About Us

What We Do

Online Schema Generator is a set of 15 free tools that turn a form into valid Schema.org JSON-LD: Organization, LocalBusiness, Service, Product, Review, AggregateRating, Article, FAQ, Breadcrumb, Event, Video, Course, JobPosting, Software/App, and the WebSite sitelinks search box. No account, no payment, no limits.

How We Build These Tools

Most schema generators will happily hand you markup that Google cannot use. We build against the opposite goal — if the output would fail, we would rather tell you than let you paste it.

• Required fields are checked as you type. Every generator knows the properties Google actually requires for that type, and names the missing ones next to the preview before you copy anything.
• Controlled values are dropdowns, not free text. Properties like availability, itemCondition and courseMode only accept real Schema.org values, so you cannot produce https://schema.org/In Stock by typing it that way.
• Incomplete data is omitted, never faked. A partial salary or an incomplete video clip is left out of the JSON-LD rather than emitted in a shape that fails validation.
• Your inputs stay in your browser. Generation runs entirely client-side. We do not upload, log, or store what you type.
• Changes are written down. Every correction is recorded in our public changelog.

We do not claim schema causes rankings. Structured data makes a page eligible for rich results; whether Google shows them depends on your content and their policies. Validate anything you publish with the Rich Results Test and the Schema Markup Validator.

Who Maintains This

Online Schema Generator is built and maintained by Adil Arfan at Lookario Software Design in Dubai, United Arab Emirates. The site launched in 2025. The tools exist because we needed them ourselves and could not find generators that checked their own output — so we built ones that do.

There is no sales team and no paid placement. The generators do not upsell anything, and the site is funded by advertising, which is why you will see a small number of ad units — deliberately none above the tool itself.

If a generator produces markup you believe is wrong, tell us. Structured data requirements change, and we would rather hear about a mistake than leave it live. Write to support@onlineschemagenerator.com or use the contact form — every report reaches a human, and corrections go out through the public changelog.
