'Currently unavailable' on a top pick burns the whole page's EPC

'Currently unavailable' on a top pick burns the whole page's EPC
The failure: your #1 recommendation goes unavailable, but it's still the first link readers click. They land, can't buy, and don't scroll back for #2.
— Pages where the top pick was unavailable: page-level conversion 1.1%, n=430 page-days
— Same pages with top pick in stock: 4.3%
The top link absorbs the majority of clicks, so one dead pick tanks everything below it.
Fix: monitor availability of your #1 picks weekly; auto-swap or visually demote an unavailable item so clicks flow to a live one.
So what: availability of your single top link drives most of a page's earnings — watch it, not the whole list.
