Google's In-AI Checkout Doesn't Kill Affiliate Links, SEO Columnist Argues

Google's Universal Commerce Protocol lets U.S. shoppers complete purchases inside AI Mode and the Gemini app without ever visiting a merchant's site — and that, not some algorithm tweak, is the real threat to affiliate commissions. The question landed in Search Engine Journal's Ask an SEO column this week: if the shopper never clicks your link, does the affiliate model survive?

The columnist's answer is yes — with caveats. "Affiliate links still matter, so make sure you keep using them," the column reads. The comparison drawn is Shopify's Google Direct Checkout: it changes the path to purchase, but it doesn't erase the need for the store behind it. The practical advice is to diversify monetization and work with brands that value more than raw clicks.

Why links survived before

This isn't the first time tracking has looked doomed. Cookie-based attribution started breaking years ago when mobile browsing took off — people researched on phones and bought on desktops, and the cookie never crossed devices. The industry answered with cross-device tracking, cart syncing for logged-in users, and server-to-server tracking. Networks experimented with login prompts tied to affiliate parameters, then fingerprinting. Streaming-TV affiliate companies went further, hashing IP addresses to connect sales back to partners.

The lesson, per the column: clicks don't always have to convert directly, but they add "levels of tracking security." Alternative methods now include IP hashing, vendors like TV Scientific and AudioHook, and vanity codes — though the writer warns codes leak onto coupon sites and browser extensions, and AI could surface them to traffic you never referred.

What does this change for practitioners?

Not much structurally, the argument goes — because third parties have always intercepted. TikTok Shop keeps purchases on-platform. Walmart's app inside ChatGPT does the same. Big-brand marketplaces let third-party vendors sell where you earn no commission at all. The columnist's advice is blunt: upload content natively to platforms where your vendors are synced, keep links on your own site, and simply drop programs that don't pay on third-party sales. "That is a choice you are knowingly making."

There's a trust angle too. The column cites its own outlet's finding that only 28% of Americans trust AI search. Younger audiences are disengaging from clearly AI-generated ads and content, and reviews are being gamed. Skeptical shoppers scroll past AI Overviews to human-created reviews and demos — especially for big-ticket items like bikes, software, and games. An affiliate disclosure can even be framed as supporting a real business rather than AI, which the writer says resonates with anti-AI consumers. It's also an FTC requirement in many cases, so the compliance and marketing incentives align.

The tracking reality check

Here's what the column doesn't sugarcoat: your click can still vanish. Browser extensions wipe cookies. Other affiliates overwrite your click with their own extensions. Merchants let coupon sites claim credit at the last second. Properly configured programs recover the first click in many cases, and multi-touch tools like ThoughtMetrics (which the writer discloses using with no business relationship) map every touchpoint, including repeat purchases for lifetime value.

One program the columnist works with reconciles monthly and manually credits anything that didn't track automatically. No click, no claim — and less money.

The takeaway isn't that links are bulletproof. It's that they remain the first line of defense in a commission model that keeps adding technical layers. As checkout moves inside Gemini and AI Mode, expect tracking vendors and affiliate programs to race to build the attribution equivalents of what cross-device tools became after mobile broke the cookie — assuming, of course, that shoppers keep trusting AI enough to buy there at all.
