Best practices and tips for reporting

  • Use filters to surface data quickly. For example, running your report for a single order or a group of orders at a time will make the report run faster, especially if the publisher has a large number of orders.
  • Use shorter date ranges where applicable.
    Limit the date range of your reports
    A broad date range selection, such as the dynamic date range of "Last 3 years", may unfavorably impact your report performance. We strongly recommend that you choose a specific date range whenever possible.
  • Any saved, scheduled, or API report running for over an hour is automatically terminated. We recommend that you run multiple smaller reports to avoid this limitation.
  • A maximum of 100 rows are displayed on the report results page. If your results are over 100 rows, we recommend that you export your data.
  • Reports with high row counts that include large numbers of dimensions and/or metrics may fail to export successfully in available formats. If this occurs, reduce the complexity of the report by including fewer dimensions and/or metrics or shortening the date range. Then try exporting again. 
  • For speedier reports, be sure to select the Flat view as your default in report preferences. 
  • To save you time, you can use the Run Now link to execute a report directly from the Reports overview page without having to first load the report.
  • Create and schedule reports that are needed on a regular basis—this reduces set up time and waiting for reports to render in the user interface.

Dimensions and metrics

  • Ad Manager reporting provides a wide variety of dimension and metric combinations. However, the reports can't offer every combination. If some fields appear grayed out after you select a dimension or metric, it indicates that those metrics can't be combined.
  • You can add up to ten dimensions in a report. There is no hard limit on the number of metrics you can add to a report.

    Be aware that the complexity of a report increases as you add more dimensions and metrics. The chances of latency or failure to run increases with complexity, therefore we strongly recommend that you limit the number of report criteria.
  • Exclude unneeded metrics from your reports to improve performance.

Historical Reports

  • Total and Unfilled impressions: Unfilled impressions are ad requests that didn't return an ad and mean that no line item was eligible to serve. This can be avoided by having some widely targeted (run-of-network) ads like house ads or AdSense or Ad Exchange always running in your network. Unfilled impressions are not included in the Total impressions count. 

Report scheduling

  • If you schedule an existing report for "Daily", you receive a copy of the report tomorrow in the network time zone.
  • When you run a report for a long time period (for example, last 6 months, or quarter to date), the report may stop working due to the complexity of the criteria. As time passes, the amount of your data increases, which in turn surpasses the limitations of Ad Manager reporting. To work around this issue, you can:
    • Run multiple reports for smaller time frames.
    • For scheduled reports, a "start date" and an "end date" are required.
    • Scheduled reports must end within 1 year of the start date.
