Check structured data and JSON-LD

How well a website describes its content in machine-readable form.

What is measured here

This page checks whether JSON-LD or other structured data is embedded, which types appear and whether basic types such as WebSite, Organization, BreadcrumbList, Product, Article or FAQ are detectable.

Why this module matters for AI / LLM visibility

Structured data helps not only classic search engines. It also gives LLM-based systems clearer hints about what a page is, which company it belongs to and what page type or context it represents.

What the free online version can already check here
  • number and types of detected JSON-LD blocks
  • warning for missing base types
  • visible demo snippets from structured data
What the full version adds
  • mapping schema types to page templates
  • full Product / Service / FAQ / Organization recommendations
  • comparison against competitors and SERP needs
Demo evaluation for the most recently checked URL

If you already checked a URL on the main page, CheckCom shows a live or demo evaluation for this exact module here. Without a previous check, a sample result is loaded automatically.

Note: the free web demo only checks signals that can be measured online quickly and sensibly. Expensive provider, model or market runs remain part of the premium version.
