Gamera Signals for AdX Optimization

Last updated: June 16, 2026

This document outlines an emerging capability designed to enhance AdX yield performance through the strategic use of Gamera key-value pairs. By passing inventory quality signals - such as high viewability or CTR rates - directly into Google Ad Exchange, publishers can optimize AdX demand more effectively, resulting in measurable improvements to overall yield.

Early adopters of this test have reported material increases in AdX revenue, suggesting meaningful opportunity for publishers seeking to extract greater value from their existing inventory.

Setup

Step 1: Gamera Signals

For optimal results, we recommend configuring the following signals using a combination of CTR and Viewability metrics. All other metrics within the signals should be adjusted to the least restrictive setting possible to maximize delivery against these targeted data points.

  1. AdX Test - Tier 1 CTR/Viewability

    1. CTR: >.25% - 10%

    2. Viewability: 80 - 100%

  2. AdX Test - Tier 2 CTR/Viewability

    1. CTR: > .15% - 10%

    2. Viewability: 70 - 100%

  3. AdX Test - Tier 1 CTR

    1. CTR: > .25% - 10%

  4. AdX Test - Tier 2 CTR

    1. CTR: > .15% - 10%

  5. AdX Test - Tier 1 Viewability

    1. Viewability: 90 - 100%

  6. AdX Test - Tier 2 Viewability

    1. Viewability: 80 - 100%

  7. AdX Test - Tier 3 Viewability

    1. Viewability: 70 - 100%

  8. AdX Test - Tier 4 Viewability

    1. Viewability: 60 - 100%

Note: for these tests to be viable, they must have a minimum of 100k impressions/day

Step 2: AdX Line Items

  1. Ensure that you have a single RON AdX line item with no Gamera related key-value targeting to use as a benchmark for this test

  2. Create:

    1. One AdX line item to correspond to each Gamera signal associated with this test (created in Step 1). Configure the targeting to the Gamera KVP, i.e. gamera=gamera_123

    2. One RON line item negatively targeting all Gamera signals associated with this test (created in Step 1).

Validation

  1. Set the Gamera KVPs to reportable

  2. Allow the test to run for a minimum of 14 days
