STRUCTURED-DATA<\/a> refers to a standardized format for providing information about a web page and classifying its content. By implementing specific markup, website owners help search engines like GOOGLE-SEARCH<\/a> and BING<\/a> understand the context of the data. This is primarily achieved using the SCHEMA-ORG<\/a> vocabulary, which was developed through a collaboration between GOOGLE<\/a>, MICROSOFT<\/a>, YAHOO<\/a>, and YANDEX<\/a>.<\/p> The three most common formats for STRUCTURED-DATA<\/a> are JSON-LD<\/a>, MICRODATA<\/a>, and RDFA<\/a>. As noted by Google Search Central<\/a>, JSON-LD<\/a> is the preferred format for modern SEARCH-ENGINE-OPTIMIZATION<\/a>. When correctly applied, this data can trigger RICH-RESULTS<\/a>, such as review stars, recipe cards, and event snippets, which improve the CLICK-THROUGH-RATE<\/a> from search engine result pages.<\/p> Furthermore, STRUCTURED-DATA<\/a> is a fundamental component of the SEMANTIC-WEB<\/a>. It provides the building blocks for the KNOWLEDGE-GRAPH<\/a>, enabling ARTIFICIAL-INTELLIGENCE<\/a> to perform more complex reasoning and data retrieval tasks. By categorizing METADATA<\/a>, it bridges the gap between human-readable content and machine-processable information.<\/p>
