How much has Amazon cut Associates commissions?

According to Adweek's May 2026 reporting, Amazon has cut Associates commission rates by as much as 50% in several categories as part of a multi-month restructuring of the affiliate program. eMarketer confirmed the scope on May 20, 2026 and AdExchanger flagged it in its May 19 daily roundup.

Has Amazon also changed how affiliate attribution works?

Yes. Since April 14, 2026, onsite commissions are calculated only on purchases of the promoted ASIN or its variants. Same-category purchases (for example a different toaster bought after clicking a kettle review) no longer count toward onsite earnings. This removes the implicit halo bonus publishers used to rely on.

Does this affect third-party Amazon sellers directly?

It does not change your seller fees, but it materially changes the creator economy that drives external traffic to your listings. Expect a thinner top-of-funnel from review sites and creators, more pressure on Brand Referral Bonus efficiency, and more aggressive negotiation from creators who now want flat fees instead of pure Associates cuts.

What should brands do about Brand Referral Bonus now?

Re-baseline BRB-eligible revenue per SKU and per traffic source in your own analytics. The 10% bonus still applies on qualifying external-traffic orders, but the pool of creators driving those orders is shrinking, so you need a clean read on which SKUs and which sources still pencil out.

How should I restructure creator deals after the Associates cut?

Move away from Amazon-only commission deals. Lead with a per-post fee, then layer Brand Referral Bonus-shared upside or a multi-marketplace split (Amazon + Walmart + DTC). Top creators will not stay on a halved Amazon-only commission, especially with same-category attribution gone.

What's happening

Over the past several months, Amazon has quietly restructured its Associates affiliate program, cutting commission rates by as much as 50% in some categories and stripping out the same-category attribution that publishers and creators had relied on for years (Adweek's full breakdown). The pattern with these announcements: cockpit views show the impact before sellers get the email from Amazon.

EMarketer confirmed the move on May 20, 2026, framing it as a direct hit to publishers that built affiliate commerce businesses around Amazon shopping content (eMarketer analysis). AdExchanger called it "alarming" in its May 19 daily roundup (AdExchanger roundup) and Hello Partner reported on May 20 that affiliates are also losing reporting visibility on top of the rate cuts (Hello Partner report).

For brands, this is not a creator problem. It is a customer-acquisition problem. The affiliate funnel that quietly carried millions of qualified shoppers to Amazon product pages is being repriced in real time.

Why this matters for Amazon sellers

The Associates program is not a side channel. It is one of the largest paid-discovery surfaces feeding Amazon product pages, and it sits right next to the Brand Referral Bonus economics every external-traffic strategy depends on.

Layer	What changes	Action for sellers
External traffic	Creators who relied on Amazon-only links will diversify to Walmart, Target, brand DTC. Some will simply stop covering Amazon SKUs.	Audit which top-of-funnel articles ranked for your ASINs and whose disappearance you would feel.
Brand Referral Bonus	BRB still pays sellers a bonus on external-traffic conversions, but the creator pipeline that feeds it just got more expensive to keep alive.	Re-baseline BRB contribution per source against a leaner affiliate ecosystem.
Same-category halo	A reviewer linking your kettle no longer earns on the toaster the reader bought instead. The implicit catalog bonus is gone.	Pay creators per-ASIN or per-collection, not per-session.
Direct creator deals	Cuts make Amazon-only deals less viable; creators will push for flat fees, brand sponsorships, or multi-marketplace splits.	Decide a creator-payment posture (flat fee, hybrid, BRB-shared) before Q3 negotiations.
SKU-level attribution	With same-category attribution gone, performance reporting is now strictly ASIN-bound; assumed halo lift disappears from creator dashboards.	Track which ASINs actually convert from off-Amazon sources at the SKU level in your own analytics.

This sits alongside the broader Amazon shift toward monetising its own AI surfaces. See our coverage of Brand Referral Bonus expansion, Rufus ads monetisation, and Alexa for Shopping for the full picture of where Amazon is redirecting its traffic-acquisition spend.

What you should do this month

1
Map your top external-traffic ASINs
Pull the SKUs that historically convert off Amazon, then check which ones depend on creator content using Associates links. Use Winners & Losers to isolate movement at the ASIN level.
2
Re-baseline Brand Referral Bonus contribution
BRB still pays 10% on qualifying external-traffic orders, but with a smaller creator pool feeding the funnel, you need a clean read on BRB-eligible revenue per SKU in Profit & Loss.
3
Shift creator deals to flat fees or hybrid splits
Amazon-only commission is no longer a sufficient incentive for top creators. Lead with a per-post fee + BRB-shared upside, not a pure Associates cut.
4
Diversify the off-Amazon discovery mix
Walmart Connect, TikTok Shop and direct DTC are absorbing some of the creator output. Build the read on those channels in Custom Breakdowns so you see channel mix shifts as they happen.
5
Lock SKU-level contribution margin
If you have to backfill lost affiliate volume with paid media, you need to know exactly how much margin each ASIN can absorb. Reconcile 40+ Amazon fee types at the SKU level in Profit & Loss before you raise bids.
