Free schema markup generator (JSON-LD) for SEO & AI search
This free tool — built by a Singapore SEO agency — generates valid JSON-LD structured data you can paste straight into your page. No signup, no limits, and it runs entirely in your browser. Structured data helps search engines and AI answer engines understand your content, which is what makes pages eligible for rich results and, increasingly, for citation in AI Overviews, ChatGPT and Perplexity.
Which schema types matter most for AI search (AEO)?
- FAQPage — question-and-answer content maps directly to how people ask AI assistants, making it some of the most citable structured data you can add.
- HowTo — step-by-step instructions that answer engines love to summarise.
- Article — author, publisher and date signals that support E-E-A-T and help engines attribute your content.
- LocalBusiness — essential for Singapore businesses appearing in local and map results.
- Organization — defines your brand as an entity in the knowledge graph, the foundation of being recognised (and cited) by AI.

LocalBusiness schema for Singapore businesses
If you have a physical presence or serve a defined area, LocalBusiness schema is one of the highest-value markups you can add. Get the details right: use your exact, consistent NAP (name, address, phone) matching your Google Business Profile and website footer; format the address with the Singapore postal code and addressCountry: SG; add accurate openingHours; and include priceRange and areaServed where relevant. Consistency across your site, your schema and your Google Business Profile is what builds the entity trust that powers local rankings and map-pack visibility.
Common schema markup mistakes to avoid
- Marking up content that isn’t on the page. Schema must reflect visible content — inventing FAQs or reviews that users can’t see risks a manual action.
- Mismatched data. A different phone number or business name in your schema than on the page confuses engines and erodes trust.
- Invalid JSON. A single missing comma or bracket invalidates the whole block — always run it through a validator (this tool outputs clean, ready-to-validate JSON-LD).
- Over-nesting or wrong types. Use the most specific correct type, and don’t stack unrelated schemas hoping for more rich results.
How schema supports E-E-A-T and AI citations
Article, Person, Organization and Publisher markup tells engines who is behind the content and who published it — the machine-readable side of Experience, Expertise, Authoritativeness and Trust. For AI search specifically, clean entity and Q&A markup reduces ambiguity about what your page says and who says it, which is one of the conditions that makes an answer engine more willing to quote you. Schema won’t force a citation, but its absence makes you easier to overlook.
Frequently asked questions
Is JSON-LD better than microdata for schema?
Yes — Google recommends JSON-LD, and it’s far easier to maintain because it lives in a single script block rather than being woven through your HTML. This tool outputs JSON-LD.
Does schema markup help with AI Overviews and ChatGPT?
It helps them read and trust your content. Clean structured data won’t force a citation, but it removes ambiguity about what your page says and who published it — which is one of the conditions that makes AI engines more willing to quote you. This is a core part of Answer Engine Optimisation.
Will schema markup instantly improve my rankings?
Schema is not a direct ranking factor, but it can earn rich results and improve how engines and AI understand your pages — both of which affect visibility and click-through. It’s high-leverage, low-risk, and quick to add.
Do I need LocalBusiness schema for my Singapore business?
If you have a storefront, office, or serve a specific area, yes — it’s one of the strongest local signals you can add, and it reinforces your Google Business Profile. Pure e-commerce or national sites may prefer Organization schema instead.
Can I use multiple schema types on one page?
Yes, when they genuinely describe the page — for example an Article plus an FAQPage plus BreadcrumbList. Just make sure each type reflects real, visible content on that page.
Will Google penalise incorrect schema?
Invalid schema simply won’t generate rich results. However, deliberately marking up content that isn’t visible to users (fake reviews, hidden FAQs) can trigger a structured-data manual action, so keep your markup honest.
Does this work with WordPress and Rank Math or Yoast?
Yes. You can paste the generated JSON-LD into a custom HTML block, your theme’s head, or a code snippet plugin. Many SEO plugins also generate some schema automatically — use this tool for the types they don’t cover, and avoid duplicating the same type twice.
