Structured data vocabulary

Schema.org is a shared structured data vocabulary that helps search engines and AI systems understand what a page, product or business is.

What is Schema.org?

Schema.org is a shared vocabulary of types and properties used to describe page content in a machine-readable way – a product with its price and availability, a business with its address, or an article with its author. The project was started by Google, Microsoft and Yahoo, with Yandex joining later, and Google recommends embedding the data as JSON-LD. Valid structured data can unlock rich results and helps a business be recognised as a single entity.

How we use it at Koda Plus

Structured data in JSON-LD is a standard part of our technical SEO work: in online shops we keep Product markup consistent with price and stock levels, because a mismatch with the product feed triggers warnings in Merchant Center. For local SEO we add LocalBusiness markup to location pages, and during migrations, such as WooCommerce to Medusa.js, we check structured data parity between the old and the new shop. Our own site publishes an Organization and WebSite graph plus BlogPosting on articles, and our SEO audit script flags pages with missing JSON-LD or malformed JSON.

When it makes sense

  • Your shop wants rich results showing price and availability
  • You operate locally and need consistent address data
  • You are planning a platform migration and want to keep visibility
  • You want AI systems to describe your brand accurately

Frequently asked questions
Schema.org

  • What is the difference between Schema.org and JSON-LD?

    Schema.org is the vocabulary: it defines types such as Product or Organization and their properties. JSON-LD is the format used to embed that data in a page as a separate script. Google recommends JSON-LD, although the same vocabulary can also be written as Microdata or RDFa.

  • Does structured data improve Google rankings?

    Not directly – it is not a ranking factor in itself. It helps search engines understand the content and can unlock rich results, such as price, availability or product ratings, which can improve click-through rates. That is why we treat it as a foundation of technical SEO rather than a shortcut to higher positions.

  • How do I test structured data on my website?

    The quickest checks are Google’s Rich Results Test and the validator at validator.schema.org. Site-wide errors and warnings also appear in Google Search Console reports. For online shops it is worth comparing Product markup with the data in Merchant Center as well.
