As a result, advertisers must shift towards first-party data, contextual advertising, and machine learning-driven insights to maintain ad performance while complying with privacy-first policies.
Businesses that fail to adapt risk declining ad effectiveness, rising customer acquisition costs, and limited audience insights.

- Google’s Privacy Sandbox: Google is developing privacy-first alternatives to third-party cookies. These include:
- Topics API: Replaces cookie-based tracking with broad interest categories.
