Judge each channel by the question it answers
A buyer clears a fixed sequence of doubts: do you exist, are you relevant, can I trust you, are you better than the alternatives, and after paying, was it worth it. Different channels settle different doubts, so the Reel that made the first impression and the review that built trust rarely get the last click. Measure each channel on the doubt it removes, not the sale it didn’t close.
