How LLMs and Structured Feeds Are Rewriting Ecommerce Discovery
Ecommerce SEO is changing fast. For years, the game was about optimising your website, content, and links. Now, large language models (LLMs) such as ChatGPT are reshaping how people discover and buy products online.
At We are Chain, we help ecommerce owners stay ahead of these shifts. The latest development, OpenAI’s Agentic Commerce Protocol (ACP), is set to redefine how your products appear, rank, and sell inside AI-driven conversations.
This is where AISEO (AI-powered SEO) and Generative Engine Optimisation (GEO) come together – helping your brand be found naturally inside tools like ChatGPT.
What’s Happening: The Rise of Conversational Commerce
OpenAI has launched ACP in partnership with Stripe, allowing users to purchase products directly through ChatGPT.

For e-commerce brands, this is not just another sales channel. It changes the way visibility and trust work online. ChatGPT now relies on structured product feeds supplied by merchants to decide which products appear in conversations.
Price, availability, product details, and brand data all come directly from your feed, making it the most important source of truth about your business.
In short, your feed is no longer a technical file hidden in the background – it is the voice of your brand inside ChatGPT.
How the Rules Are Changing
1. Completeness and Freshness Are Essential
If your product feed is missing data or your stock and pricing are out of date, you will not appear. The ACP specification allows feed updates as often as every 15 minutes.

At Chain, we audit your product feeds to spot gaps, missing variants, and outdated information, then automate updates to keep your listings accurate and competitive.
2. Optional Fields Create Competitive Advantage
OpenAI’s specification includes optional attributes such as:
- Product reviews and ratings
- Rich media (videos and 3D models)
- Performance data (popularity score and return rate)
- Regional pricing and variant logic
These fields make your data more complete and increase your chances of being recommended in a ChatGPT conversation.

We help you plan, gather, and integrate this information so your feed reflects what shoppers actually ask for in conversation.
3. The Feed Is Now a Marketing Asset
Traditionally, feeds were a developer’s responsibility. Under GEO, they are a marketing tool. Your product data should answer the same questions a customer might ask ChatGPT: “Do you have this in navy?” or “Is this available near me?”
At We are Chain, we work with both your technical and marketing teams to make sure your product naming, variant structure, and descriptions all align with how people actually search and speak.
4. Content Still Matters
Even as ChatGPT consumes structured data, your broader content remains essential. Guides, blogs, and FAQs all shape how your brand is understood and referenced.
Our AISEO approach builds this connection between your product data and your content strategy, using AI tools to align product feeds with your keyword and topic clusters.
5. Early Adopters Will Benefit
ACP and ChatGPT Shopping are still developing, but early adopters are already gaining valuable insight and visibility.

We can help you assess whether your ecommerce platform can integrate now (Shopify, WooCommerce, or a custom setup) and build a plan for when it does.

Why It Matters
- ChatGPT already reaches hundreds of millions of users every week.
- ACP turns it into a shopping assistant as well as a search tool.
- Your product feed is now the foundation of visibility and trust.
Traditional SEO is still vital, but it’s now part of a wider AI-driven ecosystem. The winners will be those who combine structured data precision with creative content and strong brand signals.
Final Thoughts
This is the next big leap in ecommerce. Generative AI will not replace your brand, but it will change how people find and choose you.
At We are Chain, we’re helping ecommerce businesses turn these shifts into an advantage through smarter feeds, better data, and AI-enhanced SEO strategies that future-proof your visibility.
If you’d like to talk about what this could mean for your store, we’d be delighted to show you where to start.
What is an LLM?
It’s the technology behind tools like ChatGPT. LLMs process natural language, understand questions, and generate human-like responses. In ecommerce, they’re changing how people search for and buy products by having conversations rather than typing traditional search queries.
What is ACP?
It allows ChatGPT to connect directly with online stores, read structured product data (feeds), and even process purchases using tools like Stripe’s Instant Checkout. For merchants, ACP turns ChatGPT into a live shopping assistant that can recommend and sell your products inside a chat.
What is GEO?
Think of it as the next evolution of SEO. Instead of optimising web pages for Google’s search results, GEO focuses on how AI tools like ChatGPT generate answers. The goal is to make your brand or products appear naturally inside those generated responses.
What is AISEO?
It’s our way of combining traditional SEO with AI tools to optimise both content and structured data. At Chain, we use AISEO to ensure your product feeds, content, and messaging all speak the same language as AI systems like ChatGPT, helping you rank higher and convert better in the age of conversational search.
What is a Structured Feed?
ACP uses these feeds as its main data source, meaning your feed now plays a crucial role in how products are discovered in ChatGPT.
What is the Difference Between GEO and SEO?
GEO, on the other hand, focuses on visibility within AI-generated answers. Instead of trying to appear on “Page 1,” you’re trying to appear in a conversation where the AI recommends your brand or product as part of its response.
