Breaking down how programmatic advertising works
Today, programmatic advertising enables advertisers to purchase ad inventory across thousands of websites simultaneously using automated systems. This shift has transformed media buying from a relationship-based process to a data-driven, algorithmic approach that delivers greater efficiency and targeting precision.
While traditional banner ads and direct publisher relationships still have their place, programmatic marketing offers unparalleled scale and efficiency. The technology allows your digital marketing strategy to adapt in real time, responding to performance data and audience behaviours to optimise ad spend across multiple channels.
The programmatic advertising process relies on an interconnected ecosystem of platforms and technologies working in concert to deliver the right ad to the right person at the right time. These are:
Demand-side platforms (DSPs)
Demand-side platforms are sophisticated tools that allow advertisers to purchase ad inventory across multiple ad exchanges through a single interface. These platforms enable you to:
- Set targeting parameters based on demographics, interests, and behaviours Establish budget limits and bidding strategies Access inventory across thousands of websites, apps, and platforms Monitor campaign performance in real-time
- Popular DSPs include Google Display & Video 360, The Trade Desk, and MediaMath. These platforms serve as your command centre for programmatic campaigns, making managing complex media buying strategies easier.
Supply-side platforms (SSPs)
On the publisher side, supply-side platforms help website owners and app developers sell their ad inventory efficiently. SSPs connect to multiple ad exchanges and DSPs, creating competition for available ad space and maximising revenue for publishers. Major SSPs include Google Ad Manager, Xandr, and PubMatic.
Ad exchanges
Ad exchanges function as digital marketplaces where programmatic advertising transactions occur. These platforms facilitate real-time bidding (RTB) auctions, connecting buyers (through DSPs) with sellers (through SSPs). The Google Ad Exchange (now part of Google Ad Manager) is one of the largest, but multiple ad exchanges operate globally, each with unique inventory and publisher relationships.
Ad networks
While sometimes confused with ad exchanges, ad networks serve a different purpose in the programmatic ecosystem. Ad networks aggregate inventory from multiple publishers and sell it to advertisers, often focusing on specific niches or formats.
These networks typically offer less transparency than exchanges but can provide access to curated inventory pools. Many traditional ad networks have evolved to incorporate programmatic capabilities, blurring the lines between networks and exchanges.
Data management platforms (DMPs)
Data management platforms collect, organise, and activate audience data from various sources. DMPs help you build detailed audience segments based on browsing behaviour, purchase history, and demographic information.
This audience data powers the precise targeting that makes programmatic advertising so effective. Leading DMPs include Salesforce DMP, Oracle BlueKai, and Adobe Audience Manager.
Navigating programmatic advertising platforms
The market for programmatic advertising platforms has expanded significantly, giving advertisers many options to consider when implementing their programmatic strategy. Each platform offers different capabilities, inventory access, and pricing models.
Major programmatic advertising platforms
Several key players dominate the programmatic landscape:
- Google Marketing Platform combines analytics and advertising capabilities, including Display & Video 360 for programmatic buying. Its integration with Google’s vast ecosystem makes it a powerful choice for many advertisers.
- The Trade Desk is a leading independent DSP known for its sophisticated targeting capabilities and access to premium inventory across display, video, audio, and connected TV.
- MediaMath offers an enterprise-grade programmatic solution with advanced audience targeting and strong fraud prevention measures.
- Amazon DSP provides unique access to Amazon’s first-party consumer data and inventory across Amazon properties and third-party sites.
- Xandr (formerly AppNexus) delivers strong performance for advertisers and publishers with transparent auction dynamics and robust analytics.
Platform selection criteria
When evaluating programmatic advertising platforms, consider these factors:
- Inventory access: Assess which platforms provide access to the websites, apps, and channels your target audience frequents.
- Targeting capabilities: Compare the data sources, audience segmentation tools, and each platform’s targeting options.
- Transparency: Look for platforms that provide clear insights into where your ads appear, auction dynamics, and fee structures.
- Ease of use: Consider the interface, workflow, and technical requirements for managing campaigns effectively.
- Support and service: Evaluate the level of customer support, training resources, and strategic guidance available.
- Integration capabilities: Check how well the platform connects with your existing marketing tools and technology stack.
