您正在合作的一位客户想要投资一个长效的第一方数据策略。 您应该告诉他们做些什么？

The correct answer emphasizes a proactive approach to first-party data collection by optimizing the user experience. By making the email address request more prominent and earlier in the landing page strategy, the client can significantly increase the volume of collected email addresses, which are a cornerstone of a strong first-party data strategy. Collecting device IDs is a short-term workaround for third-party cookie deprecation, not a long-term first-party data strategy. Increasing investment in third-party data products contradicts the goal of building a first-party data strategy. While offering strong incentives can help, simply offering incentives without optimizing the collection process (like the landing page strategy) may not be as effective in the long run for sustained data growth.
