WebSite SearchAction schema is a Schema.org pattern that tells search engines and AI agents that the site has internal search functionality. It is added to the WebSite schema block on the homepage and enables Google to display a sitelinks search box directly in branded search results.
A potentialAction property on the WebSite schema, typed as SearchAction. The target is the search URL template (e.g. https://example.com/?s={search_term_string}). The query-input is 'required name=search_term_string'.
AI agents use SearchAction to understand how to navigate the site programmatically. When answering questions that require deeper site search, the agent can construct a query URL from the schema and follow it.
Add SearchAction inside the WebSite JSON-LD block on the homepage. Spacemen Digital adds SearchAction as part of standard Organization + WebSite schema bootstrapping for every client.
