}Three steps, not a single line of code to write.
- 01
Enter a page URL
An article, a product page, a service page or your homepage, as long as it's public. The generator fetches the HTML exactly as your server sends it, then reads the title, meta description, headings, the opening text and any markup that's already there.
- 02
The generator identifies the page
It works out which of fourteen page profiles fits (article, product, FAQ, how-to, event, local business and more) and lists the schema types already on the page. You see the type it picked and the reason behind it, so you can push back if it's wrong.
- 03
You get the code
A single JSON-LD block that brings together two to six types suited to the page, each with an explanation and an impact rating. Copy the full script tag or download the file, then test the code before it goes live.
What is schema markup, and why does it matter for AI answers?
When a search engine reads your page, it sees text and HTML, and it has to guess the rest. Is this an article or a product page? Who published it? Is that number a price? When was it last updated? Structured data takes the guesswork out. It's written with Schema.org, a shared vocabulary launched in 2011 by Google, Microsoft and Yahoo, later joined by Yandex, that gives everything a name: Article, Product, Organization, FAQPage, Event and hundreds more.
JSON-LD is the simplest way to write it. It's a block of code inside a script tag, kept apart from what visitors see, so they never notice it and your layout stays exactly the same. A typical block says: this page is an article, written by this person, published by this company, updated on this date, and it's about this topic. Search engines read it the way you'd read the label on a shipping box.
Why care now that people put their questions to ChatGPT or Google AI Overview instead of scrolling through links? Because these assistants lean partly on search engines and indexes that use structured data to understand pages. Clear markup removes ambiguity: your brand is an organization, not a common word; this price belongs to this product; this answer goes with this question. Nobody publishes how much weight markup carries inside those systems, so be wary of big promises. Think of it as a clean foundation, not a shortcut.
This tool handles the tedious part for you. It fetches your page's raw HTML without running JavaScript, works out what kind of page it is, checks which markup is already there and writes a block built only from information found on the page. Every type it adds comes with a reason, and the result includes practical tips for taking your markup further.
What do you get from this JSON-LD generator for a single page?
Not just code: enough context to understand what you're pasting, and why.
The page type, and why it was picked
Article, blog post, product page, FAQ, how-to, homepage, local business, service, software, landing page, about page, contact page, event or recipe. The generator names the type it chose and explains in one sentence what tipped the decision. When nothing fits, it sticks to generic markup.
One JSON-LD block, ready to paste
The page's main type plus the ones that belong alongside it, such as Organization, WebSite, WebPage or BreadcrumbList (the breadcrumb trail), two to six in all, combined in a single block. The copy button grabs the full script tag. The download gives you a schema.json file without the tag, so you wrap it yourself.
Connections between your page and its subject
The code goes past the bare minimum. The about and mentions properties name the topics and entities the page covers, mainEntity points to its core content, and sameAs ties your organization to its profiles elsewhere when that information exists. Questions in your headings can become FAQPage, and step-by-step content can become HowTo.
An inventory of the markup you already have
Before writing anything, the generator lists the JSON-LD already in the HTML: which types it found, how many properties they hold and whether they use @graph, the structure that groups several types in one block. It also picks up product markup written in microdata. The new code is designed not to repeat what's already there.
A reason and an impact rating for each type
Every suggested type comes with the reason it's there and an estimate of its impact on visibility in AI assistant answers: high, medium or low. If you need to keep things lean, start with the high-impact types and save the rest for later.
Tips and missed opportunities
Three to five concrete tips to get more out of your structured data, plus one to three opportunities the page is leaving on the table. Four numbers sum it all up: types generated, total properties, estimated size of the block and types already on the page.
Schema on your page, without digging through the Schema.org docs.
“Do I have to fill in every field by hand?”
No, there's no form. The values come from the page itself: title, description, body text, the questions in your headings. You don't need to know property names or formats. If something isn't on the page, it won't be in the code either, and that's deliberate: you add it yourself, knowing exactly what you're adding and why.
“My SEO plugin already adds schema. Won't I end up with duplicates?”
Yoast, Rank Math and plenty of themes already output Organization or WebSite markup. The generator reads the JSON-LD in your HTML first, shows you those types and avoids repeating them. One catch: markup added later with JavaScript, through Google Tag Manager for example, isn't in the HTML it reads. If that's your setup, remove any duplicates yourself.
“I'm not a developer. Can I still do this?”
Yes. You don't write code, you paste one block, and it doesn't change how the page looks. Each type is explained in plain language, and the copy button already includes the script tag. The trickiest part is finding where your CMS accepts custom code, and most of them have a field built for exactly that.
You have the code. How do you get it live without mistakes?
Five steps to go from the generated block to markup that's clean, tested and kept up to date.
- 01
Check every value against the page
AI wrote this code, so review it the way you'd review work from a bright intern. Check names, URLs, the logo and any sameAs links: they must point to real addresses. Make sure the breadcrumb follows your site's actual structure, and that the CSS selectors in the speakable property (the passages meant to be read aloud) exist in your HTML. If they don't, fix or delete them.
- 02
Test the code before you publish
Paste the block into the Schema Markup Validator (validator.schema.org), which flags syntax errors and unknown properties. Then run Google's Rich Results Test (search.google.com/test/rich-results) to see whether the page can qualify for enhanced search listings and which recommended fields are missing. Both tools are free and accept pasted code, so nothing touches your live site yet.
