The affiliate commission is changing hands, and the new hands did not build the business. For twenty years the money went to whoever ranked — the review sites, the listicle farms, the affiliate desks of old magazines, each engineered to sit at the top of a Google result. AI-written answers and Substack are now rerouting it to writers who own an audience instead of publishers who rank for one.

The first blow is a click that no longer lands. By early 2025, roughly one in five Google searches was resolving inside an AI summary, and Pew Research found that those searches sent a reader to a traditional result 8 percent of the time, against 15 without the summary. The links cited inside the summary drew a click in one visit out of a hundred. An affiliate listicle’s whole product was the ranked page, and the machine now reads it back to the shopper for nothing.

This was always the model’s weakness, sold as its strength. The affiliate publisher never owned its readers; it owned a position, and Google owned the readers. When HouseFresh accused larger publishers of flooding the web with product recommendations — many untested, many produced by third-party vendors — to harvest affiliate commission, it was describing tenants who had mistaken a long lease for a deed.

Google has since begun penalising them directly. Its site reputation abuse policy, enforced from May 2024, demoted the arrangements by which a trusted domain lets a commission desk borrow its authority; CNN, Forbes and the Wall Street Journal have all since felt it. The host can withdraw its name faster than the borrower can build one.

The easy verdict is that AI is killing the publisher. It is doing something more selective. The sites in trouble rented their audience from Google; the writers who thrive never needed Google to assemble theirs. Substack passed five million paid subscriptions in March 2025, up from two million in 2023, and a paid subscriber is the asset no ranking can grant: a reader who comes back without being found.

In fashion and beauty, the relocated commission already has its infrastructure. ShopMy moves more than a billion dollars a year through 200,000 creators selling to audiences they own, and raised $77.5 million in January. The brand still pays a commission; it now pays a different party, at a different moment, for a sale no search engine ever saw.

A newsletter cannot be deindexed.

All of this leaves brands crediting the wrong moment. Affiliate budgets are built on the last click, the final link before the sale, and that link is now a machine that cites without sending or an inbox that sells without a search. What last-click attribution credits is not the source of the demand — it is the last door the buyer walked through. The party that made the sale and the party that booked the commission have come apart. A brand can no longer tell whether the commission bought a customer or merely tagged one it already had.

The click told a brand where a sale had passed. It could never tell whom the buyer would trust next, and that trust now decides where the cut lands.
