DSP (Demand-Side Platform)

1.Definition: What is DSP?

2.Core Value of DSP

• Cross-Platform Traffic Integration: Breaks down media silos, providing one-click access to tens of thousands of media resources (including websites, apps, videos, etc.).
• Precision Targeting: Combines multi-dimensional tags such as user behavior data, geographic location, and device type to achieve targeting accuracy of over 90%.
• Real-Time Bidding Efficiency: Completes bidding decisions for a single ad impression in less than 100 milliseconds, 1,000 times more efficient than traditional manual negotiations.
• Cost Control Advantage: Supports multiple billing models like CPM, CPC, and CPA, dynamically optimizing bidding strategies through algorithms.

3.Technical Architecture of DSP

• Data Access Layer: Connects to DMPs to obtain user profiles and links to ad exchanges to access traffic pools.
• Decision Engine:
  • Real-Time Bidding Module (RTB Engine)
  • Machine Learning Models (predicting click-through rates/conversion rates)
  • Budget Allocation Algorithms (based on ROI goals)
• Delivery Management:
  • Cross-Device ID Mapping (resolving user identification across multiple devices)
  • Frequency Control (preventing overexposure to the same user)
  • Dynamic Creative Optimization (DCO)

4.Advanced Applications of DSP

• Audience Strategy: Build hybrid modeling using first-party data (CRM data) combined with third-party data (interest tags).
• Bidding Strategy: Bid Price = Target CPA × Predicted Conversion Rate + Adjustment Factor
• Creative Testing: Use an A/B/n testing framework to run dozens of creative versions simultaneously.
• Anti-Fraud Mechanisms: Deploy IVT (Invalid Traffic) detection to filter out fraudulent traffic.

5.Industry Evolution Trends

• OTT/CTV Advertising: Programmatic ad purchases on smart TVs have seen a 67% year-over-year growth (2023 IAB data).
• Privacy Computing: Federated learning-based joint modeling solutions are gradually replacing cookie tracking.
• AI-Generated Creatives: Tools like Stable Diffusion enable real-time generation of personalized ad materials for thousands of users.
