您的客户希望为 Chrome 弃用第三方 Cookie 做好准备。 应采取哪两个步骤？ 请选择两项。

To prepare for Chrome's deprecation of third-party cookies, clients should focus on building a sustainable, privacy-centric infrastructure and leveraging advanced AI solutions. Building a sustainable infrastructure involves implementing site-wide tagging, utilizing Google Analytics 4 (GA4) for robust first-party data collection and insights, and employing Customer Match for audience activation based on first-party data. This approach reduces reliance on third-party cookies. Additionally, leveraging Google AI through solutions like Optimized Targeting helps identify and reach relevant audiences without depending on individual third-party cookie data, improving campaign effectiveness in a privacy-enhanced environment. Adopting a "wait and see" approach is reactive and risks falling behind competitors. While Privacy Sandbox APIs are relevant, they are still evolving, and the other two options represent more immediate and actionable steps for preparation.
