Schema Markup Generator
Valid JSON-LD for the six schema types that matter most, generated from a simple form.
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "FAQPage",
"mainEntity": [
{
"@type": "Question",
"name": "What is Generative Engine Optimization?",
"acceptedAnswer": {
"@type": "Answer",
"text": "GEO is the practice of structuring content so language models retrieve, trust and cite it in generated answers."
}
},
{
"@type": "Question",
"name": "How is GEO different from SEO?",
"acceptedAnswer": {
"@type": "Answer",
"text": "SEO optimises a page for a position in a ranked list. GEO optimises individual passages for being quoted inside an answer."
}
}
]
}
</script>Structured data must describe content a visitor can actually see on the page. Markup that does not match the visible page is a policy violation and can trigger a manual action.
About the schema markup generator
Why JSON-LD rather than microdata
Google explicitly prefers JSON-LD. It sits in a single script block, is independent of your visible markup, and does not break when a designer restructures the page. Microdata and RDFa still work but are harder to maintain.
Where to place it
Anywhere in the document — head or body both work. One script block per page is cleanest; if you need several types, combine them into a single @graph array rather than emitting multiple blocks.
Schema and AI answers
Structured data gives models an unambiguous machine reading of your entities, prices, ratings and relationships. It is not a citation guarantee, but it removes ambiguity that otherwise makes a model hedge or omit you.
Questions
Does schema markup improve rankings?
Not directly. It makes rich results eligible, which affects click-through rate, and it gives search and AI systems a precise reading of your content. Both matter; neither is a direct ranking boost.
What if the markup does not match the visible page?
That is a policy violation and can trigger a manual action. Structured data must describe content a user can actually see on the page.
One page at a time is slow.
Aeologic runs these checks across every URL you own and tells you which twenty to fix first.
