This completely depends on the search term volume, product fit, clickthrough rate, competitiveness of the market, etc. We generally see Sponsored Product ads as the primary drivers early on, Coupon-driven traffic is basically a game that Amazon controls exclusively, other types of ads are helpful in increasing your brand glow and awareness on and off of Amazon. Our goal is generally to get from Growth Mode, where we are primarily driving traffic via ads and have a blended ACoS from 20-30%, to ‘post growth mode’ where blended ACoS would shift to 8-10%, at which point we would try to ensure sales velocity is sustained and dial back our paid ads to focus on optimization over time, improving the ratio steadily.
