A person looking at your page sees right away: That's a price, that's a date, that's the company name. A machine at first sees only text. Structured data is the way to tell it exactly that: This is a company, that's an article, that's a review.
How does it work?
In the background there's a small, invisible block of code on the page, usually in JSON-LD format. It uses a shared vocabulary called Schema.org that search engines and AI understand. The visitor sees none of it, but afterwards the machine knows exactly what it's about.
An example: Instead of Google having to guess whether "Nucez Software" is a company, a product or a typo, the structured data says it clearly: This is an organization, here's the address, here's how to get in touch.
What does it get you?
- Better display in search. Star ratings, event dates or Q&A blocks right in the search result come from structured data.
- Clarity for AI. If you state in machine-readable form who you are and what you offer, you make it easy for an AI to classify you correctly and cite you.
- Fewer misunderstandings. The machine doesn't guess, it reads.
Typical markup
- Organization or local business: name, address, contact.
- Articles and blog posts: title, date, author.
- Services and products.
- Breadcrumb navigation, so the structure of the site is clear.
This website uses exactly this kind of markup, for the company, the products, the blog posts and the individual services.
An honest word
Structured data isn't a magic trick that shoots you to the top. It's a foundation. And one rule always applies: Only mark up what's actually on the page. If you mark up things that don't exist, you'll get caught.
