- Marketers trying to figure out which channel is actually responsible for growth, not just which one gets credit.
Last-click attribution tends to credit whichever channel someone happened to click right before signing up, which is often a search ad for the brand name itself, or a channel that captured demand actually created somewhere else — a podcast mention, word of mouth, an earlier touchpoint the data doesn't capture cleanly. This prompt looks past the attribution model's convenient story to find what's plausibly the real driver.
When not to use this
If you have genuinely clean, single-channel attribution (a unique landing page per channel with no other marketing running), the attribution data is probably trustworthy as-is — this is for the common, messier case.
Did this work?
You have a specific, honest read on which channel is likely driving real growth versus which one is just capturing credit for demand created elsewhere.
