Who Uses Demand-Side Platforms?

Understanding Demand-Side Platform Users

Demand-side platforms (DSPs) have become essential infrastructure in the digital advertising ecosystem, serving a diverse range of organizations that need to purchase digital advertising inventory efficiently and at scale. The primary users of DSPs are advertisers, marketing agencies, merchants, and app developers who leverage these platforms to automate their media buying processes and reach targeted audiences across multiple digital channels. Each user type brings unique requirements and objectives to their DSP usage, from brand awareness campaigns to performance-driven conversions and user acquisition strategies.

The evolution of DSPs since their emergence in the late 2000s has transformed how organizations approach digital advertising. What began as a solution for real-time bidding has expanded into a comprehensive ecosystem that supports display advertising, video, mobile in-app, connected TV (CTV), audio, and digital out-of-home (DOOH) inventory. Today, DSPs serve as the central hub for media buying decisions, enabling organizations to access thousands of publishers and ad exchanges through a single interface while maintaining granular control over targeting, bidding, and creative optimization.

Primary User Categories of Demand-Side Platforms

Advertisers and Brands

Direct advertisers and established brands represent one of the largest user segments of demand-side platforms. These organizations use DSPs to manage their own advertising campaigns without intermediaries, maintaining complete control over their media buying strategy and budget allocation. Large enterprises, mid-market companies, and growing brands leverage DSPs to reach their target audiences across multiple digital channels simultaneously, from display networks to video platforms and connected television. Advertisers benefit from the transparency that DSPs provide, allowing them to see exactly where their advertising budget is being spent and how each impression performs against their campaign objectives.

Brands using DSPs can implement sophisticated targeting strategies that go far beyond basic demographic segmentation. They can layer first-party data from their customer relationship management (CRM) systems with behavioral data, contextual signals, and lookalike audience modeling to identify and reach high-value prospects. The real-time optimization capabilities of modern DSPs enable brands to adjust their bidding strategies, shift budgets to better-performing placements, and refine their creative messaging based on live performance data. This level of control and flexibility has made DSPs indispensable for brands seeking to maximize their return on advertising spend (ROAS) and achieve measurable business outcomes.

Marketing Agencies and Trading Desks

Marketing agencies and specialized trading desks form another critical user base for demand-side platforms. These organizations manage advertising campaigns on behalf of multiple clients, using DSPs to handle the complex media buying process at scale. Agencies leverage DSPs to serve diverse client needs across different industries, budgets, and campaign objectives, from brand awareness initiatives to direct response campaigns focused on lead generation or e-commerce conversions. The ability to manage multiple campaigns simultaneously through a single DSP interface significantly improves operational efficiency and allows agencies to allocate their resources more effectively.

Agencies particularly value the data-driven insights that DSPs provide, as these insights help them demonstrate campaign performance and ROI to their clients. By using DSPs, agencies can implement best practices across their client portfolio, share learnings from successful campaigns, and continuously optimize their media buying strategies. Many agencies have built specialized teams around DSP management, developing proprietary methodologies and audience segmentation approaches that give their clients competitive advantages. The transparency and reporting capabilities of DSPs enable agencies to provide detailed performance documentation and strategic recommendations to their clients, strengthening client relationships and justifying their service fees.

E-Commerce Merchants and Retailers

E-commerce merchants and online retailers extensively use demand-side platforms to drive product sales and customer acquisition. These organizations use DSPs to reach consumers at various stages of the purchase journey, from awareness-stage prospects to high-intent shoppers actively searching for products in their category. Merchants leverage DSPs to implement retargeting campaigns that re-engage users who have visited their websites or viewed specific products, significantly improving conversion rates and average order value. The ability to target users based on their browsing behavior, purchase history, and demographic characteristics makes DSPs particularly effective for e-commerce businesses seeking to maximize their advertising efficiency.

Merchants also use DSPs to expand their reach beyond their existing customer base through lookalike audience modeling and prospecting campaigns. By analyzing the characteristics of their best customers, merchants can identify new audiences with similar profiles and purchase intent, enabling them to acquire new customers at scale. The performance-focused nature of e-commerce advertising means that merchants prioritize DSPs that offer robust conversion tracking, attribution modeling, and optimization algorithms that can maximize return on ad spend. Many e-commerce businesses integrate their DSP campaigns with their inventory management systems, allowing them to adjust bidding strategies based on product availability and profit margins.

