如果您要对 Microsoft Advertising 报告指标进行自定义计算，那么自定义列将为您节省时间。通过将您的独特公式添加为自定义列，您无需再手动计算您的广告系列性能指标。
以下是一些您可以设置的自定义列的示例：
-
"桌面点击" = 点击：电脑
-
"每单位收入的成本" = 花费 ÷ 收入
-
"每美元转化" = 转化 ÷ 花费
-
"毛利率" = (收入 - 花费) ÷ 收入
您可能还想了解收入或转化率与广告的平均位置之间的关系，或者根据客户是使用电脑还是移动设备，电话呼叫次数有何变化。自定义列让您创建并显示对您有意义的数据，并使其可用于您使用的任何表格和报告。
创建自定义列
当您创建自定义列时，您可以像其他任何列一样将它们添加到表格中。请参阅自定义表格中显示的数据
自定义列可用于账户摘要、广告系列、广告组、广告&扩展和关键字页面。
-
选择要添加列的页面。例如，广告系列，广告组，或关键字。
-
在表格上方，选择 列 > 修改列 > 自定义列 > + 列。
-
输入列名和可选的描述。
-
为您的自定义公式选择性能指标。您可以使用加、减、乘、除四种运算。
-
选择您想要如何细分数据的方式。例如：设备类型、网络、顶部与其他。如果您想要查看项目的比率，请选择指标，然后选择没有数学函数的细分。
-
选择将列值格式化为数字、百分比或货币的方式。
-
选择保存。
-
在已选列下，拖放列以按您想要的顺序排列它们，然后选择应用。
您可以创建任意数量的自定义列。您可以在账户中的其他页面表格上重复使用自定义列，除了账户概览页面。同样，添加到账户概览页面的自定义列不能用于其他页面。