For many businesses, the best approach involves working with multiple complementary platforms rather than relying on a single solution. This multi-platform strategy provides broader reach and helps you leverage the unique strengths of different programmatic advertising platforms.
The programmatic advertising process in 6 steps
How does programmatic advertising work in practice? Let’s break down the process step by step:
- A user visits a web page – When someone navigates to a website with ad space available, the page begins to load, triggering the programmatic process.
- The publisher’s ad server sends bid requests – The website’s supply-side platform broadcasts information about the available ad impression, the user, and the context to multiple ad exchanges.
- DSPs evaluate the opportunity – Using the advertiser’s targeting criteria and bidding parameters, demand-side platforms decide whether to bid on the impression and how much to offer.
- Real-time bidding occurs – In milliseconds, an auction occurs among interested advertisers. The highest bidder wins the opportunity to display their ad, though factors beyond price (like ad relevance) may also influence the outcome.
- The winning ad is served—The selected ad appears on the web page before the page finishes loading, making it seamless for the user.
- Performance tracking begins – The advertiser tracks impressions, clicks, and conversions, generating data for future bidding strategies and campaign optimisations.
The programmatic advertising happens in less than 100 milliseconds—faster than the blink of an eye. The technology’s speed and efficiency allow for unprecedented scale in digital advertising operations.
When you buy ad space programmatically, you’re not just purchasing a spot on a specific website; you’re buying access to your target audience wherever they appear online.
This audience-first approach represents a fundamental shift from traditional media buying, focusing primarily on securing placement on specific websites or publications.
Types of programmatic advertising
Programmatic advertising encompasses several distinct models, each suited to different marketing objectives and campaign requirements:
Real-time bidding (RTB)
Real-time bidding (rtb) is the most common form of programmatic advertising, in which ad impressions are auctioned instantly. RTB offers flexibility and efficiency but provides fewer guarantees about where your ads will appear. This approach works well for performance-focused campaigns with clearly defined target audience segments.
Open RTB auctions give you access to the broadest range of inventory but typically come with less control over brand safety and context. However, advances in targeting and brand safety tools have made open exchanges increasingly viable for brand campaigns.
Programmatic direct
Programmatic direct (also called programmatic guaranteed) combines automation with the certainty of traditional direct buys. Advertisers negotiate directly with publishers for guaranteed ad placements but use programmatic technology to streamline delivery and optimisation. This approach is ideal for securing premium inventory on high-value sites where brand safety and context are paramount.
With programmatic direct, you reserve specific ad impressions in advance, often at a fixed CPM rate. This model works well for campaigns where predictable delivery and premium placement are more important than cost efficiency.
Preferred deals
Sitting between RTB and programmatic direct, preferred deals give advertisers first access to specific inventory before it becomes available in open auctions. These arrangements offer more transparency and control than open exchanges while maintaining some of the flexibility of auction-based buying.
You negotiate a fixed price with a publisher without the guaranteed programmatic direct volume in a preferred deal. This gives you priority access to inventory at an agreed rate, but you only pay when your ads run.
Private marketplaces (PMPs)
Private marketplaces are invitation-only RTB environments where select advertisers can bid on premium inventory from specific publishers. PMPs offer greater transparency and brand safety than open exchanges while still leveraging the efficiency of programmatic technology.
Private marketplaces work particularly well for advertisers concerned about brand safety or those wanting to access premium inventory that isn’t available through open exchanges. Many publishers reserve their most valuable ad space for PMP deals with trusted advertisers.
Advanced targeting in programmatic advertising
The true power of programmatic advertising lies in its sophisticated targeting capabilities. By leveraging various data sources, you can reach precisely defined audience segments across the digital advertising space:
Demographic targeting
Basic targeting parameters include age, gender, income, education, and geography. These foundational elements help ensure your advertising inventory is shown to relevant users based on fundamental characteristics.
Behavioural targeting
Behavioural targeting examines users’ online activities, such as websites visited, searches performed, and products viewed. This approach allows you to reach people who have demonstrated interest in topics related to your offerings.
This targeting method is particularly valuable for finding users in active buying cycles. For example, a traveller researching Bali vacations can be shown relevant hotel offers, while someone reading automotive reviews might see ads for local dealerships.
