Funnel Resonance Theory: An Impedance-Matching Framework for Advertising Conversion Optimization
SSRN · 6627779
The Takeaway
Advertising conversion is limited by a mismatch between different stages of the buyer's journey. This theory uses hard engineering math to align audience segments across those stages to create a state of resonance. When the funnel stages are perfectly matched, the efficiency of the entire system spikes nonlinearly. Marketers previously treated each stage of the funnel as a separate problem to be optimized. This discovery shows that the connection between the stages is where the real free growth is hidden.
From the abstract
<div> This paper introduces Funnel Resonance Theory, a cross-disciplinary framework demonstrating that effective advertising conversion capacity is bounded not by budget allocation, but by the intersection of audience segments addressed across sequential funnel stages. Drawing on impedance mismatch theory from electrical engineering, we define a reflection coefficient for each stage boundary, quantifying traffic structurally unable to convert. Under independent stage targeting, the conversion-el