- 03
Paste it in the right place
The block belongs on the page you analyzed, ideally inside the head tag, though Google also reads it in the body. On WordPress, use a code snippet plugin or a Custom HTML block. On Webflow, use the custom code field in the page settings. On Shopify, edit the relevant template in your theme code. Avoid injecting it through a tag manager if you can: not every crawler runs JavaScript.
- 04
Confirm the markup is actually live
Once the page is published, run the generator again on the same URL. The existing markup section should now list your types, which proves they're in the raw HTML and readable without JavaScript. In Google Search Console, the URL Inspection tool shows what Google fetched, and the enhancement reports flag any errors over the following days.
- 05
Keep it in sync, then move on to other pages
Markup should describe what visitors actually see. When a price, an update date or an FAQ question changes, update the JSON-LD at the same time, or it starts telling search engines something false. Then work through the pages that matter most: your homepage, product or service pages, and content that answers the questions people in your market ask. Each page gets its own block.
Who gets the most out of this schema markup generator?
The founder running the site alone
Your site runs on Webflow, Framer or WordPress, and nobody on the team has time to learn Schema.org. One URL gets you markup for your homepage or product page, with Organization or SoftwareApplication where they make sense, plus explanations you'll actually understand.
The marketing team shipping content
A new article, guide or comparison page goes live next week. Generate the markup as soon as a public version exists, then hand the block and its explanations to your developer. They know what to paste and why, with no back and forth and no ticket that drags on for days.
The SEO or GEO consultant auditing a site
In under a minute, you see which schema types a key page has, which ones are missing and the code to close the gap. Handy for a first check on visibility in Google and in AI assistants, for showing a concrete issue before a project starts, or for a recommendation the tech team can apply as is.
The online store or local business
A product page showing price and availability, a page listing your address and opening hours: that's information search engines know how to use once it's marked up. The generator suggests Product or LocalBusiness based on what's written. With hundreds of products, use the result as a model to build into your product page template.
Ready to give your page the schema it's missing?
Paste a URL. In under a minute, you'll have an explained JSON-LD block, ready to review, test and publish.
Frequently asked questions
JSON-LD, microdata or RDFa: which format should I use?
All three express the same Schema.org vocabulary. Microdata and RDFa are attributes sprinkled through your visible HTML, tag by tag, which tends to break during a redesign. JSON-LD sits in a separate block that's easy to read, test and replace. Google recommends it whenever your setup allows, and it's the format this generator produces.
Which schema type fits which kind of page?
An article or blog post takes Article or BlogPosting. A product page takes Product, with an Offer if the price is shown. Homepages usually describe Organization and WebSite. A physical business uses LocalBusiness, software uses SoftwareApplication, events use Event, recipes use Recipe, Q&A pages use FAQPage and tutorials use HowTo. About and contact pages have AboutPage and ContactPage. BreadcrumbList, for the breadcrumb trail, works almost everywhere.
Does structured data help a page rank higher on Google?
Not directly. Google says markup helps it understand a page and can make it eligible for rich results, like star ratings, prices or breadcrumbs shown in search listings. Those can earn more clicks, but markup won't make up for thin content or a lack of links. And markup describing content that isn't on the page can earn you a manual action from Google.
Is FAQ and HowTo markup still worth adding?
For how your page looks on Google, less than it used to be: since 2023, FAQ rich results only show for well-known government and health sites, and HowTo rich results are gone. The vocabulary is still valid, though, and it clearly describes a question-and-answer or step-by-step structure, so the generator can suggest it when your page fits. Add it because it describes the page accurately, not in hopes of a fancy snippet.
Can the generated code contain mistakes?
Yes, like any AI-written code. A few safeguards limit the damage: the model only sees what's on the page, it's instructed never to invent reviews, ratings, prices or dates, and any entry that isn't valid JSON gets dropped. But perfectly valid JSON can still hold a rough URL or a poorly chosen property. Review and test before publishing.
Why can't the generator see my page's content?
It fetches raw HTML the way your server sends it, without running JavaScript, so a page built in the browser can look almost empty to it. It also fails on pages behind a login, pages that return an error, sites that block automated requests and pages that take more than 15 seconds to respond. Double-check the URL first: a failed attempt still counts toward your daily limit.
My page isn't in English. Does that work?
Yes. The generator reads the page in its original language. On this English version of the tool, the explanations, tips and opportunities are written in English, while the values in the code (names, descriptions, questions) come from the page and stay in its language. That's what you want: markup should match what visitors actually read, not a translation of it.
Is it really free?
Yes. No signup, no credit card, and nothing held back for a paid version: the full code, explanations and tips are all in the free result. You get three generations per rolling 24 hours, counted per IP address, so the tool stays available for everyone. Each generation frees up again 24 hours after you used it.
What data do you keep?
Three things: the URL you analyzed, the result (detected page type, code and tips) and your IP address, which is used to apply the daily limit. No account is created and no email address is requested. The generator only reads the public page you point it to, nothing else on your site.
Will ChatGPT cite my page once the schema is in place?
Nothing guarantees it. Structured data makes a page easier to interpret, but AI assistants also weigh the content itself, the site's reputation and what other sites say about you. The only way to know is to measure. Mentionable tracks your brand every day in ChatGPT, Claude, Perplexity, Gemini, Copilot, Google AI Mode and Google AI Overview, shows which sources those assistants cite and which competitors they recommend, and tells you what to do next. 7-day free trial, no credit card.