App Developers and Mobile-First Companies

App developers and mobile-first companies represent a rapidly growing segment of DSP users, particularly those focused on user acquisition and retention. These organizations use DSPs to promote their mobile applications across app stores, in-app advertising networks, and mobile web properties. App developers leverage DSPs to reach users who are most likely to download their applications, engage with their content, and generate revenue through in-app purchases or advertising. The mobile-focused DSPs in the market offer specialized features for app promotion, including integration with mobile measurement partners, app store optimization data, and user lifecycle management capabilities.

App developers use DSPs to implement sophisticated user acquisition strategies that go beyond simple install campaigns. They can segment users based on their likelihood to become high-value players, implement retention campaigns targeting users at risk of churn, and optimize their spending across different user cohorts based on lifetime value predictions. The real-time bidding capabilities of DSPs allow app developers to adjust their bids dynamically based on user quality signals, ensuring they acquire users at the most efficient cost per install. Many app developers use multiple DSPs simultaneously to maximize their reach and compare performance across different platforms, allowing them to identify which DSPs deliver the highest-quality users for their specific applications.

Detailed User Profiles and Use Cases

How Different User Types Leverage DSP Features

Targeting and Audience Segmentation

Different DSP users prioritize different targeting capabilities based on their business models and campaign objectives. Direct advertisers and agencies often focus on sophisticated audience segmentation that combines multiple data sources, including first-party CRM data, behavioral signals, contextual information, and third-party audience data. They use DSPs to create highly specific audience segments that represent their ideal customer profiles, enabling them to deliver personalized messaging to users most likely to convert. E-commerce merchants particularly value retargeting capabilities that allow them to re-engage users who have shown interest in specific products, implementing sequential messaging strategies that guide users through the purchase journey.

App developers prioritize mobile-specific targeting capabilities, including device type, operating system, app category preferences, and user lifecycle stage. They use DSPs to implement lookalike modeling based on their existing user base, identifying new users with similar characteristics and predicted lifetime value. The ability to target users based on their predicted likelihood to become high-value players allows app developers to optimize their user acquisition spending and focus their budgets on the most valuable user segments. Marketing agencies often develop proprietary audience segmentation methodologies that they apply across their client portfolio, creating competitive advantages through superior targeting precision and audience insights.

Real-Time Optimization and Bidding Strategies

DSP users leverage real-time optimization capabilities to maximize their campaign performance and return on investment. Direct advertisers and agencies use DSPs to implement dynamic bidding strategies that adjust bid amounts based on user characteristics, contextual signals, and predicted conversion likelihood. The machine learning algorithms embedded in modern DSPs can analyze millions of data points in real-time, identifying patterns that indicate high-value impressions and automatically adjusting bids to maximize efficiency. E-commerce merchants use DSPs to implement bid strategies that account for product profitability, inventory levels, and seasonal demand fluctuations, ensuring their advertising spending aligns with their business objectives.

App developers use DSPs to implement cost-per-install (CPI) bidding strategies that optimize for user quality rather than simply minimizing acquisition costs. By setting target cost-per-install levels and allowing the DSP’s algorithms to optimize toward those targets, app developers can ensure they acquire users at efficient costs while maintaining quality standards. Marketing agencies often implement custom bidding strategies tailored to their clients’ specific objectives, whether those objectives are brand awareness, lead generation, or direct sales. The transparency that DSPs provide into bidding decisions and impression-level performance data enables agencies to continuously refine their strategies and demonstrate the value they deliver to their clients.

Data Integration and Attribution

Modern DSP users increasingly recognize the importance of integrating DSP data with other marketing and business systems to gain comprehensive insights into campaign performance and customer journey. Direct advertisers and agencies use DSPs that offer robust data export capabilities and API access, allowing them to integrate DSP data with their data warehouses, business intelligence tools, and marketing automation platforms. This integration enables them to analyze how DSP campaigns influence downstream business outcomes, including lead quality, sales pipeline progression, and customer lifetime value. E-commerce merchants integrate DSP data with their e-commerce platforms, inventory management systems, and customer analytics tools to understand how programmatic advertising influences their overall business performance.

App developers integrate DSP data with mobile measurement partners and attribution platforms to track how their DSP campaigns influence app installs, user engagement, and in-app revenue. This integration allows them to implement sophisticated attribution models that account for multiple touchpoints in the user acquisition journey, ensuring they accurately measure the contribution of their DSP campaigns. Marketing agencies increasingly use data integration platforms that unify DSP data with other marketing channel data, enabling them to provide clients with comprehensive cross-channel attribution and performance analysis. This capability to integrate and analyze data across multiple sources has become a key differentiator for agencies seeking to demonstrate their value and justify their service fees.
