On April 14, 2026, Amazon made one of the most consequential changes to the Associates program in years โ and most affiliates found out only when their earnings shrank. The "halo commission" is gone: Amazon now pays only on the exact product you linked, not on the other items a reader happened to add to their cart in that session.
This is confirmed on Amazon's own Associates Central "What's Changed" page, effective April 14, 2026. It's separate from the separately-reported rate-card cuts of up to 50% that Amazon has not publicly confirmed. This guide explains what changed, what it means for your earnings, and how to measure the real impact on your own account.
Before April 14, when a reader clicked your link and bought anything in that session, you earned commission on the qualifying items they bought โ including products you never mentioned or linked. It was the quiet upside of Amazon affiliate marketing: link a $30 kettle, and if the same reader added a $200 espresso machine to the cart, you earned on both.
It was invisible, it padded nearly every click, and it made your real earnings per click higher than the category rate alone suggested. That's why so many people never noticed it was happening โ and why so many didn't realize the day it stopped.
Amazon's Operating Agreement update changed the calculation of onsite commission income to apply only to Direct Qualifying Purchases of the same ASIN variant as the linked product detail page. In plain terms:
The same update made three other changes worth knowing about:
This is the trap: the halo change can cut your earnings without any visible rate change. Your category rate can look identical and your payout can still fall, because the "extra" items you never linked no longer pay. Publishers have reported income drops around 25% in the months after the change, with the loss concentrated precisely in the cart-wide income that never appeared on any rate table.
That's why checking a rate table isn't enough. The halo loss only shows up in your actual transaction data โ as a line item whose reported commission is lower than what the rate on that order's date should have produced.
The reliable way to quantify the halo change is to compare what you were actually paid against what the published rate should have produced for your order dates:
Everything runs locally โ nothing is uploaded, no account, no sign-up.
Halo commission was the commission Amazon paid on other qualifying items a referred reader bought in the same session, beyond the product you linked. It ended April 14, 2026.
No. Since April 14, 2026, onsite commission applies only to Direct Qualifying Purchases of the same ASIN variant as the linked product detail page.
No. The click window is 24 hours with a 90-day cart carryover. The 180-day figure is a deadline for products to ship, stream or download and be paid for โ not extra time to shop.
The Operating Agreement update was published on Amazon's "What's Changed" page. The separate reported rate-card cuts of up to 50% were reported by Adweek and other outlets but have not been publicly confirmed by Amazon.
