Schema Markup
Schema Markup is a structured data vocabulary that uses microdata, JSON-LD, or RDFa formats to annotate web content, enabling search engines like Google to better understand and display information in rich results such as snippets, knowledge panels, and carousels. It is based on schemas.org, a collaborative project by major search engines to standardize markup for entities like events, products, recipes, and organizations. This markup helps enhance search engine optimization (SEO) by providing explicit context to web pages.
Developers should learn and implement Schema Markup to improve a website's visibility in search results through rich snippets, which can increase click-through rates and user engagement. It is particularly useful for e-commerce sites, local businesses, content publishers, and any application where structured data can drive better search performance, such as for events, recipes, or FAQs. Using Schema Markup also supports voice search and AI assistants by providing clear, machine-readable data.
