A specific transition protocol for moving a listing from the expansion stage into the harvest stage of the Amazon Product Life Cycle (Launch, Expansion, Harvest): once organic ranking looks strong, deliberately withdraw support in stages and watch whether rank holds, rather than assuming it will.
One sequence used in practice: cut ad spend by roughly 10%, end running price discounts, and raise price outright (in one case from $32.99 to $39.99) — then watch sales and rank over the following weeks. If rank holds through the price increase and reduced discounting, that is direct evidence the ranking is now organic-demand-driven rather than ad- or discount-subsidized, and the harvest stage can proceed with confidence rather than guesswork. In the case observed, the stress test didn't just hold — spend was later increased again (ad spend roughly doubled) and revenue quadrupled off the now-validated organic base, taking the brand from single-digit daily units to 30-50 units/day.
Sophie Society's harvest approach for Study Key was incremental, not a single cutover: pull ad spend back by a step (e.g. 10%) and stop discounting, then watch whether organic sales hold. If they do, repeat the pullback; if organic sales sag, ease back off. The same gradual-step logic was applied to overall growth pace, not just ad spend — scaling the pace of expansion up gradually rather than pushing everything at once, treating the harvest test as a repeatable dial rather than a one-time switch flipped at the end of the Amazon Product Life Cycle (Launch, Expansion, Harvest).