Contextual targeting
Rather than focusing on the user, contextual targeting considers the web page’s content where the ad appears. This approach ensures your ads display alongside relevant content, enhancing receptivity and engagement while addressing privacy concerns associated with user tracking.
As third-party cookies phase out, contextual targeting is experiencing a renaissance. Modern contextual solutions use AI to understand page content beyond simple keywords, allowing for more sophisticated matching between ad campaigns and editorial environments.
Retargeting
Retargeting involves showing ads to users who have previously visited your website or interacted with your brand. This highly effective approach keeps your brand top-of-mind and encourages users to return and complete desired actions.
The most sophisticated retargeting strategies use sequential messaging that evolves based on user behaviour. For example, a user who abandoned a shopping cart might initially see a reminder ad, followed by a discount offer if they don’t convert within a specific time frame.
Cross-device targeting
Modern consumers move between devices throughout their day. Cross-device targeting helps you maintain consistent messaging as users switch from smartphones to laptops to tablets.
This approach relies on deterministic matching (when users log into the duplicate accounts on different devices) or probabilistic matching (using algorithms to infer relationships between devices).
Lookalike audiences
Lookalike modelling identifies users who share characteristics with your existing customers, expanding your reach to new prospects with high conversion potential. This technique leverages machine learning to identify patterns and similarities across large datasets.
For instance, if your best customers tend to visit specific types of websites, have particular interests, or exhibit certain online behaviours, lookalike modelling can find users with similar patterns who haven’t yet engaged with your brand.
Format diversity in programmatic advertising
Programmatic media buying extends far beyond traditional display banners. Today’s programmatic advertising encompasses a wide range of creative formats, each with unique advantages:
Display ads
Standard display ads remain the foundation of many programmatic campaigns. They appear in designated placements across websites and mobile apps, including familiar formats like rectangles, leaderboards, and skyscrapers.
Modern display ads have evolved from static images to include interactive elements, animations, and dynamic content that adjusts based on user data. HTML5 technology has enabled richer experiences within standard placements.
Video ads
Video ads have seen explosive growth in programmatic channels. Formats include pre-roll (before content), mid-roll (during content), outstream (within editorial content), and in-banner video ads.
Programmatic video ads benefit from precise targeting and real-time optimisation. They allow you to reach specific audiences with engaging video content across a wide range of publishers. The ability to buy video ads programmatically has democratised access to video inventory that was once only available through direct publisher relationships.
Native ads
Native advertising matches the form and function of the platforms on which it appears. These ads blend seamlessly with surrounding content, often appearing as “recommended articles” or “sponsored content.”
Programmatic native ads maintain this contextual integration while adding the efficiency of automated buying. They typically see higher engagement rates than standard display ads because they’re less disruptive to the user experience.
Audio ads
Programmatic audio enables advertisers to place ads within streaming music services, podcasts, and digital radio. This format reaches audiences during screenless moments, making it effective for branding campaigns.
Connected TV (CTV)
Connected TV advertising targets viewers watching content on internet-connected televisions and devices (like Roku, Apple TV, or smart TVs). This rapidly growing format combines the impact of traditional TV with the targeting precision of programmatic advertising.
Digital out-of-home (DOOH)
Programmatic DOOH applies automated buying to digital billboards and screens in public spaces. While still emerging, this technology allows advertisers to adjust messaging based on factors like time of day, weather, or local events.
Creating effective programmatic ad campaigns
Setting clear campaign objectives
Before launching any programmatic initiative, define specific, measurable goals that align with your broader marketing strategy. Common objectives include:
- Brand awareness: Increasing visibility and recognition among your target audience
- Consideration: Driving engagement and interest in your products or services
- Conversion: Generating direct response actions like purchases or lead submissions
- Customer retention: Re-engaging existing customers with relevant offers
Each objective requires different targeting approaches, creative strategies, and performance metrics.
Audience strategy development
A robust audience strategy forms the foundation of effective programmatic campaigns:
- Identify your core audience segments based on customer data, market research, and business objectives
- Build detailed audience profiles that capture demographics, interests, behaviours, and purchase intent
- Develop a targeting hierarchy that prioritises your most valuable audience segments
- Create a data activation plan that leverages first-party, second-party, and third-party data sources
Remember that effective audience strategies balance reach (finding new potential customers) with precision (targeting those most likely to convert).
