Most Amazon PPC tools take 3 to 15 percent of your ad spend. The more you spend, the more they earn: their incentive is not aligned with yours.
SellerPPC started when its founder, an Amazon seller, watched his PPC tool triple its price. He built his own engine, ran his store on it, then opened it to other sellers.
What it does every morning:
Evaluates every keyword across two windows (7 and 30 days)
Adjusts bids with a proportional formula: bid x (target ACoS / actual ACoS), never a blind +10 percent
Promotes winners through a real AUTO to PHRASE to EXACT funnel, with anti-cannibalization negatives
Negates search terms that accumulate clicks without converting
Reallocates budgets by 7-day ROAS
Schedules native dayparting through Amazon Bid Rules and Budget Rules
Requests reviews automatically via the official SP-API
Connects to Claude and ChatGPT through MCP
Automation without the black box: Safety Caps bound every change, a 5 to 7 day cool-down lets data stabilize, and the Audit Log records who, when, why, with before and after values. Approve or revert in one click.
