AI trust signals are the facts on your own store that an AI assistant can verify before it names you. They are your reviews, your written policies, one consistent business identity and product facts that agree with the page. A buyer checks the same things in a few seconds. Each signal has to be visible to a person and readable by a machine.
This guide covers what your own website says about you. What other websites say about you is a different question, and our guide on why AI recommends your competitors answers it. Our Wikidata guide covers how a brand earns a place in a public knowledge base.
Which trust signals does an AI assistant read on a store?
Six signals do most of the work. The table shows what the buyer sees for each one and what a machine reads.
| Signal | What the buyer sees | What a machine reads |
|---|---|---|
| Reviews | Names, dates and a spread of ratings | Review and AggregateRating markup that matches the reviews visible on the page |
| Policies | Shipping and return pages that answer in a line or two | Policy pages it can reach, and a MerchantReturnPolicy where one is marked up |
| Business identity | A company name, a contact route and the people behind it | One Organization block with the same name, logo and profile links everywhere |
| Product facts | Price, stock and size on the page | Product and Offer markup that agrees with the page |
| About and press | A real story and coverage a buyer can click | An About page linked from the homepage, with links out to the coverage |
| Author | A named person on guides and blog posts | An article author who is a person, linked to the About page |
Authority Signal, the layer of our score that checks identity and trust markers, was failed by 68% of the 216 Shopify storefronts in our June 2026 study. Most of those stores had reviews and policies. The machine could not read them cleanly, or the identity changed from page to page.
Why do reviews only count when the page shows them?
Google's review snippet guidelines say the review content you mark up must be readily available to users from the marked up page. A star rating that lives only in the code, with no reviews a shopper can see, breaks that rule. It also gives an assistant a number it cannot check against anything.
The same guidelines cover reviews a business controls about itself. Those cannot earn the star feature on pages that use LocalBusiness or Organization markup. Put review markup on product pages, where it describes the product, and keep it off your homepage Organization block. Our guide on collecting reviews that AI trusts covers how to gather them.
How do I set up the six signals on Shopify?
Work through these steps in your Shopify admin, in this order.
- Go to Settings > Policies. In the Written policies section, open the Return policy and turn off Use automated policy if it is on. Write the real terms in two or three plain sentences, then do the same for the Shipping policy. Click Save.
- Go to Content > Menus and open the footer menu. Make sure it links to both policy pages and to your About and Contact pages.
- Go to Settings > Store details and check that the store name is the exact business name you use on every profile and marketplace.
- Open your homepage in a browser, right click, choose View page source and search for "Organization". You want exactly one block. If you find two, our guide on duplicate Organization markup shows which one to remove.
- Open a product page that has reviews and search the source for "aggregateRating". The rating and the review count in the code should equal the numbers a shopper sees above the reviews.
- Open the same product page and compare the price and availability in the Offer markup with the price and stock on the page.
- Go to Content > Blog posts and open your most read guide. In the panel on the right of the post editor, choose the real writer from the Author menu.
A badge from an app can reassure a shopper, but a machine sees only the image, so write the promise behind it in plain text as well.
Which gaps does a leather goods brand with 300 reviews still have?
A small leather goods brand on Shopify sells 40 products and has about 300 reviews, collected through a review app. The review stars show on every product page, and the store looks reliable to a person.
A scan of that store shows three gaps. The review app prints an AggregateRating on the homepage for the whole business, which Google's guidelines say is not eligible for stars. The return terms say "30 days" on the policy page and "14 days" in a product description written two years ago. The theme and an SEO app each print an Organization block, and one of them has an old logo.
The owner moves the rating to the product pages only and rewrites the old description to say 30 days. The SEO app's Organization block is switched off, so one block remains. The store looks exactly the same to a shopper, and the rating, the return window and the logo now agree everywhere an assistant reads them.
Do trust badges and seals help with AI?
A written shipping promise, a return policy in plain text and a phone number in the footer are facts it can read and compare. If a badge makes a claim, such as free returns, write that claim in the text as well. Our guide on putting claims in fields, not prose shows how to store selling points as data.

Questions owners ask
Which trust signal matters most to an AI assistant?
The reviews that help most are the ones a shopper can see on the page and that the markup describes exactly. They give both the buyer and the assistant evidence from real customers. A rating that exists only in the code gives a machine nothing it can confirm.
Should my homepage show a star rating for the whole store?
Keep a store wide rating out of your Organization markup, as Google's review snippet guidelines require. A business that controls the reviews about itself is not eligible for stars on LocalBusiness or Organization pages. Keep review markup on product pages, where it describes the product.
Do I need return policy markup on Shopify?
Start with the written policy under Settings > Policies, since that is the page a buyer and a crawler both read. Google says a store wide return policy can also be marked up with MerchantReturnPolicy under Organization. You can set it in Merchant Center instead, and that setting takes precedence.
Are trust badges useless?
A badge can reassure a person, but a machine sees only an image. Write the promise behind the badge in plain text on the page, such as the return window. An assistant can read that.
