The short answer

Schema markup is structured data added to a page's code that helps search engines understand what the content means. Structured data is information in a standard format search engines can read reliably. Rich snippets are enhanced results showing extra detail like ratings or FAQs; they can improve clicks but do not directly raise rankings and are never guaranteed. SERPs are search engine results pages. Schema.org is the shared vocabulary of data types that schema draws on. Google decides when to show rich results.

Meaning, not just words

What schema markup and structured data are

Schema markup is a form of structured data added to a web page's code that helps search engines understand what the content means, not just what it says, labelling information like a business, product, article or FAQ. Because it clarifies meaning, schema can help search engines display richer results, though it does not guarantee any particular appearance. Structured data is information organised in a standard format so search engines can read and interpret it reliably, with schema markup being the common vocabulary used to provide it. It turns page content into machine-readable facts; because it makes meaning explicit, structured data helps search engines understand and potentially feature your content, which is why we implement it with JSON-LD on every build.

Rich snippets, SERPs and Schema.org

Rich snippets, SERPs, why schema matters, and Schema.org

Rich snippets are enhanced search results that show extra detail, such as ratings, FAQs or images, often powered by schema markup, and they can help by making a result more prominent and informative, which may improve clicks, though they do not directly raise rankings and are never guaranteed. Because Google decides when to show them, schema makes eligibility possible rather than certain. SERPs are search engine results pages, the pages of results you see after a search, and schema is important because it helps search engines understand your content and can make it eligible for richer, more useful result formats. Because clearer understanding can support visibility, schema is a valuable part of technical SEO, though it is one factor among many. Schema.org is a shared vocabulary of structured data types, created collaboratively by major search engines, that defines how to describe things like businesses, products and events. It is the standard schema markup draws on; because it is widely supported, using Schema.org types is the reliable way to mark up content that search engines will recognise, and it underpins every one of our schema type implementations.
