"Switching killed my Core Web Vitals — but revenue's up"

"Switching killed my Core Web Vitals — but revenue's up"

Granted: short-term, heavier ad stacks can lift revenue while tanking CLS, and the cash is real this month.

But you've booked the revenue gain immediately and deferred the cost. Layout-shift and slow ad-injection erode rankings on a 2-to-4-month lag. The network that "out-earns" today does it by spending your future organic traffic — a balance you'll only reconcile after the rankings slide, when you've forgotten the switch caused it.

🚩 Hidden variable: the time-offset between the revenue lift and the traffic cost. They land in different quarters, so the dashboard never shows them on the same screen.

Gate any network on field CLS and INP, not just RPM. Revenue earned by borrowing from organic isn't earned.

Not saying the network is bad — saying the comparison is rigged.
