Two creators. Both have 100,000 subscribers and 500,000 views per month. One earns $1,200/month from AdSense. The other earns $12,000. The difference: niche.
RPM (Revenue Per Mille — your earnings per 1,000 views) varies by 10-15x depending on the category of content you make. Choosing a niche without understanding RPM is choosing your income ceiling before you start.

Why RPM Varies So Dramatically
Advertiser intent alignment: A viewer watching "best index funds for retirement" is one click away from a financial product purchase. Advertisers pay $30-50 CPM for that placement. A viewer watching gaming content is likely not about to buy a $500 software tool.
Audience demographics: Advertisers pay more to reach affluent, older audiences. Personal finance content tends to attract 30-55 year olds with disposable income. Gaming skews younger.
Competition between advertisers: When 50 financial services companies all want to advertise on personal finance channels, CPMs go up. When only 3 gaming gear brands compete for gaming content, CPMs stay low.
The RPM vs. Views Trade-off
High-RPM niches have lower total potential audience size:
| Niche | Est. global addressable audience | Typical RPM |
|---|---|---|
| Personal finance | 100-200M | $25 |
| Gaming | 1.5-2B | $4 |
| Entertainment | 3B+ | $2 |
A gaming channel targeting 1B viewers at $4 RPM can earn more in absolute dollars than a personal finance channel at $25 RPM — but requires dramatically more views. The math:
- Personal finance at 1M views/month: $25,000 AdSense
- Gaming at 1M views/month: $4,000 AdSense
Both require years of work. The question is where you're pointing that work.
The Right Niche Selection Framework
RPM alone shouldn't determine your niche. The formula:
Niche score = (RPM × likely achievable views) × (creator sustainability)
A high-RPM niche you'll quit in 6 months is worth zero. A lower-RPM niche you'll create in for 5 years compounds into significant income through sponsorships, products, and audience depth.
Sponsorship multiplier: High-RPM niches also attract better sponsorships. A personal finance channel with 50K subscribers can command $3,000-8,000 per sponsored video. A gaming channel with 50K subscribers commands $300-800.
The RPM gap of 6x becomes a sponsorship gap of 10x.
