It can show up first as an oddity in the reports. Organic sessions sit about where they were, but orders start arriving from people who landed straight on a product page and never touched the homepage. Then a customer mentions it in chat, almost in passing: an assistant recommended you.

If your first question is which file needs uploading, the answer is less exciting than that: most of this layer is already switched on in your store, and what is left is a different kind of work.

Shopify already wired your catalog into the AI channels

Shopify Catalog is what hands your product data to assistants, and the Help Center is blunt about it: you can't opt out of Shopify Catalog itself. What you can do is stop an individual agentic storefront from reaching your products, through the Shopify Catalog access and Direct checkout settings under Sales channels > Agentic — though both stay locked while Allow Shopify to manage for me is on: with that setting enabled Shopify auto-enrols you in every new agentic channel, and it has to be turned off before you can change either one.

The inclusion requirements are specific: Starter plan or higher, the store out of private mode, the product published to your online store, Hydrogen or Headless channels, with a title, an image, a price above zero, an identifiable URL, no Unlisted status and no hiding from search engines. The other half of the list is administrative: a verified email, two-step authentication, identity and business verification, a low chargeback rate, and Shopify invoices paid on time. Shopify reviews all of it on an ongoing basis.

Cutting a channel off also reaches less far than it sounds. The documentation describes removing Shopify Catalog access for ChatGPT or Microsoft Copilot, and warns that your products might still be displayed through other external discovery and listing methods. Pulling a product out entirely means setting it to Unlisted, which also hides it from your sitemaps, from search engines and from your own store search.

Eligibility turns on who you sell to, not where your store sits

This is the part that most changes the plan for a store in Panama City, Bogotá or Santiago. The general requirements page sets no country requirement at all: it asks for Shopify Catalog eligibility, completed store policies, and agreement to the Agentic Storefronts Supplemental Terms of Service. The geography lives in the individual channels:

  • ChatGPT: you must sell to customers in the United States, but the page states plainly that your store can be based outside it. There is no direct checkout here — shoppers are redirected to your own checkout.
  • Microsoft Copilot: the only requirement is selling to customers in the United States, and this one does have direct checkout. Shopify says neither channel charges fees of its own.
  • Meta: the same customer requirement, plus the Facebook and Instagram sales channel with product syncing turned on in the Product feed section.
  • Google AI Mode and Gemini: requires the store itself to be based in the United States, plus a valid Google Merchant Center account with the products available in it.

Direct checkout is not a dormant switch waiting for you either. On each of the three channels that offer it, Shopify documents it as active by default for eligible stores, and it has to stay active for shoppers to buy there. The exception is the Agentic plan, where it is off by default and you opt in by hand. In every case it is shown only to shoppers based in the United States.

So a store in Panama City selling to US customers is not shut out of direct checkout for sitting outside the US; it is shut out of the Google channel and nothing else. And if you sell only inside your own market, discovery is worth work today even though direct checkout does not reach your shoppers yet.

Shopify already serves agents.md, llms.txt and llms-full.txt

Every Shopify store serves /agents.md by default, and /llms.txt and /llms-full.txt point at that same content unless you add templates of your own. Since the changelog of May 28, 2026 you can customize them with templates/agents.md.liquid, templates/llms.txt.liquid or templates/llms-full.txt.liquid under Online Store > Themes > Edit code. The Liquid context is restricted to request and agents; globals such as shop and collections render blank.

Before commissioning a bespoke llms.txt, two sourced facts. Google's own documentation says you don't need to create new machine readable files, AI text files, or markup to appear in its AI features. And Google's John Mueller, quoted by Search Engine Journal on June 2, 2026, went further:

I don't think anyone knows – it's purely speculative for now (the file has existed for years, yet none of the AI systems use it — what does it mean?)

Writing your own earns its keep when you have context an agent cannot pull from the catalog, such as how to read your size guide — not as a condition for being surfaced. There is one thing worth checking if you are headless: since August 5, 2026, WebMCP tools have been live with nothing to install on every Liquid storefront and on the Hydrogen developer preview, and agent support is limited for now to Chromium-based browsers through an origin trial.

The real work moved to product data quality

The agent often never visits your page; it queries the catalog. The fields AI platforms consider are title, description, images, type, vendor, collections, tags, barcode (ISBN, UPC, GTIN), variants and their option names, and, on the Agentic plan, the external product URL.

