Zero-Click Shopping and What It Means for DTC Traffic

Zero-click shopping gets talked about as one trend. It's three, and each one takes traffic away from DTC brands through a different mechanism. Brands still chasing clicks are focused on something other than the actual problem. Whether an AI system can read their catalog at all is the real challenge, since most catalogs were never built with that question in mind.

The often-cited figure that roughly seven in ten searches end without a click gets treated as a single, damning number, but it flattens three different shopper behaviors into one. Some searches end because the shopper found what they needed and moved on. Some end because the shopper refined the query and kept going, meaning the intent survives somewhere downstream. And some end because the shopper gave up. Averaging those three together produces a stat that sounds like a crisis and tells a brand nothing about what to actually fix.

The device split matters more than most dashboards admit. Mobile searches end without a click 77.2% of the time; desktop sits at 46.5%. Blend those into one report and the real story disappears, because mobile is where top-of-funnel research happens, and mobile is exactly where AI Overviews and answer engines are eating the most ground. A brand staring only at the blended number is diagnosing the wrong part of its funnel.

Two mechanisms get confused constantly, and the confusion leads brands toward the wrong fix entirely. A shopper who sees a product named inside a Google AI Overview and then types the brand straight into a browser is still a live conversion candidate. Standard analytics just can't see the path that got them there, so the visit lands in the dashboard as plain direct traffic with no context attached. That's an attribution gap, not a lost sale, and no amount of paid search spend fixes an attribution gap. A shopper who completes checkout inside ChatGPT without ever loading the brand's site is a structurally different problem: no page view, no pixel, no session. Treating both as the same crisis pushes a brand toward chasing more clicks, when the real fix for the first problem is better tracking, and the real fix for the second is making sure the AI has the data it needs to recommend the brand in the first place.

Google routes AI Overview referrals into the same bucket as ordinary organic search. There's no clean way to separate a click that came from an AI summary from a click that came from a traditional blue link, which means most DTC dashboards are undercounting AI-driven traffic right now, not because the traffic isn't happening, but because the measurement layer wasn't built to see it.

The traffic decline is real. The variable that decides who loses ground and who gains it is something other than click count. It's whether a brand's product data can be read, trusted, and cited by the AI surfaces now sitting between a shopper and a purchase.

Where the clicks actually go when AI Overviews appear, and why cited brands are winning

Most brands have this backwards: getting cited inside an AI Overview helps a brand, it doesn't cannibalize it. Brands that show up as citations earn 35% more organic clicks and 91% more paid clicks than brands competing on the same queries without one, according to Seer Interactive (September 2025). The traffic AI Overviews supposedly steal is landing somewhere else in the funnel, re-sorted toward whichever brand's data the AI trusts enough to name out loud.

That re-sorting runs on different rules than traditional SEO, and most brands haven't clocked the difference yet. Research into AI citation patterns has found that most URLs cited by AI platforms don't rank in Google's conventional top 10 for the same search. Ranking and citation are separate games, and a brand can win one while losing the other completely. Schema markup, the structured data tags that describe a product's attributes to a machine, has consistently shown up as a factor connecting product information to featured snippet appearances and AI Overview mentions. Schema looks like the actual mechanism connecting a product's information to its odds of getting quoted, not a technical nicety.

The gap this creates is wide. Audit data suggests a substantial share of brands that rank well in ordinary Google search results aren't cited by AI systems at all. Ranking and citation are not the same skill, and more than half the brands that mastered the former haven't started on the latter.

Cetaphil's approach shows what closing that gap looks like in practice. Instead of pouring paid search budget into landing pages built for clicks, the brand shifted spend toward pages built to answer the exact questions that trigger AI Overviews, testing conversational explainers designed to get summarized, not just visited.

Traffic that zero-click search takes from one brand doesn't vanish. It goes to a competitor whose catalog was legible enough for the AI to quote. And the gap between doing something about this and knowing whether it works remains wide: Many marketers say they're already optimizing for AI search, but far fewer are measuring whether that optimization does anything. Most of the industry is flying on instinct, and instinct is a poor substitute for a citation audit.

