The advertising market is undergoing a profound transformation, driven by technological evolution and changes in consumer habits. Artificial Intelligence, the integration of DSP and SSP or ACR (Automatic Content Recognition) technology in Smart TVs are some of the key aspects that the Top Digital Trends 2025 Report highlights for the advertising industry this year. In this constantly changing landscape, programmatic advertising remains a fundamental pillar for the future of digital advertising. However, to fully exploit its potential, the sector must face several key challenges that require a strategic and forward-looking approach. Experts from PubMatic, an independent technology company that offers the digital advertising supply chain of the future, outline the 7 challenges that the ad-tech landscape must address to ensure an efficient, transparent and sustainable advertising ecosystem, taking advantage of the opportunities offered by the evolution of programmatic advertising. 7 challenges facing the industry: Measurement and standardisation The lack of standard metrics across traditional platforms and programmatic advertising is a barrier to cross-platform campaigns. Collaboration within the industry is needed to develop unified measurement systems applicable to both TV and digital platforms. Transparency and trust in data Data quality and transparency are crucial. The industry must adopt standardised data management practices and transparent measurement tools to improve attribution models and ensure accurate reporting of both advertising spend and results. Integration of traditional and programmatic systems Integrating traditional TV advertising currencies with programmatic requires collaboration that balances innovation with existing infrastructure, while ensuring efficiency and quality of content. Scalability and market fragmentation Fragmentation of the programmatic ecosystem makes scalability difficult. Companies must invest in technology solutions that facilitate data sharing and integration, overcoming local inconsistencies and regulatory complexities. Supply Chain Optimization (SPO) and Curation Widespread adoption of Supply Chain Optimization (SPO) will bring multiple benefits: a more agile and transparent programmatic supply chain, improving control over advertising spend by eliminating unnecessary intermediaries. This will lead to more efficient programmatic buying, providing advertisers with better access to premium, high-quality, fraud-free and brand-safe inventory. This will improve targeting and advertising effectiveness, and reduce unnecessary costs, while increasing reach. Transition from CTV to Programmatic The shift from traditional insertion orders (IO) to programmatic in connected TV (CTV) is crucial for the future of TV advertising. While IO-based and programmatic models will coexist in the short term, broadcasters must adopt programmatic solutions to remain competitive. This transition will deliver better targeting, broader audience coverage and more effective frequency control across CTV publishers, allowing advertisers to fully capitalise on the effectiveness of programmatic without compromising content quality. As CTV grows, broadcasters will need to adapt, integrating programmatic advertising without losing the premium value of their content. Sustainability Adtech will need to reduce its environmental impact, optimising data centre efficiency and investing in sustainable infrastructure and renewable energy sources. Transparency on the carbon footprint of digital campaigns will become increasingly important, forcing the industry to measure and report its emissions. With the growing focus on sustainability from brands and consumers, adtech will need to adopt responsible practices across the supply chain, bringing a range of benefits including reduced waste, optimised delivery, improved overall efficiency of programmatic processes and, not least, increased consumer trust. Miguel Fernández-Gil, Country Manager, Spain, at PubMatic, says that “the advertising market is undergoing a profound transformation, driven by technological evolution and changing consumer habits. In this ever-changing landscape, programmatic remains the cornerstone of the future of digital advertising. However, to take full advantage of the opportunities available to advertisers, it is essential to have a clear vision of the future of digital advertising.
