Reachoz MediaEvery campaign on a performance network pays for one of three things: a sale, a lead, or an install. Which one an advertiser picks changes what a publisher should expect to earn, how fast it pays, and how much review sits between a click and a payout. Here's what each model actually rewards, and where it fits.
CPS — cost per sale
The advertiser pays a percentage of the order value, or a fixed amount, once a purchase is placed and doesn't get refunded or cancelled. This is the default model for most coupon and cashback campaigns, because it maps directly to what the advertiser wanted in the first place — a sale.
CPS rewards traffic that converts, not traffic that clicks. A coupon page ranking for "[brand] discount code" with a strong conversion rate can out-earn a much larger site on flat-rate traffic, because every redemption is worth something instead of a fraction of a fixed click rate.
CPS pays for the outcome the advertiser actually wanted. Everything else is a proxy for it.
The tradeoff: earnings depend on the advertiser's checkout converting, order sizes, and refund rates — none of which the publisher controls directly. A campaign with a high payout rate but a weak checkout can still underperform one with a lower rate and a smoother funnel.
CPL — cost per lead
The advertiser pays when someone completes a defined action short of a purchase — a sign-up, a form fill, a free trial start, or an account opened. Financial services, subscription products, and app-adjacent offers lean on CPL because the "sale" often happens later, off the network's visibility.
CPL usually pays faster to confirm than CPS, since there's no refund window to wait out. It also usually comes with tighter qualification rules — a lead has to be real (verified email or phone, sometimes a KYC step) for it to count, which is why CPL campaigns often reject a higher share of raw submissions than CPS campaigns reject sales.
CPI — cost per install
The advertiser pays once their app is installed, and sometimes a second time when a specific in-app action happens after that (a first order, a level completed, an account funded). CPI is the standard model for app-driven advertisers — food delivery, fintech, and gaming most commonly.
Attribution for CPI relies on the mobile ecosystem's own tracking (device or SDK-based), which behaves differently from a browser cookie. That's a separate topic — the short version is: CPI campaigns need the advertiser's mobile measurement partner connected correctly, or installs go untracked regardless of how good the publisher's traffic is.
Picking a model, as an advertiser
| If your goal is | Use | Because |
|---|---|---|
| A direct sale | CPS | You only pay when revenue actually lands. |
| Sign-ups or applications | CPL | You can qualify and pay before a purchase happens. |
| App growth | CPI | Install is the action you can measure fastest and most reliably. |
Picking a campaign, as a publisher
The listed payout rate isn't the number that matters — the effective EPC (earnings per click) is. A 10% CPS offer on a page with a 2% conversion rate can earn less than a 5% CPS offer on a page with a 6% conversion rate. Before committing a placement, ask for (or check, if the network shows it) the campaign's actual historical conversion rate and average order value, not just the headline percentage.
The takeaway
CPS, CPL, and CPI aren't competing options — they fit different kinds of offers. What matters more than which model a campaign uses is whether its terms are stated clearly up front: what counts as a valid conversion, how long the attribution window is, and how fast approved earnings actually get paid.
