Custom columns in Search Ads 360 offer a powerful way to tailor your reports for
deeper analysis. You can track specific conversion actions across platforms,
compare performance across devices, analyze keyword performance, monitor
campaign budgets, and even calculate ROI for different campaigns or keywords.
Types of custom columns
The Search Ads 360 Reporting API supports two types of custom columns:
Custom formula columns enable you to write formulas using spreadsheet
features, such as functions and filters, directly in Search Ads 360.
Custom conversion columns enable you to report on specific conversion actions.
How to add custom columns to your reports
You can include custom columns in your queries in the same way as you include
fields and metrics, using their ID. The syntax to use is
custom_columns.id[1234].
