Amazon PPC clean-up kit

Find the Sponsored Products spend that is not selling and fix it in one upload: a checker that reads the bulk file you download from Amazon Ads and writes an upload-ready file of new negatives and measured bid changes, a report with the reason for every change, and the guides to run it every week.

What's inside

• PPC checker: a script that reads your Sponsored Products bulk file with search term data and finds search terms that spent more than one order's ad budget without an order, and keywords and targets running above or well under your target ACoS. It writes the negatives (negative exact keywords and negative product targets, at ad group level) and the new bids into an upload file in your own bulk file's layout, ready for Bulk operations.
• Break-even targets: a products sheet for your prices, VAT and costs, so each ad group's target and allowance come from your own break-even ACoS instead of a guess.
• Safeguards: brand terms, a keep list and your own keywords and product targets are never excluded automatically, bids move at most 30% down or 20% up per run, and paused and archived campaigns are left alone. Anything that needs a person goes in the report to check.
• Rules for 22 Amazon stores: currency, minimum and maximum bids and standard VAT rate for each store, from Amazon.co.za, Amazon.com and Amazon.co.uk to the EU stores, Amazon.ae, Amazon.sa, Amazon.in, Amazon.com.au and Amazon.co.jp, with every threshold in one file you can change.
• Guides: how each decision is made, with the maths and a worked example, and a weekly routine for negatives with a fortnightly one for bids.
• Agent skill: lets Claude Code or another AI agent run the checker and talk you through the report.
• Worked example: a made-up account with its bulk file, the report and the upload file the checker wrote for it.

Who it is for

Amazon sellers who run their own Sponsored Products campaigns and want a repeatable clean-up without a monthly tool subscription, and anyone who manages ads for clients and wants every change explained before it goes in.
