Conversion-based buying

Pay for conversions, not clicks

Two ways to buy results on Adexium. Auto CPA — target-based bidding that tunes CPM/CPC per traffic source to hit your cost-per-conversion goal, self-serve on every format. And CPA pricing — a fixed price per conversion on In-Page Push and Popunder, still in beta and granted on request.

Launch an Auto CPA campaign How Auto CPA works

How you get each one. CPA pricing is in beta and available on request rather than self-serve. It runs on direct-publisher In-Page Push and Popunder inventory only, so the volume behind it is a fraction of what CPM and CPC reach, and it works when the conversion you pay for sits early in your funnel — a registration or an install, not a deposit several steps later. Ask your account manager and we will tell you honestly whether your offer, geos and conversion event fit before you fund an account. Auto CPA bidding has no such limit: it is self-serve on every format and needs nothing but working conversion tracking.

Pricing models

CPM, CPC — and CPA in beta, on request

Pick the model that matches how much risk you want to carry. With CPA, the network carries it for you — which is exactly why we agree the conversion event with you before switching it on.

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 $0.30

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.

from $0.001

CPA

Pay per conversion

You define the conversion via postback and the price you pay for it. No conversion — no charge. In beta on In-Page Push and Popunder, granted on request.

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 — so we enable it per account, once we agree the event and the geos.

  • Beta, on request — In-Page Push and Popunder direct inventory
  • Fits an early funnel event — a registration or an install, not a deposit
  • 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.

  • Self-serve 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

Open any campaign, 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 — and one registered conversion.

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 couple of minutes. A campaign with no history starts in a learning phase on a capped exploration budget, priced against what the inventory actually clears at rather than a blind ceiling, and graduates to per-source optimization as its 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 Auto CPA unlocks for your account. Auto CPA needs S2S postback tracking and one registered conversion to unlock. Its first days are a learning phase on a capped exploration budget priced against the live market, after which bids follow measured performance per traffic source. CPA pricing takes one extra step — a word with your account manager. 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, and it is in beta, granted on request 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. Auto CPA is self-serve on every Adexium format.
Which formats support conversion-based buying?
Auto CPA bidding works on all six formats: Popunder, In-Page Push, Web Push, Telegram Mini Apps, Telegram Bots and iMe Messenger. CPA pricing exists on In-Page Push and Popunder only, and only on direct-publisher inventory, which is why it is still in beta and granted on request instead of self-serve.
What do I need to enable 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.
How do I get CPA pricing?
It is a beta, so ask your account manager or write to support before you fund an account. We look at the offer, the geos and — most of all — which event you want to pay for. CPA pricing works when that event is a registration or an install; a deposit sits several steps further inside your funnel, where the conversion depends on your landing page and payment flow rather than on our traffic, and campaigns priced that way have historically ended in refunds instead of volume. Auto CPA needs no approval: it aims at the same cost per conversion while billing stays CPM or CPC.

How does anti-fraud work?
Three layers, none of them a black box. Before the auction, the bidder rejects requests from iframes, datacenter ASNs, hammering IPs and malformed user-agents; proxy/VPN traffic is blocked on SSP supply and targetable by a flag on direct placements. On the click, a JavaScript challenge by Kaminari — an independent antifraud vendor — filters bots before the redirect. Daily, every placement is scored on outcomes: enough clicks with zero conversions for any advertiser, or the same email registering across accounts, and it is blocked network-wide. Confirmed fraud is refunded.
Can I whitelist or blacklist sources?
Yes — whitelist and blacklist by source ID, app ID and zone, per campaign. There is no optimizer that silently drops sources for you. If you want automation, Auto CPA re-bids per source toward your target cost per conversion and leaves the source list under your control.
Can I pay per conversion instead of CPM/CPC?
Yes, two ways. Auto CPA bidding is self-serve on every format: you set a target cost per conversion and the bidder tunes CPM/CPC bids per traffic source to hit it. CPA pricing, where you pay a fixed price per conversion and nothing otherwise, is in beta and available on request — it runs on direct-publisher In-Page Push and Popunder inventory only, so we agree the conversion event and geos with you first. Both require S2S postback conversion tracking.
