若想制定能保護隱私權的全漏斗行銷策略，以下何者是推薦的方法？

The recommended approach for a privacy-safe full-funnel marketing strategy is to implement a comprehensive strategy as advised, then iteratively refine it by removing the least effective tactics. This allows for data-driven optimization while maintaining a broad reach initially. The other options are less effective because: Focusing only on bottom-funnel tactics (Option 1) neglects awareness and consideration stages, limiting overall growth. Starting with only mid-funnel tactics (Option 2) assumes users are already aware, missing potential customers at the top of the funnel. Activating all tactics indiscriminately (Option 3) without a strategic hypothesis is inefficient and can lead to wasted resources without clear privacy considerations.
