Stories cost 40-60% less per reach but decay in 24h

Feed post ██████ permanent | Story ███░░░ 24h | Reel █████░ algo-fed

Three formats, three economics. A feed post compounds — search, profile visits, saves keep working. A story spikes then dies.

— Feed CPM: $11-19, long tail of reach
— Story CPM: $5-9, 80% of views in first 6h
— Reel CPM: $7-13, unpredictable distribution

Stories win for time-sensitive drops and swipe-up traffic. Feed wins for evergreen product launches you'll reference later.

So what: match format decay to offer shelf-life — don't burn a permanent slot on a 48h promo.

Benchmark: n=180 placements — story 24h reach = 31% of feed 30-day reach.
