Amazon seller benchmarks — from real accounts, not surveys

Median settled ACoS across seller accounts with meaningful ad sales (10 accounts; windows end 7 days back so Amazon's late attribution doesn't inflate the number). Range: 24% to 111%. Most portfolios run far hotter than the "25-30%" survey averages quoted around the web.

Share of the last 30 days' search-term spend sitting on terms with 15+ clicks and zero attributed orders — enough evidence to call them wasters. Roughly one rupee in nine buys clicks that have already proven they don't convert.

Same window, all search terms with zero attributed orders regardless of click count. The gap between this raw figure and the 10.8% proven share is why negating on thin data destroys campaigns: most zero-order terms just haven't had enough clicks to judge.

Across 14,762 hourly Buy-Box checks in the last 30 days, sellers did not hold the box in 11.7% of checks — one in nine buyer visits landing on someone else's offer.

Right now, 104 of 152 products holding FBA units on the platform cannot sell due to listing problems — heavily driven by a few accounts with bulk listing errors, which is exactly how stranding happens in the wild: not evenly, but in silent batches.

Of 9,783 FBA units tracked, 4.5% sit in the 181+ day age buckets — the window where Amazon's long-term storage surcharge is either imminent (181-270 days) or already billing (271+).
