About

SearchAction is a structured data type from Schema.org that describes a website's search capability.

Before November 2024, it was used by Google to enable the "Sitelinks Search Box" feature, which displayed a search bar for a website directly within the search results snippet. However, since Google deprecated this feature, there is no evidence that other search engines or apps currently support it.

The Speculation Rules API is a browser API that improves navigation performance by prefetching or prerendering pages that users are likely to visit next.

It uses JSON-based rules embedded in HTML or HTTP headers, and is designed as a successor to older techniques such as Prefetch and the deprecated Prerender attribute.