Why the catalog that was built for human browsers is invisible to AI surfaces

AI answer engines don't browse a site the way a person does. They retrieve. A retrieval system pulls from whatever data is structured, complete, and machine-readable, and it skips everything else, no matter how good the product looks in a lifestyle photo.

That's a real problem, and the fix isn't cosmetic. A product attribute like "color: blue" loses to a competitor's listing that says "deep navy, fade-resistant, suitable for outdoor use year-round," because the second version hands an AI model actual language to parse and repeat back. That gap is common across DTC catalogs: a product page can look complete to a human browser while remaining nearly invisible to a retrieval system. That's a catalog built with no expectation that a machine would ever need to read it, and the two problems require entirely different fixes.

Missing schema, the structured markup that flags product details, review data, and FAQ content, is widely treated as a key mechanism through which AI Overviews and Gemini surface product information, and its absence makes it far harder for a product to enter AI citation consideration. Skip them and the product doesn't rank lower than the competition. It's often just not in the running at all.

Fixing this takes a few concrete moves, not a redesign. Attribute data at the SKU level needs to go past title and price into material, use case, fit, compatibility, and sustainability claims, anything a shopper (or an agent shopping on that shopper's behalf) might actually ask. Q&A and use-case copy needs to sound like how people actually talk to these tools, the same logic behind Cetaphil targeting "how to get rid of dry flaky skin on face" instead of just "Cetaphil moisturizer." And review data needs structure and schema, since Amazon's Rufus already synthesizes review sentiment natively inside its own ecosystem, which means DTC brands selling outside Amazon have to make that same review data legible somewhere else, on their own, without Amazon's plumbing to lean on.

The tactics split by platform, too. Feeding ChatGPT means keeping Google Shopping feeds accurate, since that's where ChatGPT pulls from. Feeding Perplexity means earning citations from third-party sources beyond a brand's own domain, not just cleaning up on-site data. Feeding Gemini means ensuring product highlights and structured feed data align closely with shopper intent signals. ChatGPT currently accounts for a leading share of AI referral traffic among these platforms, which makes Google Shopping feed accuracy the sensible place for most DTC brands to start, not the place to stop.

Each of these requires ongoing work rather than a one-time project. A catalog that's enriched and structured gets cited today and keeps compounding as more AI surfaces move to retrieval-based discovery instead of traditional indexing. A thin catalog doesn't fall behind at the old pace. It falls behind faster, because every new AI surface is one more retrieval system it fails to clear.

Agentic commerce as the next layer (when the shopper's AI is doing the shopping)

The next layer past AI-assisted research is AI-executed purchasing: an autonomous agent handling discovery, comparison, payment authorization, and fulfillment from a single instruction, something like "order trail-running shoes under $150 that arrive Friday," with no human clicking through a single product page.

This isn't hypothetical. Salesforce data showed AI and agents influenced 17% of holiday orders over Thanksgiving weekend 2025, roughly $13.5 billion in sales. Rob Wingo of Salesforce summed up the pace of it: "We went from nothing to 17% in a year."

The infrastructure to run this is already live, and it's arrived faster than most retail infrastructure does. Visa's Trusted Agent Protocol, launched October 14, 2025 with Cloudflare, signs an agent's identity directly into HTTP request headers, and merchants check that identity against Visa's directory before completing a transaction. A payment protocol built with Stripe issues a token bound to one merchant and one dollar amount, time-limited and single-use, with the network already listing more than 850,000 retailers. Mastercard's Agent Pay runs on a similar structure, and Anthropic's Model Context Protocol, open-sourced in November 2024, has become the standard way AI assistants connect to outside data sources.

What matters most for a DTC brand here is who's doing the actual evaluating. In agentic commerce, the primary shopper looking at a product is an algorithm reading structured data, not a person scrolling a page. Product photography and landing page design, the things a DTC brand has spent a decade perfecting, carry zero weight with an agent that never renders the page visually. That should worry brands that have built their entire differentiation strategy around visual polish.

