ChatGPT Can Read Your Store. It Can't Buy From It.

I built a free agent-readiness checker, check your site for free.

It reads up to ten product pages the way an agent does and gives you three answers. Can agents find you, can they understand your products, and can they buy. Each one comes with the single best fix that would help the most products.

Shopify, WooCommerce, BigCommerce or custom. No signup, about a minute. How it works, and what it can't see.

Run it before the 27th. If your store comes back with three green lights, send it to me. I'd like to see one.

Black Friday is Friday 27 November. Cyber Monday is the 30th.

A fair chunk of your shoppers will ask an AI before they ask Google.

In New Zealand, 55% of online shoppers already use AI tools at least some of the time (IAB Australia and Pureprofile). In Australia, 62% expect to use AI for at least one holiday shopping task (Shopify).

So the question store owners keep hearing is: can ChatGPT buy from me?

For most NZ and Australian stores, the honest answer this Black Friday is.

No.

And that's fine.

Buying isn't where you're losing.

Written from the US

Most of what's written about agentic commerce is written from the US. Read it from Auckland and half of it doesn't apply.

Here's what actually reaches a store down here, as of October 2026.

Google AI Mode has been live in New Zealand since August 2025 and Australia since October 2025. It researches and recommends products for shoppers in both.

Checkout inside AI Mode is another story. It covers selected merchants in the US, Canada and Australia, by application (Merchant Center Help).

New Zealand isn't on the list.

Australia got it in June, with Adore Beauty, Bunnings, Kogan, Petbarn and THE ICONIC at launch (Retailbiz).

ChatGPT will research and compare for shoppers here all day. Shopify's ChatGPT channel wants a store that sells to customers in the United States (Shopify Help). OpenAI scaled back Instant Checkout in March anyway (Swell).

Shopify's Agentic Storefronts are on by default. To get into Shopify Catalog, your products have to ship to the US or Canada (Shopify). A store that only ships around New Zealand gets nothing from it yet.

Microsoft's Copilot Checkout is US only.

So the agent finds you, reads you, compares you, then sends the shopper to your site to pay.

Which makes November about two things. Being found, and being understood.

The bouncer

Agents start where search engines start. Your robots.txt, your sitemap, and the HTML your server sends.

Each AI company now runs one bot for search and another for training. Blocking training is a fair call. Blocking search takes you out of the answer.

The four to let in:

• Googlebot. AI Mode and AI Overviews run on normal Google Search. Google-Extended only controls Gemini training and grounding (Google).
• OAI-SearchBot, for ChatGPT search. GPTBot is the training one (OpenAI).
• Claude-SearchBot, for Claude. ClaudeBot is the training one (Anthropic).
• PerplexityBot, for Perplexity (Perplexity).

Let Claude-User in too. It fetches your pages when someone asks Claude a question, and it follows robots.txt.

The other way stores lock themselves out is bot protection. A firewall rule switched on after a scraping scare can challenge every crawler that isn't Googlebot.

Nobody notices, because the site works fine in a browser.

Four socks, no sizes

An agent doesn't look at your product photos and read the vibe.

It reads your structured data, the Product and Offer markup in the page. If a detail isn't in there, the agent guesses, or leaves you out of the comparison.

I ran Allbirds NZ through the checker on 21 October. The basics were all there: NZD prices, stock, brand and a barcode.

No shipping.

No returns policy.

And four versions of the Anytime Ankle Sock, with no size or colour on any of them.

An agent could tell you the price. It couldn't tell you whether your size was in stock.

Allbirds isn't a small operator on a free theme, either.

The basics are name, description, image, a price with a currency, and stock. The bits that go missing:

• A barcode (GTIN) or manufacturer part number. Your own SKU doesn't help an agent match you to the same product somewhere else.
• Size and colour on each variant.
• Shipping cost and delivery time.
• Your returns policy.
• Ratings, if you collect reviews.

Shipping and returns matter more in November than any other month. "Will it arrive before Christmas, and can I send it back?" is exactly what someone asks an agent.

The agent can only answer from what you publish.

Checkout, eventually

An agent can only buy for someone, or send them off to pay, when it knows the price and whether the thing is in stock. That part you control today.

The step after that is a checkout the agent completes itself. Two standards are fighting over it.

Universal Commerce Protocol (UCP) comes from Google and Shopify. A store publishes a profile at /.well-known/ucp that tells agents how to check out.

Agentic Commerce Protocol (ACP) comes from OpenAI and Stripe, and sits behind ChatGPT's checkout.

Shopify stores, including NZ ones like Allbirds, already publish a UCP profile. Ready for when Google opens checkout here.

It doesn't mean an agent will check out on an NZ store this November.

If you're in Australia and sell at volume, fill in the Merchant Center interest form. Everyone else, get the price and stock right, and keep the path from an agent's answer to your checkout short.

The afternoon list

In order, for most NZ and Australian stores:

1. Check your robots.txt and bot protection let the four search crawlers and Claude-User in.
2. Publish shipping details and a returns policy in your product data. On Shopify, a structured data app that handles shipping and returns will do it. Otherwise it's a template change.
3. Add GTINs. If your products have barcodes, they belong in the feed and on the page.
4. Label variants with size and colour.
5. Make sure the sale price and stock on the page match your Google feed. When the page, the feed and the structured data disagree, agents drop you or quote the wrong price.

None of this is a re-platform. Most of it is an afternoon with whoever looks after your theme.

So What.

I built a free agent-readiness checker that does this from a URL.

It reads up to ten product pages the way an agent does and gives you three answers. Can agents find you, can they understand your products, and can they buy. Each one comes with the single fix that would help the most products.

Shopify, WooCommerce, BigCommerce or custom. No signup, about a minute. How it works, and what it can't see.

Run it before the 27th. If your store comes back with three green lights, send it to me. I'd like to see one.
