Demand-Side Platforms (DSPs) are at the heart of programmatic advertising, enabling advertisers to automate and optimize their media buying. However, the role of DSPs is rapidly evolving, bringing significant changes that directly impact publishers. As we enter 2025, DSPs are shifting towards artificial intelligence (AI), privacy-compliant advertising, new formats like connected TV (CTV), and more selective supply paths.
For publishers, understanding these trends is crucial to staying competitive in a landscape where DSPs are becoming more sophisticated in how they evaluate and purchase inventory. This article explores the key changes shaping DSPs in 2025 and how publishers can adapt to maximize revenue.
AI-Driven DSPs and Predictive Bidding
Machine learning and AI are transforming DSPs from basic automated bidding platforms into predictive intelligence engines. Instead of reacting to bid opportunities in real time, DSPs now use AI to analyze patterns and anticipate user behavior, leading to more efficient bidding.
AI-driven DSPs optimize media buying by:
- Analyzing massive datasets to predict the likelihood of user engagement
- Adjusting bid strategies based on historical performance and contextual signals
- Reducing wasted ad spend by ensuring bids are placed only when there is a high probability of conversion
How This Affects Publishers
- AI-driven bidding results in more precise ad placements, increasing the value of impressions
- Higher accuracy in targeting leads to better engagement rates and improved CPMs
- Publishers with high-quality, engaged audiences will benefit the most from this shift
Privacy-First Advertising and the Shift to First-Party Data
With third-party cookies being phased out, DSPs are turning to privacy-friendly alternatives such as contextual targeting, first-party data, and new identity solutions.
Key privacy-driven changes in DSPs:
- Greater reliance on first-party data from publishers
- Increased use of contextual targeting to match ads with page content rather than user behavior
- Adoption of privacy-compliant identifiers such as Google’s Privacy Sandbox and Unified ID solutions
How This Affects Publishers
- Publishers who collect and leverage first-party data can secure higher bids from DSPs
- Contextual targeting ensures content relevance becomes a key factor in ad pricing
- Transparent SSPs like WaardeX help publishers connect their first-party data with DSP demand
The Growth of Connected TV (CTV) and Audio DSPs
The fastest-growing segments in programmatic advertising are CTV and digital audio. DSPs are expanding beyond traditional display and video ads to support programmatic TV, podcast ads, and even in-game advertising.
This shift presents new monetization opportunities for publishers, especially those with video content.
How This Affects Publishers
- CTV and video inventory are becoming premium assets, with higher CPMs than standard display ads
- Publishers who expand into interactive and immersive ad formats will gain a competitive advantage
- SSPs like WaardeX enable publishers to connect their video and audio inventory to high-paying DSPs
Supply Path Optimization (SPO) is Reshaping DSP-Publisher Relationships
As the programmatic landscape matures, DSPs are becoming more selective in how they source inventory. Supply Path Optimization (SPO) is now a priority, meaning DSPs favor direct, efficient, and transparent supply routes over complex chains of intermediaries.
How This Affects Publishers
- Direct relationships with top DSPs will become more valuable than working through multiple resellers
- Low-quality traffic sources will be deprioritized, making transparency a key differentiator
- SSPs like WaardeX help publishers streamline inventory and maintain high-quality connections to DSPs
Industry Insight: The Future of DSPs and Publisher Revenue
According to eMarketer, global programmatic ad spending through DSPs is expected to exceed $250 billion by 2026, with AI-driven buying accounting for over 60% of total programmatic transactions. Additionally, IAB’s 2024 report indicates that 80% of advertisers plan to increase investments in first-party data partnerships, highlighting a shift towards publisher-controlled audience insights.
This transformation means publishers must adapt to changing DSP strategies by focusing on high-quality inventory, first-party data, and direct connections with premium demand sources to remain competitive.
Conclusion
DSPs are evolving rapidly, and publishers who adapt will have a significant advantage. With the right technology, data strategies, and SSP partnerships, 2025 can be a breakthrough year for revenue growth. Publishers who embrace AI-driven bidding, invest in first-party data, and streamline supply paths will be in the best position to maximize demand and CPMs.
