Step-by-Step Examples
Example 1
Mid-Roll Buy
42,000 downloads, 1,050 per episode, mid-roll, 8 episodes, 0.4% conversion, 68 AOV.
- CPM = (1,050 / 42,000) × 1,000 = 25.00
- Within the typical 25–35 mid-roll range
- Campaign = 8,400 cost, 336,000 gross impressions
- Orders ≈ 1,344, cost per order 6.25
- Revenue 91,392, ROAS 10.88:1
✓ 25.00 CPM — within typical range
Example 2
Overpriced Pre-Roll
20,000 downloads, 900 per episode, pre-roll.
- CPM = 45.00
- Well above the typical 15–25 pre-roll range
- Worth negotiating or verifying the download figure
✓ 45.00 CPM — above typical range
Example 3
Good Value
80,000 downloads, 1,400 per episode, mid-roll.
- CPM = 17.50
- Below the typical mid-roll range
- Strong value if the audience fits
✓ 17.50 CPM — good value
Real-World Applications
Placement Pricing
Mid-roll commands the highest rates because listeners are already engaged and less likely to skip.
CPM Comparison
Expressing podcast rates as CPM allows comparison against other audio and digital channels.
Attribution Codes
Promo codes and vanity URLs are the practical attribution mechanism, though they systematically undercount.
Host-Read Premium
Host-read ads typically outperform produced spots, which is part of why podcast CPMs exceed most display inventory.
Common Mistakes to Avoid
⚠️
Trusting download numbers uncritically
Download counts vary by measurement standard and can include partial or automated downloads. Ask which standard is used.
⚠️
Expecting precise attribution
Podcast listeners frequently convert later through direct navigation or search. Promo code attribution typically captures only a fraction of actual response.
⚠️
Buying a single episode
Podcast advertising generally needs repetition to work. Single-episode tests usually underperform and lead to premature conclusions.
Frequently Asked Questions
What is a typical podcast CPM? ▾
Roughly 15 to 25 for pre-roll, 25 to 35 for mid-roll, and 10 to 15 for post-roll, though popular shows and niche audiences command more.
Why is mid-roll more expensive? ▾
Listeners who have stayed past the opening are more engaged and less likely to skip, making mid-roll placement more effective.
How do I track podcast conversions? ▾
Unique promo codes and vanity URLs are standard, though both undercount since many listeners convert later through other paths.
How many episodes should I buy? ▾
Podcast advertising typically requires repetition. Multi-episode flights on the same show usually outperform scattered single placements.
Are host-read ads better than produced spots? ▾
Generally yes. Host-read ads carry the host's credibility with their audience, which is a substantial part of the channel's effectiveness.
