CPA vs CPC vs CPM: How to Choose the Best Ad Network

Three pricing models define most of digital advertising today: CPA (Cost Per Action), CPC (Cost Per Click), and CPM (Cost Per Mille). The differences go far beyond the cost of a click, impression, or conversion. For many newcomers, figuring out which advertising model to choose – and which ad networks to consider – can be challenging. To make that decision easier, we’ve explained how each approach works, when it makes the most sense, and compared some of today’s most widely recognized CPA and CPC/CPM ad networks. For each platform, we’ve highlighted its main strengths, potential trade-offs, and the type of advertiser it’s best suited for.

CPA vs CPC vs CPM: What’s the Difference?

Choosing between CPA, CPC, and CPM isn’t just about how you pay for advertising. In practice, you’re also choosing between two different ways of acquiring traffic. 

With a CPA network, advertisers pay only when a predefined action is completed, for example, a registration, deposit, purchase, or app install. Affiliates promote campaigns, while the network provides offers, tracking, and payments. The advertiser focuses on the desired outcome instead of where the traffic comes from.

With a CPC or CPM ad network, brands buy traffic directly. They choose the targeting, upload creatives, set bids and budgets, and optimize campaigns themselves. The responsibility for conversions shifts from the affiliate to the advertiser.

Although CPC and CPM are different pricing models, they usually exist within the same type of advertising platform. The difference is simple:

— CPC (Cost Per Click) – charged per click on your ad.

— CPM (Cost Per Mille) – charged per 1,000 impressions.

The distinction between CPA and CPC/CPM goes beyond pricing models. In other words, this guide compares affiliate marketing and direct media buying – two fundamentally different approaches to performance advertising.

When Does Each Advertising Model Work Best?

Neither model is universally better. The right choice depends on your business goals, available resources, and the level of control you want over your campaigns.

Choose a CPA network if:

— You want to pay only for completed actions rather than clicks or impressions.

— You prefer working with affiliates instead of managing traffic sources yourself.

— You don’t have an in-house media buying team.

— Predictable acquisition costs are more important than full control over campaign optimization.

— You’re looking to scale through affiliate partnerships more than direct advertising.

Choose a CPC/CPM ad network if:

— You want full control over targeting, bidding, creatives, and budgets.

— You already have a media buying team or campaign management experience.

— You plan to test different audiences, GEOs, or ad creatives yourself.

— Building first-party audiences and optimizing campaigns over time is part of your strategy.

— You want to combine multiple traffic sources and scale directly.

Once you’ve decided which approach best fits your goals, the next step is to choose the right platform. 

Comparing Leading CPA and CPC/CPM Ad Networks

Affiliate marketing continues to grow rapidly. Industry estimates put the global affiliate marketing market at over $20 billion. As it expands, advertisers have access to an increasing number of networks and partnership models, demonstrating the need to compare tools beyond marketing claims.

Choosing a CPA network is about more than the number of offers available. They differ in the types of campaigns provided, payment conditions, campaign management, and the tools available to affiliates. Understanding these differences can help you find a platform that better matches your strategy.

Methodology: We selected CPA networks with an established reputation in performance marketing, active participation in the affiliate industry, regular product development, and broad recognition across professional communities. Unlike creating a ranked list, we chose companies that represent different approaches to CPA marketing.

ClickDealer

ClickDealer offers one of the largest CPA portfolios in the industry, with more than 16,000 offers across 40+ verticals and support for almost every major traffic source. It also provides the broadest range of payment models in this comparison, including Pay-per-call campaigns for selected advertisers. Advanced tracking features and flexible payment terms make the platform suitable for affiliates managing campaigns at scale. The main drawback is its relatively high minimum payout, which may be less convenient for smaller affiliates.

Best for: affiliates working across multiple verticals who need maximum flexibility in offers, traffic sources, and payment models.

Zeydoo

Zeydoo focuses on exclusive offers designed for social traffic, with SmartLinks, Playable Ads, and Meta-optimized campaigns at the core of the platform. Backed by the PropellerAds ecosystem, it combines proprietary technology with hands-on campaign management instead of leaving every decision to the affiliate. The network also proposes RevShare of up to 80% on selected offers, making it a profitable option for recurring revenue. The trade-off is a smaller portfolio compared to larger CPA marketplaces.

Best for: affiliates running Meta and social traffic who prefer a more managed approach than handling every aspect of campaign management themselves.

AdCombo

AdCombo keeps much of the campaign infrastructure in-house. One of its key strengths is full campaign localization, with landing pages and creatives available in more than 40 languages. The platform also supports the well-known Cash on Delivery (COD) model and provides its own tracking solution with API integrations for affiliates managing campaigns at scale. This approach gives advertisers and affiliates greater control over campaign quality while reducing dependence on third-party assets. The network also stands out with the lowest minimum payout among others, supports payments on request twice a week, and provides a wide range of withdrawal methods. Affiliates focused primarily on Tier-1 lead generation campaigns may find a smaller selection than on broader CPA networks.

Best for: affiliates running localized campaigns who value exclusive offers and fast payouts.

