AdSense Experiments vs eyeballing it

AdSense Experiments vs eyeballing it
Stop A/B-ing placements in your head. Use the Experiments tab — it splits traffic 50/50 and tells you the winner with actual confidence.
Gut-feel testing fails because you change a placement, traffic shifts that week (seasonal, a viral post), and you credit the wrong thing.
Experiments holds everything constant. I let one run 14 days minimum — anything shorter and one weird traffic day skews it.
Use gut for the hypothesis, Experiments to confirm it.
Test it on one page first.
