How do you measure podcast advertising?
The attribution problem stated plainly: someone hears your spot in a car and buys from their laptop that evening. Nothing connects those two events by default. Everything on this stage is a method for building that connection, and each has a cost, a floor, and a blind spot. The CFO-defense framing matters because the person who approved the test will judge the readout.
Promo codes and vanity URLs
The workhorse: per-show attribution the platform cannot grade for itself. Fits every budget.
From ~$10kPixel attribution
IP and device matching between listen and visit. Real signal, real limits, honest at scale.
Every budgetCAC and payback modeling
The arithmetic that turns redemptions into a finance-grade readout.
Matching method to budget
Under $2,500: codes plus a checkout survey question, nothing else; pixel vendors’ matching needs more volume than your flight delivers. $2,500-15,000: codes per show, survey question mandatory, pixel optional on the platforms that include one free (Spotify). Above $15,000: add dedicated pixel attribution and reconcile it against codes; where the two disagree, the truth is usually between them.
Set up before launch, always
The pre-launch checklist: codes created and tested at checkout, vanity URLs live and redirecting, survey question deployed, pixel firing verified, baseline traffic recorded so you can spot the lift window. Retrofitted measurement produces a number, but not one you should present. The readout format a finance team accepts is on CAC and payback.
