Avoiding overlapping values in reports

Note: This topic applies to reports created using Reports in the Index UI The Index UI at app.indexexchange.com that allows you to manage integration settings, such as inventory, campaign, and deal settings. and the Reporting API An Index product that provides aggregated reporting data that can be delivered through email, Amazon S3 bucket, or pulled through the API. The Reporting API allows customers to create their own customized reports and schedule their automated delivery..

Metrics like ad spend and impressions can show inaccurate totals when summed. This is because a single event, for example an impression, can be associated with multiple dimension values, for example multiple targeted segments. As a result, if you perform any summing to your reports, you may see incorrect totals.

We recommend that you avoid performing any additional summing on your end to the metrics in our reports.

An example: A deal targets two segments on the same impression

An article on a Media Owner's site titled "Predictions for the Superbowl" matches a deal A private auction that allows media owners to offer specific inventory directly to selected buyers identified by a deal ID. Terms are negotiated and are agreed upon before the auction occurs. that targets the following segments:

• Sports Enthusiasts

• Pet Owners

Any impression that matches both targeted segments can show up in reporting, in the segment_name field, with multiple associated segment values, for example:

If the Media Owner sums their report, they'll see 1,000 impressions instead of 500, which is the true number.
