Summary

SchemaValid is a free browser-based toolkit for structured data and technical SEO. Its tools include JSON-LD generators, a schema validator, sitemap utilities, and robots.txt tools, alongside utilities for text and content, AI search, analytics, campaigns, and tasks such as IBAN validation. The validator checks either 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; visitors can make five URL checks per minute. Pasted-code validation runs in the browser without uploading or storing the code or linking it to an account. The AI Search Readiness Checker scores pages out of 100 across eight categories, using the page plus 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 tools are available without charge or registration, though availability may change.
