Impact Estimate Experiment

Introduction

Anonymised is attempting to correlate the results of the Google Ad Manager Impact Estimates with the results derived from the Google Ad Manager reporting API.

To easily enable this, we require our partners to set up a sequential set of PPID Impact Estimates over a period of 7 days.

Prerequisites

1. Ability to set up the Impact Estimates as soon as possible

2. Confirm that PPS is enabled within your GAM

3. Confirm over which Demand channels both your PPID and/or PPS signals are configured

Confirming Demand Channels for PPID and PPS

1. Within GAM360 navigate to Delivery > Demand channel settings

2. Under Default settings > Publisher data sharing, expand all settings and note the demand channels enabled for:

   1. Publisher-provided identifiers (PPID) for programmatic

   2. Publisher-provided signals: IAB audience taxonomy
      For PPS be sure to also note the signals that can be shared and the 1P scoping for Google demand
      

      

3. Send these to Anonymised

Setting up a sequence of PPID Impact Estimates

1. Set up your first PPID Impact Estimate by navigating to Optimising > Impact estimates

   1. Under Estimate options select PPID for programmatic

   2. Under Demand channel settings select Measure impact of PPID for programmatic with your current setup

   3. Leave Estimate variants as is

   4. Under Delivery settings set the first whole day for the experiment, e.g. 07 Jan 2026- 08 Jan 2026

   5. Click Run
      

      

2. Now repeat six times, one for each of the next sequential days.

3. You will now have 7 sequential PPID Impact Estimates that will run. These provide a daily view of the Google results, as the output of an Impact Estimate cannot be broken down by day for a multi-day period.
