Shoppers are asking ChatGPT what to buy. Your store is not in the answer.
ChatGPT, Perplexity, Google AI Overviews, and Gemini all recommend real products now. Most Shopify stores never show up. Usually the reason is stupid: a blocked crawler, a feed the AI cannot parse, or a missing schema tag.
This PDF is the exact process I use to get stores listed. Free. Grab it below.
- The robots.txt and Cloudflare settings each AI actually needs
- The product feed spec ChatGPT and Perplexity parse (Shopify defaults do not cut it)
- Instant Checkout, who is eligible, and how the application really works
- How to make reviews and ratings appear in AI shopping results
- How to track AI traffic in GA4 and Shopify

Which platforms this covers
The tactical checklist is ChatGPT-first because it's the biggest shopping channel. Most of the same fixes apply across all four.
The primary target. Roughly half of AI shopping traffic. Instant Checkout live via Stripe + ACP.
Pulls product info from your feed. Shopping mode has been live and growing since 2025.
Increasingly surfaces product results. Uses your Merchant Center feed plus schema on-page.
Google's consumer AI. Cites products from indexed pages. Same schema unlocks visibility.
Why listen to me on this
I'm Nikhil. I run e-commerce operations for a US Shopify brand full-time. Not an agency guy. Not an OpenAI reseller. I wrote the post on Shopify's llms.txt rollout. This checklist is what I did on my own store and my clients. Not a repackaged OpenAI blog post.
What's inside
Six sections. You can work through it in an afternoon. No theory, no filler.
The crawler check
The exact robots.txt lines each AI needs (OAI-SearchBot, GPTBot, PerplexityBot, GoogleOther), how to verify Cloudflare isn't silently blocking them, and how to prove ChatGPT can reach your product pages today.
A product feed AI can actually parse
The Shopify feed spec that works with ChatGPT Shopping and Perplexity (JSON-LD Product schema, GTINs, price, availability, image URLs). What breaks the feed and why Shopify's default markup is not enough.
Instant Checkout, without guessing
Who's eligible right now, how the Stripe + Agentic Commerce Protocol integration actually works, and the direct application link to OpenAI. Not a walkthrough of what OpenAI's docs already say — the stuff they leave out.
Reviews that show inside AI answers
Why your Judge.me or Yotpo widget doesn't automatically get pulled into ChatGPT or Perplexity, and the schema.org changes you need so ratings and review counts appear in AI shopping results.
Tracking that survives AI traffic
The UTM patterns OpenAI and Perplexity use on outbound clicks, how to build a GA4 dimension for AI traffic, and the Shopify Analytics gotcha that hides your AI-attributed revenue.
The five silent killers
Out-of-stock listings that keep serving, generic titles that get de-prioritised, missing GTIN penalties, the Cloudflare bot-block that hides you completely, and a fifth one nobody talks about.
Straight from the PDF
Real excerpts, not a mockup. This is the level of detail inside.
The #1 hidden culprit
If you're on Cloudflare, the "Block AI bots" setting can silently return 403 to OAI-SearchBot even when your robots.txt looks perfect. Check Security → Bots and make sure AI-bot blocking is OFF for your domain.

Track what ChatGPT actually sends
ChatGPT appends utm_source=chatgpt.com to outbound links. Build a GA4 segment on that source and track sessions, add-to-carts, and revenue from ChatGPT separately. Set the baseline before you optimize, or you cannot tell which change moved the needle.
The five silent killers
Out-of-stock listings that keep serving. Weak, vague product titles the AI cannot match to a query. A feed that never refreshes so prices quietly go stale. Reviews trapped in a widget the crawler cannot read. And the one nobody talks about: the silent AI-bot block that

Two of my existing pieces on AI shopping. If you like them, the checklist is the tactical distillation.
From my post on Shopify's agentic commerce rollout
"Every Shopify store now has a llms.txt file by default. Most operators don't know it exists. That file is the first thing ChatGPT reads when it tries to figure out what your store sells — and by default, it points at things Shopify chose, not what you'd choose."Read the full post →
Common questions
Is this actually free?
Who is this for?
Does the checklist cover all four platforms in detail?
Does this work if I'm not on Shopify?
Is AI shopping even a real channel yet?
Prefer someone to just do it?
If reading a checklist and implementing it yourself is not your thing, I audit stores end-to-end and give you a specific plan.
