Structured data
grader
JSON-LD is how search engines and AI assistants learn facts about you - and one missing comma silently voids a whole block. Type your address and get every block fetched, parsed, graded and gap-filled. We fetch your page securely - nothing else leaves your browser.
Fetch. Parse. Patch the gaps.

Coverage checklist
Yetty serves valid structured data on every page automatically - organization, pages, breadcrumbs - generated from your real content.
The six types search
and AI look for
Organization / WebSite
Who you are: name, logo, links. The anchor every other fact hangs off - and what AI cites you by.
WebPage / Article
What this page is - a page, a post, a guide - with headline and dates machines can trust.
BreadcrumbList
Where the page sits in your site - Google shows it as the neat path under your result.
FAQPage
Your questions and answers as data - eligible for rich results, and lifted directly into AI answers.
LocalBusiness
Address, hours, phone - feeds maps, "near me" searches and every assistant asked "is it open now?".
Product
Price, availability, reviews - what makes your listing show rich details instead of a bare link.

How do I check if my structured data is valid?
Enter your page address into this grader (or paste the HTML): it extracts every JSON-LD script block, parses it, and points at the exact position of any syntax error. A single missing comma silently voids a whole block - search engines and AI assistants just skip it without telling you, which is why broken schema is so common.
What schema types should a small business website have?
Start with four: Organization or WebSite (who you are), WebPage or Article on each page (what this page is), BreadcrumbList (where the page sits), and LocalBusiness if you have a physical location - it feeds your hours and address to maps and "near me" searches. Add FAQPage and Product where they genuinely apply.
Does structured data help with AI search?
Yes. JSON-LD gives ChatGPT, Perplexity and Google facts as data instead of prose to guess from: your name, type, address, prices, questions and answers. Pages with clean structured data get summarised more accurately and cited with the right details.
