Podcast listeners hear your ad while driving, cooking or running. They don't click. Days later they search your brand, or buy on Amazon, and the podcast gets no credit. That's why podcasts are some of the most under-measured channels in marketing.
Signals you can capture from podcasts
- Promo codes. A unique code per show is the strongest signal. A redemption ties a sale to a show exactly.
- Vanity URLs. A short URL like
brand.com/showlets the tracking snippet record a visit with a campaign tag. - "How did you hear about us?" Survey answers at checkout add coverage when codes aren't used.
- Timing and network. Listening often happens at home, and a later purchase from the same household network inside your lookback window is a meaningful, if probabilistic, signal.
Sending podcast touchpoints
Because there is no click, podcast touchpoints are sent server-side. Each one needs a time and at least one key (an email, IP address or click ID):
curl -X POST https://YOUR-APP/api/touchpoints \
-H "Authorization: Bearer ot_live_…" -H "Content-Type: application/json" \
-d '[{"channel":"podcast","campaign":"founder-interview","occurred_at":"2026-10-20T14:03:00Z","email":"pat@example.com"}]'See podcasts, email, TV and affiliates in the help center.
Use vanity URLs with UTMs
Point each show's vanity URL at a landing page with UTM tags, like utm_source=podcast&utm_campaign=show-name. The snippet records the visit, and any later order matched to that visit credits the show. Our UTM guide covers naming.
Judge podcasts with first touch
Podcasts usually start journeys rather than finish them. Under last-touch attribution they look weak, because the final touch is often a branded search. Check first-touch and linear views before cutting a show. See attribution models compared.
Podcasts that sell on Amazon and in store
Many podcast-driven purchases happen off your site. When you bring Amazon orders and in-store sales into the same place, a podcast can get credit for an Amazon order or a register sale, with match confidence shown. Read about in-store attribution.
Common mistakes to avoid
- One code for every show. Without a unique code or URL per show, you can't compare them.
- Cutting shows on last-touch data. Podcasts start journeys; judge them on first touch and linear.
- Forgetting host-read timing. Episodes keep getting downloads for weeks, so use a 30-day or longer window.
Frequently asked questions
Are promo codes enough to measure podcast ads?
They capture listeners who remember and use the code, which is usually a minority. Combine codes with vanity URLs, survey answers and network matching for a fuller picture.
How long after an episode do sales show up?
Often for weeks, because episodes keep getting listens after release. A 30- or 90-day lookback window fits podcasts better than 7 days.
Can podcast ads be matched to Amazon sales?
Yes. Bring Amazon orders in and they're matched to podcast touchpoints by network and timing, with a confidence score. See Amazon attribution.
