Ready for ChatGPT, Geminiand Perplexity?

01

Structured data gives AI systems unambiguous facts (who, what, where, price) they can quote.

02

The completeness score highlights recommended properties, not just required ones.

How it works

  1. 01

    Supported types

    Organization, LocalBusiness, Article, Product, FAQPage, Event, Person, Recipe and more, combined into one @graph when you need several.

  2. 02

    Validation

    Checks required and recommended properties against Google's rich result rules as you type, so you ship markup that is eligible, not just valid JSON.

Questions, answered