Shopify recommends three things outright: use the most specific type or category available — "men's insulated winter boots," not "footwear"; group genuine variants under one parent so an agent reads a single product with options rather than several loose ones; and write the product fields in literal language, with the marketing copy kept out. Copy that persuades a person does not always let an agent confirm a size or a material.

That is where a real conflict shows up, and it has no single answer: the title that sells is not always the title that describes best. When rewriting the page for the agent would make it worse for the person, there is Catalog mapping, under Sales channels > Agentic > Sources, where you choose whether the title, description and category come from a product attribute, a metafield or a metaobject reference.

Organic still brings the most traffic; AI arrives further down the funnel

Shopify's first-quarter figures for 2026, measured across ChatGPT, Perplexity, Google Gemini, Microsoft Copilot, Claude and Grok, show AI-referred sessions growing more than eightfold year over year and AI-referred orders nearly thirteenfold, against organic search up roughly 5%. In the second quarter AI sessions grew 197% and organic grew 12% on a far larger base: organic still referred more sessions than every tracked AI platform combined.

What changes the work is the shape. In the first quarter, 55% of AI-referred sessions started on a product detail page, against 20% of organic ones; in the second quarter the figure was 50%. They convert at nearly 50% higher rates than organic and carry average order values 14% higher, and in spec-led categories conversion runs at roughly double. Your product page stopped being a destination and became the front door.

Where to start this week

  • Open Sales channels > Agentic and read which channels are active, what access each has, and the state of direct checkout. Confirm the administrative eligibility while you are there — verifications and paid invoices count as much as markup.
  • Complete your shipping and return policies, and edit the FAQs in the Knowledge Base app, which is free and available with all Shopify plans. Those are the answers an agent gives when someone asks about your shipping.
  • Check that you are not blocking agents in robots.txt.liquid, bearing in mind that blocking there does not stop Shopify Catalog from sending your data to the channels you have active. Shopify flags that edit as an unsupported customization.
  • If the business is strictly B2B, check what is exposed: Shopify excludes B2B-exclusive products when it can identify them, but a setup built on third-party apps or custom code may not be identified. Products you sell through both channels appear at the D2C price.

None of this is a quarter-long project. It is disciplined data cleanup on something already running. The hard part is not technical. It is deciding how your product gets described when whoever reads it is going to repeat that description to someone who trusts the answer.

Common questions

Can I opt out of Shopify Catalog?

No. Shopify documents that you can't opt out of Shopify Catalog itself. What you can do is cut off an individual agentic storefront under Sales channels > Agentic, using the Shopify Catalog access and Direct checkout settings; the documentation describes doing this for ChatGPT or Microsoft Copilot. Even then, your products might still be displayed through other external discovery and listing methods. Removing a product altogether means setting it to Unlisted, which also hides it from your sitemaps, from search engines and from your own store search.

Do I need to create an llms.txt file on my Shopify store?

You do not need to create one. Every Shopify store serves /agents.md by default, and /llms.txt and /llms-full.txt point at that same content unless you define your own templates; since the changelog of May 28, 2026 you can customize them under Online Store > Themes > Edit code. Google's documentation also says you don't need new machine readable files or markup to appear in its AI features, and John Mueller called the file purely speculative in June 2026. Writing your own makes sense if you want to give an agent context the catalog cannot carry, not as a condition for being surfaced.

Do agentic storefronts work if my store is based in Panama, Mexico or Colombia?

Largely, yes. Shopify's general requirements page sets no country requirement: it asks for Shopify Catalog eligibility, completed policies and agreement to the supplemental terms. What the channels ask for is selling to customers in the United States — that is how ChatGPT, Microsoft Copilot and Meta put it, and the ChatGPT page states that your store can be based outside the United States. The only channel requiring a US-based store is Google AI Mode and Gemini. Where direct checkout exists, Shopify documents it as active by default for eligible stores, and it is shown only to shoppers based in the United States.

If I block AI crawlers in robots.txt, do I stop appearing in assistants?

Not necessarily. Blocking crawlers there does not stop Shopify Catalog from sending your product data to the agentic channels you have active, because access works in two separate layers: network-level bot management, handled by the platform, and robots.txt rules, which are directional and advisory. Shopify also flags editing robots.txt.liquid as an unsupported customization and warns that incorrect use can result in loss of all traffic.
