Ads pay per impression, not per reader. Page views × ads per page × fill rate × RPM — the full display-ad revenue chain, without the marketing fluff.
Every field from page views to RPM is a real lever — none of them can be zero.
Lifestyle blogs might see $5–15 RPM; finance and B2B often reach $20–50.
Not every slot gets sold. 85% fill is healthy; below 70% you're leaving money on the table.
