If you own a product or an offer — casino, forex, crypto, nutra, dating, fintech, e-commerce — and you want to pay for results instead of clicks, this page explains how CPA-based traffic buying works, what you need to prepare, and how Mobadly structures cooperation: from brief and KPI definition to a capped test and scaling.
You submit the offer with vertical, GEOs, payout model and KPI definition.
Both sides confirm in writing what is billable, what is capped and what is prohibited.
A capped pilot on agreed sources with postback verification.
Sources and creatives are filtered by your approval data, not just conversion counts.
Volume grows only on cohorts that meet the agreed KPI.
CPA (cost per action) means you pay only when a user completes the action you defined as billable: a registration, a first deposit (FTD), a sale, a confirmed COD order, an approved lead. The traffic partner buys media at their own cost and carries the risk of impressions and clicks that do not convert — that is the fundamental difference from CPM or CPC buying, where you pay for delivery regardless of outcome. In exchange for carrying that risk, the partner needs a payout that makes the unit economics workable, clear conversion data, and the freedom to optimize sources. Variants of the model include CPL (per lead), FTD (per first deposit, common in iGaming and trading), sale or CPS (per purchase, common in e-commerce and nutra), COD (cash on delivery, paid on confirmed orders), revshare (a percentage of the revenue the user generates over time) and hybrid deals that combine a fixed action payment with a revenue share. Which of these models we work with for your vertical is confirmed during onboarding — terms are discussed individually.
In a CPA deal the risk is split explicitly. You carry the product risk: if the landing, the funnel, the payment page or the call center underperform, no traffic source can compensate for that. The traffic partner carries the media risk: the cost of clicks and impressions that do not convert. The shared risk is tracking: both sides lose when conversions are not recorded correctly, which is why postback testing before launch is not optional. A fair CPA relationship also shares information risk — you tell the partner which cohorts retain and pay, the partner tells you which placements and creatives produce those cohorts. Partners who buy blind optimize for cheap conversions; partners who see your quality data optimize for valuable ones.
Buying CPC or CPM yourself gives you full control and full risk: every test budget is yours to lose, and every source that fails is your cost. CPA outsourcing moves that cost of experimentation to the buyer's side — the media buying team absorbs failed tests because a failed source simply does not get paid. The trade-off is the margin: a CPA payout must be higher than the raw media cost per conversion, because it includes failed tests, fraud filtering and the team's work. For most offer owners the question is not which model is cheaper in theory, but which one converts budget into billable actions faster with the team you actually have.
Four things decide whether a CPA launch succeeds. First, a KPI definition: the exact event that is billable and how it is validated. Second, tracking: a postback URL that fires on that event, tested end to end — we work with common tracking platforms including Keitaro, Everflow, Affise, TUNE (HasOffers), CAKE, Binom, RedTrack and in-house setups. Third, caps and budget logic: how many conversions per day you can process and pay for. Fourth, creative rules: what partners may and may not say about your product, plus any licensing or GEO restrictions. Our offer brief template walks through the full checklist.
The process has five steps. Brief: you submit the offer with vertical, GEOs, payout model and KPI definition. KPI and caps agreement: both sides confirm in writing what is billable, what is capped, and what is prohibited. Test: a capped pilot on agreed sources with postback verification. Optimization: sources and creatives are filtered by your approval data, not just by conversion counts. Scale: volume grows only on cohorts that meet the agreed KPI. Reporting, postbacks and dispute handling follow the transparency rules described on the KPI and payout terms page.
We evaluate every offer individually: the vertical, the licensing situation, the target GEOs and the funnel itself. Some verticals and GEO combinations we cannot take — for legal, licensing or quality reasons — and we say so at the brief stage rather than after your budget is spent. For sensitive verticals (gambling, trading, supplements) you are responsible for holding the required licenses and complying with local advertising law; we will ask about licensing during onboarding and will not run traffic where it is prohibited.
Reports, postbacks and disputed conversions are handled against written KPI terms and logs on both sides. Payout models, schedules and hold periods are agreed individually per offer and confirmed in writing before traffic starts.
You pay a fixed amount for a defined action — registration, deposit, sale, confirmed order. Actions that do not happen are not paid for. The exact event, its validation and the payout are fixed in writing before any traffic starts.
CPA, CPL, FTD, sale (CPS), COD, revshare and hybrid combinations. Which model fits your offer depends on the vertical and your funnel economics — we discuss it during onboarding rather than quoting generic terms.
The media buying side. That is the core of the CPA model: you pay only for validated actions, and the cost of non-converting clicks and impressions stays with the buyer.
You define the billable event (for example, a first deposit of a minimum amount). It is tracked through a postback from your tracking platform, and conversions are reconciled against your approval data. Disputed conversions are reviewed against logs on both sides.
Common affiliate trackers such as Keitaro, Everflow, Affise, TUNE (HasOffers), CAKE, Binom and RedTrack, plus in-house postback setups. If you use something else, we check compatibility during onboarding.
Yes, and you should. Caps per day or per GEO protect your processing capacity and your budget. Scaling beyond the cap happens only after the pilot cohort passes your approval checks.
Yes, where the advertiser holds the required licenses and the GEOs allow such advertising. License status is part of the brief. We do not run offers where advertising is prohibited, and we do not help circumvent platform or legal restrictions.
Timing depends on how ready your tracking and creatives are. Once the postback fires correctly and KPI terms are agreed in writing, a capped pilot can be configured. Exact timelines are set per offer, not promised in advance.
