<b>Reserve the ad height or you're paying twice</b>
Ads with no reserved space cause layout shift — content jumps when the ad loads. That CLS hit hurts Core Web Vitals AND triggers accidental clicks Google later claws back as invalid.
Set a fixed min-height container for every manual unit (even responsive ones, give it a floor).
— CLS dropped from 0.21 to 0.04
— invalid click warnings stopped
— rankings nudged up over a month
No content jump = cleaner clicks = healthier account. Test it on one page first.
