How AI shopping assistants pick products, and how to get your Shopify products cited

How do AI shopping assistants choose products?

No AI company publishes a complete ranking formula, so treat any precise “ranking factor” list with caution. What is publicly known is the broad pipeline: the assistant interprets the shopper’s request, retrieves candidate pages and product data from a search index or merchant feeds, and writes an answer that summarizes and cites the sources it found most relevant and trustworthy. Your job is to be retrievable, understandable and credible at each step.

Which AI assistants recommend products today?

• ChatGPT shows product results with images, prices and links for shopping queries. OpenAI has said these results are selected independently and are not ads. Its search uses OpenAI’s crawler, OAI-SearchBot, alongside third-party search providers.
• Perplexity answers shopping questions with cited sources and product cards, and uses its own crawler, PerplexityBot.
• Google AI Overviews and AI Mode draw on Google’s search index and its Shopping Graph, which is fed in part by Google Merchant Center data.
• Microsoft Copilot relies on Bing’s index.

Shopify has also announced integrations that expose merchant catalogs to AI assistants, including agent-driven checkout features. Availability and eligibility change quickly, so check Shopify’s and each assistant’s current announcements rather than relying on any single article, including this one.

How do I make my Shopify products retrievable?

1. Allow the search crawlers. Make sure robots.txt does not block OAI-SearchBot, PerplexityBot, Googlebot or Bingbot. Blocking training crawlers such as GPTBot is a separate decision that does not remove you from ChatGPT search.
2. Get indexed in Bing as well as Google. Verify Bing Webmaster Tools and submit your sitemap; several assistants depend on Bing’s index.
3. Connect Google Merchant Center through the Google & YouTube channel so your products enter Google’s Shopping data.
4. Keep products available and accurate. Out-of-stock or mispriced items are poor candidates for a recommendation.

How do I make products easy for AI to understand?

1. Lead with a plain statement. The first sentence of the description should say what the product is, who it is for and its key fact, for example “A lightweight merino crew sweater for travel and layering, machine washable.”
2. Put specs in text. Materials, dimensions, compatibility and ingredients belong in HTML, not only in images.
3. Answer comparison questions. Shoppers ask assistants “best X for Y”. A line such as “Best for sensitive skin; not suitable for…” maps directly to those requests.
4. Add a product FAQ with FAQPage markup. In our 2026 study, 89% of top Shopify product pages had none.
5. Check your Product schema so price, availability, brand and GTIN are machine-readable. See Shopify product schema.

How do I earn trust and citations?

• Consistency across sources. The same price, specs and claims on your page, in your feed, on marketplaces and in your social posts.
• Genuine reviews displayed on product pages. Never buy, invent or selectively edit reviews.
• Independent mentions. Coverage in comparison articles, forums, gift guides and review sites gives assistants something to corroborate your claims with.
• Clear brand facts. An About page and consistent business details help assistants identify who you are.

What should I avoid?

• Hidden text or keyword lists aimed at AI systems; they add nothing a model can trust.
• Superlatives without evidence (“the best in the world”), which assistants rarely repeat.
• Fabricated statistics or testimonials, which can damage trust with shoppers and platforms.
• Treating llms.txt as a shortcut. It is a cheap extra, not a substitute for crawlable product pages.

How do I check whether AI assistants mention my products?

1. Write ten to twenty questions a real shopper would ask, such as “best lightweight merino sweater for travel”.
2. Ask them in ChatGPT, Perplexity and Google each month, signed out where possible, and note whether your brand or products appear and which sources are cited.
3. Look at the cited pages: they show what kind of content the assistant trusts for that question.
4. Improve your pages and earn coverage where competitors are cited and you are not.

Is optimizing for AI different from regular SEO?

Mostly not. Crawlable pages, clear titles, structured descriptions, accurate structured data and genuine reputation help in Google and in AI assistants alike. The difference is emphasis: assistants reward pages that state facts plainly and answer comparison questions directly, because they need sentences they can quote with confidence.

What are the key facts to remember?

• OAI-SearchBot powers ChatGPT search; GPTBot collects training data.
• Perplexity uses PerplexityBot to crawl pages.
• Google’s AI shopping experiences draw on the Shopping Graph and Merchant Center data.
• Microsoft Copilot relies on Bing’s index.
• No AI company publishes a full product ranking formula.
