Use this to explain why two sites with similar traffic can earn very different revenue.
RPM shifts because advertiser demand, audience quality, and page-level monetization execution all move at the same time.
Guide
Tier 1 audiences and high-intent niches usually monetize at meaningfully higher RPMs than broad entertainment traffic.
Traffic source intent also matters. Search-led traffic often monetizes differently from social spikes, even with similar session volume.
Guide
RPM is heavily shaped by ad placement, session depth, layout, and viewability.
A better ad stack can raise RPM without increasing pageviews.
Small UX decisions like content width, sticky elements, and placement spacing can materially affect viewability and user retention at the same time.
Guide
Publisher RPM often lifts in stronger advertiser periods and softens in weaker buying windows, even when traffic is flat.
If you do not account for seasonality, you may incorrectly attribute normal market swings to product changes.
Guide
Start with one question: is the RPM change mostly traffic-driven, inventory-driven, or demand-driven?
Then run the same month through your utility calculators and compare assumptions step by step until one lever explains most of the gap.
