The point

More revenue per impression, not more impressions.

Less is often more with ad placement. Rather than adding slots or refreshing faster, Parallax makes a single impression worth more. It swaps a 300×250 for a 300×600 in the same viewport, with no layout shift and no change to ad density. Quality does the work: viewability climbs to 77.7% from 56.3%, viewable time grows 35%, and stronger signals lift CPMs and fill. Better impressions, not more of them.
