Structured data
Structured data is information added to a web page in a standard format, usually JSON-LD using the Schema.org vocabulary, that tells search engines and AI systems exactly what the page describes: an article, an organisation, a question and its answer. It turns what a person reads into facts a machine can use.
What it means
A person can tell from context that a page is an article by a named author, published on a date. A machine does better when it's told directly. Structured data does that, and it's one of the ways a site becomes easier for AI systems to describe accurately.
It must match the page. Markup that claims something the visible page doesn't show is treated as spam, and it undermines the trust it was meant to build.
How we use it
Our method This site generates its structured data from the visible page, so the two can't disagree: every article carries its author and dates, every set of questions its answers, every page its breadcrumbs, and this glossary its terms.
