Filter weak concepts before you spend a dollar, catch fatigue before CPA does, and keep the next wave ready — the full lifecycle audit for e-commerce creative.

E-commerce brands lose money on creative at three moments, and almost everyone only guards the last one. Before production — weak concepts get filmed because nobody filtered them on paper. During the run — fatigue announces itself in the leading indicators days before CPA moves, but most teams watch CPA, the coroner's report. At replacement time — the winner dies and the next batch is still being filmed, so the team keeps funding a corpse.

The 2026 stakes: creative is ~56% of incremental conversions, refresh cycles collapsed from 9 days to 3, top-quartile teams ship 80-120 variants a month.

Inside — an 18-check lifecycle audit:
• The pre-production filter — 6 checks that kill weak concepts at $0 (silent test, buyer's reason-to-care, share trigger, native shape, hook-before-shoot, matrix-planned)
• The early-warning signals — frequency creep, CTR decay from the creative's own peak, hook retention slippage, CPM rising at flat settings, first-time-impression ratio
• The variation audit — the 4-axis matrix that turns one concept into dozens of meaningful variants
• The pipeline discipline — the test lane, the bench-depth rule, the standing creator supply

The cheapest creative you'll ever kill is the one you killed before filming.
