  • Optimizing: You can identify areas where you may have inefficiencies and use data to increase your performance.

  • Alerting: You can identify when specific KPIs pass their SLAs or thresholds, and then notify key stakeholders.

  • Troubleshooting: You can quickly drill into problems, identify root causes, and fix them.

  • Revenue reporting and billing: You can track ad spend activity throughout the month with reporting.

Reporting services

Index provides access to reporting data through the Index UI and through the Client Audit Logs (CAL) API.

Index UI

Note: Reports in the Index UI is currently in closed Beta for buyers. For more information, contact your Index Representative.

You can use the Index UI to create, schedule, and manage your own reports. Building reports in the Index UI is designed for users who want to easily create and manage their reports through a user friendly UI. For more information, see Reports in the Index UI (Beta).


The Client Audit Logs (CAL) API allows you to retrieve raw log files for impression and bid events through the API. It requires a more technical setup and maintenance on your end, but provides you with the freedom to build out your own reporting solution. This solution is best for buyers with engineering resources. For more information, see Client Audit Logs (CAL) API.