That shift carries real risk in the other direction too. Research from Cherep et al. (2025) documents systematic biases and model-dependent decision patterns in how AI agents choose between products, meaning the logic an agent uses to pick a winner isn't always transparent or consistent. Brands with richer, more structured data are better positioned when that logic stays opaque, simply because there's more for the agent to grab onto and less room for the model to guess.

A deeper tension sits under all of this, specific to DTC. Deloitte's 2026 Retail Outlook found a large majority of retail executives believe agentic commerce will weaken brand loyalty by 2027. For a business model built entirely on owning the customer relationship, an agent standing between the brand and the shopper is a major threat to that ownership. It's closer to an existential one. Salesforce's sixth Connected Shoppers Report found 75% of retailers already believe AI agents will be essential by 2026, which means the supply side is racing to catch up with a shift consumers have already made on their own.

How on-site AI converts the traffic that does arrive, and why the site experience still decides the sale

The large majority of AI-influenced sales still close on the retailer's own site, not inside the chat window. That number should reframe how a lot of brands think about this fight. The shopper does the research in ChatGPT or Perplexity or a Google AI Overview, then finishes the purchase where the brand actually controls the experience. The site is still where the sale gets won or lost, no matter how much of the discovery happened somewhere else, which means abandoning on-site investment to chase AI visibility is exactly backwards.

Research on on-site AI assistants has found that shoppers who engage with them convert at substantially higher rates than shoppers who don't, and they reach checkout noticeably faster. Returning shoppers who use these assistants tend to spend more per order as well. The same pattern holds from a support angle: merchants running shopping-assistant features, not just support-ticket bots, consistently outperform merchants running support-only automation on conversion.

A few brand examples make the pattern concrete. Kendra Scott's AI Copilot now resolves 93% of customer inquiries, up 53% from its previous version, and 6% of the brand's e-commerce sales are influenced by it, with revenue tied to those interactions up 160% year-over-year. Walmart's in-app shopping assistant has drawn significant early usage, and users of the feature carry a notably higher average order value than non-users. Spanx built an AI Stylist specifically to cut down on choice overload as its shapewear line expanded, and it more than doubled conversion rate while delivering a strong annualized revenue lift relative to what the brand spent building it.

None of this happens in a vacuum. Cart abandonment sits at a global average of 70.2%, a figure that's held remarkably steady across decades of measurement, according to Baymard Institute's September 2025 data. On-site AI that intervenes during the moment a shopper is deciding is attacking one of the oldest, most expensive problems in DTC commerce, not inventing a new one.

The two halves of this argument connect at exactly this point. The same structured product data that makes a catalog legible to ChatGPT or Gemini off-site is what makes an on-site assistant more accurate once the shopper actually arrives. A brand doing the enrichment work builds one asset that serves both audiences. It does the work once, and both the AI standing between the brand and the shopper, and the AI sitting on the brand's own site, get sharper as a result.

Measuring AI-influenced revenue when standard attribution doesn't see it

Attribution was already broken before any of this started. Per-channel ROAS overstates true return by roughly double the actual figure heading into 2026, and cookie deprecation is set to break most of the attribution setups brands still lean on. One industry summary put it bluntly: platforms claim 214% of a brand's revenue, when only 100% of it actually happened.

AI-driven traffic makes an already-broken system worse, not better. Shopify data from early 2026 shows AI-referred traffic to its platform growing sharply since January 2025, with AI-attributed orders growing even faster than the raw traffic. Chartbeat data shows ChatGPT referrals to publishers climbing sharply over the same window. Google still routes AI Overview referrals into the same bucket as ordinary organic search, though, which means the fastest-growing part of the funnel is also the part most dashboards are least equipped to see. Fixing the measurement gap matters just as much as fixing the catalog, because a brand that can't see where its AI-influenced revenue comes from will keep making decisions as if that revenue doesn't exist.
