请翻译成英文 在常规性分析中，我们首先会聚焦在用户增长的策略效率上，按照不同场景（如内容场景及货架场景），不同目的（如拉新、复购、召回）的策略，分别从用户价值、策略效率以及规模三个角度进行分析，从而提出针对不同策略扩大投入或减少投入的建议，从而不断提高效率

In regular analysis, our focus is first on the efficiency of user growth strategies. We analyze different strategies for various scenarios (such as content and shelf display scenarios) and different objectives (such as acquisition, retention, and recall) from three perspectives: user value, strategy efficiency, and scale. We then provide recommendations for increasing or decreasing investment for different strategies to continuously improve efficiency.
