Stop A/B testing thumbnails like a coward. Here's the protocol that finds winners.

Stop A/B testing thumbnails like a coward. Here's the protocol that finds winners.
Swapping thumbnails on a whim teaches you nothing. Run it like a lab:
— Change ONE variable per test: face vs no-face, OR text vs no-text. Never both
— Give each version 48 hours minimum and 5,000+ impressions before you judge
— Track click-through on the IMPRESSION graph, not vibes
— Kill anything under your channel baseline, keep the winner for 2 weeks before retesting
For affiliate videos, the thumbnail decides 80% of your revenue before a word is spoken. Test it like it matters. Who's still guessing?
