What is Incrementality? How is Incrementality used for attribution in Audio campaigns?

Audio incrementality is a method to measure the additional conversions or sales that can be attributed to your audio ad campaigns, beyond what would have occurred without them. It helps determine the true value of your audio ads in driving incremental results.

Ghost ads are a popular industry technique used to measure incrementality. They are essentially "placebo" ads, which means they mimic the actual audio ad but do not contain any promotional content. Here's how ghost ads work to measure incrementality:

  1. Test and control groups: Your target audience is divided into two groups - a test group that receives your actual audio ads and a control group that receives the ghost ads.
  1. Ad delivery: Both groups are served their respective ads through programmatic audio platforms across various channels like podcasts, streaming radio, and music services.
  1. Tracking and data collection: Unique identifiers or tracking pixels are embedded in both the actual and ghost ads to track user interactions and conversions.
  1. Comparing results: After running the ad campaign for a predetermined period, the conversions and interactions from both groups are compared. Since the control group received ghost ads with no promotional content, any difference in conversions between the two groups can be attributed to the actual audio ads.
  1. Calculating incrementality: The incrementality lift percentage is calculated by dividing the difference in conversions between the test and control groups by the total number of conversions in the control group. This percentage represents the additional conversions that can be credited to your audio ad campaign.

In summary, audio incrementality using ghost ads is a method to quantify the true impact of your audio ad campaigns on driving incremental results. This approach provides valuable insights that can help you optimize your marketing strategies and maximize the effectiveness of your audio advertising efforts.
