A funnel's buyer-to-customer conversion rate reads better than expected, and the business can't quite explain which part of the asset or follow-up sequence is producing the extra conversions.
A referral is someone who was likely to become a customer through the referral relationship alone. If that same person also happens to have bought your book or asset at some point, a funnel built to credit whatever touchpoint it last saw will attribute the resulting business to the asset, inflating its apparent conversion rate. The funnel didn't produce that customer. The referral did. This is quieter than a tracking bug, because nothing is technically broken; the attribution model is simply answering a question it was never built to separate.
Ask one question, recorded verbatim, on every first call: how did you come to be talking to me. The gap between that answer and what your tracking system reports is your laundering rate, and it's usually larger than whoever runs the funnel expects. Count referral-sourced and funnel-sourced customers separately on close rate, cycle length and value; pooling the two hides the truth about both.
Pull your last twenty new customers and check, from the actual first-call answer rather than the tracking system, how each one really found you. If a meaningful share were referrals who also happened to be in your funnel, your tracked buyer-to-customer rate is overstated by exactly that share.
