Amazon Affiliate Cookie Duration: How Attribution Works
A precise breakdown of Amazon's attribution window — including the part most other guides oversimplify or get wrong.
The base rule: 24 hours, or until one of three things happens
A tracking session begins the moment someone clicks your Amazon affiliate link. That session ends at the first of:
- 24 hours elapse, or
- An order is placed, or
- The visitor clicks through a different Associate's link before buying
If a purchase happens within that session, you're credited — this is the part most summaries get right.
The part most guides oversimplify: cart additions
Here's the nuance that's easy to get wrong: if a visitor adds a product to their cart during that initial 24-hour session, you're still credited if they complete the purchase within 89 days of the original click — but the item has to have entered the cart within that first 24 hours. This is not the same as a blanket "89-day cookie" that some secondary sources describe — the extension applies specifically to items already in the cart from the original session, not to any purchase made at any point within 89 days of a click.
Digital products are credited differently
For streamed or downloaded digital products, credit is based on the stream or download itself rather than a cart addition — a slightly different mechanism than the physical-goods cart-extension rule above.
Don't confuse this with the 180-day payout rule
Separately, Amazon's Operating Agreement requires a purchased product to actually ship (or be streamed/downloaded) and be paid for within 180 days of the purchase for the commission to be paid out at all. This is a fulfillment deadline — about when Amazon actually pays you for an already-qualifying sale — not an extension of the attribution window itself. Conflating the two is a common mistake.
What this means practically
The 24-hour session is genuinely short — a visitor who clicks today and buys next week, having never added anything to their cart during the original visit, isn't covered. The practical implication: content that drives an immediate purchase decision (a direct product recommendation, a clear call to action) converts more reliably under this system than content hoping a viewer "circles back later" without ever having added anything to a cart.
