The Sitelinks Searchbox lets users search your site directly from Google's search results page, reducing friction for brand-aware users and increasing the click-through quality from branded queries.
Quick Reference
- Add
WebSiteschema withSearchActionto signal that your site has search functionality to Google - This enables Google to show a Sitelinks Searchbox below your brand's search result for branded queries
- The Searchbox only appears at Google's discretion — the schema is a signal, not a guarantee
- The
query-inputproperty must follow the formatrequired name=search_term_string
Check
Check the homepage (or primary entry URL) for a <script type='application/ld+json'> block with "@type": "WebSite" and a potentialAction of type SearchAction. Verify target is a valid search URL template and query-input is correctly set.
Fix
Add WebSite JSON-LD schema to the homepage <head>. Set url to the canonical-url homepage URL. Set potentialAction with SearchAction, target pointing to your search results URL with {search_term_string} placeholder, and query-input as required name=search_term_string.
Explain
Explain how the WebSite SearchAction schema works, what the Sitelinks Searchbox is, why Google may choose not to show it even with valid schema, and how to construct the search URL template.
Code Review
Review metadata generation, rendered HTML, structured data, and response headers related to WebSite Search Schema. Flag exact routes or templates where search-facing output violates the rule, and describe how to verify the final page output.
