Strukturierte Daten

This term refers to extra organised information added to a page so search engines can understand the content in a more precise way. It is usually written in a standard format such as JSON-LD and describes things like a business, service, product, article, FAQ, review, event, breadcrumb or location. Visitors do not usually see this information as normal page text, but search engines can read it as a structured explanation of what the page contains. The purpose is clarity, not decoration or manipulation.

For a glossary definition, the easiest way to understand it is to think of it as labelling page content in a language search engines recognise. A normal visitor can read an FAQ question and answer on the page. Structured data can mark that same question and answer as FAQ content. A visitor can see a business name and contact details. Structured data can mark them as organisation or local business information. This helps search engines connect the page with the correct meaning, provided the markup accurately reflects visible content.

In Wix and Wix Studio projects, structured data can be added through SEO settings, custom code or dynamic page patterns. It becomes especially useful when a website uses CMS collections. For example, a collection may include fields for a service name, description, FAQ questions and answers. A dynamic page can display those fields to visitors, while structured data can describe the same information in a machine-readable format. This creates a consistent SEO system across many pages, which is useful for service, industry, location and glossary content.

The quality of structured data depends on accuracy. It should not claim that a page contains reviews, services or FAQs if that information is not actually visible to visitors. It should also be tested because missing fields, copied code and invalid formatting can reduce usefulness. Common mistakes include placing the same schema on every page, forgetting to update it when content changes, or using markup that does not match the page purpose. When used correctly, structured data supports technical SEO by making pages easier to interpret, especially on larger Wix websites with many connected CMS items.
