JSON-LD (JavaScript Object Notation for Linked Data ) is a structured data recommended by the W3C ( World Wide Web Consortium) and preferred by Google , designed to encode and transport Linked Data on the web. It acts as a method for annotating the content of a web page in a way that is easily understood by machines, especially search engines. Using the familiar syntax of JSON, JSON-LD allows developers and content creators to describe entities (such as people, products, events, or articles) and their properties and relationships, transforming the ambiguous text of a page into a set of clear and interconnected data.

The main characteristic of JSON-LD is its practical and discreet implementation. The code is inserted within a tag. no cabeçalho () ou no corpo () de um documento HTML, o que o separa completamente do conteúdo visível para o usuário. Essa separação facilita a manutenção e a implementação sem o risco de interferir no layout ou na apresentação visual da página, uma vantagem significativa sobre outros formatos como Microdata e RDFa, que se misturam ao código HTML. O JSON-LD utiliza um contexto (@context) para definir o vocabulário, sendo o Schema.org o mais comum, permitindo que os dados sejam padronizados e compreendidos universalmente na web.

For SEO and content marketing semantic and technical SEO strategy . Its correct implementation is a prerequisite for a page to qualify for rich results in search . These results, which include elements such as star ratings, FAQ sections, product prices, and event schedules, increase visibility , improve click-through rate (CTR), and offer a more informative user experience
