Turned on anchor ads — mobile only — and left desktop alone
Tried this today on a 60/40 mobile-skewed blog. Enabled the bottom anchor unit in auto ads but capped it to mobile, killed it on desktop where it just annoyed people and tanked nothing useful.
— Mobile anchor on, desktop anchor off
— Session RPM mobile $6.20 → $7.40
— Desktop untouched, no complaints, no layout shift
The anchor prints on mobile because the thumb is already down there. Don't let it ruin your desktop. Test it on one page first.
