ChatGPT, Perplexity, and Google AI Mode now handle tens of millions of shopping queries every day, and AI-referred shoppers convert 31% better than those from traditional search. Here's what the shift means for your marketplace, and exactly what to do about it.
TL;DR (Too long; didn't read)
- Buyers are no longer searching on Google for their queries. Instead, they're asking ChatGPT, Perplexity, and Google AI Mode about what to buy, where to buy, and how to buy. And those AI-referred shoppers convert 31% better than regular search traffic - that's a fact.
For marketplace founders, the catch is that AI recommends products based on data quality, not ad spend. Incomplete vendor listings, missing product schema, inconsistent pricing, and no reviews = invisible to AI.
What to do:
- Add a complete Product schema (JSON-LD) to every listing
- Enforce product data quality standards on your vendors
- Fix price consistency across your site and Google Merchant Center
- Build review infrastructure, AI uses it as a trust signal
- Write answer-ready category and buying guide content (this is GEO)
If you're on Shopify, your products already sync to ChatGPT automatically, but syncing ≠ is recommended. Your product data quality is what decides that.
The marketplaces that clean up their catalogues now will have a head start. The ones that wait will wonder why no one's finding their products in two years.
Not long ago, buying something online followed a fairly predictable script. You'd type something into Google, open six tabs, read two reviews, close four tabs, and eventually buy from the tab you'd forgotten about. Rinse. Repeat.
That script is getting rewritten, fast.
In 2026, a growing number of buyers skip the Google tab-opening ritual entirely. They open ChatGPT, Perplexity, or Google AI Mode, type something like "what's a good sustainable yoga mat under £60 with fast UK shipping?", and get a direct recommendation. With a link. Sometimes, with a buy button built right in.
If your marketplace products aren't showing up in those answers, you're losing buyers you never even knew were looking.
This post breaks down exactly what's happening, why it matters for marketplace founders specifically, and what you can do about it right now, no computer science degree required.
The numbers that should stop you mid-scroll
Let's get the hard data out of the way first, because these numbers are the kind that belong in a board meeting deck.
- AI traffic to US retail websites grew 393% year-over-year in Q1 2026, according to Adobe Digital Insights.
- 810 million people use ChatGPT daily as of early 2026. Product research and shopping is now the fastest-growing query category on the platform — up 89% year-over-year.
- 73% of B2B buyers now use AI tools like ChatGPT and Perplexity as part of their purchase research process (Averi, March 2026 analysis of 680 million citations).
- Shoppers who arrive from AI platforms are 33% less likely to bounce and convert 31% more than visitors from traditional search sources (Adobe Analytics).
- AI search traffic converts at 14.2% compared to Google organic's 2.8% — that's a 5x difference in conversion rate.
So no, this is not hype.
The buyer who lands on your marketplace via a ChatGPT recommendation is already halfway sold before they get there. The AI did the persuading.
For Shipturtle customers, the Performance Marketing add-on is specifically built around this reality of optimising both for traditional Google ranking and for AI-driven search discovery. The marketplaces that get in front of this shift early are the ones that will own their categories in the next two years.
Why this is different for marketplaces (and harder)
Most of the conversation about AI shopping is aimed at single-brand stores. "Make sure your product descriptions are good. Add review schema. Done."
For marketplace founders, the challenge is more layered. You're not managing one product catalogue; you're managing dozens, hundreds, or thousands of vendor catalogues, each with varying levels of quality, completeness, and consistency. And AI doesn't care about your excuses. If a product listing is missing its price, has no reviews, or has inconsistent specs across pages, the AI quietly skips it and recommends something else.
Here's the uncomfortable truth: your marketplace's discoverability in AI search is only as good as your worst vendor's product data.
That's not a problem most single-brand Shopify stores have. It's very much a problem you have.
The platforms you need to know
Understanding which AI platforms are actually driving shopping queries helps you prioritise where to focus. As of mid-2026, the landscape looks like this:
ChatGPT Shopping
ChatGPT crossed 900 million weekly active users in February 2026. OpenAI's shopping feature, relaunched in February 2026 as "Buy it in ChatGPT," now covers over 1 million Shopify merchants, including major brands like Glossier, SKIMS, and Vuori. If your marketplace is built on Shopify, your products are automatically syndicated to ChatGPT via the Shopify Catalog. No opt-in required. The catch: your product data still needs to be structured and complete for ChatGPT to confidently recommend it.
