TV Attribution Outcomes Vary Widely Among Providers Due To Inconsistent Data Inputs

CIMM/4A’s report says methodology, rather than technology, is root cause of TV attribution outcome differences; calls for more stringent media measurement standards 

New York, NY (September 23, 2020) – The inconsistency of key television attribution inputs used by providers, not technology, is the main cause of variance in outcome measurements, according to a report issued today by the Coalition for Innovative Media Measurement (CIMM), in conjunction with the 4A’s Media Measurement Task Force.

The analysis, which looked at the practices of eleven leading TV attribution providers, found that more stringent media measurement standards are required to ensure attribution results that are consistent and comparable from provider to provider, with exposure data, more than occurrence data having the biggest impact on outcome results. The report calls for the addition of standardization, such as commercial IDs similar to Ad-ID, for identifying occurrences and in defining exposure and reach.

“Getting Attribution Right: An Exploration and Best Practices for Television Data Inputs in Attribution Modeling,” was presented as part of The ARF’s AudiencexScience virtual event.  The study was conducted by Sequent Partners and Janus Strategy and Insights and was designed to define best practices for better representation of television in attribution models. It is the fourth white paper in a series commissioned by CIMM and 4A’s examining TV attribution and was structured around two main variables: key inputs of ad schedules and ad exposures across attribution providers.

Additional findings include:

  • Occurrences and exposure data are highly inconsistent across providers: The accuracy of spot detection and all of the different exposure data elements—GRPs, Reach, Frequency—differ from provider to provider. Identifying and the counting of exposures, or impressions, should be standard starting points. How providers then connect the dots from exposures to outcomes should be their points of difference. If they are all identifying different occurrence levels and evaluating different exposures, then they may as well be evaluating different campaigns.
  • Lift outcomes differ significantly: Because of the differences in both occurrence and exposure data, measurement of lift provider to provider yielded different results, both in terms of magnitude and direction of lift.
  • Provider exposure data impacts lift results more than occurrence data: The study found that while there are differences between providers for both occurrence data and exposure data, the differences in exposure data are a much larger contributor to differences in lift measurement.
  • Methodology, rather than underlying technology, drives results: For both occurrence data and exposure data, the underlying data elements—monitoring of network signals to create an accurate ad occurrence file, ACR and/or set-top box data that measures what households are viewing—are similar. The methodology of converting that data into final ad occurrence files and exposure data, including weighting, editing and other data processing rules, is believed to be the cause of the differences between providers.

“Earlier this year, we set out to uncover what drives the difference in attribution results across industry attribution providers, each offering varying approaches, including relying on different modeling techniques and data sources,” said Alice K. Sylvester, partner, Sequent Partners. “While the findings of our study do not necessarily tell us how to solve for the attribution inconsistencies our industry currently faces, they do clearly indicate the need for the standardization of naming, definitions, and categorization and more careful quality assurance procedures.”

“In order to bring more transparency to attribution and move the industry toward new forms of measurement, we need to understand more about the sources of TV data, how accurate they are and what needs to be worked on,” said Jane Clarke, managing director and CEO, CIMM. “The industry will not be ready for true ad measurement until we have a better way to verify ad logs and can get fully accurate, representative samples.”

Howard Shimmel, president, Janus Strategy and Insights, added, “The importance of attribution to media companies, advertisers and their agencies grow each day. The industry is blessed by having so many high quality providers. Our hope is that this report provides a roadmap for providers to improve their offerings and at the same time reduce the dramatic differences between providers.”

The report provides three recommendations for TV attribution moving forward:

  • For the industry: Establish standards to ensure that data is organized comparably across providers. Ad-ID and the standardized commercial IDs it affords could definitely assist modelers to align the data, eliminate coding errors and reduce the time associated with data reconciliation.
  • For users: Before proceeding with an attribution study, make sure your occurrence data are validated. This might require using a specific validation study to ensure your data inputs are accurate. Otherwise, while directional guidance for tactical optimization may be trustworthy, ROAS or ROI estimates may be risky.
  • For providers: Test your QA procedures to ensure accuracy and be prepared to adopt industry standards as they are developed.
