SchemaValid
Göttingen, Germany
What it is
SchemaValid is a browser-based toolkit for structured data and technical SEO. It offers JSON-LD generators, a schema validator, sitemap and robots.txt tools, plus utilities for text and content, AI search, analytics, campaigns, and tasks such as IBAN validation. The validator checks a live URL or pasted JSON-LD and reports an SEO score, errors, warnings, and rich-results readiness. URL scorecards cover 16 schema types, including Organization, Product, Article, Recipe, Event, FAQPage, JobPosting, Course, VideoObject, and SoftwareApplication; the limit is five URL checks per minute per visitor. Pasted-code validation runs locally in the browser without uploading or storing the code or tying it to an account. Its AI Search Readiness Checker scores a page out of 100 across eight categories, reading the page, robots.txt, sitemap.xml, and llms.txt. A visual robots.txt editor provides a live preview for crawler rules, AI-bot access, and sitemap settings. The online tools are free and require no registration, though SchemaValid reserves the right to change, restrict, or discontinue them.
