The inevitable decline in conversion efficiency that occurs when a marketing channel's audience becomes habituated to your specific messaging style, rendering previously high-performing tactics invisible.
Channel resonance decay is the silent tax on every successful campaign. When you find a winning hook or creative format, you naturally double down. Eventually, the audience stops seeing the message as a signal and starts seeing it as background noise.

The real solution is to rotate the creative architecture or shift the narrative frame entirely to re-engage the audience's attention. If you are not actively planning for the decay of your current winning assets, you are already behind the curve.
