Pay-per-click Model

The Pay-per-click (PPC) model is a digital advertising framework where advertisers pay only when their ads are clicked. Under the GDPR's General Data Protection Regulation, particularly Article 6 (Lawfulness of processing) and Article 21 (Right to object), the use of personal data for targeting in a PPC model requires explicit user consent. ISO/IEC 27701 provides the necessary framework for managing personal data within these advertising processes, ensuring that click-based data--such as IP addresses, device IDs, and browsing history--is handled according to privacy principles. Unlike Cost-per-mille (CPM) models, PPC relies heavily on user-specific engagement data, making it highly sensitive to privacy regulations. This creates a tension between advertising effectiveness and regulatory compliance that must be managed through robust Information-- and Privacy--Management Systems (IPMS).

Implementing a PPC model within an enterprise risk management framework involves three critical steps: First, conduct a Data Protection Impact Assessment (DPIA) as mandated by GDPR Article 35 to identify risks associated with click-based data collection. Second, deploy a Consent Management Platform (CMP) to manage user permissions in real-time, ensuring compliance with ISO/IEC 27701 controls. Third, implement data--centric security measures, such as pseudonymization, to protect user identities during the bidding process. A real-world example is a Taiwanese e-commerce retailer that integrated a GDPR-compliant CMP across its EU-facing website, resulting in a 30% increase in consent rates and a 15% reduction in privacy-related complaints within six months. The key KPI is the ratio of compliant click-to-conversion, which should be monitored quarterly to ensure ongoing compliance and ROI optimization.

Taiwan enterprises typically face three challenges: first, the complexity of cross-border data transfer regulations (GDPR vs. Taiwan Personal Data Protection Act); second, the technical difficulty of implementing privacy-preserving ad-tech; and third, the lack of internal expertise in privacy engineering. To overcome these, enterprises should: 1. Establish a Privacy-First Marketing Strategy, prioritizing first-party data--over third-party cookies-to mitigate the impact of browser-level privacy changes. 2. Invest in ISO 27701 certification to demonstrate international compliance, which is crucial for EU market access. 3.
