Pay for conversions, not clicks

Two ways to buy results on Adexium: CPA pricing — you set the price of a conversion and pay only when it happens — and Auto CPA — target-based bidding that tunes CPM/CPC per traffic source to hit your goal.

Pricing models

CPM, CPC — and now CPA

Pick the model that matches how much risk you want to carry. With CPA, the network carries it for you.

CPM

Pay per 1,000 impressions

Classic reach buying. Best for prospecting at scale and formats where the view itself does the work — popunder, Mini App placements.

from $0.65

CPC

Pay per click

You pay only when a user clicks. Best when your landing page converts predictably and you want tight control over funnel cost.

CPA

Pay per conversion

You define the conversion via postback and the price you pay for it. No conversion — no charge. Available for In-Page Push and Popunder.

you set it
Two levels

Fixed CPA price or an automated goal

Both options optimize for the same thing — your cost per conversion. They differ in who does the work.

CPA pricing

A billing model. You name the price of a conversion; Adexium delivers traffic and you are charged only for postback-confirmed conversions. The volume risk is on the network, not on your budget.

  • Available on In-Page Push and Popunder
  • Self-serve — pick CPA next to CPM/CPC when creating a campaign
  • Conversion defined by your S2S postback

Auto CPA bidding

A bidding strategy. Billing stays CPM/CPC, but instead of a fixed bid you set a target cost per conversion — and the bidder chases it per traffic source, like target-CPA bidding in Google Ads, on pop, push and Telegram inventory.

  • Works on all six formats, Web and Telegram
  • Per-source optimization with automatic cutoff of overpriced sources
  • Toggle Fixed bid ↔ Auto CPA per campaign, any time
Under the hood

How Auto CPA hits your target

No black box: here is what the bidder actually does with your goal.

1 · Set your target

In the campaign form, switch the bid strategy from Fixed bid to Auto CPA and enter your target cost per conversion. Requires conversion tracking — a 5-minute postback setup.

2 · Per-source bidding

For every traffic source, the bidder derives the bid from your target and that source’s real conversion rate. Sources that convert get bid up; weak ones get bid down automatically.

3 · Automatic cutoffs

A source whose realized CPA runs above 3× your target is dropped from the auction entirely — not just bid lower. Your budget stops flowing to traffic that misses the goal.

4 · Continuous learning

Conversion stats refresh every few minutes. New sources start on a conservative baseline and graduate to per-source optimization as their own conversions accumulate.

What you need to start

One thing: conversion tracking. Wire an S2S postback in the dashboard (about 5 minutes), fire a test conversion, and both CPA pricing and Auto CPA unlock for your account. Minimum deposit is $100 — same as any Adexium campaign, across 225+ geos.

FAQ

CPA & Auto CPA questions

What is the difference between CPA pricing and Auto CPA?
CPA pricing is a billing model: you pay a fixed price per tracked conversion, available on In-Page Push and Popunder. Auto CPA is a bidding strategy: billing stays CPM/CPC, but the bidder automatically tunes bids per traffic source to hit your target cost per conversion — available on all Adexium formats.
Which formats support conversion-based buying?
CPA pricing is available for In-Page Push and Popunder campaigns. Auto CPA bidding works on all six formats: Popunder, In-Page Push, Web Push, Telegram Mini Apps, Telegram Bots and iMe Messenger.
What do I need to enable CPA or Auto CPA?
Conversion tracking via S2S postback. The Auto CPA option unlocks automatically once your account has registered a test conversion or a real one. Setup takes about 5 minutes in the Tracking section of the dashboard.
How does Auto CPA protect me from bad traffic?
Three mechanisms: bids are computed per source from its real conversion rate, sources whose realized CPA exceeds 3× your target are cut from the auction automatically, and a hard bid cap prevents runaway prices while the algorithm is still learning a new source.
Can I switch between Fixed bid and Auto CPA?
Yes. The bid strategy is a per-campaign toggle — you can switch an existing campaign to Auto CPA or back to a fixed CPM/CPC bid at any time.

Kaminari, our independent antifraud partner, adds verification cross-checking every impression and click against industry-wide fraud signals. Bot, incentivized, and invalid traffic is filtered automatically; confirmed fraud is refunded.
Can I whitelist or blacklist sources?
Yes — full whitelist/blacklist control by source ID, app ID, and zone. AI Source Optimizer can also auto-manage sources based on your KPI targets.
Can I pay per conversion instead of CPM/CPC?
Yes, two ways. CPA pricing: on In-Page Push and Popunder you set the price per conversion and pay only when it happens. Auto CPA bidding: on any format you set a target cost per conversion and the bidder auto-tunes CPM/CPC bids per traffic source to hit it. Both require S2S postback conversion tracking.
