What does Structured data checker do?

It helps you inspect or process this value and get a readable result quickly.

Is my input saved?

Local tools run in the browser when possible. Server-side checks only use the input needed to complete the lookup.

Does missing structured data block indexing?

Usually no, but it weakens explicit understanding of page type, FAQ, breadcrumbs, and tool capabilities, and can reduce rich-result opportunities.

Which schema types are useful for tool pages?

Check WebApplication, FAQPage, BreadcrumbList, Article, or HowTo only when they match visible page content. Do not add entities that the page does not actually provide.
