40 videos over 10 months on a product review channel in a boring hardware niche.
Revenue last month: $3,080
Affiliate links: $2,210
AdSense: $410
Sponsorships: $460 (one deal)
The interesting part is the distribution. Four videos make 71% of affiliate revenue. The other 36 videos are, financially speaking, a hobby. Every one of those four is a "X vs Y" comparison for a specific purchase decision.
If I started again I would make nothing but comparison videos and skip the entire first six months.
Ecom. Four stores, one that matters.
