SchemaValid is a browser-based toolkit for JSON-LD, structured data and technical SEO. Its tools include schema validation, sitemap and robots.txt utilities, plus tools for text and content, AI search, analytics, campaigns and other 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 checks provide scorecards for 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 without uploading or storing the code or tying it to an account. The AI Search Readiness Checker scores a page out of 100 across eight categories, using the page and its robots.txt, sitemap.xml and llms.txt. A robots.txt editor offers a live preview for crawler rules, AI-bot access and sitemap settings. The tools are free without registration, though availability may change.
