Amazon Sponsored Products audit

Your campaigns are bidding against each other. Find out where — in fifteen minutes, without sharing your data.

BidWar Audit reads your Sponsored Products Search Term Report and pinpoints cross-campaign keyword overlap (internal bid wars). The CSV is parsed in your browser — we never receive the file, your account, or your numbers.

Privacy by architecture

Most PPC tools want OAuth into your Amazon Advertising account. We do not. BidWar Audit cannot read your account, your campaigns, or your historical data — by design. The only path your numbers take is browser → Web Worker → on-screen report. We store your email (for the magic link) and the Stripe payment metadata. Nothing else. The detection code is open-source so the claim is verifiable, not promised.

FAQ

What is "internal bid war"?: When two of your own Sponsored Products campaigns target the same search term — manual broad and an auto campaign, for example — you bid against yourself, paying more per click than the same keyword would otherwise cost.
How does my data stay private?: The CSV is parsed in your browser using a Web Worker. The detection algorithm runs on your machine. The only thing our server receives is your Stripe payment confirmation and the email used for the magic link.
Which Amazon report do I need?: Sponsored Products → Reports → Search Term Report. Date range your choice — last 30–60 days is typical. Save as CSV.
How accurate is the dollar-impact estimate?: It is a range, not a single number. Lower bound assumes all overlapping spend was redundant; upper bound assumes none was. The truth sits somewhere between — the report explains the math.
Can I get a refund?: Yes — within 7 days, no questions asked, if the report did not deliver actionable findings. Email support and we will refund via Stripe.
