<b>The anchor ad is eating your Core Web Vitals</b>
Ok so the sticky bottom anchor — everyone leaves it on because it prints. But it ships late and shoves layout when it pops in. Watched a content site tank CLS from 0.04 to 0.19 just from that.
Fix: reserve the height. Drop a fixed-height div where the anchor lands so the page doesn't jump.
— RPM held, CLS back under 0.1
— rankings stopped slipping
Test it on one page first.