Measurement and optimisation
Continuous measurement and optimisation separate successful programmatic campaigns from mediocre ones:
- Establish KPIs that align with your campaign objectives (e.g., viewability, click-through rate, cost per acquisition)
- Implement robust tracking across the customer journey
- Create a regular optimisation schedule to review performance and make adjustments
- Test and learn systematically by isolating variables and validating hypotheses
The real-time nature of programmatic advertising allows for ongoing refinement, but this requires commitment to data analysis and strategic adjustment.
Programmatic advertising costs
Cost per thousand impressions (CPM)
The most common pricing model in programmatic advertising is cost per thousand impressions (CPM). You pay a set amount for every thousand times your ad is displayed, regardless of user interaction. CPM rates vary widely based on targeting precision, ad format, and inventory quality.
In competitive industries or for premium inventory, CPM rates can range from $5 to $20 or higher. More general targeting and standard display formats typically command lower rates, sometimes as low as $1-3 CPM in open exchanges.
Cost per click (CPC)
With CPC pricing, you pay only when users click on your ads. This performance-focused model typically results in higher per-impression costs than CPM.
CPC bidding is less common in programmatic display than search advertising, but it can be effective for campaigns focused on driving site traffic. Typical CPC rates range from $0.50 to several dollars, depending on your industry and audience targeting.
Cost per acquisition (CPA)
The CPA model means you pay only when users complete a specific action, such as purchasing or filling out a form. This approach aligns costs directly with business outcomes but usually commands premium rates.
Some DSPs and specialised networks offer CPA-based bidding for programmatic campaigns. However, this model requires sufficient conversion data to optimise effectively.
Dynamic pricing
Most programmatic advertising operates on an auction basis, fluctuating prices based on competition for specific audiences and inventory. Your actual programmatic advertising cost depends on your bidding strategy, targeting precision, and the competitive landscape.
Additional cost factors
Several factors influence your total programmatic advertising cost:
- Data costs: Third-party audience data typically adds $0.50-$3.00 to your CPM, depending on the specificity and quality of the data.
- Technology fees: DSPs, DMPs, and verification services charge fees that can add 10-20% to your media costs.
- Creative development: Dynamic, innovative, and prosperous media formats require additional investment but often deliver stronger performance.
- Managed service fees: If you work with an agency or managed service provider, expect management fees of approximately 10-20% of your media spend.
Understanding these cost components helps you develop more accurate budgets and calculate true return on advertising spend (ROAS).
Benefits of programmatic advertising
Efficiency and automation
Programmatic advertising eliminates much of the manual work involved in buying digital media. Automating bidding, placement, and optimisation frees your team to focus on strategy rather than execution details.
Without programmatic technology, managing campaigns across dozens or hundreds of websites would require individual insertion orders, manual tracking, and countless publisher relationships. Programmatic consolidates this complexity into streamlined workflows, reducing administrative overhead by up to 80%.
Precision targeting
The ability to reach specific audience segments across thousands of websites enables more relevant ad delivery. This targeting precision reduces wasted impressions and improves campaign performance.
Unlike traditional online advertising that relies primarily on contextual placement, programmatic advertising lets you find your exact audience regardless of which websites they visit. This audience-first approach means your marketing message reaches the right people, not just the right websites.
Real-time optimisation
Programmatic platforms provide immediate performance data, allowing you to adjust campaigns on the fly. This agility ensures your ad spend is continuously redirected toward the most effective channels and audiences.
Modern programmatic systems can automatically shift budget allocation based on performance, time of day, device type, or other variables. This continuous optimisation drives incremental improvements throughout your campaign lifecycle.
Scale and reach
Programmatic advertising gives you access to vast advertising inventory across the web, including display ads, video advertising, native ads, social media ads, and in-app ads. This breadth enables you to reach your target audience wherever they spend time online.
You can access inventory across millions of websites and apps with a single programmatic campaign. This scale would be impossible to achieve through direct publisher relationships.
Transparency and insights
Advanced reporting tools provide visibility into where your ads appear, who sees them, and how they perform. These insights inform ongoing optimisation and future campaign planning.
The data generated through programmatic campaigns helps you understand which audience segments, creative approaches, and placements drive the strongest results. Over time, these insights create a competitive advantage beyond your programmatic advertising efforts.
