Global Programmatic Advertising: Trend, Ecosystem and Practical Guide

The global advertising market is approaching the trillion-dollar mark, with programmatic buying firmly established as the mainstream. For globalizing advertisers and programmatic platforms, understanding market dynamics is key to success.

I. Inevitable Trend: Programmatic Advertising in the Trillion-Dollar Market
Per eMarketer's 2025 forecast, global advertising spending will exceed $1 trillion for the first time in 2025, with digital advertising as the growth engine and programmatic advertising as its core driver. Dentsu's 2024 report notes that $7 out of every $10 in digital advertising investment goes to programmatic; in mature markets like Europe and the U.S., 85-90% of digital ad spending uses programmatic, and this proportion will rise to 90% globally (95% in Europe and the U.S.) by 2025.
Regional growth highlights: The Middle East and Africa (+33.1%), Western Europe (+15%), and Central and Eastern Europe (+12.5%) are the fastest-growing regions; U.S. programmatic spending will exceed $150 billion in 2025, with China close behind. Growth has expanded beyond traditional display and video to Connected TV (CTV), Digital Out-of-Home (DOOH), and gaming consoles.

II. Ecosystem Analysis: Characteristics of Overseas Programmatic Advertising
Compared with the domestic market, the overseas programmatic ecosystem has unique features that bring both challenges and opportunities.
1. Diversified Traffic Sources
Overseas traffic covers mobile Web, desktop Web (critical for B2B and high-value conversions), CTV (explosive growth for household audience engagement), and DOOH (integrated with geographic data for offline precision). This requires platforms to integrate multiple traffic types. Overseas DSP budgets are also diverse, with specializations in CTV or niche regional markets (e.g., Japan, South Korea, Latin America).
2. Unified Technical Standards and Transparent Supply Chains
Overseas markets adopt global open standards (e.g., IAB Tech Lab), enabling efficient integration (unified protocols reduce integration costs) and transparent supply chains (clear norms curb ad fraud and improve budget efficiency).
3. Independent Third-Party Measurement
Providers like AppsFlyer, Adjust, and IAS offer objective performance measurement, enhancing trust among advertisers, media owners, and platforms. This open, standardized ecosystem provides great opportunities for domestic platforms to expand globally.

III. Practical Guide: Programmatic Advertising's Value for Global Business
1. Core Value: From "Buying Ad Space" to "Buying Audiences"
- Precise Targeting & Real-Time Optimization: DMP-based user profiles enable niche audience targeting; algorithms optimize bidding and creatives in real time.
- Cost Efficiency & Transparency: Programmatic bidding eliminates manual negotiations, enabling market-driven pricing and full budget visibility.
- Cross-Channel Integration: Unifies mobile, desktop, and CTV for coordinated campaigns; smart frequency capping optimizes reach.
- AI Innovation & Privacy Compliance: AI technologies (e.g., differential privacy) balance targeting and compliance with GDPR/CCPA; AI also automates creatives and conversion prediction.
2. Technical Foundation: The "Four Pillars"
- DSP: Advertiser's command center for budget setting, targeting, and automated bidding.
- SSP: Media owner's tool to optimize ad inventory and connect with DSPs.
- Ad Exchange: Links DSPs and SSPs for real-time bidding (RTB).
- DMP: Integrates multi-source data to build user profiles for precise targeting.
