Drop your Amazon Sponsored Products reports. Every bid is set from what a click actually earns, you get the three fixes worth doing first, and no number is inflated.
No guesswork and no black box. What a click earned, times the share of sales you are willing to spend, is what that click is worth to you.
The same keyword converts very differently at the top of search and on other products' pages. The desk sets placement adjustments from what each placement earns per click.
Each fix shows what it is worth a month as a range, assuming conversion stays as it is today, and how many orders that rests on.
The fixes are not added into one total. A bid cut and a placement change touch the same clicks, and moving a search into exact match shifts sales that already happen. A sum would count money twice.
Nothing to install and no account to connect.
Same date range, summary view, from Seller Central.
The desk recognises each report and the currency, checks the dates match, and runs every calculation on your own computer.
Tick the changes you agree with and download a bulk file holding only the changed rows. Nothing reaches your account until you upload it.
About a minute once your reports are downloaded. Free, and your files stay on your computer.
