Amazon Attribution
See which ads outside Amazon — Facebook, TikTok, Google, your newsletter — bring Amazon sales, Kindle Unlimited pages and royalties, and what each one cost.
What it measures
Amazon Attribution is Amazon's own measurement of sales that come from outside Amazon. You put a special link in your ad, email or post. When a reader clicks it and buys or reads on Kindle Unlimited within 14 days, Amazon credits that link.
TrueRoyalties reads those results every day and shows, per link and per book: clicks, how many reached your book's page, orders, pages read, the royalties they represent — and, when the link is used by a Facebook or TikTok ad you connected, what that ad cost.
These royalties are already inside your KDP royalties. The page shows which part came from your ads outside Amazon. It never adds anything to your net profit.
Before you start
- Connect Amazon Ads first. Attribution uses the same connection: there is nothing new to authorize.
- Amazon offers Attribution to KDP authors on the US, Canada, UK, Germany, France, Italy and Spain stores. Not in Australia or Japan. The line under the page title lists the stores your links are on.
- Amazon only measures clicks on links that carry an Attribution tag. A plain Amazon link in your ad is not measured. Links you created yourself in the Amazon Ads console are measured too.
Connect
Open Platforms in the sidebar and click Connect on the Amazon Attribution card. Its page then appears under Marketing in the sidebar.
The first import brings back up to 13 months of history, then the page updates once a day, as Amazon does. Update now, next to the date of the last update, asks again at most once an hour.
Get a link to use in your ad
- Under Generate an Attribution link, choose the book, the marketplace, where the link will be used, and a campaign name only you will see. The marketplace starts on the store where your links already are.
- Click Generate the link. It appears under Links created in TrueRoyalties, with the exact text to paste and where to paste it.
What you paste depends on where the ad runs:
| Where the link is used | What you copy | Where it goes |
|---|---|---|
| Facebook Ads | A line of URL parameters | The ad's URL parameters field (Tracking section) in Meta Ads Manager. Keep your Amazon book page as the destination |
| Google Ads, Microsoft Ads | A tracking template | The campaign's tracking template. Keep your Amazon book page as the final URL |
| Pinterest Ads | A line of URL parameters | The ad's URL parameters or tracking field |
| TikTok, email, blog, YouTube and the rest | A complete link | Use it as is, as the destination of the ad, email or post |
Three rules from Amazon, worth following:
- One link per marketplace. A link made for the US store measures nothing on amazon.co.uk.
- One link, one book page. Never point a link at a different page. To send readers somewhere else, generate a new link.
- Generating a link turns on Attribution measurement on your Amazon Ads account for that marketplace. That is what makes it count.
Remove only takes a link off your list in TrueRoyalties. Amazon keeps measuring any ad that still uses it. Links created in the Amazon Ads console are not in that list — Amazon does not share their address — but their results are in the tables.
Read the results
| Figure | What it means |
|---|---|
| Clicks | Clicks on your Attribution links, and the share that reached your book's page on Amazon |
| Orders | Orders Amazon credits to those clicks, the conversion rate (orders ÷ clicks), the same rate with Kindle Unlimited reads added, and the retail value of the sales |
| KENP pages read | Kindle Unlimited pages read after a click, and how many full reads that is |
| Attributed royalties | The part of your KDP royalties those orders and pages earned |
| Linked ad spend | What the Facebook and TikTok ads linked to your links cost |
| Return on linked spend | The royalties of the links that have a linked ad ÷ what those ads cost |
The dates follow the date range and currency at the top of the page.
Full reads are the KENP pages divided by the book's page count (KENPC). KDP shows the KENPC on your Bookshelf, not in its reports: add it once per book in the By book tab, and the reads appear.
Until an ad is linked, the last two figures give way to a card that says what to do: connect Facebook Ads or TikTok Ads, or link your ads to your links.
Over time
One bar per day, or per week when the period is longer than 45 days. Pick the figure above the chart: clicks, book page views, orders or KENP pages.
By link
One row per link, with the book it sends readers to. Click the arrow to see which books it sold and which ads use it.
Book page views is the number worth watching first. When fewer than half of a link's clicks reach the book's page, the share turns orange: readers are lost on the way — check where that link lands.
Links with fewer than 10 clicks and no result are folded under Show quiet links.
Link an ad to a link
Spend is matched automatically when the ad is in a Facebook or TikTok account you connected, and its tag carries the ad's own ID:
- Facebook: a link generated here puts the ad's ID in its parameters, so every ad is matched to its row.
- TikTok: the complete link you pasted is matched to the ad that uses it.
A link created in the Amazon Ads console cannot be matched automatically. Open its row and click Link an ad, then choose the ads that use it. An ad is linked to one link only: linking it again moves it.
Each linked ad says how it got there — linked by you or linked by its tag — and one you linked can be unlinked from its badge. When several ads share one link, the row says so: its results belong to all of them together.
By book
Attributed royalties are calculated from KDP, not from Amazon's sales value:
- each unit Amazon credits earns what that book actually earned per unit, on that marketplace, over the period;
- never more units than KDP recorded — when Amazon counted more, the row shows both numbers;
- for Kindle Unlimited, we keep Amazon's estimate for the pages read, capped at the Kindle Unlimited royalties KDP paid you for that book and marketplace.
A sale is credited to the book the link lands on. When a link lands on several books, or on one Amazon never named, its sales are counted under the table instead of being guessed onto a title.
When a figure is 0 or missing
When there are clicks but no order and no page in the period, a box at the top of the page says when Amazon last credited one, how many clicks reached the book's page, and whether the last days are still being counted.
| What you see | Why |
|---|---|
| Every figure is 0 | Amazon shows 0 for a link until it has had 10 clicks in total, to protect shoppers' privacy |
| Clicks but no orders yet | Clicks appear within 24 hours, orders within 48, and an order counts up to 14 days after the click. Amazon also corrects the last 28 days, and we re-read them daily |
| Few book page views | Most clicks never reached the book's page: check where the link lands |
| No book under a link | Amazon has never named the book this link sells (it names books for its last 90 days only) |
| No full reads | The book has no KENPC yet: add it in By book |
| No spend on a link | No Facebook or TikTok ad is linked to it: link one from its row |
| "No Attribution link has recorded a click" | No link with an Attribution tag was clicked in this period |
Two more limits. Amazon only credits clicks — someone who saw your ad and searched for the book later is not counted. And a sale is credited to the last Attribution link clicked in the 14 days before it.
