Enter any page URL and instantly see every JSON-LD schema object it contains — the types, their properties, and any invalid or thin markup that could be costing you rich results. No signup required.
A schema object is a small block of machine-readable data you add to a web page that spells out exactly what the page is about — that this is a Product priced at $49, that this is an Article written by Jane Doe on the 3rd of March, or that this is a LocalBusiness open until 6pm. Search engines read these objects to understand your content far more precisely than they could from the visible text alone, and they use them to build rich results — the star ratings, FAQ drop-downs, breadcrumbs, and price snippets you see in Google.
These objects follow the shared vocabulary at Schema.org and are most commonly written in
JSON-LD — a tidy block of JSON wrapped in a <script type="application/ld+json">
tag in your page's HTML. Two older formats, Microdata and RDFa, embed the same
information directly into your HTML attributes. Google recommends JSON-LD, and this checker reads all three.
Drop in any public page URL — a homepage, product page, blog post, or landing page you want to inspect.
Our server safely requests the page and reads only its public HTML source — the same thing a search crawler sees.
Every <script type="application/ld+json"> block is pulled out and parsed, including nested @graph structures.
Each schema object is listed with its @type, a plain-English explanation, and the properties it declares.
Broken JSON, missing @context or @type, empty values, and absent recommended properties are all highlighted.
We also detect Microdata (itemscope/itemtype) and RDFa so you get a complete picture of every markup format on the page.
Star ratings, FAQ accordions, recipe cards, event dates, and price snippets all come from valid schema. They make your listing bigger and far more clickable.
A result with review stars or an FAQ drop-down takes up more space and earns more clicks than a plain blue link — often without any change in ranking position.
Structured data helps Google, Bing, and AI answer engines understand your entities and relationships, improving how your brand is represented and cited.
One misplaced comma can invalidate an entire JSON-LD block and silently strip your rich results. Regular checks catch these errors before they cost you traffic.
When we find one of these types, the report tells you what it does and which recommended properties are missing. Here are the ones you'll run into most often:
Your brand or business location — powers the knowledge panel, logo, and local pack.
Editorial content — eligible for the Article rich result and Top Stories carousel.
Items for sale — shows price, availability, and review stars right in search.
The page navigation trail Google shows in place of the raw URL.
Question lists and step-by-step guides that expand directly in the results.
Star ratings — one of the highest-impact rich results for click-through.
Enables the Sitelinks Search Box for your brand queries.
Content-specific cards with times, dates, thumbnails, and ratings.
A trailing comma, an unclosed brace, or a stray quote makes the whole JSON-LD block unreadable. Search engines skip it entirely — no error, just no rich result. Our checker shows you exactly which block failed and why.
Without @context, a parser does not know you mean the Schema.org vocabulary. Without @type, it cannot tell whether the object is a Product, an Article, or something else. Both are essential.
A Product with no offers, or an Article with no headline, is technically valid JSON but will not qualify for the rich result. We flag the recommended properties Google expects for each type.
Fields like "name": "" or leftover template values ("image": "{{IMAGE_URL}}") pass JSON parsing but fail validation. We surface empty values so they do not slip through.
Schema must reflect what a user actually sees. Marking up a rating that is not visible on the page, or a price that differs from the page, violates Google guidelines and risks a manual action.
