1. Amazon Flywheel Effect: Mechanism How Ads Accelerate Organic Growth
In evaluation axis of Amazon's search algorithm "A9", recent sales quantity (Velocity) occupies extremely high weight. D2C products immediately after release have low search ranking and exposure is limited, but by dropping Amazon ads and making sales performance "forcibly", it is possible to make algorithm recognize it as "product with demand".
Cycle where sales starting from this ad push up search ranking, thereby organic inflow increases, and sales grow further... is the Flywheel effect. Founders should evaluate ad cost not as mere cost but as investment in "intangible asset" called search superiority in initial phase.

- Sponsored Brands: Appeal brand's worldview utilizing brand logo and video. Contributes to promotion of cross-sell and inflow to store.
- Sponsored Display: Approach to competitor product pages and outside Amazon. Re-acquire withdrawn users by retargeting.

As indicator to measure efficiency of ad operation, ACoS (Advertising Cost of Sales) is common, but what D2C founders should truly pay attention to is "TACoS (Total Advertising Cost of Sales)".
Monitoring the ratio of ad spend to total sales (Ad Sales + Organic Sales) visualizes how much ads drive Organic Sales growth. Over-suppressing ACoS risks losing exposure and stopping the Flywheel, so aggressive investment decisions are required.
