Schema validator

Schema markup (JSON-LD) is how you tell Google and AI assistants exactly what your page is about — your business, your FAQs, your products. Pick one of your sites and this tool fetches its homepage the way a crawler sees it, finds every schema block, checks them for errors, and tells you how to fix them in plain English.
