您的客户希望使用自定义列来定义和查看其 Google Ads 数据的特定部分。 在 Search Ads 360 中，该客户可以使用哪两种类型的自定义列？

The correct answer is "自定义公式和自定义转化" (Custom formula and custom conversion). Search Ads 360 allows users to create custom columns using these two types to tailor data views. Custom formula columns enable calculations based on existing metrics and dimensions, offering flexible data analysis. Custom conversion columns allow users to define and track specific conversion actions that are not standard Google Ads conversions, providing more granular insights into user behavior and campaign performance. "自定义维度" (Custom dimension) is not a type of custom column in Search Ads 360; it's a concept more related to analytics platforms for categorizing data. "自定义标签" (Custom label) is used for organizing campaigns, ad groups, or keywords, not for creating custom data columns.
