Structured Data Checker

Structured data tells search engines in a fixed vocabulary what a page is about: who your company is, where it is located, when it is open, what a product costs. Google uses this information for enhanced search results, AI search engines for their answers. The check reads all markup on your page and tells you whether it is complete and free of errors.

How to read the result

We load the page and look for all three common formats: JSON-LD, Microdata and RDFa. Every data type found is listed individually and checked against the requirements Google publishes for rich results.

OKThis point is implemented correctly.
ReviewNot an acute error, but room for improvement.
ProblemLikely has a negative effect and should be fixed.
InfoFor information, without rating.

Data types found

You see every type your page marks up, such as Organization, LocalBusiness, WebSite, Article, Product, FAQPage, BreadcrumbList, Event or Recipe. JSON-LD blocks using @graph are split into their individual entries so nothing gets lost.

Syntax errors

A missing comma or a wrong quotation mark is enough for Google to ignore the entire JSON-LD block. We report such errors along with the position where parsing stops.

Required and recommended properties

For the most common types we check whether the properties Google requires or recommends are present. For a product these are, for example, name, price and availability, for an article headline, date and image. Missing required properties are red, missing recommendations yellow.

Possible rich results

For each type we show which appearance in Google Search it enables, such as stars and price for products, breadcrumbs instead of the URL, or dates for events. Whether Google actually shows them is up to Google.

Recommended basics

If basic information is missing, we suggest it. For almost every company, Organization or LocalBusiness with address, contact details and opening hours makes sense. It helps Google and AI search engines identify your company clearly.

Why structured data brings more visibility

Search engines read text well, but not perfectly. Whether a number is a price, a phone number or a house number, they have to guess. Structured data removes the guesswork: it states clearly what each piece of information means.

The most visible benefit is rich results. A search result with rating stars, price, event date or breadcrumb path stands out more than a plain blue line and gets clicked more often. Structured data is not a direct ranking factor, but it is often a big lever for click-through rate.

The second benefit is growing in importance: AI search engines such as ChatGPT, Perplexity or Google’s AI Overviews like to rely on clearly marked-up facts. If name, address, services and opening hours are stored properly, your company is represented more accurately.

Once set up, structured data usually runs automatically. The only thing to remember is to check it again after a relaunch or theme change, because it is often lost in the process.

Example: LocalBusiness for a Vienna company

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "LocalBusiness",
  "name": "Musterfirma GmbH",
  "url": "https://www.musterfirma.at/",
  "logo": "https://www.musterfirma.at/logo.png",
  "telephone": "+43 1 234 56 78",
  "email": "office@musterfirma.at",
  "address": {
    "@type": "PostalAddress",
    "streetAddress": "Musterstraße 1",
    "postalCode": "1010",
    "addressLocality": "Wien",
    "addressCountry": "AT"
  },
  "openingHoursSpecification": [{
    "@type": "OpeningHoursSpecification",
    "dayOfWeek": ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday"],
    "opens": "09:00",
    "closes": "17:00"
  }]
}
</script>

The block can go in the <head> or at the end of the <body>, ideally on the homepage or contact page. On WordPress, plugins such as Yoast SEO or Rank Math generate part of it automatically, but you usually have to add address and opening hours yourself.

Frequently asked questions about structured data

Which format should I use?

JSON-LD. Google explicitly recommends it because it sits separately from the visible HTML and is easy to maintain. Microdata and RDFa are still read, but they are more error-prone because they are woven directly into the page content.

My FAQ markup is correct, but Google does not show it.

Since 2023, Google only shows FAQ rich results for a small number of websites, mainly government and health sites. The markup does no harm, though: AI search engines and other services still like to read questions and answers from it.

Does structured data guarantee a rich result?

No. It is a prerequisite, but Google decides depending on the search query and the quality of the page whether the enhanced appearance is shown. Complete and error-free data increases the chances considerably.

May the data say something different from the page?

No. Whatever is in the structured data must also be visible to visitors, such as price, rating or opening hours. Google may treat hidden or embellished information as a violation and remove rich results for the entire website.

How long does it take for Google to see the change?

As soon as Google recrawls the page, usually within days to a few weeks. In Google Search Console you can request reindexing via URL Inspection and follow the status in the “Enhancements” section.
