Validate your structured data for Search Engines and AI Models—at no cost.

In the era of Otimização do Motor Generativo (GEO) , text on a page is not enough. Search engines and Large Language Models (LLMs) rely on Structured Data (Schema.org) to understand the semantic meaning of your content. Without it, you are just a string of characters. With it, you become an Entidade .

The MultiLipi Schema Checker is a free diagnostic instrument designed to instantly audit your code for structured data compliance, ensuring you qualify for Rich Snippets across 120+ languages without any subscription barriers.

Why Schema Infrastructure Matters

From Rich Snippets to Knowledge Graphs.

Structured data acts as a translator between your HTML and the machine.

SEO tradicional

It powers "Rich Results" like Star Ratings, FAQ drop-downs, and Product Pricing in Google Search.

GEO (AI Search)

It feeds the Knowledge Graph. When a user asks an AI, "What is the price of X?", the model looks for the Product schema to provide a precise answer.

If your Schema is broken or missing, you are invisible to these semantic engines. Our free tool ensures you never fly blind.

O Protocolo de Auditoria

The tool will return a structured report highlighting detected types, syntax format, and critical errors.

The Multilingual Advantage

Validating localized entities.

Most free schema validators only look at the structure of one language. MultiLipi's tool is engineered for Global SEO.

When you translate a page into French, your Schema must also be translated.

Bad Schema

The page is in French, but the description field in the JSON-LD remains in English.

Good Schema

The description, name, and currency fields are all localized to match the French user experience.

Use our free tool to audit your translated sub-directories (e.g., /fr/ , /es/ ) to ensure your localized schema is technically valid and linguistically synchronized.

Our free engine validates the full library of Schema.org definitions, including key business assets:
