Hi everyone

SEO used to mean ranking on Google. But with tools like ChatGPT, Gemini, and Claude changing how people search, I’ve been asking myself:

How do we make sure our Shopify stores show up when these models recommend products?

A few things I’m curious about:

  • Do LLMs still use traditional SEO signals like meta titles, schema, and backlinks?

  • Or do they lean more on knowledge graphs, product feeds, or reviews?

  • Has anyone seen their store mentioned by an AI tool yet?

  • Could “LLM SEO” become the next big channel for ecommerce discovery?

Would love to hear if anyone’s experimenting with this or testing ways to get noticed by AI assistants.

Thanks :folded_hands:

Hi @Lyros, LLM like ChatGPT, Gemini, or Claude don’t crawl the web in real-time the same way Google does. Instead, they’re trained on a mix of public data, licensed content, and sometimes third-party integrations.

That means:

:white_check_mark: Traditional SEO signals (titles, schema, backlinks, etc.) still matter for Google and other search engines, and indirectly for LLMs too, because many AI models pull from search engine results or knowledge panels when answering.

:card_index_dividers: Structured data, product feeds, and reviews are becoming more influential. These are easier for AI to understand and may feed into the knowledge graphs or APIs that models tap into.

I’ve seen early experiments where Shopify stores get surfaced in AI-driven shopping recommendations (mainly when products are well-optimized on Google Shopping, marketplaces, or review platforms).

“LLM SEO” is not a formal discipline yet, but positioning your store for AI visibility could become a new growth channel, similar to how “voice search optimization” emerged a few years back.

For now, the best approach seems to be:

  • Keep your traditional SEO fundamentals strong.
  • Use structured data/schema for products.
  • Optimize product feeds for Google Shopping and marketplaces.
  • Encourage and manage customer reviews, these carry weight across multiple platforms.

I think we’ll see more concrete tactics as LLMs integrate deeper with commerce platforms.

Hope this helps :blush:

Hi @Lyros

Optimizing your Shopify store for LLMs like ChatGPT is about making your information clear, structured, and authoritative. Focus on creating high-quality, detailed product descriptions and blog content that directly answer the types of conversational questions customers might ask an AI.

Technically, the most important step is to implement comprehensive structured data, also known as schema markup, for your products, reviews, and FAQs. This provides a clear, machine-readable summary of your content that AI can easily understand and trust.

Finally, build your store’s authority by encouraging genuine customer reviews and creating a logical site structure with internal links between related content. A store that is well-structured and rich with helpful, user-focused information is best positioned to be recommended as a reliable answer by an LLM.

Hope this helps!

Great question, Lyros. I work across AI and ecommerce and here’s what I’m noticing:

  1. Traditional SEO still helps
    Clean site structure, fast loading, clear meta titles, and good backlinks still matter. LLMs read the public web, so these basics make it easier for them to understand your store.

  2. Structured data is key
    Add product schema/JSON-LD, keep your sitemap current, and use product feeds like Google Merchant. Claim your Google Business or brand knowledge panel so your info is accurate in knowledge graphs.

  3. Build trusted signals
    Collect reviews, get mentioned on reputable sites, and publish helpful guides or FAQs. Models like ChatGPT often pull from sources they see as credible.

  4. Check for AI mentions
    Search your brand on tools like Perplexity or ChatGPT with browsing to see if you’re already being cited.

  5. Think “AI Optimization”
    Combine strong SEO, structured data, and brand authority.

    Example: A Shopify coffee brand posts a detailed guide on choosing sustainable coffee, marks it up with schema, and shares it with bloggers. Over time, AI tools start referencing that guide when people ask for sustainable coffee recommendations.

In short: good SEO + structured data + trustworthy content is the best way to show up when AI tools recommend products.

Great question @Lyros, The biggest difference is that LLMs don’t work like search engine crawlers, which index data in real time. Even when LLMs have live search features, they’re not as extensive as search engines. Most LLMs rely on training data that can be outdated. You can even ask them, for example, in ChatGPT: 'What’s the latest you know?

The biggest good news is that many big tech companies are working on protocols that will allow LLMs to browse products and make purchases, as the prediction is that most consumers in the future will be LLMs. So there is a strong chance that your products will automatically become visible to the LLMs.

Good Luck!

Great point, @shivam_kumar — you’re absolutely right that LLMs (Large Language Models) don’t operate like traditional search engines since they don’t index live data in real time. However, as Shopify merchants, it’s already worth preparing your stores for the LLM era of discovery.

Here are a few practical recommendations based on our experience as an E-Commerce & SEO agency:

Use structured data: Make sure your product, pricing, and availability information is properly marked up with schema.org. This not only helps Google but also ensures future LLMs can understand your content contextually.

Write semantically rich content: Product descriptions, FAQs, and metadata should be clear, contextual, and natural — LLMs “understand” meaning and relationships better than traditional keyword crawlers.

Optimize for performance & accessibility: Fast load times and accessible design (WCAG/BfSG compliance) improve both user experience and machine readability, which will matter even more in AI-driven discovery.

Stay ahead of emerging LLM protocols: Keep an eye on upcoming APIs and integrations that may allow LLMs to access product data directly (e.g., through OpenAI, Google Merchant Center, or future Shopify AI tools).

At Muthwerk, we’re already preparing our clients for a future where products need to be readable and understandable not just by humans — but by intelligent systems as well.

Best,

Hi Lyros — great question.

Short version: LLMs still care about traditional SEO signals, but they also add new signals and channels (knowledge graphs, product feeds, reviews, and explicit agent-friendly signals like llms.txt, ect). Here’s how I’d break it down:

1) Do LLMs still use meta titles, schema, backlinks?

Yes — generative engines often surface content that already performs well in search, and they also rely on structured signals that make content easier to cite or extract (JSON-LD/schema, clear metadata, page speed, E-E-A-T). Optimize these fundamentals first because many AI overviews and agent responses still draw from high-authority web sources and passages.

2) Do they lean on knowledge graphs, feeds, and reviews?

Also yes — product feeds, knowledge graph entries (structured org/product data), and review signals help agents recommend products more confidently and with context (price, availability, ratings). Platforms building commerce integrations (e.g., Gemini x Google Shopping, Shopify × OpenAI, etc) show that agent-to-shop pipelines and merchant feeds are emerging as a new channel, although it is still quite early and no significant public data has been released yet.

3) Has anyone seen their store mentioned by an AI tool yet? Could “LLM SEO” become the next big channel for ecommerce discovery?

It’s also worth noting that Shopify’s official collaboration with OpenAI on September 29, 2025 signals that agent-based commerce pathways are being productized, so now is a good time to start experimenting.

The market is still very new, which gives early merchants a real advantage to explore and establish presence before competition grows.

And personally, I believe it’s only a matter of time before ChatGPT and similar AI platforms introduce ad slots or sponsored placements — meaning merchants should prepare for both organic “LLM SEO” and future paid visibility opportunities within AI ecosystems.

We’re actively building for this shift — our Tapita AI SEO & Speed Optimizer app already helps with JSON-LD, meta tags, speed, image optimization and adding LLMs.txt so merchants can publish agent-friendly signals from the Shopify admin.

4) Practical things to test:

  • Add and validate Product related schema (JSON-LD) on product and brand pages

  • Publish llms.txt (rule set for AI agents) — it’s an emerging convention to tell agents what to index or not. You can try our free feature inside the Tapita AI SEO & Speed app that allows merchants to add LLMs.txt for any page.

  • Make content chunkable: each paragraph/FAQ should answer a single question so chunk-level retrieval works.

  • Improve page speed & Core Web Vitals (fast pages are more likely to be fetched/cited)

  • Encourage first-hand reviews, Q&As, and partner mentions so the model sees repeated brand+trait associations across sources.

  • Publish a product feed or merchant data (if the AI/assistant supports commerce endpoints) and monitor agent referrals where possible.

Hope it helps!

Hi @Lyros

While LLM work in a similar way to SEO the major difference is Google ranks pages LLM ranks paragraphs. Think of it as chunking of pages.

What you should cover?

Product Schema (JSON-LD): LLM loves structured data which would tell what you sell, at what price you sell and how does your product rate.

Chunking: LLM will read your page in chunks or paras. So 1 paragraph each containing what you are selling, who are you selling too, why your product is unique. So you could basically add FAQ page on this.

Reviews : LLM need reviews so your funnel and backlinks should have as many reviews of each product as possible.Generic reviews (“great product!”) teach LLMs nothing. Specific reviews (“best waterproof mascara for humid climates”) are what trains the model to recommend you for precise queries.

LLMs.txt: Similar to robots.txt a file that signals to LLM what to index and how to represent your store. Still early but worth adding now before it becomes standard practice.

The Shopify and OpenAI collaboration from 2025 signals agent-based shopping is being productised .Happy to go deeper on any of these if you share your store’s niche.

FoundGPT: llms.txt & AI Score for Shopify

Most of the answers here cover the basics well but the single
biggest thing I see stores miss is robots.txt.

I checked 10 Canadian Shopify stores recently and 9 out of 10
were blocking GPTBot, ClaudeBot, and PerplexityBot without
realizing it. If those crawlers can’t read your site then no
amount of schema or content optimization matters. You’re
invisible at the most basic level.

