<b>Lazy-load is fighting your floors</b>

Heard: aggressive lazy-loading fires ad requests just before viewport entry to juice viewability — but buyers bidding on predicted viewability now discount requests that arrive with no scroll-depth signal. High floors plus thin viewability context equals a quiet fill-rate drop on lower slots.

— Pre-fetch timing strips the context buyers price on
— Floor stays high, eligible demand thins

Impact: tier floors by slot position and pass a viewability-likelihood signal, or under-fill the fold. (rumor)
