What Is Schema Markup?
Schema Markup is structured data added to a webpage so search engines can interpret its content more clearly. The markup identifies details such as a product, service, organisation, event, or article. Search engines may use that understanding to create enhanced search results, although adding Schema Markup does not guarantee a rich result.

How Schema Markup Works

Schema Markup uses a recognised vocabulary to label information on a webpage. The code can identify the page type and describe relevant properties, such as a service name, location, author, or review. Search engines read these labels alongside the visible page content.

Structured data commonly appears in JSON-LD, which sits in the page code and does not usually change the visible design. The marked details must match the content that people can see. Search platforms may then use the information for features such as service details, breadcrumb trails, or article enhancements, subject to their own systems and policies.

Expert Note
When we work on Technical SEO, we match Schema Markup to the page purpose and visible content. We check the code for valid syntax, accurate properties, and consistency with the site’s templates. We also review the rendered page so markup does not describe information that users cannot find.
Schema Markup in Practice: A Real-World Example
A Geelong plumber’s service page could use Schema Markup to identify the business, the plumbing service, and its service area. The visible page must contain the same details so search engines receive a consistent description.
