Installed
SmartKDP is now on your Amazon book pages
Open any book, search result, or bestseller chart on amazon.com, amazon.co.uk, amazon.de and the extra figures appear in place. There is nothing to sign up for and nothing to configure.
What you will see
On search results
A strip under each book with its rank, price, reviews and format, plus a summary bar over the whole page — median price, review spread, and how much of the page is independently published.
On a book's page
Estimated sales and monthly royalty from the listed price and the book's rank, using the same printing-cost maths as our calculators. Trim size and ink are editable, because Amazon's page does not state the ink type at all.
On bestseller charts
Rank against estimated sales across the top slots, with price and format spread. On subcategory charts the rank column stays empty until you ask for deeper analysis — a #1 in a subcategory is often ranked in the tens of thousands overall, and printing the chart position as a sales rank would be badly wrong.
Turning any of it off
Every overlay has a Hide link in its own header — one click reveals the confirmation and a link straight to the matching setting, so you never lose track of how to bring it back. The full settings page (per-feature switches, which marketplaces are active, a light/dark override, and the diagnostics opt-out) is under Settingsin the extension’s toolbar popup.
What it collects
No account, no sign-in, and nothing that identifies you. The extension makes exactly two requests to us: one for its configuration, and one to turn a sales rank into an estimate — a number, a marketplace code and a category, never the book, never a search term. The full detail is in the extension privacy policy.
The rest of the toolkit
The calculators in the extension’s popup are the same ones on the site, and they run on the same code — a rate change lands in both at once.
