Case: adding a sticky floating outstream video player

What it did: a single outstream video unit that floats to the corner when the in-content player scrolls off, on long guides.

— Setup effort: 3/5 (player + float-on-scroll logic, close button)
— RPM lift seen: page RPM $13.00 → $17.60 (+35%) — video CPMs dwarfed display
— Completion-eligible views tripled vs the static in-content player

Pros: video CPMs are the single biggest RPM lever here; the float captures the whole scroll.
Cons: heaviest JS payload of anything tested (LCP +0.3s); intrusive if it autoplays with sound (don't — muted only). Some readers complain.

Lift: ★★★★★ — Risk: ★★★☆☆
Verdict: the highest-ceiling lever, but muted + closable + lazy-loaded only. Best for: long content with patient readers. Skip if your CWV budget is already tight.
