JSON

JSON, short for JavaScript Object Notation, is a lightweight data format used for data exchange.

It is easy for humans to read and write and easy for machines to parse and generate. JSON is often used to transmit data between a server and a web application, as an alternative data format to XML.

In the context of SEO, the JSON-LD version (JavaScript Object Notation for Linked Data, a JSON-based Linked data interchange format) is a popular method for implementing structured data, which can help search engines better understand the content of a web page.