MaxBounty

MaxBounty is one of the longest-established CPA networks and focuses on direct performance offers rather than SmartLinks or marketplace-style solutions. With 2,000+ active offers, its portfolio is more selective, reflecting the platform’s emphasis on quality partnerships over sheer volume. The network also provides proprietary tracking tools, consistent weekly payouts for qualified affiliates, and a referral program, which makes it an attractive choice for affiliates who actively grow their professional community. The platform changes more conservatively than many competitors, prioritizing stability over frequent product experimentation.

Best for: affiliates looking for direct offers, reliable payouts, and sustainable growth.

Betsson Group Affiliates

Betsson Group Affiliates is the affiliate program of Betsson Group, giving partners direct access to more than 18 operator-owned brands across multiple regulated markets. The platform includes a comprehensive media gallery with localized banners, landing pages, HTML5 creatives, and personal tracking links, helping partners launch campaigns faster. Backed by a single operator, the program offers consistent branding and ready-to-use marketing assets. The limitation is a narrower portfolio, with campaigns focused exclusively on the gambling vertical.

Best for: publishers specializing in gambling traffic who prefer working with a single operator’s brands more than managing offers from multiple advertisers.

Best CPC/CPM Ad Networks

If CPA networks are built around offers, CPC and CPM ad networks are built around traffic. Instead of relying on affiliates to generate conversions, media buyers launch and optimize campaigns themselves. This gives them complete control over targeting, bidding, budgets, and campaign performance, but also makes the choice of ad platform more important.

To keep the comparison practical, we selected five well-known self-serve ad networks with a strong reputation in performance marketing. The selection is based on the same methodology as above: market presence, active product development, and visibility within the affiliate industry.

AdOperator

AdOperator delivers more than 3 billion ad impressions daily across 200+ GEOs, with a strong focus on traffic quality over simply maximizing volume. The platform combines automated fraud detection with manual traffic monitoring and supports cross-format retargeting across all available ad formats. Every advertiser works with a dedicated account manager, regardless of budget, and receives individual recommendations to improve campaign performance over time. At the moment, AdOperator offers popunder, push, and in-page push ad formats, focusing on long-term partnerships in such a competitive vertical as iGaming.

Best for: advertisers looking for high-quality traffic, transparent conditions, and a personalized approach to campaign optimization.

Kadam

Kadam has built its reputation on continuous product development, regularly introducing new tools and advertising technologies. One example is KAI, an AI assistant that helps users answer campaign-related questions and simplify routine tasks. The platform regularly expands its capabilities rather than relying on the same feature set year after year. The trade-off is a more technical interface that is better suited to advertisers with previous media buying experience.

Best for: experienced advertisers who like testing new tools, traffic sources, and optimization strategies.

Adsterra

Adsterra is one of the largest and most recognizable ad networks, reaching audiences across 248 GEOs. The platform offers the broadest selection of pricing models and has developed proprietary products such as Social Bar. It also maintains one of the industry’s largest educational blogs, making it easier for newcomers to learn different traffic acquisition strategies before launching campaigns. On the other hand, stricter campaign moderation, account verification, and a longer approval process (up to 3 hours during business days) can slow onboarding more than on some smaller competitors.

Best for: advertisers buying large volumes of global traffic.

EvaDav

EvaDav has been operating as an ad network since 2018. The platform prioritizes speed and simplicity, promising campaign moderation within 5 minutes and providing responsive support when advertisers need assistance. It also supports more than 40 payment methods, allowing you to top up account balance from any region. Compared to some larger competitors, EvaDav puts less emphasis on advanced automation and more on a straightforward advertising experience. 

Best for: advertisers who want to launch campaigns quickly and manage them without unnecessary complexity.

PropellerAds

PropellerAds has made campaign automation one of its core strengths. Features such as CPA Goal and Niko AI are designed to reduce manual optimization and help brands scale campaigns more efficiently. The company also maintains a strong presence in the affiliate industry through conference sponsorships, industry awards, strategic partnerships, and a steady stream of case studies and educational content. One drawback is that it currently offers fewer payment methods than most of its competitors.

Best for: advertisers managing multiple campaigns who want to automate optimization and scale efficiently.

How to Choose Between CPA and CPC/CPM Networks

As this ad network comparison demonstrates, CPA and CPC/CPM aren’t competing models – they complement each other. CPA networks are often used to expand affiliate reach and acquire conversions at a predictable cost, while CPC and CPM campaigns give advertisers direct control over traffic, testing, and optimization. Many experienced media buyers combine both approaches, using each where it delivers the greatest value.

If you’re looking for a CPC/CPM ad network that combines high-traffic quality, transparent pricing, dedicated account managers, and cross-format retargeting, explore what AdOperator can offer.

Frequently Asked Questions About CPA, CPC, and CPM models

How do CPA and CPC/CPM ad networks differ?

A CPA network connects advertisers with affiliates who promote offers for a commission on completed actions, such as registrations, purchases, or deposits. CPC/CPM ad network sells advertising inventory directly, allowing brands to purchase traffic from publishers through a self-serve platform.
