Search and the web
Machine-readable statements embedded in a page that say what its content means rather than how it looks.
Also called Schema.org · JSON-LD · Микроразметка
It is what turns a string into a thing: this is an organisation, with this licence number, at this address; this is an offer, at this price, in this currency. Search engines use it for result features, and assistants use it to resolve which entity a page is about — which is the more durable of the two benefits.
Identity is the part worth getting right. Give the organisation one stable @id and reference it from every other node on the site rather than repeating the name. That is the difference between a search engine seeing forty pages that mention a company and seeing forty pages published by one.
Structured data that disagrees with the visible page is the one reliable way to have it ignored, and repeated often enough it costs the site its eligibility for result features entirely. Generate the markup from the same data the page renders, so the two cannot drift.
The definitions are the easy part. Whether the figure on your dashboard was computed this way is a different question, and usually the more expensive one.
