Offerwall CPI vs CPA Offers Explained: What Publishers Earn Per Action
CPI vs CPA Offers: The Two Revenue Engines of Every Offerwall
Offerwall revenue comes from two action types: CPI (cost per install) and CPA (cost per action). Understanding both – and mixing them correctly – is how top publishers maximize earnings.
CPI Offers (Cost Per Install)
Users install an advertiser app and reach a defined depth (install + open, or install + level). Payouts range $0.30-$3.00 depending on geo and depth requirements. High supply – CPI offers fill most offerwalls.
CPA Offers (Cost Per Action)
Users complete non-install actions: sign-ups, purchases, surveys, subscriptions. Payouts range $0.50-$10+ for premium actions. Higher value per completion, lower volume than CPI.
How Conversions Validate
Every completion flows through the platform tracking engine: click recorded → action tracked → conversion validated server-side → signed postback fired → reward credited. Perkox validates with device fingerprinting and behavioral analysis to reject fraud.
Mixing for Maximum Revenue
- CPI installs for volume and consistent fill
- CPA actions for value spikes
- Surveys for engaged, patient users
- Rotate the mix by geo and audience segment
