The ROI of Political Advertising-Multi Touch Attribution in Cross-Channel Campaigns

Political campaigns have evolved significantly with the advent of digital media, shifting from traditional broadcasting to a multifaceted approach where every interaction with potential voters can be tracked and analyzed.

This shift has brought to the forefront the importance of understanding the Return on Investment (ROI) for political advertising through Multi-Touch Attribution (MTA) models in cross-channel campaigns.


Conceptual Framework

  • ROI in Political Campaigns: ROI measures the effectiveness of an investment. In political campaigns, this translates to understanding how advertising spend translates into voter engagement, persuasion, and ultimately, votes.

  • Multi-Touch Attribution (MTA): MTA involves identifying a set of user actions (touchpoints) that contribute to a voter's decision-making process and assigning value to each of these actions. This model contrasts with single-touch models, which might attribute all credit to the first or last interaction.

  • Cross-Channel Campaigns: These campaigns utilize multiple platforms (TV, radio, social media, email, etc.) to reach voters. The challenge lies in attributing the correct impact to each channel.


Theoretical Foundations

The theory of attribution in marketing, which has psychological roots, helps in understanding how voters process information and make decisions.

In politics, this translates into how various campaign touchpoints contribute to a voter's final choice.

Practical Application: A Scenario with Data

Imagine a hypothetical campaign for Candidate X in a U.S. Senate race:


  1. Channels Utilized:

    • Social Media (Twitter, Facebook)

    • Email Campaigns

    • TV Ads

    • Public Rallies (Physical touchpoints)

    • Google Ads

  2. Touchpoints Tracking:

    • First Touch: A voter sees a Google Ad introducing Candidate X.

    • Intermediate Touches: Follows on Twitter, receives weekly emails, sees TV ads.

    • Conversion Touch: Attends a rally and decides to vote for Candidate X.

  3. Data Collection:

    • Google Analytics for digital footprints.

    • CRM system for email interactions.

    • Voter registration and turnout data linked with survey responses about campaign touchpoints.

  4. Attribution Model Applied:

    • Position-Based Model: 40% to first and last touch, 20% distributed among others. Here, Google Ads and the rally get significant credit, but social media interactions and emails also contribute.

  5. ROI Calculation:

    • Cost: Total spend across all channels.

    • Outcome: Increase in voter turnout attributed to campaign activities, measured by comparing turnout in areas with heavy vs. light campaign presence.


    If the campaign cost $2 million and resulted in an estimated additional 10,000 votes, with each vote costing $200 in advertising, but contributing to a win with a margin of 5,000 votes, the strategic importance of those votes could be worth much more in political capital.


Scholarly Perspectives

  • Rex Briggs: His work on measuring the ROI of marketing efforts, particularly in comparing online vs. traditional media, can be adapted to political advertising. Briggs' insights suggest that around 37% of advertising might be ineffective, prompting a need for better attribution models in politics to minimize waste.

  • Forbes' Insights on Marketing Measurement: The comparison between A/B testing, Market-Mix Models (MMM), and MTA in marketing can be translated into political campaigns where A/B testing could be voter reactions to different campaign messages, MMM for overall campaign impact analysis, and MTA for detailed voter journey mapping.


Challenges and Considerations

  • Complexity and Cost: Implementing a robust MTA system requires significant investment in technology and expertise.

  • Data Integration: Combining data from online and offline sources to get a unified view of voter interactions.

  • Dynamic Voter Behavior: Political climates change rapidly, affecting the weightage of touchpoints over time.

Understanding the ROI through MTA in political advertising requires a nuanced approach where every voter interaction is potentially a data point contributing to the larger picture of campaign effectiveness.

As digital platforms evolve and voter behavior shifts, the political campaigns that adapt and refine their attribution models will likely gain a strategic advantage in optimizing their advertising spend for maximum voter impact.

This necessitates ongoing scholarly work and practical experiments within campaigns to refine these models for political success.
