Why it works
The buyer names the channel. No cookie, no click path. It covers the places pixels miss: AI assistants, friends, podcasts. The "Other" box shows channels you did not think to list.
When to start

How to read it
Each answer sits next to the revenue of its order, so you see revenue by channel, not only votes. Put it next to what you spend on each channel. A channel that brings in more than it costs may deserve a bigger test budget. Treat it as a signal to test, not a final verdict.
