP can track user behavior across different websites and devices, helping an advertiser target users who are most likely to convert.

Ad Networks

Ad networks aggregate ad space from various publishers and sell it to advertisers. They were the precursors to DSPs and SSPs but still play a role in programmatic advertising by providing additional inventory.

Example: An ad network might bundle ad space from several niche websites and sell it to an advertiser looking to target a specific audience segment.

Ad Servers

Ad servers are the technology platforms that deliver ads to websites. They store ads, manage ad delivery, and track performance metrics. Ad servers ensure that the right ads are shown to the right users and provide detailed reports on ad performance.

Example: An ad server can track how many times an ad was shown, clicked, and converted, providing valuable insights for optimizing future campaigns.

These components—DSPs, SSPs, ad exchanges, DMPs, ad networks, and ad servers—work in harmony to make programmatic advertising efficient and data-driven. They automate the buying and selling of ad space, ensuring that ads reach the right audience at the right time.

Next, we’ll look at best practices for programmatic advertising, including goal setting, audience segmentation, and fraud prevention.

Child Rescue Alert

Child Rescue Alert, a charity focused on finding missing children, turned to programmatic advertising due to limited financial resources. By targeting users based on geographic areas where children had gone missing, the charity could issue more effective appeals. This shift allowed them to move from one targeted appeal ad per week to a more dynamic and responsive advertising strategy, ultimately helping to save lives.


InterContinental Hotels Group (IHG) implemented programmatic advertising to enhance their marketing efforts. By using data to understand customer preferences and booking behaviors, IHG could serve personalized ads promoting relevant hotel deals and destinations.
