AI commerce có gì thay đổi — và bạn nên làm gì.

The AI crawlers have split into training bots and search bots, controlled separately in robots.txt. OpenAI runs GPTBot for training but OAI-SearchBot for its answers; Anthropic runs ClaudeBot for training and Claude-SearchBot for search. The blanket "block all AI" robots.txt that spread in 2023 now quietly blocks the exact bots that would cite your product and comparison pages in an AI answer.

You can keep your content out of model training and still be eligible to get cited, but only if you let the search bots in. Roughly a quarter of ecommerce sites are accidentally blocking these at the CDN and don't know it. If the citation bot can't reach your page, you're not in the answer, full stop.

Read your robots.txt and your CDN bot rules for OAI-SearchBot, Claude-SearchBot, PerplexityBot and Google-Extended. If any are blocked, that's why AI isn't naming you. Our field guide walks the exact lines: luma-e.com/blog/ai-search-crawlers-robots-txt-ecommerce-2026

Shopify's Winter '26 release turned on Storefront MCP for Plus stores. General-purpose agents like Claude and ChatGPT can now search your catalog, check inventory and build a cart straight through it, with no app to install. Its Catalog feature syndicates one product listing out to every AI partner automatically. Shopify says AI-driven orders on its stores rose almost 13 times year over year.

The agent reads your live product record, not a marketing page. Whatever sits in the variant, the inventory field and the metafields is what it uses to answer and to build the cart. A gap there, like a missing size or a wrong stock count, becomes the agent's answer.

If you're on Shopify Plus, assume an agent is already reading you. Pull one product through the lens of "what would an agent see" and fix the field that's blank or wrong before it gets quoted.

Perplexity opened a free Merchant Program: connect your product feed and your items show up in its AI shopping answers for around 45 million users. Pro subscribers get "Buy with Pro", a one-click checkout where Perplexity, not the merchant, pays for the free shipping. No listing fee, no commission, which undercuts ChatGPT's 4% agentic-commerce cut.

A clean, current feed is the whole entry ticket. If your price, availability and variants are right, you're eligible to be the recommended product for free. If they're stale, you're either invisible or Perplexity quotes a wrong number to a buyer who's one click from paying.

Check whether your product feed is actually reaching Perplexity, then open one SKU's feed entry against the live store. Free to join means the only thing between you and the answer is your own data quality.

OpenAI shipped the Agentic Commerce Protocol with Stripe and opened it as a public spec. ChatGPT surfaces products, and for some merchants transacts them, straight from a structured feed instead of a crawl of your homepage. Big-box names like Target and Sephora wired it up so they show inside the chat.

Whatever your product record states in clean structured form is what an agent quotes and ranks on: price, stock, the variant, the answer to a question a buyer actually types. If that lives in description prose or a spec PDF, the agent hedges or picks the store that said it plainly.

Open one SKU in ChatGPT and ask for its price, its stock, and one spec buyers keep asking about. If the answer's vague or disagrees with your admin, the fix is your structured data, not your copy.

Google rolled out agentic-commerce tooling plus new Merchant Center attributes built for conversational discovery. Some answer common product questions directly, others flag a compatible accessory or a substitute. Feed freshness now feeds AI Mode and Gemini answers, so a stale price or a wrong availability value shows up in what the assistant tells a shopper.

Your feed used to be an ads input. It's an answer input now. A feed carrying last week's price, or an availability that's already wrong, gets read back to shoppers at scale. Wider reach, wider wrong.

Pick one SKU that changes stock during the day. Check its price and availability in the feed against the live store right now. If they disagree, move that SKU to real-time push (Content API) before touching anything else.