Go to yourstore.com/robots.txt and look for those bot names
under any Disallow rules. You can edit it in Shopify Admin
under Online Store then Preferences then Edit robots.txt.

After that the highest leverage stuff in order:

  1. Add an llms.txt file (rahular mentioned this above, agree
    its worth doing now). Plain text summary of your business,
    products, and key pages at your site root.

  2. FAQPage schema on product and collection pages using the
    actual questions customers ask before buying. LLMs pull from
    these directly.

  3. Organization schema so AI knows who you are, where you’re
    based, what you sell. Shopify doesn’t generate this by default.

This matters more now than it did when this thread started.
Shopify just announced native purchases inside ChatGPT so
the stores that are AI-readable now will be the ones getting
recommended when that rolls out.

Hey

Just jumping on this, even though it’s an older post, for anyone reading through.

LLMs.txt is a standard currently being developed for exactly this purpose. It’s essentially a plain text version of the key information on your site, all in one place, so AI tools can easily access and understand it. You can read more about it here: https://llmstxt.org/

It’s still fairly complex and evolving quickly, but there are apps (like https://apps.shopify.com/autollm, which I built) that handle everything for you and keep it automatically updated as the standard develops.

19

Been working on this for a while now. Here’s what actually moves the needle:

  1. Product data completeness — LLMs pull from your structured data first. Make sure every product has full JSON-LD markup, complete attributes (ingredients, dimensions, certifications), and natural-language descriptions. Most Shopify stores have bare-minimum default markup.
  2. Third-party mentions matter more than you’d think — 46% of Perplexity’s citations come from Reddit alone. If nobody is talking about your products outside your own site, AI has no third-party signal to work with.
  3. Intent-matched content — Create pages that directly answer the questions people ask AI. “Best protein powder for recovery” needs a comparison guide, not a product page. FAQ content per product category is massive.
  4. Shopify’s Agentic Storefronts — If you’re on Shopify, your catalogue can auto-syndicate to ChatGPT, Gemini, and Copilot. But it only works well if your product data is actually complete and machine-readable.

Quick test: ask ChatGPT to recommend products in your category. If you don’t show up, your data isn’t structured well enough for AI to understand.

@Geoffy the breakdown you shared is the most practical summary in this thread and the 46% Reddit citation stat is the one that should reset how merchants think about this.

It maps directly to the two-lever framework I keep coming back to when auditing stores: roughly 60% of AI visibility comes from external citations (Reddit, blogs, gift guides, review roundups) and 40% from internal store health (schema, product data completeness, llms.txt). Most merchants spend all their time on the internal 40% because it feels controllable, while the external 60% sits untouched because nobody tells them which pages to target.

The practical move on the citation side: run the ChatGPT query for your top 3 product categories and click through to the sources it cites. Those URLs are your outreach list. Getting a single mention on a page that ChatGPT already trusts is worth more than a month of description rewrites. For most Shopify merchants in niche categories, 3 to 5 strong external mentions are enough to start appearing in AI responses.

Your robots.txt point from earlier in the thread is the baseline check that should happen first. No amount of external citations help if the model cannot crawl your store to verify the product exists and confirm price, availability, and attributes. Both layers have to work for the flywheel to start.

The gap most stores miss is between two prompt types.

Brand-aware prompts (“is X good for sensitive skin”, “compare X with Y”) are easier to win. If your product pages have decent descriptions, models cite you when someone types your name.

Discovery prompts (“best natural moisturizer for sensitive skin under $30”) are where most Shopify stores get zero citations. I scanned a natural skincare brand recently that hit 100% on brand-aware prompts and 0% on 16 discovery prompts in the same scan.

The three patterns that closed the gap for the brands winning discovery prompts:

  1. Comparison tables inside product descriptions. Models extract tables verbatim. Prose gets paraphrased and loses attribution.

  2. Third-party content (blog with expert quotes, YouTube demos). Perplexity especially pulls from external sources before the brand’s own site.

  3. Numerical proof points inside copy. “94% of testers reported X” gets quoted. “Deeply nourishing” gets summarized away.

None of those require a brand reposition. All are page-level edits a Shopify-native team can ship in a week.

22

Good question. Traditional SEO still helps but LLMs pull from different places now. Schema markup and backlinks still matter. But they also look at reviews, product feeds, and natural language content.

Shopify already lets you sell inside ChatGPT. So yeah, LLM SEO is becoming a real channel.

I have not seen my store mentioned by an AI yet but some people have. They are getting traffic from ChatGPT answers.
