Schema Markup is a standardized vocabulary of structured data tags created collaboratively by Google, Bing, Yahoo, and Yandex (Schema.org). When you add schema markup in the recommended JSON-LD format to your website’s HTML, you provide search engines with explicit, unambiguous signals about the meaning and context of your content.
In 2026, schema markup is critical for winning Google AI Overviews (SGE citations) and prominent Rich Snippets in search engine result pages (SERPs). Instead of relying on a search bot to guess your article author, product price, or FAQ questions, schema markup delivers this structured information directly into search indexes.
