One channel, two niches: a 9x CPM swing

One channel, two niches: a 9x CPM swing

A frequently-cited self-reported case in creator forums involves a single YouTube operator who ran two channels with near-identical production budgets and upload cadence (3 videos/week) for 12 months.

Context:
— Channel A: general gaming commentary, ~480K views/month
— Channel B: personal-finance explainers, ~210K views/month

Findings:
— Gaming RPM settled around $1.80
— Finance RPM averaged $16.40 — roughly 9x
— Despite less than half the views, Channel B out-earned A on ad revenue ($3,440 vs $864/month)

Caveats: this is a single self-reported pair, not a controlled study. Advertiser demand for finance keywords is seasonal and US-skewed; the operator's finance audience was 71% US versus 38% for gaming, which alone explains much of the gap. RPM is also reported post-revenue-share, and we cannot verify the figures.

Implications: the case is consistent with the broader pattern that niche, not view count, dominates ad earnings — but a single pair cannot isolate niche from geography or seasonality.

What we still don't know: how much of the 9x is durable versus a function of that specific year's advertiser auction.
