Does structured data improve rankings?

Not as a direct ranking factor. It makes a page eligible for rich results — stars, prices, FAQ dropdowns, breadcrumbs — which raise click-through rate at the same position. The gain is in clicks, not position.

Why is my valid schema not showing a rich result?

Eligibility is not a guarantee. Google renders rich results at its own discretion, based on query intent, page quality and trust in the site. Valid markup, content that matches it, and an indexed page are prerequisites, not a promise.

Should I use JSON-LD, Microdata or RDFa?

JSON-LD. Google explicitly recommends it, it sits in a single script tag rather than being threaded through your HTML, and it survives template changes that would break inline Microdata attributes.

Can I have more than one schema type on a page?

Yes, and you usually should. An article page can legitimately carry Article, BreadcrumbList and FAQPage at once. Put them in a single @graph array or separate script tags — both are valid.

JSON-LD Schema Validator

Validate JSON-LD structured data before you deploy — catches missing required fields Google uses to render rich results.

JSON-LD markup

Valid

JSON parses and all required fields are present.

In short

A JSON-LD validator parses your structured data and checks it against schema.org: valid JSON syntax, a resolvable @context, a recognised @type, and the properties Google requires before it will render a rich result. Most failures are not syntax errors — they are valid JSON missing a required property such as Product.offers or Review.author. Paste your markup below for a line-by-line verdict.

Worked example

What the output looks like

Input: {"@context":"https://schema.org","@type":"Product","name":"Trail Runner 3","aggregateRating":{"@type":"AggregateRating","ratingValue":"4.6"}}
Output: 2 errors — AggregateRating is missing required ratingCount or reviewCount; Product is missing recommended offers
How to read it: The JSON is syntactically perfect, which is why browser tooling reports nothing. Google still rejects the rich result: a rating with no review count cannot be verified. Adding reviewCount and an offers block with price and priceCurrency makes the product eligible.

How it works

Paste the full script block contents

Include the outer braces. If your page emits several graphs, validate each separately — one broken block can invalidate the whole script tag.

Fix required properties before optional ones

Google splits properties into required and recommended. A missing required property disqualifies the rich result entirely; a missing recommended one only reduces how much detail is shown.

Make the markup match the visible page

Structured data describing content a visitor cannot see is a policy violation and a common cause of manual actions. Every rating, price and FAQ answer in the markup must appear on the page.
