Setting Your Rate
How to setyour CPA.
Your CPA is adjustable, not locked in. Follow these principles to find your starting point, then optimize as data comes in.
- 01
Anchor to Your Business Value
Consider your Average Order Value (AOV), Lifetime Value (LTV), and margins to determine what a conversion is truly worth.
- 02
Establish a Realistic Baseline
Use your proven performance on Meta, Google, or affiliate channels as a starting point.
- 03
The Scale/Efficiency Scale
Low CPA means less volume. High CPA means more volume. Find the balance that matches your growth goals.
- 04
Align CPA with Your Product Cycle
An impulse buy requires a lower CPA. A high-consideration purchase requires more touchpoints and a higher CPA tolerance.
- 05
Set. Test. Scale.
Your CPA is adjustable, not locked in. Set a baseline to gather data, then raise it to unlock scale or lower it to sharpen efficiency.

CPA buying, answered
Traditional podcast advertising is CPM-based, show-based, and often host-read, which means advertisers pay upfront for impressions and hope the campaign performs. Audiohook removes that upfront media risk, operating on a true CPA model. We fund and run the media ourselves, optimize the campaign in real time, and bill only on conversions we can confidently attribute to audio.
Audiohook requires a 30-day minimum commitment and a minimum monthly spend cap of $10,000 for Audiohook-managed campaigns. That cap is not a guaranteed spend. It is the minimum runway the system needs to optimize effectively. If Audiohook only drives $5,000 worth of validated conversions in a month, only $5,000 is billed.
Yes. Campaigns run on a flat-rate CPA, not a target CPA and not a percentage-based rev share. The brand chooses the fixed dollar amount it is willing to pay per conversion, and that amount can be adjusted during the campaign as performance data comes in.
The best starting point is usually where Meta and Google CPAs are backing out, combined with what makes sense based on the brand's AOV, LTV, and margin structure.
Audiohook works across most advertiser verticals (D2C, B2B, subscription brands), but the best-fit brands have a trackable conversion event, enough baseline volume to support optimization (typically 3,000 to 5,000 monthly conversions and at least 100,000 page views), and a clear definition of success they can act on, including creative iteration, CPA adjustments, and geo strategy.
