Understanding CPM, CPC, and CPA with Adsterra

To maximize your Adsterra earnings, you need to understand the pricing models that determine your revenue.

The Three Pricing Models

CPM (Cost Per Mille)

Definition: Earnings per 1,000 ad impressions

How it works:

• Advertiser pays for views, not clicks
• You earn every time an ad is displayed
• Rate varies by traffic quality

Example:

• CPM rate: $2.00
• Your impressions: 50,000
• Your earnings: $100

Earnings = (Impressions ÷ 1,000) × CPM Rate
         = (50,000 ÷ 1,000) × $2.00
         = $100

CPC (Cost Per Click)

Definition: Earnings per ad click

How it works:

• You earn when visitors click ads
• Higher risk, potentially higher reward
• Depends on CTR (Click-Through Rate)

Example:

• CPC rate: $0.50
• Clicks received: 200
• Your earnings: $100

Earnings = Clicks × CPC Rate
         = 200 × $0.50
         = $100

CPA (Cost Per Action)

Definition: Earnings when visitors complete an action

Actions include:

• Sign up for a service
• Make a purchase
• Download an app
• Fill out a form

Example:

• CPA rate: $5.00
• Conversions: 20
• Your earnings: $100

Which Model Pays Best?

**For property websites:** CPM is usually best because: - Consistent earnings regardless of clicks - Real estate visitors browse, don't always click - Predictable revenue

CPM Rates by Factor

Geographic Location

### Ad Format ### Device Type ## Calculating Your Potential Earnings

Monthly Revenue Estimate

Monthly Revenue = Daily Pageviews × 30 × (CPM ÷ 1,000)

Example for property site:

• Daily pageviews: 500
• CPM: $2.00

= 500 × 30 × ($2.00 ÷ 1,000)
= 15,000 × $0.002
= $30/month

Multiple Ad Placements

With 3 ad units averaging $1.50 CPM each:

= 500 × 30 × 3 × ($1.50 ÷ 1,000)
= $67.50/month
