Reporting Metric Description
Total Impressions The total number of impressions your line item has made

- Audience Share (%) = Row Level Audience Count ÷ Campaign Total Audience Count × 100
On Target Percent (%) The percentage of impressions served to your targeted demographic
- On Target Percent (%) = Impressions Seen by Target Demographic ÷ Total Impression Count for your Line Item × 100
Unique Audience The number of unique individuals in the audience that your line item reached
On Target Impressions The number of impressions served to your desired demographic group that are within your selected reporting dimensions
Population Share (%) Percentage of people within a demographic relative to the total population
- Population Share (%) = Demographic Population ÷ Population of all Demographics × 100
Impressions Share (%) Based on the line item's total impression count, the percentage that served to your targeted demographic
- Impressions Share (%) = Demographic Impressions ÷ Total number of Impressions Across all Demographic Groups × 100
Population Based on census-provided data, the number of people in the country included in a given demographic
- Example: F18-24 = 14.9 million

To Run your report

Follow these steps to run the report:

  1. Select Reporting > Advertiser Reports from the dropdown menu (depending on how your account has been configured).

  2. Select the relevant report from the list. The Report screen shows the available filters, dimensions, and delivery options for the report. Theselections you make here will determine what report data is delivered to you, and how.


    For an explanation of how grouping and filtering work see Dimensions, Metrics, Filtering, and Grouping.

  3. Select the relevant filters to limit the data displayed to just the information you want. For example, rather than running a report that shows impressions for all inventory sources, you may want to list results for just a select few. When you select a filter (by clicking Edit), a selection panel appears. Select items in the Available list (left), then click Add to include them in the Chosen list (right).

  4. Group by Dimension. Grouping allows you to display rows of data in the order you prefer.


    The more dimensions you group by, the larger the data set that is returned. Larger data sets can take substantially longer to process. Be sure to group using only the dimensions you need.

  5. Choose a delivery option. Once you've selected your filters and grouped by your chosen dimensions, you need to choose a delivery method. Available delivery methods include:

    • Run now, show results in screen: For smaller amounts of data, you may want to view the report as soon as possible in your browser.
    • Run in background, notify me when results are ready to view: A pop-up notification will let you know when the report is ready to view or download.
    • Export, send results via email: Run the report in the background and email the results to one or more email addresses.
    • Save as report template: Save your selected report settings so that you can run this report again in the future. You can name this template using the text entry field under Name this report (its checkbox is auto-selected when you choose this option). A saved report can be rerun from the Your Reports screen.
    • Add to scheduled reports: Run this report automatically at specified times and have it sent to one or more email addresses.
    • Name this report: Give this report with its current settings a name for future reference.
  6. Click Run report to send your report request.
