Structured data for AI

Structured data is the single highest-leverage change on most sites. It tells a machine what your page is, not just what it says, and that difference is what lets an answer engine describe and quote you correctly instead of guessing.

Why it matters more for AI than it did for search

A person reading your page infers that a block of text is your pricing, your company name or an answer to a question. A machine does not, unless you tell it. Schema.org markup, written as JSON-LD in the page, is that explicit description. When an answer engine can read a clean statement of what you are, it is far less likely to confuse you with a namesake, misquote your pricing or skip you because it could not work out what the page was for.

The types worth adding first

• Organization. Your name, logo, and sameAs links to your profiles. This is how an engine builds a confident picture of who you are.
• Product or Service. What you sell, with price and availability where it applies, so a buyer question can be answered with real detail.
• Article. On your guides and posts, with author, publisher and dates, so your content is recognised as maintained and attributable.
• FAQPage. On pages that answer questions, so each question and answer is machine-readable as a discrete pair.
• BreadcrumbList. So the engine understands where a page sits in your site.

How to add it without breaking anything

Use JSON-LD in a <script type="application/ld+json"> block rather than inline microdata. It keeps the markup separate from your visible HTML, which is easier to maintain and less likely to drift out of sync. Describe only what is genuinely on the page, and keep the markup and the visible content consistent. Then validate with Google's Rich Results test and the schema.org validator before you ship.

The mistakes that waste the effort

• Marking up content that is not on the page. Schema must reflect what a visitor actually sees, or it is misleading and can be ignored.
• Leaving it invalid. A single malformed field can invalidate the whole block. Validate every time.
• Stopping at the homepage. Every important page deserves the right type, not just the front door.
