Key Takeaways

  • CPA means advertisers only pay when someone completes a specific action (purchase, sign-up, download)

  • CPA puts more risk on publishers but can deliver higher payouts ($1-$100+ per conversion)

  • CPA works best for publishers with conversion-optimized content and strong audience trust

  • Unlike CPM (paid per 1,000 views) or CPC (paid per click), CPA requires completed actions beyond the initial impression or click

What is Cost Per Action, Anyway?

If you're just getting started with monetization, you've probably heard terms like CPM, CPC, and CPA thrown around. Today, we're tackling CPA – Cost Per Action (sometimes called Cost Per Acquisition).

In simple terms, CPA is a pricing model where advertisers only pay when a visitor performs a specific action. That action could be:

  • Making a purchase

  • Signing up for a newsletter

  • Completing a form

  • Installing an app

  • Creating an account

The beauty of CPA for advertisers is pretty obvius – they only pay when they get exactly what they want. And for publishers with the right audience and content, CPA can offer much higher payouts than traditional impression-based models.

How CPA Compares to Other Pricing Models

Looking at our ad pricing models, we can see they exist on a spectrum of risk:

Model

Payment Trigger

Publisher Risk

Advertiser Risk

Typical Rates

CPM

Ad impression (view)

LOW

HIGH

$0.50-$5 per 1,000 impressions

CPC

Ad click

MEDIUM

MEDIUM

$0.10-$2 per click

CPA

Completed action

HIGH

LOW

$1-$100+ per action

With CPM, publishers get paid just for showing ads, regardless of performance. At the other end, CPA requires the full conversion funnel to work perfectly before a publisher sees a penny.

Who Should Use CPA Monetization?

CPA works great for:

  1. Publishers with conversion-focused content – If your content naturally leads to purchasing decisions or specific actions, CPA can be lucrative.

  2. Sites with strong audience trust – When visitors trust your recommendations, they're more likely to complete the desired actions.

  3. Niche sites with engaged visitors – Highly targeted content often converts better than general interest sites.

However, CPA isn't right for everyone. News sites, for example, typically struggle with CPA because news consumption doesn't naturally lead to purchasing behavior.

CPA Rates: What Can You Expect?

CPA rates vary WIDELY depending on:

  • Industry (finance pays more than gaming)

  • Action complexity (purchases pay more than email signups)

  • Traffic quality (targeted audiences are worth more)

According to BusinessOfApps, 2024 CPA rates range from around $20 for simple actions in the gaming industry to over $50 for finance-related conversions.

For subscription-based actions, expect between $40-$60 per conversion in 2024.

CPA Networks vs. Direct Deals

You can access CPA offers through:

  1. CPA Networks – Platforms like MaxBounty or Impact aggregate offers from multiple advertisers.

  2. Affiliate Programs – Many companies run their own programs, often paying higher rates than through networks.

  3. Direct Deals – Once you prove your value, negotiating directly with advertisers can yield the best terms.

New publishers typically start with networks to gain access to multiple offers, then graduate to direct relationships as they demonstrate success.

The Pros and Cons for Publishers

Pros:

  • Higher payouts per conversion

  • Better alignment with advertiser goals

  • More predictable ROI for advertisers (which can lead to ongoing partnerships)

Cons:

  • No guaranteed income (unlike CPM)

  • Publisher bears conversion risk

  • Requires more sophisticated tracking

  • Might tempt publishers to create overly promotional content

Getting Started with CPA

If you're considering CPA monetization:

  1. Analyze your current traffic – Do visitors already take actions that could be monetized?

  2. Start small – Test a few relevant offers before overhauling your strategy

  3. Track everything – Understand which placements and content drive conversions

  4. Optimize for conversion – Experiment with call-to-actions, placement, and messaging

Remember that CPA works best alongside other models. Most successful publishers use a mix of CPM, CPC, and CPA to maximize revenue.

The Future of CPA

The CPA model continues to evolve, with some interesting trends for 2024:

  • More sophisticated attribution models that account for multiple touchpoints

  • Growing emphasis on mobile app installs and engagement

  • Integration with influencer marketing campaigns

  • Greater focus on quality over quantity of conversions

As tracking becomes more complex due to privacy regulations, expect to see new variations of the CPA model emerge that balance publisher risk with advertiser demands.

Wrap-Up

Cost Per Action isn't for every publisher, but when your content naturally leads to conversions, it can be significantly more lucrative than impression-based models.

The key is understanding where your audience is in their journey. If they're in research mode, CPM might make more sense. If they're ready to take action, CPA could be your ticket to higher monetization.
