Nobody has a settled answer yet. Three launches show where attribution is heading: Evertune and impact.com's Partner Connect shows brands which publishers shape AI answers, Google's Universal Commerce Protocol lets AI agents complete purchases, and Partnerize's VantagePoint measures influence beyond the click.
For two decades the affiliate contract was simple: traffic, click, cookie, conversion. When a shopper reads your review inside an AI answer and an agent completes the purchase, you influenced the sale and never got the click.
Evertune and impact.com: seeing who shapes the answer
The news. Evertune and impact.com launched Partner Connect, which shows brands which publishers appear most often in AI answers for their category. Sources: Evertune's announcement and impact.com's press release.
What it could lead to. Once a brand can see that a publisher shapes AI answers, it has a reason to pay for that influence directly, through flat fees or higher commission tiers. That is speculation. No platform has announced a payout model built on citations.
Google: the agent is the buyer
The news. Google announced the Universal Commerce Protocol and Business Agent tools in January 2026. They let AI agents complete purchases across retailers without the shopper visiting each site. Source: Google's announcement.
What it could lead to. If an agent executes the order, there is no affiliate link in the path. Publishers whose product data an agent can read, with clear pros, cons, and best-for guidance, are better placed to be the source the agent relies on. How that source gets credited is still an open question.
Partnerize: measuring influence without a click
The news. Partnerize launched VantagePoint, which it describes as a way to quantify a publisher's influence beyond the click.
What it could lead to. If brands can measure content that informs a later purchase, some publisher deals may move away from pure cost-per-action toward payment for mid-funnel influence. That is also speculation.
What to do now
- Track where your content is cited in AI answers. The comparison page lists tools that do it.
- Ask your affiliate platform what it offers for AI visibility. impact.com and PartnerStack both have integrations.
- Keep product facts on your pages clear and current, since that is what an answer engine or agent quotes.
