Fair: a real network upgrade compounds, so October feels validating.

But Q4 ad spend ramps every year regardless of who serves your ads. CPMs climb 30 to 60% from October into December on calendar alone — Black Friday, holiday retail, end-of-budget dumping. Switch right before that wave and the rising tide gets credited to your new network.

🚩 Hidden variable: the ad-spend calendar, not the network. The honest test is year-over-year same-month, old network vs new, not month-over-month across a seasonal cliff.

The cruelest version: people switch in October, ride Q4, then panic in January when RPMs "crash" — that's just spend normalizing, not the network failing.

Not saying your timing was wrong — saying the comparison is rigged.
