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 Web Content Accessibility Guidelines (WCAG) are an international standard developed by the W3C that defines how to make web content, including text and media, accessible to people with disabilities.
They are technology-agnostic and structured around four core principles (perceivable, operable, understandable, and robust) and define testable success criteria with three conformance levels (A, AA, AAA) used to evaluate accessibility compliance.
