Does adding schema markup improve your ranking?

Not directly. Google describes structured data as a way to help it understand a page and to make that page eligible for richer search results, not as something that lifts where it ranks. It says no special markup is needed for its AI features. Bing is warmer about markup and AI answers, but still says it guarantees nothing. OpenAI, Anthropic and Perplexity say nothing about it. It is still worth having, for reasons that are narrower than the claim.

This is part of our series checking what small businesses are told about marketing, where every claim is tested against what the company running the system publishes.

What schema markup is

Schema markup, or structured data, is code on a page that labels what the page contains: this is a business, this is its logo, this is a product and its price, this is an event and its date. Most of it uses the shared schema.org vocabulary. Google calls it "explicit clues about the meaning of a page" (Google, introduction to structured data, updated 10 December 2025).

Visitors do not see it. Search engines and other software read it.

What Google says it does

Google gives two uses. It uses structured data "to understand the content of the page, as well as to gather information about the web and the world in general", and it uses it to show a page as a rich result: a listing with extra detail such as a price, a date, breadcrumbs or review stars (Google, introduction to structured data). Google's SEO starter guide puts it the same way: valid structured data "makes your pages eligible for many special features in Google Search results, including review stars, carousels, and more" (Google, SEO starter guide).

The word that matters is eligible. Google's structured data guidelines say it "does not guarantee that your structured data will show up in search results, even if your page is marked up correctly", because markup "enables a feature to be present, it does not guarantee that it will be present" (Google, general structured data guidelines, updated 10 July 2026).

What Google does not say it does

Google does not describe structured data as a ranking signal anywhere in the documentation we read. Its guide to its more notable ranking systems does not mention it (Google, a guide to Google Search ranking systems).

The clearest statement is about what happens when markup breaks the rules. A structured data manual action "means that a page loses eligibility for appearance as a rich result; it doesn't affect how the page ranks in Google web search" (Google, general structured data guidelines). If the penalty for bad markup leaves ranking untouched, markup is not what sets the ranking.

A rich result can still earn more clicks at the same position, because it takes up more space and tells the searcher more. Google's own introduction cites case studies from four very large sites that added structured data: two measured higher click-through rates, one more visits and one more time spent on its pages (Google, introduction to structured data). They show what rich results did for those sites, not that yours will appear.

What Google says about schema and AI search

Google is direct about this. Its page on AI features says: "You don't need to create new machine readable files, AI text files, or markup to appear in these features. There's also no special schema.org structured data that you need to add" (Google, AI features and your website, updated 10 December 2025).

Its guide to generative AI features lists "Overfocusing on structured data" among the things site owners can ignore: "Structured data isn't required for generative AI search, and there's no special schema.org markup you need to add." The same sentence goes on to say "it's a good idea to continue using it as part of your overall SEO strategy, as it helps with being eligible for rich results on Google Search" (Google's guide to generative AI features in Search, updated 10 July 2026).

What Google does ask for its AI features is ordinary: content available as text, structured data that "matches the visible text on the page", and Merchant Center and Business Profile information kept up to date (Google, AI features and your website). For a local business, a complete Google Business Profile is the part of that list most likely to matter.

What Bing says, and where it goes further

Of the two big search engines, Bing is the one that connects markup to AI answers, and it does so carefully. Its webmaster guidelines say: "Structured data may support clearer grounding but does not guarantee visibility or grounding traffic. Markup must accurately reflect visible content" (Bing Webmaster Guidelines, section 14). Grounding, in the words of Bing's search blog, is "the system that connects AI to current, authoritative information".

Bing's blog is more enthusiastic. A November 2025 post says that "Structured content, like schema-marked product pages, FAQs, and comparison tables, helps AI systems interpret and summarize your content more effectively", and that this "increases the chances of your being cited" (Bing Webmaster blog, 20 November 2025). A May 2025 post on product pages recommends schema.org Product markup alongside IndexNow, because "IndexNow tells search engines that something has changed, while structured data tells them what has changed" (Bing Webmaster blog, 19 May 2025).

Read together, Bing says markup may help its systems understand a page and cite it, and its formal guidelines stop short of saying it will. Microsoft also says its grounding "powers nearly every major AI assistant in the market" (Bing Search blog, February 2026). That is Microsoft's own claim about its reach, and it does not say which assistants, or whether any of them read markup. If you want to be found through Bing, our guide to getting your business on Bing covers the basics, and Bing's AI Performance report shows where Copilot cites you.

What the assistant companies do not say

This is the part most schema advice leaves out. OpenAI, Anthropic and Perplexity each publish documentation for site owners, and none of it mentions schema.org markup.