Perplexity
Perplexity has around 30 million users and is growing. It's more research-heavy than ChatGPT; buyers use it to compare options and understand trade-offs before purchasing. Perplexity is particularly effective at surfacing niche or specialist products because it synthesises information from across the web and rewards content-rich, authoritative product pages. Think of it as the buyer who reads the fine print.
Google AI Mode and AI Overviews
Google isn't sitting this one out. AI Overviews now appear on 14% of shopping queries, up 5.6x in just four months. Google's AI Mode pulls from both its Merchant Center feed and on-page schema markup. For marketplace founders, this means your Google Merchant Center data and your on-page product schema need to match exactly. Any mismatch and Google's AI drops you from consideration.
The others
Claude, Microsoft Copilot, and Gemini each hold meaningful shares of AI-referred traffic. The key insight here: ChatGPT's share of AI referrals has dropped from near-monopoly to around 62.6% of B2B AI traffic, with Claude at 18.5% and Gemini at 10.6%. Optimising for just one platform means missing roughly 37% of AI shopping traffic.
Because Shipturtle is Shopify-native, marketplaces built on it automatically inherit Shopify's catalog syndication infrastructure, meaning your products are eligible for ChatGPT, Google AI Mode, and Perplexity discovery without rebuilding your tech stack from scratch. It's one of the quieter advantages of building on the right platform from day one rather than retrofitting discoverability later.
How AI actually decides what to recommend
This is where it gets practical. AI platforms don't browse your marketplace the way a human does. They don't think "oh, nice design" or "I like the vibe of this brand." They read structured data, the machine-readable metadata underneath your product pages, and make decisions based on how complete, consistent, and trustworthy that data is.
Here's what AI systems look for when deciding whether to recommend a product:
1. Structured product data (schema markup)
This is the single most important factor. AI shopping assistants like ChatGPT, Perplexity, and Google AI Mode primarily rely on crawled web content and JSON-LD structured data markup to discover and evaluate products. If your product pages don't have proper Product schema: including name, brand, price, availability, GTIN, and description, you're essentially invisible to the AI.
The good news: Shopify generates basic product schema automatically. The bad news: "basic" often isn't enough. You need a complete schema, and if you're running a multi-vendor marketplace, that means every vendor's product needs a complete schema — not just the ones that bother filling in all the fields.
2. Review signals
AI systems use reviews to assess product quality. Pages with Review and AggregateRating Schema markup sees higher citation rates in AI responses. If your vendor products have no reviews or reviews that aren't marked up, AI has no trust signal to work with and will often recommend a competitor's product that does.
3. Price consistency across channels
When your product feed price disagrees with your on-site price, or your marketplace price doesn't match your Google Merchant Center data, AI treats it as unreliable data and quietly removes you from consideration. Shoppers notice inconsistencies, too, but the AI notices first.
4. Content freshness
Perplexity in particular rewards freshness; it reportedly prefers pages updated every 2-3 days for actively competitive queries. More broadly, content updated within the past two months earns 28% more AI citations than older content, according to Superlines' 2026 AI search research.
5. Answer-ready content
AI platforms don't just want product specs. They want content that directly answers the questions buyers are asking. "Is this sustainable?" "Does this ship to Germany?" "How does this compare to Brand X?" If your product pages and category pages answer these questions clearly and concisely, you're more likely to be cited in AI-generated responses.
Shipturtle's AI Catalog Enrichment directly addresses points 1, 2, and 3, automatically filling missing product attributes, standardising data across vendor listings, and flagging price and SKU inconsistencies before they cost you AI visibility. Think of it as having a full-time catalogue quality manager running silently in the background, except it works across thousands of listings simultaneously and doesn't take lunch breaks.
What marketplace founders should do right now
Enough theory. Here's the practical action list, ordered by impact.
Step 1: Audit your product schema coverage
Check whether your marketplace's product pages are outputting a complete Product schema in JSON-LD format. At a minimum, each product needs:
namedescriptionbrandoffers(price, availability, currency)imageskuorgtinaggregateRating(if reviews exist)
Most Shopify-based marketplaces get the basics automatically, but completeness varies. Run your top product pages through Google's Rich Results Test to see what's actually being output.
Step 2: Educate your vendors on product data quality
This is the part most marketplace operators skip, and it's arguably the most impactful thing you can do. Your vendors don't know that their half-filled product descriptions and missing SKUs are costing them AI visibility. Tell them. Make it part of your vendor onboarding.
