Free Schema Markup Generator

Schema markup (structured data) is code, usually in JSON-LD, that describes your page to search engines and AI assistants — what is an article, who is the author, what is the price, what are the steps. What it reliably does is remove ambiguity for anything that parses the page. It also keeps you eligible for the rich results Google still supports: Article, Breadcrumb, Local business, Organization, Product and Profile page are all in Google’s current search gallery (read 2026-09-23). FAQ and HowTo are not — HowTo rich results went away in 2023 and Google ended FAQ rich results on 7 May 2026. Treat schema as machine-readability, not as a way to get cited in AI answers.

Paste the entire <script type="application/ld+json"> block anywhere inside your page’s HTML — the <head> is ideal, but the <body> works too. Add it to the specific page the data describes (e.g. the Article markup goes on that article’s page).

The generator outputs clean schema.org JSON-LD in the format Google recommends. After pasting it, confirm it parses with the Schema Markup Validator at validator.schema.org, which covers every schema.org type. Google’s Rich Results Test only covers the types that still have a rich result, so Article, Breadcrumb, Local business, Organization and Product will report there and flag missing recommended fields, while a HowTo block will report nothing — Google retired that rich result in 2023.

Only if those ratings are real and come from genuine reviews. Inventing star ratings to win rich snippets violates Google’s structured-data policies and can trigger a manual action. Leave the rating fields blank unless you have authentic reviews to back them up.

Nobody can promise that, and we will not. No AI engine documents structured data, or the sameAs property, as something it uses to decide what to cite. Google states that structured data is not required for its generative AI features and that there is no special markup to add (AI optimization guide, last updated 2026-07-10, read 2026-09-23). Microsoft is the one operator that claims a benefit, saying schema helps its AI systems read content with more confidence for Copilot and AI answers in Bing (Microsoft Advertising blog, 2025-10-08, read 2026-09-23). OpenAI and Perplexity publish nothing either way, and a May 2026 difference-in-differences study by Ahrefs (an SEO tool vendor) found no citation uplift from adding schema — though every page it measured was already cited heavily, so it says nothing about pages AI has not found yet. What structured data verifiably does is remove ambiguity: it states which organization published the page, who wrote it, when it was updated, what the price is. That is worth having whether or not an engine uses it.
