Cost depends on category competition, keyword/product bids and your conversion rate. High-converting, well-positioned products achieve a lower ad share (ACOS) for the same budget.
Target ACOS should reflect your margin; pick a threshold that doesn't erode net profit. On low-margin products even 9% can be high. Our ad budget calculator computes your budget from target revenue and ACOS.
Start with a low test budget, shift budget to converting products/terms and pause inefficient ones. Strong visuals, competitive pricing and a high seller score directly improve ad efficiency.
There's no fixed price; cost is measured as ad share (ACOS) and varies by competition/category. A good level is usually below 9%.
Target revenue × target ad share (ACOS); our ad budget calculator does this automatically.
