How to use the AdsTerra Income
- Enter monthly pageviews and ads shown per page.
- Enter your average CPM in your currency.
- Set the fill rate, which is rarely 100%.
- Adjust CPM by traffic geography before trusting the total.
How the calculation works
Revenue = impressions ÷ 1,000 × CPM × fill rate, where impressions are pageviews multiplied by ad units per page. Fill rate is the share of ad requests actually filled with a paying ad; it varies with format and geography and is often 85–95% rather than complete.
Geography dominates CPM more than any other variable. Tier-1 traffic from the US, UK, Canada and Australia typically earns several times what tier-3 traffic earns for identical placements, so a blended CPM computed across mixed traffic hides wide variation. Format matters next: popunders and interstitials pay far more than display banners but cost user experience and can breach search-quality expectations. Ad blockers remove 15–30% of desktop impressions before they are ever counted.
Revenue = (pageviews × ads per page / 1000) × CPM × fill rateSource: Standard CPM revenue accounting for display and popunder ad networks.
Worked example
320,000 monthly pageviews, 2 ad units per page, 1.85 CPM, 90% fill rate.
- Impressions = 320,000 × 2 = 640,000.
- Thousands of impressions = 640.
- Gross = 640 × 1.85 = 1,184.
- After 90% fill = 1,065.60.
About 1,066 a month — heavily dependent on the traffic mix behind that CPM.
Frequently asked questions
What CPM should I expect?+
It depends almost entirely on geography and format. Tier-1 traffic can earn several times tier-3 for the same placement.
Why is my fill rate below 100%?+
Not every request finds a paying advertiser, particularly in low-demand geographies or at unusual hours.
Do ad blockers reduce earnings?+
Yes, by roughly 15–30% of desktop impressions depending on audience.
Are popunders worth it?+
They pay more per impression but hurt user experience and retention. Weigh long-term traffic against short-term revenue.