• OpenAI. Its crawler page explains how to let OAI-SearchBot in so a site can appear in ChatGPT search, and says nothing about markup (OpenAI, overview of OpenAI crawlers). Its publisher FAQ names one kind of markup: ARIA labels, the accessibility attributes that help ChatGPT's agent in its Atlas browser "recognize what each element does and interact with your site more accurately" (OpenAI publisher FAQ). That is about an agent using a site, not about which businesses ChatGPT names.
• OpenAI shopping. ChatGPT considers "Structured metadata from first-party and third-party providers (e.g., price, product description)" when choosing products, and merchants can apply to send OpenAI a product feed (OpenAI, shopping with ChatGPT search). OpenAI describes feeds and data providers. It does not say whether markup on your own pages is one of those sources.
• Anthropic. Its crawler page explains ClaudeBot, Claude-User and Claude-SearchBot and how to block each one. It does not mention markup (Anthropic, does Anthropic crawl data from the web).
• Perplexity. Its crawler page explains PerplexityBot and Perplexity-User, and how to allow them through a firewall. It does not mention markup (Perplexity crawlers).

So anyone who says schema will get your business recommended by ChatGPT, Claude or Perplexity is saying something those companies have not said. They may be guessing from how the systems work, or from their own tests, but the evidence here is thin: none of the companies has published anything that supports it or rules it out. Our piece on paying to be recommended by ChatGPT looks at what these companies do say about how businesses get named.

What has stopped working

Some schema advice is simply out of date, because Google has retired the results it used to produce. Google records each change on its documentation updates page (Google Search Central documentation updates):

• FAQ results. The FAQ rich result "will no longer appear in Google Search starting May 7, 2026", and Google removed the documentation on 15 June 2026.
• How-to results. Google removed the how-to documentation on 14 September 2023, as the result was "no longer shown in search results".
• Several specialist types. In June 2025 Google began phasing out book actions, course info, estimated salary, ClaimReview, learning video, special announcement and vehicle listing results, "as part of our ongoing efforts to simplify the Google Search results page". It later kept book actions.

FAQ markup does nothing on Google now. It is not harmful if the questions and answers are really on the page, but adding an FAQ section to carry markup has no Google payoff left.

Why it is still worth having

The honest case for schema is smaller than "it will improve your ranking", and it is still a good case.

• Rich results that still exist. Google still supports rich results for, among others, articles, breadcrumbs, events, products, job postings, local business details and organisation details (Google, structured data markup that Google Search supports). If you sell products, run events or publish articles, eligibility for those is worth having.
• Your organisation's details. Google says Organization markup, covering your logo, legal name and contact details, "can show up in knowledge panels and other visual elements" (Google, structured data markup that Google Search supports).
• Bing. Bing's guidelines say markup "may support clearer grounding" in its AI answers, though they guarantee nothing (Bing Webmaster Guidelines, section 14).
• It can be cheap. Google notes that a content management system may have a search settings page, or a plugin, for adding structured data (Google, introduction to structured data), so on many small sites it is a setting to check rather than a project.

Two rules come with it. Markup must describe what is visible on the page: Google says not to add structured data "about information that is not visible to the user, even if the information is accurate" (Google, introduction to structured data), and Bing says the same. And accuracy beats volume: Google says "it is more important to supply fewer but complete and accurate recommended properties" than every possible property filled in badly (Google, introduction to structured data).

One common mistake is worth naming. Google says pages about a business that use LocalBusiness or Organization markup, where the business controls the reviews about itself, "are ineligible for star review feature" (Google, review snippets). Review stars on your own homepage will not show.

How to tell whether it is working for you

Google suggests its own test rather than a promise. Take some pages without structured data that have several months of Search Console data, add valid markup, confirm Google has found it with the URL Inspection tool, then compare their performance in the Performance report over the following months (Google, introduction to structured data). Google adds that this "can be a little tricky, since page views can vary for a single page for various reasons".

In Search Console, the rich result reports show which pages have valid markup and any errors (Google, introduction to structured data). If a report shows errors, fix them: broken markup is the one way structured data can cost you something, by losing rich result eligibility. Our SEO audit checklist includes this check.

Questions to ask anyone selling schema work

• Which rich result will each piece of markup make my pages eligible for, and does Google still show it?
• Does every property describe something a visitor can see on the page?
• Are you adding FAQ sections or review stars? (Google no longer shows the first, and will not show the second for a business's own reviews.)
• If you say it will help with AI answers, which company's documentation says so?
• How will we measure the effect, and over what period?

Our interest

We do SEO work, and structured data is part of it. We describe it the way this piece does: as accurate markup that can make pages eligible for rich results, never as a ranking lever or a way to be recommended by an assistant. If you have been told your site needs schema to rank, ask us for a second opinion.

Where the evidence is thin

• OpenAI, Anthropic and Perplexity publish nothing on whether schema markup affects which businesses their assistants name. Claims either way are not backed by the companies themselves.
• OpenAI says ChatGPT shopping uses structured product metadata from providers and merchant feeds, but not whether markup on a merchant's own pages is one of those sources.
• Microsoft says its grounding powers "nearly every major AI assistant", but does not name them or say whether any of them use markup.

The verdict

False, as a ranking claim. Google describes structured data as a way to become eligible for rich results, says a structured data penalty does not touch ranking, and says no special markup is needed for its AI features. Bing says markup may help its AI answers and guarantees nothing, and the AI companies say nothing about it. Accurate markup is still worth having for the rich results Google still shows. It is not a ranking lever, and nobody who runs an assistant says it will get you recommended.