A simple brief: "Here's what a well-optimized product listing looks like, and here's why it matters" goes a long way. Some marketplace operators are going further: gating certain features (promoted listings, homepage placement) behind a minimum product data quality score. That's smart.
Step 3: Get on the Shopify Catalogue if you're Shopify-based
If your marketplace runs on Shopify, your products are already eligible for ChatGPT's Shopping feature via the Shopify Catalogue. No opt-in required. But eligibility and visibility are different things; your product data quality determines whether ChatGPT actually recommends you.
For Google AI Mode, opt in through Agentic Storefronts in your Shopify admin. This syncs your catalogue to Google's AI-powered discovery layer.
Step 4: Fix your Google Merchant Center feed
If you're not already running a Google Merchant Center feed, start. If you are, audit it for price consistency and completeness. Every product your vendors list should have accurate, up-to-date pricing that matches the on-site price exactly. Set up automated feed refreshes so the data doesn't go stale.
Step 5: Build review infrastructure
Reviews are a trust signal for AI, not just buyers. If your marketplace doesn't have a structured review system, one that generates Review schema markup, you're leaving AI visibility on the table. Invest in getting more vendor and product reviews, and make sure they're properly marked up in your product schema.
Step 6: Write answer-ready category and buying guide content
AI platforms love content that directly answers questions. Your category pages and blog content are real estate for this. A page titled "Best sustainable yoga mats under £60 with UK shipping" that actually answers that question clearly, with specific product recommendations, comparison points, and delivery details, has a strong chance of being cited in AI shopping responses.
This is what GEO (Generative Engine Optimization) looks like in practice: writing content the way a helpful expert would answer a question, structured so that AI can extract and cite your answer directly. Shipturtle's Performance Marketing add-on handles exactly this, producing content specifically optimized for AI-driven discovery, not just traditional search. And at the product level, Shipturtle's Listing Genie lets you define category-specific AI prompts with custom tone, character limits, and brand guidelines, so every vendor listing reads like it was written by someone who actually knows what AI is looking for, not a vendor who typed three words and called it done. One customer noted the Performance Marketing add-on drove meaningful organic traffic to their platform in a niche industry, which is about as strong a validation as you can get for a brand-new marketplace.

The multi-platform reality
One more thing worth flagging: optimising for ChatGPT alone is no longer enough. ChatGPT's share of AI referral traffic has dropped significantly as Claude, Gemini, and Perplexity have grown. Each platform has slightly different retrieval logic and citation behaviour.
The good news is that the fundamentals work across all platforms: complete product schema, consistent pricing, strong reviews, and answer-ready content will make you more discoverable on all of them. You don't need a separate strategy for each; you need one solid foundation. Shipturtle's Ops Copilot helps here too; it surfaces catalogue inconsistencies, vendor data gaps, and operational issues before they affect your discoverability, so your team is fixing problems proactively rather than discovering them when your AI traffic drops.
Shipturtle helps marketplace founders build, manage, and scale multi-vendor marketplaces on Shopify. With the tools and infrastructure to support everything from vendor onboarding to order management.

What AI won't replace
In the interest of not being alarmist: AI product discovery is powerful, but it's not the whole picture.
Buyers still value brand trust, community, and the kind of social proof that comes from seeing real people use a product. AI can surface your products, but it can't build the emotional connection that turns a one-time buyer into a loyal repeat customer.
What's shifting is the top of the funnel, the discovery moment. And that's exactly where AI is now, making decisions that used to belong to Google's search algorithm. Getting your products in front of AI systems well means you get more buyers at the top of the funnel to then convert through brand experience, great product quality, and exceptional vendor service.
The bottom line
The way buyers discover products is changing underneath your feet, and it's changing fast. AI platforms handled tens of millions of shopping queries every day in 2025, and that number is growing aggressively in 2026. The buyers arriving via those platforms convert better, bounce less, and are further along in their decision before they even reach your site.
For marketplace founders, the challenge is real but manageable: the product data quality you invest in now becomes your competitive moat as AI becomes the default starting point for product discovery. Clean product schema, consistent pricing, structured reviews, and content that answers real questions; these aren't optional extras. They're table stakes for the next era of ecommerce.
The marketplaces that get this right now will have a meaningful head start. The ones who wait will be asking, "Why isn't anyone finding our products?" Two years from now, the answer will be: because the AI didn't know enough about them to recommend them.
