Amazon Attribution: what it measures and where it stops

Amazon Attribution answers a real question: which of your external ads sent people to Amazon and got them to buy. What it can't do is tell Meta what it just learned.

What is Amazon Attribution?

Amazon Attribution is a free measurement tool inside Amazon Ads that tracks how non-Amazon traffic performs once it reaches an Amazon product page. You tag your Meta, Google, TikTok, or email links, and Amazon reports what those clicks did after they landed: page views, add-to-carts, and purchases.

It exists because Amazon owns the checkout. When a shopper buys on Amazon, the sale is recorded on Amazon's servers, not yours. Attribution is Amazon's way of crediting the outside source that drove the visit, and it's the closest a seller gets to watching an external ad turn into an Amazon order.

For brands running Meta ads to Amazon listings, this is the only first-party view of what happened at the retailer. The ad platform sees the click leave. Amazon sees the checkout arrive. Amazon Attribution is the report that ties the two ends together, on Amazon's side.

How do Amazon Attribution tags work?

You create an attribution tag for each ad, publisher, or campaign inside the Amazon Ads console. The tag is a tracked URL that points at your product or Store page. You paste that URL into your Meta ad in place of the plain Amazon link.

Every click on the tagged link routes through Amazon's measurement layer before landing on the listing. Amazon matches that click to any downstream activity in the same shopper's session and rolls it up under the tag you named.

The report you get back covers a fixed set of metrics.

For eligible brand-registered sellers, this data also feeds the Brand Referral Bonus, which averages about 10% back on sales driven by your own external traffic. That alone makes the tags worth setting up, before you even count the reporting value.

Where does Amazon Attribution stop?

Three limits matter, and none of them are bugs. They are the shape of the tool.

The first is delay. Amazon Attribution reporting is not real-time. Data lands in the console on a lag, often a day or more, so you're reading yesterday's performance rather than this morning's. For a campaign making bid decisions hourly, that gap is real.

The second is scope. The tags measure the traffic you send to Amazon and nothing else. A shopper who sees your ad, buys on Amazon this week, then reorders through Subscribe & Save next month is largely invisible to the tag once the attribution window closes. You see the first order, not the customer.

The third limit reshapes everything: direction. The data flows one way. It lands in Amazon's console for you to read. It never travels back to Meta.

Why doesn't the data reach Meta's delivery system?

Meta's delivery learns from conversion events sent to your ad account. Its algorithm decides who sees your next ad based on who converted on your last one. Feed it purchases and it hunts for buyers. Feed it nothing and it falls back to hunting for clickers.

Amazon Attribution never sends a purchase event to Meta. The conversion sits in Amazon's console, readable by you, unreadable by the delivery system that spent the money. So Meta keeps steering budget toward people who click, because clicks are the only signal it can see. This is the same blindness described in what happens to Meta's algorithm when you sell on retailers, and it compounds every day the campaign runs.

The result is two ledgers that never reconcile. You can open Amazon Attribution and see that a specific ad drove 40 Amazon orders. You can open Ads Manager and see that same ad report zero conversions. Both are correct. Neither talks to the other, which is exactly the gap that off-site ROAS tries to name: real revenue landed somewhere your platform reporting can't count it.

How to read Amazon Attribution alongside your ad platform

Treat Amazon Attribution as the retailer-side scoreboard and your ad platform as the delivery engine. They answer different questions, and you need both.

1. Use Amazon Attribution to judge which external sources actually produce Amazon sales, since it's the only place that truth is recorded.
2. Use the attribution report to reallocate budget by hand, pausing tagged links that drive clicks but no orders.
3. Watch the reporting lag. Give each tag enough days of data before acting, because same-day numbers are incomplete.
4. Accept that manual reallocation runs slower than algorithmic delivery, and that the platform's automation keeps steering on click data unless you close the loop back to it.

That last point is the real work. Reading Amazon Attribution well tells you what happened. It doesn't teach Meta anything. Closing that second gap, feeding retail purchase signals back into the delivery system, is the complement to Amazon's tags rather than a replacement. One measures. The other steers.
